Abstract |
In drinking water sources, quantitative/qualitative analysis about 56 pesticides and over 200 micropollutants was performed using Purge & Trap, Liquid-Liquid Extraction and XAD resin accumulation preconcentration methods and GC/MS. In that results, various contaminants were identified and target organics for treatment could be selected. Contamination of pesticides was severe in rainy season, august and its level exceeds over EC limit(500ng/L). Most domestic drinking water sources were contaminated with a large portion of phthalates, thus the pollution were suspected from wastewater of plastic industries. Nakdong river water was most severe in pollution of CH₂Cl₂ extractable organics, aliphatic hydrocarbons, pesticides, phenols, phthalates and sulfur compounds, therefore this water was found to be polluted by industrial wastewater, agricultural chemicals heavily. |
