Levels of 237 pesticides were assessed in 1063 fruit and vegetable samples from 12 São Paulo markets spanning the period May 2015 to December 2022. The QuEChERS method was employed for extraction, followed by GC-MS/MS and LC-MS/MS analysis. Findings indicated that 30% of the samples contained residues below the Maximum Residue Limits (MRLs), while 6% exceeded these. Additionally, 23% exhibited excessive residues for their respective crops and 40% had no detectable residues. Health risk evaluation focused on tomatoes, cabbage and oranges, revealing exposure within 0.002-0.9% of the Acceptable Daily Intake (ADI), indicating no chronic risks. However, pyraclostrobin in orange presented a potential acute risk for adults (112%). These results underscore the necessity for continuous monitoring of pesticide residues in fruits and vegetables to safeguard consumer health, especially considering the significant levels of consumption.
对 2015 年 5 月至 2022 年 12 月期间来自 12 个圣保罗市场的 1063 个水果和蔬菜样本中的 237 种农药水平进行了评估。采用 QuEChERS 方法进行提取，然后进行 GC-MS/MS 和 LC-MS/MS 分析。结果表明，30%的样本残留低于最大残留限量（MRLs），而 6%的样本残留超过了 MRLs。此外，23%的样本残留超过了各自作物的最大残留限量，40%的样本未检测到残留。健康风险评估集中在番茄、白菜和橙子上，结果表明摄入量在每日允许摄入量（ADI）的 0.002-0.9%范围内，表明不存在慢性风险。然而，橙子中的吡唑醚菌酯对成年人（112%）存在潜在的急性风险。这些结果强调了对水果和蔬菜中农药残留进行持续监测的必要性，以保障消费者健康，特别是考虑到其大量的食用量。
