Application of Cu/Mg/Al-chitosan-O3 system for landfill leachate treatment: Experimental and economic evaluation data.

Landfill leachate contains heavy organic pollutants, which pollute ground and surface waters. This dataset applied a newly-introduced catalyst, Cu/Mg/Al-chitosan, for a landfill leachate treatment during a catalytic oxidation. The data of chemical oxygen demand (COD) and colour removal from the leachate was reported as a function of reaction time (20-460 min). Economic evaluation data of the Cu/Mg/Al-chitosan-O3 system showed that the current cost of the system for treating each m3 leachate is US$ 18 and for catalyst synthesis is US$ 54.5. Data could be useful from environmental and economic perspectives to those concerned about landfill leachate threats.

Urinary arsenic, cadmium, manganese, nickel, and vanadium levels of schoolchildren in the vicinity of the industrialised area of Asaluyeh, Iran.

Asaluyeh is one of the most heavily industrialised areas in the world where gas, petrochemical, and many downstream industries are located. This study aims to survey the biomonitoring of four metals and one metalloid in children living in the vicinity of Asaluyeh area. To do this, we analysed the creatinine-adjusted urinary levels of arsenic (As), cadmium (Cd), vanadium (V), manganese (Mn), and nickel (Ni) in 184 elementary schoolchildren (99 boys and 85 girls) living in Asaluyeh and compared them with a reference population. The comparisons were done for two seasons (spring and fall). The results showed that in the case area (Asaluyeh), the levels of As, V, Mn, and Ni were significantly higher and that of Cd was not significantly higher than the reference city for both seasons. The mean concentration of metal(loid)s in Asaluyeh (case) and Sadabad (reference) area as µg g-1 creatinine was As 2.90 and 2.24, V 0.06 and 0.03, Mn 0.28 and 0.25, Ni 0.54 and 0.29, and Cd 0.31 and 0.28 in spring and As 3.08 and 2.28, V 0.07 and 0.03, Mn 0.30 and 0.26, Ni 0.91 and 0.30, and Cd 0.36 and 0.31 in the fall. Seasonal variations played a key role in determining urinary metal(loid) concentration, as we saw the significant level of As, Cd, V, and Ni in fall than in spring. With regard to the impact of gender on the absorption and accumulation of urinary metal(loid)s, boys showed higher levels of the studied elements, especially for As, than girls as outdoor activities are more popular among boys. Due to the values being lower than those reported in literature, more research is needed on various population groups and other exposure sources in order to judge whether living in the vicinity of the gas and petrochemical industries in Asaluyeh is a threat to nearby residents.

Data on metals biomonitoring in the body of schoolchildren in the vicinity of a heavily industrialized site.

This data is obtained from analyzing the concentration of metals include Al, Co, Cr, Cu, Fe, Mo, Pb, and Zn in the urine of schoolchildren in Asalouyeh city in vicinity to a heavily industrialized site and comparison with a reference city. The significance of sex groups on urine metal level was evaluated through this data. The urinary content of metals was measured by inductively coupled plasma atomic emission spectroscopy (ICP-OES). Statistical analyze of data were done by Mann-Whitney test. The herein presented date could beneficial for health assessment of gas and petrochemical companies.

Evaluation of the knowledge level of health violations in food production, distribution, sales centers and public places and their authorities investigating among the women of Bushehr city.

BACKGROUND: Women and mothers are the most important educational audience to convey health teachings. This study was aimed to evaluate the knowledge level of different types of health violations of food production, distribution, sale centers and public places; and authorities investigating the violations among women referring to health care centers in Bushehr. MATERIALS AND METHODS: In this descriptive-analytical study, which was done cross-sectionally, 600 women who were referred to health care centers affiliated to the Bushehr University of Medical Sciences was selected by convenience sampling. Two-part questionnaire was used to collect data: demographic information and a researcher-designed knowledge survey questionnaire consisted of 25 questions with Cronbach's alpha = 0.7. Data were analyzed with the software SPSS version 13; using Chi-square test and Phi and Cramer test. P ≤ 0.05 was considered to be statistically significant. RESULTS: The findings showed that 56.9% and 26.5% of women had good and moderate knowledge levels regarding health violations, while the general knowledge level of authorities investigating health violations were at the moderate level among 57.3% and at the good level among 15.3% of women. Overall, there was a significant relationship between education level and the women's knowledge level of health violations (P < 0.0001). The relationship between the women's education level and authorities investigating health violations was not significant (P = 0.073). CONCLUSION: Applying interventional methods of education in health violations to the women by health centers can elevate the level of health knowledge among them.
