The effects on mortality and the associated financial costs of wood heater pollution in a regional Australian city.

OBJECTIVES: To estimate the annual burden of mortality and the associated health costs attributable to air pollution from wood heaters in Armidale. DESIGN: Health impact assessment (excess annual mortality and financial costs) based upon atmospheric PM2.5 measurements. SETTING: Armidale, a regional Australian city (population, 24 504) with high levels of air pollution in winter caused by domestic wood heaters, 1 May 2018 - 30 April 2019. MAIN OUTCOME MEASURES: Estimated population exposure to PM2.5 from wood heaters; estimated numbers of premature deaths and years of life lost. RESULTS: Fourteen premature deaths (95% CI, 12-17 deaths) per year, corresponding to 210 (95% CI, 172-249) years of life lost, are attributable to long term exposure to wood heater PM2.5 pollution in Armidale. The estimated financial cost is $32.8 million (95% CI, $27.0-38.5 million), or $10 930 (95% CI, $9004-12 822) per wood heater per year. CONCLUSIONS: The substantial mortality and financial cost attributable to wood heating in Armidale indicates that effective policies are needed to reduce wood heater pollution, including public education about the effects of wood smoke on health, subsidies that encourage residents to switch to less polluting home heating (perhaps as part of an economic recovery package), assistance for those affected by wood smoke from other people, and regulations that reduce wood heater use (eg, by not permitting new wood heaters and requiring existing units to be removed when houses are sold).

Residual Inequity: Assessing the Unintended Consequences of New York City's Clean Heat Transition.

Energy policies and public health are intimately intertwined. In New York City, a series of policies, known as the Clean Heat Program (CHP), were designed to reduce air pollution by banning residual diesel fuel oils, #6 in 2015 and #4 by 2030. This measure is expected to yield environmental and public health benefits over time. While there is near-universal compliance with the #6 ban, a substantial number of buildings still use #4. In this paper, geographic analysis and qualitative interviews with stakeholders were used to interrogate the CHP's policy implementation in Northern Manhattan and the Bronx. A total of 1724 (53%) of all residential residual fuel burning buildings are located in this region. Stakeholders reflected mostly on the need for the program, and overall reactions to its execution. Major findings include that government partnerships with non-governmental organizations were effectively employed. However, weaknesses with the policy were also identified, including missed opportunities for more rapid transitions away from residual fuels, unsuccessful outreach efforts, cost-prohibitive conversion opportunities, and (the perception of) a volatile energy market for clean fuels. Ultimately, this analysis serves as a case study of a unique and innovative urban policy initiative to improve air quality and, consequently, public health.

Have winter fuel payments reduced excess winter mortality in England and Wales?

BACKGROUND: The historical series of excess winter mortality (EWM) in England and Wales presents a negative trend. Winter fuel payments (WFPs) are the most important benefits for people aged 65 or over directly related to Winter Mortality in the UK. METHODS: This study presents a time series analysis of the direct effect of WFPs on EWM in England and Wales. RESULTS: We find a significant structural break in trend and volatility in the EWM series in England and Wales in 1999-2000. After controlling for a number of covariates, an ARIMA-X model finds that WFPs can account for almost half of the reduction in EWM in England and Wales since 1999/2000. CONCLUSIONS: Almost half of the reduction in EWM since 1999/2000 is attributable to WFPs.

[Carbon monoxide poisoning from a legal natural gas installation]. / Kulilteforgiftning ved lovlig naturgasinstallation.

Natural gas has been used in Denmark for 12 years and many installations are old and need an overhaul. A carbon monoxide-poisoning accident caused by a legally installed and maintained natural gas installation is described.

Tap water burn prevention: the effect of legislation.

Five years after a 1983 Washington State law required new water heaters to be preset at 49 degrees C (120 degrees F), 77% of homes (84% of homes with postlaw and 70% of homes with prelaw water heaters) had tap water temperatures of less than 54 degrees C. In 1977, 80% of homes had tap water temperatures greater than 54 degrees C. Mean temperature in 1988 was 50 degrees C compared with 61 degrees C in 1977. Both changes were significant compared with 1977 temperatures. Few people increased their heater temperature after installation. Eighteen burn victims were identified from July 1979 through May 1988, for an average admission rate of 2.4 per year, compared with 5.5 per year in the 1970s. Compared with the 1970s, total body surface area burned, mortality, grafting, scarring, and length of hospital stay were all reduced, while the likelihood that scald burns were the result of child abuse increased to 50%. Both education campaigns and legislation have resulted in significantly safer water temperatures. Further, this change seems to have resulted in a reduction in frequency, morbidity, and mortality of tap water burn injuries in children. Lower water heater settings proved acceptable to the consumer.

[Fatal risks in the domestic use of gaseous hydrocarbons examined in the light of legislation in force]. / Il rischio mortale nell'uso domestico degli idrocarburi gassosi alla luce della legislazione vigente.

The authors, in order to identify the causes of mortal poisonings by carbon monoxide in the domestic use of gaseous hydrocarbons and to evaluate the efficacy of the inherent law in force, in particular, the italian law 5 March 1990, n. 46, report 43 cases of mortal poisoning occurred in the Parma district and observed at the Istituto di Medicina legal of Parma University. The authors, for each of these cases, have pointed out responsibilities, causal factors and mechanisms, examining also judicial inquiries and, when possible, experts' technical reports. From the evaluation of the results of their researches, the authors, even if with some perplexity, judge the law in force as suitable to a correct prevention, but only on condition that the controls provided for in law, should be actually carried out. Finally, they evidence a lacking of publicizing about the mortal risk deriving from the non-observation of the legal regulations.
