A study into levels of contamination by organochlorine compounds (insecticides and PCBs) and heavy metals (Cd and Pb) in the water/sediment system of the Southeast Regional Park (SERP) in Madrid, Spain, has been carried out. Residue levels of xenobiotics were determined in surface and underground waters and sediments from selected sites throughout the protected area. The results showed these contaminants to be widespread throughout the studied area. p,p'-DDT concentration levels were consistently higher than its metabolite p,p'-DDE, indicating a recent use of this organochlorine insecticide in the area. PCB levels exceeded, in the majority of the cases, the levels taken as the maximum (100 ng/microl) for highly polluted waters. Cd and Pb levels found in water samples were under the detection limits of the methodology used. Pb levels found in sediment samples were higher than Cd.
针对西班牙马德里东南区域公园（SERP）水/沉积物系统中的有机氯化合物（杀虫剂和多氯联苯）以及重金属（镉和铅）污染水平展开了一项研究。在整个保护区选定地点的地表水、地下水以及沉积物中测定了异生素的残留水平。结果显示，这些污染物在整个研究区域广泛存在。p,p'-滴滴涕的浓度水平始终高于其代谢物p,p'-滴滴伊，这表明该地区近期使用过这种有机氯杀虫剂。在大多数情况下，多氯联苯的水平超过了被视为高污染水体最大值（100纳克/微升）的水平。水样中检测到的镉和铅水平低于所用方法的检测限。沉积物样本中检测到的铅水平高于镉。
