Abstract

Pesticides are used in vegetable farming to control pests and diseases, reduce crop losses and improve yield. The study examined pesticide residues in irrigation waters and leafy green vegetables grown in some farming areas in Accra, Ghana. Three types of irrigation water sources (n = 23) and two exotic and four indigenous Ghanaian leafy vegetables (n = 34) from 10 farming areas in Accra, Ghana were collected and examined for 15 organochlorines, 13 organophosphorus and 9 synthetic pyrethroids pesticide residues using the modified QuEChERS procedure. Pesticide residues were detected on 50% (17/34) of the leafy vegetable and 52% (12/23) of the irrigation water samples analysed. Chlorpyrifos and deltamethrin were the most detected pesticide residues in the vegetables and irrigation water. About 26.5% of the vegetables contained pesticide residues exceeding the EU maximum residue limits, so vegetable farmers should be encouraged to comply with appropriate measures on pesticide use to enhance food safety.

加纳阿克拉绿叶蔬菜和灌溉水中的农药残留。

蔬菜种植中使用农药来控制病虫害、减少作物损失和提高产量。这项研究考察了加纳阿克拉一些农业区灌溉水和种植的绿叶蔬菜中的农药残留情况。研究收集了加纳阿克拉 10 个农业区的 3 种灌溉水源（n = 23）和 2 种外来及 4 种本地加纳绿叶蔬菜（n = 34），并使用改良的 QuEChERS 程序检测了 15 种有机氯、13 种有机磷和 9 种合成拟除虫菊酯农药残留。在分析的叶菜和灌溉水样本中，分别有 50%（17/34）和 52%（12/23）的样本检测到农药残留。毒死蜱和溴氰菊酯是蔬菜和灌溉水中检测到的最多的农药残留。约 26.5%的蔬菜所含的农药残留量超过欧盟规定的最高残留限量，因此应鼓励菜农遵守适当的农药使用措施，以提高食品安全。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
