有机氯杀虫剂和多氯联苯（PCBs）的水和沉积物样品取自沿着埃布罗河（西班牙），最农业和工业盆地在伊比利亚半岛北部。测定了10种杀虫剂、多氯联苯和13种多氯联苯同系物的浓度;根据结构亲和力对所有化学品进行分组，其排列顺序如下：多氯联苯>滴滴涕总量>环二烯类杀虫剂总量>六氯环己烷总量。在埃布罗河的主要输入地--河流的中、下游沉积物中检测到较高水平的有机氯污染物。(C)1998爱思唯尔科技有限公司版权所有。
Organochlorine insecticides and poychlorinated biphenyls (PCBs) were measured in water and sediment samples taken from thirteen sites along the Ebro River (Spain), the most agricultural and industrial basin in the North of the Iberian Peninsula. Concentrations of 10 insecticides, PCBs and 13 PCB congeners were determined; grouping all chemicals by structural affinity, these can be arranged in descending order as follow: PCBs > total DDT > total cyclodiene insecticides > total HCH. Higher levels of organochlorine pollutants were detected in sediments from the middle and lower parts of the stream where are located the main important inputs in Ebro River.
