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.
水质因有机氯农药和潜在有毒元素的退化受到全世界的关注。本研究探讨了位于卡尔克穆尔生物圈保护区缓冲区的坎佩切州霍佩尔琴地下水的有机氯农药和潜在有毒元素状况。不幸的是，农业在这里是被允许的，但是并没有对农用化学品的使用进行监测和制裁。研究结果表明，滴滴涕、硫丹和狄氏剂等均为公认的致癌物质，其浓度均超过了墨西哥推荐值。相反，镉和镍的浓度低于推荐值。这些结果表明，政府必须进行干预，立即控制农用化学品的使用。此外，研究结果还强调了有机氯农药浓度对卡尔克穆尔生物圈保护区多个缓冲区地下水的污染，这可能对当地居民构成威胁，因为他们饮用这些水并将其用于娱乐。
