A comprehensive survey of the occurrence of organic compounds in 30 wastewater (WW) effluent samples from 21 urban wastewater treatment plants (WWTPs) from both secondary and tertiary treatments was carried out in the Mediterranean and Atlantic basins of the Andalusia region (south of Spain). For each sample, a total of 226 compounds including pesticides and some transformation products, polycyclic aromatic hydrocarbons (PAHs), phenolic compounds and volatile organic compounds (VOCs) were monitored with the aim of evaluating their occurrence in urban WW effluents. Compounds belonging to each class were detected. Among pesticides, insecticides such as clorfenvinphos and diazinon as well as herbicides such as diuron, sebuthylazine, terbuthylazine and terbuthylazine desethyl were the most frequently detected. The ubiquity of some compounds such as fluorene, phenanthrene and pyrene was also demonstrated. The compounds evaluated were detected at low concentrations (in general below 1 μg L(-1)), except 4-tert-octylphenol, which was detected at extremely high concentrations (up to 443 μg L(-1)). PAHs and VOCs were the compounds most frequently detected in the assayed samples, and they are the main sources of contamination in WWTPs, as well as some herbicides and transformation products.
对来自西班牙南部安达卢西亚地区（地中海和大西洋盆地）的 21 个二级和三级处理城市污水处理厂（WWTP）的 30 个废水（WW）出水样本中的有机化合物的发生情况进行了全面调查。对于每个样本，共监测了 226 种化合物，包括农药和一些转化产物、多环芳烃（PAHs）、酚类化合物和挥发性有机化合物（VOCs），目的是评估它们在城市 WW 废水中的存在情况。检测到属于每类的化合物。在农药中，氯酚磷和二嗪农等杀虫剂以及敌草隆、塞布特嗪、特丁津和特丁津去乙基等除草剂是最常检测到的。还证明了一些化合物的普遍性，如芴、菲和芘。评估的化合物以低浓度（通常低于 1μg/L）存在，除了 4-叔辛基苯酚，其浓度极高（高达 443μg/L）。在所检测的样品中，多环芳烃和 VOCs 是最常检测到的化合物，它们是 WWTP 的主要污染源，以及一些除草剂和转化产物。
