Recent advances in analytical techniques allow identifying pesticide pollution in water systems. In small rural communities, the negative effects of pesticide pollution can be aggravated by the lack of infrastructure and adverse socioeconomic conditions. This study investigated pesticide pollution in potential water supply sources in a tomato growing area in Paty do Alferes, Rio de Janeiro State, Brazil. The study selected 27 points where five monthly samples were collected. Pesticide pollution was determined by analyzing acetyl-cholinesterase inhibition. In 19 of the 27 sample points, some pesticide pollution was detected, and in two points the pesticide pollution was above the permitted limits. The results thus proved the incidence of pesticide pollution in water sources in Paty do Alferes that could jeopardize the local population's health.
分析技术的最新进展使得能够识别水系统中的农药污染。在小型农村社区，基础设施的缺乏和不利的社会经济条件会加剧农药污染的负面影响。本研究调查了巴西里约热内卢州帕蒂杜阿尔费雷斯一个番茄种植区潜在供水水源中的农药污染情况。该研究选取了27个采样点，每月采集5次样本。通过分析乙酰胆碱酯酶抑制作用来确定农药污染情况。在27个采样点中的19个检测到了一些农药污染，在两个采样点农药污染超过了允许限值。结果证明了帕蒂杜阿尔费雷斯水源中存在农药污染，这可能危及当地居民的健康。
