This is a cross-sectional study with data and biological material collection from vineyard farmers in southern Brazil. An interview was carried out through a questionnaire developed according to the reference guide of the state government. Plasma and urine samples were screened for Aluminum, Chromium, Manganese, Copper, Nickel, Cobalt, Zinc, Arsenic, Selenium, Cadmium, Antimony, Barium, Mercury, Lead and Uranium, with a technique for fast determination of these elemental contents in biological material utilizing dynamic reaction cell inductively coupled mass spectrometry. Principal component analysis was used to identify associations between these elemental contents in biological samples and the information obtained from the interviews. The farmers showed some trace elements in plasma and urine at a higher concentration than unexposed populations from other studies. This study highlights recent findings of trace elements in biological material and their association with characteristics of pesticide use. In addition, it also contributes to the gap in the literature regarding trace elements content in plasma and urine of workers exposed to pesticides.

巴西南部职业接触农药的葡萄园农民的血浆元素含量和尿排泄量

这是一项横断面研究，收集了来自巴西南部葡萄园农民的数据和生物材料。访谈是通过根据州政府的参考指南制定的问卷进行的。对血浆和尿液样本进行铝、铬、锰、铜、镍、钴、锌、砷、硒、镉、锑、钡、汞、铅和铀的筛查，采用快速测定生物材料中这些元素含量的技术利用动态反应池电感耦合质谱。主成分分析用于确定生物样品中这些元素含量与从访谈中获得的信息之间的关联。农民在血浆和尿液中发现一些微量元素的浓度高于其他研究中未暴露人群的浓度。这项研究强调了生物材料中微量元素的最新发现及其与农药使用特征的关联。此外，这也造成了文献中关于接触农药的工人血浆和尿液中微量元素含量的空白。
