文章引用了一项研究，分析了墨西哥格雷罗佩塔卡尔科湾沿海沉积物中持久性有机氯农药（POP）的污染水平。研究结果表明，对所研究的四个次区域的持久性有机污染物地理分布情况进行的评估表明，在任何抽样中，这些次区域之间均无显著差异。然而，特别是佩塔卡尔科镇这一次区域，旱季和雨季之间存在重大差异，这反映在持久性有机污染物的总浓度上，尤其是七氯和异狄氏剂的总浓度上。
The article cites a study conducted to analyze levels of pollution derived from the presence of persistent organochlorine pesticides (POPs) in coastal sediments of Petacalco Bay, Guerrero, Mexico. Results of the study revealed that assessment of the geographical distribution of POPs in the four studied subregions revealed no significant differences among them in any of the samplings. However, in particular, the subregion, Petacalco Town, depicted important differences between the dry and the rainy season, which was reflected in the total concentration of POPs and especially in that of heptachlor and endrin.
