Eighteen surface sediment samples representative of the entire Izmir Bay were analyzed for organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs). This was in order to provide extensive information concerning the recent deposition of these compounds in this area, together with levels, distribution, possible sources and potential biological risk. Sites that were contaminated by high concentrations of organochlorine compounds were associated with dense population, such as the harbour and the Gediz River estuary. Relatively higher ΣDDT concentrations and high DDT/DDE+DDD ratios in the Gediz River estuary indicated DDT usage, probably linked to public health emergencies. According to the established guidelines for sediment quality, the risk of adverse biological effects from such levels of OCPs and PCBs as recorded at most of the study sites was insignificant. But the higher concentrations in Inner bay and in the Gediz River estuary could cause biological damage.
对代表整个伊兹密尔湾的 18 个表层沉积物样本进行了有机氯农药（OCPs）和多氯联苯（PCBs）的分析。这是为了提供有关这些化合物在该地区近期沉积的广泛信息，以及水平、分布、可能的来源和潜在的生物风险。受高浓度有机氯化合物污染的地点与人口密集地区有关，如港口和盖迪兹河河口。盖迪兹河河口的ΣDDT 浓度相对较高，DDT/DDE+DDD 比值较高，表明使用了滴滴涕，可能与公共卫生紧急情况有关。根据沉积物质量的既定准则，在大多数研究地点记录的 OCPs 和 PCBs 水平不会导致不良生物影响的风险。但内湾和盖迪兹河口较高的浓度可能会造成生物损害。
