Toward setting public health guidelines for chemicals in indoor settled dust?

Indoor settled dust may result in substantial human exposure to chemicals, especially by ingestion following hand-to-mouth or hand-to-object-to-mouth contact. As with other environmental media related to exposure, dust may thus be subject to regulation. An international scientific workshop was convened in Paris in September 2019 firstly to assess the relevance for public health of setting guidelines for indoor settled dust, and secondly to discuss scientific and technical challenges related to such guidelines. The main discussions and conclusions, with consensus achieved, are reported herein. Discussions concerned general considerations, objectives and definitions, relevance for a health-based guideline, units of measure, and finally derivation of the guideline. These points should be addressed when considering an indoor settled dust guideline as part of a policy to reduce exposure indoors to a given chemical or group of chemicals.

Initial evaluation of the sustainable Jersey for Schools Program and certifications achieved by new Jersey public schools, 2014-2018.

Sustainable Jersey for Schools (SJS) includes free and voluntary certification for New Jersey (NJ) public K-12 districts (SD) and schools. SJS promotes increased awareness for waste and greenhouse gas emissions reductions via energy efficiency and conservation measures; environmental education; equity; etc. SD first register with SJS; school(s) then register and pursue one of two current certification levels, bronze or silver. We conducted an initial external evaluation of successes, challenges and potential barriers faced by SJS registered schools pursuing certification 2014-2018. We also assessed potential associations between registered, certified schools in registered SD-compared to registered, uncertified schools and non-registered schools-and available socio-economic status and socio-demographic indicators using other State of NJ agencies data for five school years within 2014-2019. These included per student costs, number of students per teacher and per administrator, number of teachers per administrator, and average daily enrollment. Future SJS successes and challenges may be determined by political will of registered, certified participants; available paid human resources and contributions of unpaid volunteers; financial and technical resources available. Future evaluation research should expand on our initial non-statistically significant regression analyses on factors influencing SJS re-certification and expired certifications plus challenges in rural and relatively sparsely populated counties.

E-cigarette environmental and fire/life safety risks in schools reported by secondary school teachers.

BACKGROUND: To identify if e-cigarette usage is an on-campus problem for secondary schools and evaluate initial school survey responses. More specifically, this survey can aid in identifying where students are seen using e-cigarettes, if smoke alarms have been newly inserted on school property, if smoke alarms have been tampered with to allow for vaping without detection; and, if any e-cigarette fires or explosions have occurred on school property. METHODS: This survey, disseminated to New Jersey secondary school teachers across seven sessions January-July 2019, resulted in 104 complete responses of 109 respondents. The survey was conducted after fire prevention, exit/egress, and life safety portions of "OSHA 10 Plus for General Industry" courses. Survey questions included number of times teachers observed students vaping and location where vaping in last 12 months, fire alarm installation and tampering, and fires or explosions and injuries from vaping/e-cigarette devices. RESULTS: Many (63%) respondents reported very or moderately common rates of vaping within their schools; however, three of four questions regarding school fire and smoke alarm use specifically to detect vaping had a majority of unsure/I don't know responses. CONCLUSION: Results suggested concerns regarding student vaping and e-cigarette use inside and outside secondary schools. Improved school detection and response are warranted. TRIAL REGISTRATION: Not applicable.

Injuries among young workers in career-technical-vocational education and associations with per pupil spending.

BACKGROUND: New Jersey Department of Education (NJDOE) requires by law for accidents/incidents (injury) involving career-technical-vocational education (CTE) students and staff to be reported within five business days to the NJ Safe Schools Program (NJSS) using an online surveillance system. NJ public schools and charter schools (CS) through school districts (SD) or county offices report school data annually to NJDOE, including per pupil spending (PPS). In this study, we examined potential associations of PPS with several variables on injury in NJ: injury cause, injury location on the body, injury type, injury severity, use of PPE, and location of treatment for injury. METHODS: PPS data for December 1998-June 2015 from CTE SDs (one per NJ county, n = 21), four CS SD and eight county special services districts were analyzed. T-test examined potential differences in PPS regarding injury severity and use of personal protective equipment (PPE). Stepwise logistic regression assessed potential associations between PPS and various injury surveillance variables. RESULTS: There were more CTE injuries reported among SD with lower PPS than among SD with higher PPS. Relatively less severe injuries, e.g., bruise/bumps and cuts/lacerations, more often occurred at schools and SD with higher PPS. Conversely, relatively more severe injuries, e.g., fractures, more often occurred at schools and SD with lower PPS. CONCLUSION: Future research should further investigate disparities regarding younger worker injuries reported within school-based career-technical-vocational education programs by PPS and other factors like sex or gender, severity, safety training provided and work experience at time of injury.

Efficacy of a lead based paint XRF analyzer and a commercially available colorimetric lead test kit as qualitative field tools for determining presence of lead in religious powders.

The performances of a portable X-Ray Fluorescence (XRF) lead paint analyzer (RMD LPA-1, Protec Instrument Corp., Waltham, MA) and a commercially available colorimetric lead test kit (First Alert Lead Test Kit, eAccess Solutions, Inc., Palatine, IL) were evaluated for use by local or state health departments as potential cost-effective rapid analysis or "spot test" field techniques for tentative identification of lead content in sindoor powders. For both field-sampling methods, sensitivity, specificity and predictive values varied widely for samples containing <300,000 µg/g lead. For samples containing ≥300,000 µg/g lead, the aforementioned metrics were 100% (however, the CIs had a wide range). In addition, both field sampling methods showed clear, consistent positive readings only for samples containing ≥300,000 µg/g lead. Even samples with lead content as high as 5,110 µg/g were not positively identified by either field analysis technique. The results of this study suggest the XRF analyzer and colorimetric lead test kit cannot be used as a rapid field test for sindoor by health department inspectors.

Lead Content of Sindoor, a Hindu Religious Powder and Cosmetic: New Jersey and India, 2014-2015.

OBJECTIVES: To assess the extent of lead content of sindoor, a powder used by Hindus for religious and cultural purposes, which has been linked to childhood lead poisoning when inadvertently ingested. METHODS: We purchased 95 samples of sindoor from 66 South Asian stores in New Jersey and 23 samples from India and analyzed samples with atomic absorption spectrophotometry methods for lead. RESULTS: Analysis determined that 79 (83.2%) sindoor samples purchased in the United States and 18 (78.3%) samples purchased in India contained 1.0 or more micrograms of lead per gram of powder. For US samples, geometric mean concentration was 5.4 micrograms per gram compared with 28.1 micrograms per gram for India samples. The maximum lead content detected in both US and India samples was more than 300 000 micrograms per gram. Of the examined US sindoor samples, 19% contained more than 20 micrograms per gram of lead (US Food and Drug Administration [FDA] limit); 43% of the India samples exceeded this limit. CONCLUSIONS: Results suggested continued need for lead monitoring in sindoor in the United States and in sindoor carried into the United States by travelers from India, despite FDA warnings.

Relationship among environmental quality variables, housing variables, and residential needs: a secondary analysis of the relationship among indoor, outdoor, and personal air (RIOPA) concentrations database.

Retrospective descriptive secondary analyses of data from relationships of indoor, outdoor, and personal air (RIOPA) study homes (in Houston, Texas; Los Angeles County, California; and, Elizabeth, New Jersey May 1999-February 2001) were conducted. Data included air exchange rates, associations between indoor and outdoor temperature and humidity, and calculated apparent temperature and humidex. Analyses examined if study homes provided optimum thermal comfort for residents during both heating and cooling seasons when compared to current American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Standards 62/62.1 and 55. Results suggested outdoor temperature, humidex, and apparent temperature during the cooling season potentially served as indicators of indoor personal exposure to parameters of thermal comfort. Outdoor temperatures, humidex, and apparent temperature during the cooling season had statistically significant predictive abilities in predicting indoor temperature. During the heating season, only humidex in Texas and combined data across study states were statistically significant, but with weaker to moderate predicative ability. The high degree of correlation between outdoor and indoor environmental variables provided support for the validity of epidemiologic studies of weather relying on temporal comparisons. Results indicated most RIOPA study residents experienced thermal comfort; however, many values indicated how several residents may have experienced some discomfort depending on clothing and indoor activities. With climate change, increases in temperature are expected, with more days of extreme heat and humidity and, potentially harsher, longer winters. Homes being built or modernized should be created with the appropriate guidelines to provide comfort for residents daily and in extreme weather events.

Injury surveillance and associations with socioeconomic status indicators among youth/young workers in New Jersey secondary schools.

BACKGROUND: Injuries involving career-technical-vocational education (CTE) are reported to the New Jersey Safe Schools Program online reporting system, the only U.S. State law-based surveillance data for young workers (ages twenty-one and younger), a susceptible, vulnerable adolescent sub-population. METHODS: We examined potential associations between socioeconomic status (SES) indicators and high school student injuries reported between 12/1998-12/2013, excluding injuries acquired by staff members. Associations between DFG score-a proxy for school/district SES-and variables relating to reported injuries, including severity, injury type, injury cause, body parts injured, injury treatment setting and demographics were examined with chi square test (X(2)) for independence and logistic regression. To assess potential associations between SES and personal protective equipment (PPE), data were stratified by 2003-2008 and 2008-2013, given mandated payment by employers of PPE for employees. RESULTS: Statistically significant associations were found between SES and injury cause [X(2) = (7, 14.74), p = 0.04] and SES and injury treatment setting [X(2) = (1, 4.76), p = 0.03]. Adjusted odds ratio suggested students from low SES schools were at a higher odds of being treated at a hospital emergency department (ED) than students from high SES schools (95 % CI 1.3-4.3, p < 0.01). CONCLUSIONS: These findings indicated low SES schools/districts have increased odds of being treated at ED, after controlling for injury severity. Future research should focus on implications such associations have on health care access and insurance for young workers and their families. With small sample sizes representing lower DFG scoring (SES) schools/districts, additional efforts should be enacted to increase injury reporting in these schools/districts.

Spatial-temporal variations in carbon dioxide levels in Ibadan, Nigeria.

Growing evidence suggests how global background levels of atmospheric carbon dioxide (CO2) are increasing and this impacts environmental quality and human and ecological health. Data from less developed countries are sparse. We determined spatial and temporal variations in concentrations of CO2 in selected locations in Ibadan, Nigeria with identifiable prominent outdoor sources. Activity driven areas in north and south-west areas were identified and marked with a global positioning system. Waste management practices and activities generating CO2 were documented and described using a technician observation checklist. CO2 levels were measured using a portable TELAIRE 7001 attached to HOBO U12 data loggers across seasons. Mean CO2 levels were compared over seasons, i.e. rainy season months and the dry season months. While CO2 levels recorded outdoors in study areas were comparable to available international data, routine monitoring is recommended to further characterize concurrent pollutants in fossil fuel combustion emissions with known deleterious health effects.

Exposure to electric power generator noise among small scale business operators in selected communities in Ibadan, Nigeria.

Inadequate and erratic power supplies mean small businesses use electric generators for alternative power. The authors' goal in the study described here was to assess noise from electric generators and impacts in the commercial areas of Agbowo and Ajibode in Ibadan, Nigeria. Noise levels (A-weighted decibels [dBA]) were measured over 12 weeks, three times a day, during the 2010 dry season using a sound level meter. A questionnaire was administered (515 respondents; 304 in Agbowo, 211 in Ajibode) and audiometric measurements were conducted on 40% of respondents. Mean noise levels varied by source (104 ± 7.7 dBA [diesel], 94.0 ± 6.3 dBA [petrol]) and were highest midday (90.6 ± 5.3 dBA [Agbowo], 70.9 ± 6.2 dBA [Ajibode]). Mean noise levels in Agbowo (78.5 ± 3.9 dBA) and Ajibode (65.7 ± 4.4 dBA) exceeded World Health Organization guidelines (65 dBA) for outdoor commercial environments. Working and living in Agbowo was significantly associated with current evidence of hearing impairment (odds ratio: 6.8, 95% confidence interval: 3.4-13.7). Reducing exposure to noise from electric power generators serving urban small businesses and homes is warranted.

Perspectives and Attitudes of Newer New Jersey High School Teachers towards Cleaning, Sanitizing, and Disinfecting Consumer Products Used in School Classrooms.

During the COVID-19 pandemic, there was an increased reported use of chemical cleaning, sanitizing, and disinfecting products (CSDPs), which created public concerns about negative health consequences for both children and adults in public schools. A subset of newer teachers shared experiences regarding safety and health (S&H) while working in school-based settings through a series of online surveys. Surveys were provided to teachers who completed work-based learning supervisory trainings provided by the New Jersey Safe Schools Program between October 2021 and June 2023. The participants answered questions focusing on CSDPs purchased for school use, their attitudes towards CSDPs, their use of personal protective equipment, and symptoms employees may have had due to CSDPs. A total of 205 teacher participants successfully completed the surveys. Over 25% of the teachers did not know where their CSDPs originated from, as they were provided by the school. Most participants "sometimes", "not often", or "never" read labels for CSDP ingredients or looked them up on healthy product apps. The participants (60%) tended to wear gloves while cleaning/disinfecting but did not wear masks. A third of the participants experienced respiratory health problems after working at school. Overall, the data suggest that more education on S&H regarding CSDPs needs to be provided to New Jersey teachers.

Physical conditions of a house and their effects on measured radon levels: data from Hillsborough Township, New Jersey, 2010-2011.

Concentrations of radon in homes are thought to be dependent on several factors, including the presence of certain physical conditions of the house that act as entry points for this colorless, odorless gas. Drains and sump pits are currently sealed as part of radon mitigation, but doing so may cause drainage problems and mold. The authors attempted to determine if specific attributes and physical conditions of homes are associated with measured residential concentrations of radon. Radon tests were conducted in 96 participating homes in rural Hillsborough Township, New Jersey, November 2010-February 2011. Samplers were placed and a walk-through survey was conducted. Test devices were analyzed by a New Jersey certified radon testing laboratory and results compared to survey data. Overall, 50% of houses with a perimeter drain and 30% of houses with a sump pit exceeded the New Jersey and federal radon action level of 4.0 picocuries per liter, and 47% of homes with both a sump and a perimeter "French" drain exceeded this action level. The authors' results suggested certain physical conditions act as pathways allowing radon entry into homes. Results could be used by local and state agencies to start local initiatives, e.g., increased testing or to seal these components as partial mitigation.

Survey of New Jersey K-12 Professionals on Work-Based Learning During COVID-19: A Preliminary Study and Future Implications.

BACKGROUND: The New Jersey Safe Schools Program (NJSS) offers an online professional development certification course, titled "Designing and Implementing Student Training Plans," for NJ high school (HS) teachers developing secondary school student work-based learning (WBL) programs. WBL provides students opportunities to engage in career-related field tasks, aligned to curricular instruction. METHODS: In January-July 2021, during 7 cohorts of trainings, questions in the training's assignment gauged teacher and student concerns regarding worksite placements during the COVID-19 pandemic, learning delivery format preferences, and alternative activities for WBL credit. RESULTS: In January-July 2021, 68 of 134 HS teachers (51%) were concerned placing students in WBL and indicated "no" and "I don't know" (37% and 31%, respectively) about employer willingness to offer virtual mentorship during the pandemic. CONCLUSIONS: This preliminary study presents insights of newly credentialed WBL supervisory HS teachers regarding impacts of COVID-19 on student health and workplace safety, preferred WBL formats, and potential implementation of COVID-19 safety trainings.

COVID-19 Vaccine Hesitancy among New Jersey Teachers and Impacts of Vaccination Information Dissemination.

Vaccine hesitancy continues to be prevalent in the United States, especially in relation to the COVID-19 vaccines and its boosters, which have been made increasingly available for public use as the pandemic has progressed. There continues to be concern surrounding the safety and health of secondary or high school education professionals as they transition back to in-person learning and working opportunities. The present study highlights how information dissemination regarding the COVID-19 vaccine has varied among New Jersey secondary or high school teachers throughout the pandemic. The survey was completed online through the PsychData platform by 269 participants between March and July 2022. Participants received the opportunity to complete the survey via email. Afterwards, data were exported and analyzed using Microsoft Excel and SAS 9.4 Analytics Software and stratified by various clinical and demographic-based variables. While trusted agencies and media outlets identified by participants varied, most participants identified the Centers for Disease Control and Prevention (65.4%), primary care providers (37.5%), and state health departments (28.6%) as their top trusted sources for information related to COVID-19 vaccines. Overall, COVID-19 vaccination advocacy and educational efforts should continue across the state of New Jersey and elsewhere, especially as more variants emerge and boosters become available.

Factors Associated with COVID-19 Vaccine Hesitancy and Case Status among New Jersey Secondary Educational Professionals.

BACKGROUND: Vaccine hesitancy remains a societal problem, including during the COVID-19 pandemic. New Jersey (NJ) Safe Schools Program provides work-based learning training to supervisory-level career-technical-vocational education teachers and administrators who have to consider varied state and local mandates concerning COVID-19 vaccination and exemptions. METHODS: In early 2022, we distributed an online survey via PsychData to individuals trained between 2014 and 2022 to understand NJ teachers' practices and concerns regarding COVID-19 vaccines. Overall, 269 completed the survey. We stratified data by vaccination status, number of doses, booster status, age, teaching experience, gender, race, county of work, and COVID-19 diagnosis status. RESULTS: Overall, results suggested differences in COVID-19-related concerns, including access to, perceptions of, and confidence in COVID-19 vaccines and COVID-19-related practices. About 90.7% received the initial vaccine; 77.7% received the booster. About half the participants had received a positive COVID-19 diagnosis by the time of the survey; they were less likely to get the vaccine or booster if they had received the initial vaccine. CONCLUSIONS: Data suggested differences in levels of COVID-19-related concerns and confidence in, or importance of, vaccines when comparing different demographic factors and vaccination practices. The data informs efforts to understand factors affecting vaccine hesitancy among educational professionals.

Knowledge, Attitudes, and Awareness of New Jersey Public High School Students about Concepts of Climate Change, including Environmental Justice.

Increasing acknowledgement of climate change (CC) has encouraged various responses, such as education standard mandates. In 2021, New Jersey (NJ) became the first U.S. state to require K-12 CC education across subjects, effective fall 2022. This necessitated introductory science courses on CC to support high school (HS) curricula. Thus, NJ Safe Schools Program (NJSS) created a new course titled, "Introduction to HS Students to CC, Sustainability, and Environmental Justice (EJ)." Given that the COVID-19 pandemic continues (2020-2023 school years) and vaccination coverage varies, this course was developed and approved in an asynchronous online format. Its five modules cover environmental science, CC, natural disasters and extreme weather events, sustainability, including energy conservation and efficiency definitions, and EJ. A 20-question survey included at the end, modified/adapted from a larger nationwide U.S. Student Conservation Association (SCA) survey 2019-2020, examined the perspectives of HS students concerning CC. Selected volunteer NJ HS enlisted students (n = 82/128 finished) to pilot this course February-April 2022. Results such as average scores ≥90% suggested success regarding initial knowledge and awareness gained; for individual modules, two knowledge checks >80% and three knowledge checks >90%. The SCA survey results, overall and by region in NJ, highlighted how most students felt about CC and extreme weather events, plus issues such as EJ. This NJSS introductory course opened in July 2022 for NJ public county secondary school districts and comprehensive HS with approved career-technical education programs, and potentially elsewhere.

Associations between quantitative measures of fungi in home floor dust and lung function among older adults with chronic respiratory disease: a pilot study.

OBJECTIVE: Many fungi may cause allergic reactions and increase asthma symptoms prevalence and severity. One susceptible, vulnerable population subgroup of increasing size in industrialized countries and of public health concern who spends the majority of their time at home is older adults. Older adults diagnosed with chronic obstructive pulmonary disease (COPD) are at risk of exposure to fungi. Currently, species identification is based on observation of microscopic and macroscopic morphologies, which may underestimate concentrations compared to quantitative polymerase chain reaction (qPCR)-based measurements which are toxicologically more relevant to exposure science. METHODS: This article analyzes quantitative indoor exposure data on fungi in floor dust (cells/cm(2) floor) by real-time qPCR-based detection with quantitative outcome data via field spirometry in a pilot community-based study in Visalia, Tulare County, California, between July 2009 and January 2010. Subjects (n = 9, five females, four males) were Caucasian, English-speaking, nonsmoking older adults with doctor-diagnosed asthma and/or COPD. RESULTS: While certain results did not reach statistical significance (p ≤ .10) due to sample size-overall and by gender-we found consistent trends and statistically significant associations for total fungal DNA (summer data) with forced vital capacity and forced expiratory volume in 1 second. CONCLUSIONS: The results of this pilot study are novel and suggest adverse effects of exposure inside homes to certain fungal species. This pilot study supports the need for larger prospective epidemiologic studies of older adults with asthma and/or chronic bronchitis based on quantitative environmental and clinical measures.

COVID-19 School vs. Community-Based Outbreak Trends among New Jersey K-12 Schools during the 2020-2021 School Year.

Identifying potential rapid methods to track COVID-19 trends within schools has become a necessity in understanding how to provide both education and maintain health and safety during a pandemic. This study examined COVID-19 trends and sociodemographic information in New Jersey (NJ) schools during the 2020-2021 school year. A database was compiled for this study in Microsoft Excel using various state and federal resources. Data used in the study are a combination of extracted data from weekly NJ Spotlight reports, weekly NJ COVID-19 Activity Level Index (NJ CALI) reports, and reports of school-based outbreaks via the NJ Department of Health (NJDOH). In 2020-2021, in NJ K-12 schools, the NJDOH defined a school-based outbreak incidence as two or more students and/or adult staff with a laboratory-confirmed positive molecular test for COVID-19 based on transmission occurring on campus. Data were organized into six regions across 21 counties within NJ (3-4 counties per region per NJDOH). COVID-19 trends in NJ schools mirrored trends in their districts, i.e., communities, within the state's region; noticeably, there were consistently high trends during the winter holiday season (November 2020-January 2021). The cumulative number of incidences of school-based outbreaks remained relatively low but, nevertheless, increased throughout the 2020-2021 school year. This study recommends increased accessibility to COVID-19 reports for school and public health officials, and in the future for data to be reported to identify rates of transmission of other communicable diseases within K-12 students, and to further reinforce established mandates and other preventative measures in public while traveling during holiday seasons.

Absence, extended absence, and repeat tardiness related to asthma status among elementary school children.

BACKGROUND: The purpose of this analysis was to examine potential associations between absence, extended (repeated) absence, tardiness, and repeated tardiness from school and doctor-diagnosed asthma. METHODS: A cross-sectional analysis was conducted using data collected in fall 2007 on 914 4th and 5th grade school children from seven randomly selected participating schools in DeKalb County, GA. ANOVA was used to compare attendance metrics for race, gender, and asthma status groups. Nonparametric Kruskal-Wallis statistical tests were also done because distributions of attendance metrics were skewed. We tallied daily absence data during the study period and examined absence by day of week. We also compared the variation of the weekly rate of absence and tardiness for students with asthma versus students without asthma over the study period. RESULTS: The mean days of absence in 86 students with asthma was 2.73 days compared with 1.89 days for 828 children without asthma (p = .004). There was no significant difference in mean days of tardiness by asthma status. The difference in the number of instances of 2+ consecutive days of absence (extended absence) by asthma status was not significant. Students with asthma were more likely to be absent on Mondays (p = .005), Tuesdays (p = .001), and Fridays (p = .02) than students without asthma. The weekly rate of tardiness for students with asthma trended with the general student study population over the study period, whereas the weekly rate of absence did not. CONCLUSIONS: Asthma was associated with increased 1-day absences but not longer absences or tardiness.
