Water quality degradation by organochlorine pesticides and potentially toxic elements is of worldwide concern. This research explores groundwater conditions, regarding organochlorine pesticides and potentially toxic elements, in Hopelchen, Campeche, which is located in the buffer zone of the Calakmul Biosphere Reserve. Unfortunately, agriculture is allowed and agrochemical use is not monitored and sanctioned. Results show that Heptachlor, Endosulfan, and Dieldrin, all recognized carcinogens, had concentrations above the Mexican normative recommended values. Conversely, Cd and Ni concentrations were below recommended values. These results demonstrate that government intervention involving immediate control over agrochemical use is mandatory. Also, the results underscore the contamination of groundwater in several of the Calakmul Biosphere Reserve’s buffer zones by organochlorine pesticides concentrations, posing a probable threat for local inhabitants who consume this water and use it for recreation.

墨西哥霍普尔琴玛雅地区受保护保护区地下水中的有机氯农药和潜在的有毒元素。

有机氯杀虫剂和潜在的有毒元素对水质的破坏是全世界关注的问题。这项研究探索了位于卡拉克穆尔生物圈保护区缓冲区的坎佩切州霍普尔兴的地下水条件，涉及有机氯农药和潜在的有毒元素。不幸的是，农业是允许的，农药的使用没有受到监控和制裁。结果表明，所有公认的致癌物七氯，硫丹和狄氏剂的浓度都高于墨西哥的标准推荐值。相反，镉和镍的浓度低于建议值。这些结果表明，政府干预必须立即控制农用化学品的使用。也，
