Anthropogenic interference the ecosystem unavoidably changes the physical and biological environment. The biodiversity of the Amazon region has been threatened by increased agricultural production and pesticide use. Considering that monitoring pesticides in environments close to their application is one of the ways to preserve the ecosystem, this study investigated the levels of pesticide residues in different environmental compartments (soil, sediment, and water samples). Thirty-one active ingredients of pesticides of different classes were analyzed by UHPLC-MS/MS. For this purpose, we performed quarterly collections in dry and rainy seasons in the region, which helped to evaluate the impact of pesticides on the biodiversity of the study site. Sampling points were the river banks in the area of an agricultural project in Formoso do Araguaia city, Tocantins State. After analysis, we detected the following substances in the water matrix: clomazone, fluazifop-p-butyl, flutolanil, metsulfuron-methyl, propanil, and imidacloprid. Nevertheless, we did not detect any active ingredient in sediment and soil matrices. The active ingredient clomazone was present in all points in the trials, with concentrations reaching up to 0.538 μg L⁻¹. These substances have potential for groundwater contamination. Even at low concentrations in the aquatic ecosystem, these substances can damage human populations and wildlife species, given their toxicological classification. Thus, the study showed an environmental risk of bioaccumulation and/or biomagnification in the region, which may affect environmental biodiversity as well as human health.

人为干扰生态系统不可避免地会改变物理和生物环境。农业生产和农药使用量的增加已威胁到亚马逊地区的生物多样性。考虑到在接近其应用环境的环境中监测农药是保护生态系统的方法之一，因此本研究调查了不同环境区室（土壤，沉积物和水样）中农药残留的水平。通过UHPLC-MS / MS分析了31种不同类别农药的有效成分。为此，我们在该地区的干燥和雨季进行了季度采集，这有助于评估农药对研究地点生物多样性的影响。采样点是阿拉莫瓜州福莫索的一个农业项目区域内的河岸，Tocantins状态。经过分析，我们在水基质中检测到了以下物质：广灭灵，氟喹氟醚对丁基，氟乙腈，甲磺隆，甲基，吡虫啉和吡虫啉。但是，我们没有在沉积物和土壤基质中检测到任何有效成分。试验中所有部位均存在活性成分广灭灵，浓度最高可达0.538μgL^-1。这些物质可能会污染地下水。鉴于其毒理学分类，即使在水生生态系统中浓度很低，这些物质也可能损害人类种群和野生动植物物种。因此，研究表明该地区存在生物富集和/或生物放大的环境风险，这可能会影响环境生物多样性以及人类健康。
