丹绒卡朗，雪兰莪州，以其水稻种植活动而闻名，拥有马来西亚第三大稻田。由于农药是提高水稻产量和减少植物病害的重要手段，农田农药污染已成为一个不可避免的问题。人类接触农用化学品很常见，可能导致急性和慢性健康影响，例如急性和慢性神经毒性。本研究旨在测定稻田农民个人空气样本中常用农药（氮唑虫胺、丁丙嗪、氯虫腈、异丙康唑、氟虫腈、咪氯虫啉、异丙硫烷、苯甲草胺、丙环康唑、吡吡嗪、戊唑唑、三环唑和三氯虫胺）的浓度及其相关健康风险。来自雪兰莪州Tangjung Karang的83名农民参与了这项研究。一根固体吸附剂管用夹子固定在农民的呼吸区，一个气泵固定在皮带上收集个人空气样本。XAD-2树脂中收集的农药用丙酮提取，离心，氮气排污浓缩，用1ml超纯水/ hplc级甲醇溶液3:1重组。采用超高效液相色谱-串联质谱（UHPLC-MS/MS）对提取物进行分析。检测到的目标化合物最高浓度可达462.5 ng m(-3)（氟虫腈）。危害商（HQ）小于1，危害指数（HI）为3.86 × 10(-3)，说明农药相关疾病风险不显著。pymetrozine的终生癌症风险（LCR）为4.10 × 10(-8)，处于可接受水平（LCR < 10(-6)）。本研究报告的结果在农业社区的风险管理方面是有益的。(C) 2017 Elsevier B.V.版权所有
Tanjung Karang, Selangor, is widely known for its paddy cultivation activity and hosts the third largest paddy field in Malaysia. Pesticides contamination in agriculture fields has become an unavoidable problem, as pesticides are used to increase paddy productivity and reduce plant disease. Human exposure to agrichemicals is common and could results in both acute and chronic health effects, such as acute and chronic neurotoxicity. This study aims to determine the concentrations of commonly used pesticides (azoxystrobin, buprofezin, chlorantraniliprole, difenoconazole, fipronil, imidacloprid, isoprothiolane, pretilachlor, propiconazole, pymetrozine, tebuconazole, tricyclazole, and trifloxystrobin) in personal air samples and their associated health risks among paddy farmers. Eighty-three farmers from Tangjung Karang, Selangor were involved in this study. A solid sorbent tube was attached to the farmer's breathing zone with a clip, and an air pump was fastened to the belt to collect personal air samples. Pesticides collected in the XAD-2 resin were extracted with acetone, centrifuged, concentrated via nitrogen blowdown and reconstituted with 1 mL of 3:1 ultrapure water/HPLC-grade methanol solution. The extract was analyzed using ultra-high-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). The target compounds were detected with a maximum concentration reaching up to 462.5 ng m(-3) (fipronil). The hazard quotient (HQ) was less than 1 and the hazard index (HI) value was 3.86 x 10(-3), indicating that the risk of pesticides related diseases was not significant. The lifetime cancer risk (LCR) for pymetrozine was at an acceptable level (LCR < 10(-6)) with 4.10 x 10(-8). The results reported in this study can be beneficial in terms of risk management within the agricultural community. (C) 2017 Elsevier B.V. All rights reserved.
