RESUMO

According to studies, high concentration of fluoride in drinking water has adverse health effects such as dental and skeletal fluorosis. This data analyzes the concentrations and health risks of fluoride in 30 drinking water samples collected from 11 villages of the Khash city, Sistan and Baluchistan province in Iran. Fluoride concentration was measured using SPADNS method according to the standard method for examination of water and wastewater. Data indicated that average fluoride concentration in drinking water was 0.731 mg L-1. The mean estimated daily intake (EDI) values for fluoride in different groups of infants, children, teenagers and adults were 0.0058, 0.0414, 0.0292 and 0.0234 mg/kg, respectively. Also, risk assessment data indicated that hazard quotient (HQ) value of groundwater samples was less than one in 90% of samples in age groups of infants, children, teenagers and adults.

RESUMO

The main objective of this data was determination of the nitrate concentration and its health risk assessment in the drinking water resources. In the aim of this data article a number of 30 samples of nitrate concentration in drinking water resources were collected from villages of the Khash city, Sistan and Baluchistan province, Iran. The nitrate concentration was measured using a Spectrophotometer accordance standard methods for examination of water and wastewater. Data indicated that nitrate concentration in drinking water ranged from 6 to 35 mg/L (average 16.083 mg/L). The mean EDI values for nitrate in different groups of infants, children, teenagers and adults were 0.1287, 0.9114, 0.6433 and 0.5155 mg/Kg, respectively. The findings of data showed that HQ value was less than 1 in 96% of samples in age groups of infants, children, teenagers and adults.

RESUMO

Among the pharmaceutical compounds, antibiotics have been paid specific consideration, due to their acute and chronic toxic effects on organisms. Amoxicillin (AMX) is used widely for treatment of bacterial infections. About 80% of amoxicillin excreted unchanged and enters the aquatic environment through different routes including disposal of municipal wastewaters, hospital wastewaters and farm wastewaters. In this study degradation of amoxicillin by UV/Na2S2O8/FeS2 process was evaluated. According to the results, the R-squared and adjusted R-squared were 0.9877 and 0.9828, respectively. The AMX removal efficiency was 93% at optimum conditions. Thus, UV/Na2S2O8/FeS2 process is a useful process for amoxicillin removal.

RESUMO

Among drugs, antibiotics have a significant place due to their wide consumption in veterinary and human medicine to prevent and treat microbial infections. In spite of low amounts of antibiotics in the aquatic environments, the repeated incidence of antibiotics has been caused bacterial persistence and adverse effects on health human and aquatic life. Current article evaluated the removal of metronidazole (MNZ) via heterogeneous electro-Fenton (EF) process by nano-Fe3O4. The response surface methodology (RSM) on Box-Behnken design was applied for modeling and optimization experimental factors such as pH, applied current, and catalyst load. The efficiency of the EF process was maximum (92.26%) under the optimal condition for MNZ removal i.e. 70 mg/L of initial MNZ concentration, pH of 3, 200 mA applied current, 30 min time and 3.2 kWh/m3 of energy consumption.

RESUMO

The main of this data was determine the concentrations and health risks of fluoride in 66 drinking water samples collected from villages of the Iranshahr city, Sistan and Baluchestan Province in Iran. Fluoride concentration was measured by the standard SPADNS method. Data indicated that fluoride concentration in drinking water ranged from 0.25 to 1.72 mg L-1 and average of fluoride concentration was 0.27 mg L-1. The mean estimated daily intake (EDI) values for fluoride in different groups of infants, children, teenagers and adults were 0.0021, 0.0151, 0.0107 and 0.0086 mg/kg, respectively. Also, risk assessment data indicated that hazard quotient (HQ) value of groundwater samples is more than 1 in 6% of groundwater samples in age groups of children and teenagers.

RESUMO

The data of this research was the investigation of knowledge, attitude and practices of biomedical waste management among healthcare staff and performed in some general hospitals in Tehran, Iran. In this descriptive data, 162 participants were chosen according to stratified sampling method and a self-made questionnaire was used for data collection. Also, Kruskal-wallis test, Mann -Whitney U tests and Spearman correlation coefficient were used to analyze the data in R software, version 3.4.4. The weighted mean of data showed that the knowledge level in staff is "Low" and their activity level is "Moderate". Also, the data of the statistical analysis revealed that there is no significant difference between male and female health care personnel in knowledge, attitude and practices. However, the results of Kruskal-Wallis test showed that there was no significant difference between the views of hospital staff in occupational and educational groups about knowledge and attitude and their relationship with the history of passing the health course, while the difference in practices level was significant (P < 0.0001). Furthermore, the relation between attitude and practices level of participants with different work experience were not significant.
