摘要

在肯尼亚，水果和蔬菜种植中农药的广泛使用引起了人们对包括番茄水果在内的农产品中农药残留的担忧。尽管由于对人类和其他动物有有害影响而在欧洲被禁止使用，但仍有许多高度危险的农药，包括代森锰锌、草甘膦、毒死蜱、甲胺磷和氯氰菊酯等，在肯尼亚仍在使用。本研究旨在评价肯尼亚莱基皮亚县当地生产的番茄中氯氰菊酯农药残留水平。此外，该研究还发现了一些导致番茄农药残留水平的做法。采用QuEChERS法对82份番茄样品进行农药残留分析，采用气相色谱-质谱（GC-MS）法对合成拟除虫菊酯（顺式和反式-高效氯氰菊酯）农药进行分析。

Analysis of alpha-cypermethrin pesticide residues along the value chain of tomato from Laikipia County, Kenya

In Kenya, the extensive use of agrochemicals in fruits and vegetable farming raises concerns about pesticide residues in agricultural products including tomato fruits. There are still a number of highly hazardous pesticides including mancozeb, glyphosate acid, chlorpyrifos, acephate and cypermethrin amongst many others that are still used in Kenya despite being banned in Europe due to harmful effects on humans and other animals. This study aimed to evaluate the residual levels of cypermethrin pesticide in locally produced tomato in Laikipia County, Kenya. Also, the study identified some practices that lead to pesticide residual levels in tomatoes. A total of 82 tomato samples were analyzed for pesticide residues following extraction using QuEChERS method and analyzed for the presence of synthetic pyrethroids (cis- and trans-alpha-cypermethrins) pesticides using gas chromatography–mass spectrometry (GC–MS).
