The survey of chemical agents with related health indicators and respiratory disorder in Do Son Industrial Zone of Hai Phong city
Journal Title: JOURNAL OF FUNCTIONAL VENTILATION AND PULMONOLOGY - Year 2018, Vol 9, Issue 26
Abstract
Objectives. The study was conducted in the residential area of Do Son Industrial Zone in Hai Phong with the objectives: (1) Identification of some chemical agents in the environment around the Do Son industrial zone; (2) Identification of some relevant health indicators including respiratory and other internal diseasesof neighboring populations; (3) Proposed interventions. Methods. It was descriptive and cross sectional study to describe the pollution situation of heavy metals in water sources, drinking water and food samples. This study analyzed the relationship between heavy metal pollution in the environment and some related health indicators in neighboring communities. It also evaluated the efficiency of some water treatment technologies at the laboratory scale. Results. There was arsenic contamination in groundwater: an average arsenic content of 234.07± 140.74 µg/L; 58.7% of households have high levels of arsenic exposure. Related health indicators: No mercury, lead, cadmium, cyanide and chromium were detected in the communities surrounding Do Son. Detection of elevated 24h arsenic, an average concentration of 122.8 ± 70.97 g / L. Of these, 11.6% of arsenic was excreted inorganic and 72.1% was excreted as highly methylated (DMA). There was a significant correlation between arsenic level and exposure, between arsenic and DMA and IA, between clinical symptoms and arsenic levels.Activated charcoal filter from Ricinus communis L plants has the filtration properties of less than 10μg/L of arsenic. Conclusion. The detection of arsenic content in underground water in Do Son industrial area exceeds permitted standard, relating some respiratory symptoms and other health problems. It is possible to use the technology of slow filtration tank with activated charcoal from Ricinus communis L plants to filter arsenic from underground water source for community.
