A study on the quality of water abstracted for potable use was conducted in the Selangor River basin from November 2008 to July 2009. Seven sampling sites representing the intake points of water treatment plants in the basin were selected to determine the occurrence and level of 15 organochlorine pesticides (OCPs), six phthalate esters (PAEs) and bisphenol A (BPA). Results indicated OCPs were still detected regularly in 66.1 % of the samples with the Σ(15)OCPs ranging from 0.6-25.2 ng/L. The first data on PAEs contamination in the basin revealed Σ(6)PAEs concentrations were between 39.0 and 1,096.6 ng/L with a median concentration of 186.0 ng/L while BPA concentration ranged from <1.2 to 120.0 ng/L. Although di-n-butyl phthalate was detected in all the samples, concentrations of di-ethyl(hexyl)phthalate were higher. Sampling sites located downstream recorded the highest concentrations, together with samples collected during the dry season. Comparison of the detected contaminants with the Department of Environment Water Quality Index (DOE-WQI) showed some agreement between the concentration and the current classification of stream water. While the results suggest that the sites were only slightly polluted and suitable to be used as drinking water source, its presence is cause for concern especially to the fragile firefly "Pteroptyx tener" ecosystem located further downstream.
2008 年 11 月至 2009 年 7 月对雪兰莪河流域的饮用水进行了水质研究。选择了代表流域内水处理厂取水点的 7 个采样点，以确定 15 种有机氯农药（OCPs）、6 种邻苯二甲酸酯（PAEs）和双酚 A（BPA）的发生和水平。结果表明，66.1%的水样中仍定期检测到 OCPs，Σ（15）OCPs 浓度范围为 0.6-25.2ng/L。这是首次对该流域的 PAEs 污染进行研究，结果表明 Σ（6）PAEs 浓度范围为 39.0-1096.6ng/L，中位数浓度为 186.0ng/L，BPA 浓度范围为<1.2-120.0ng/L。尽管所有水样中均检测到邻苯二甲酸二丁酯，但邻苯二甲酸二（乙基己基）酯的浓度更高。下游采样点的浓度最高，而且在旱季采集的水样浓度也最高。与环境部水质指数（DOE-WQI）相比，所检测到的污染物与现行溪流水质分类具有一定的一致性。虽然结果表明这些地点只是轻微污染，适合作为饮用水源，但考虑到下游脆弱的萤火虫“Pteroptyx tener”生态系统，其存在仍令人担忧。
