- ABSTRACT Vegetables are a commodity that is needed as a source of nutrition for humans. Vegetables are broadly a source of fiber, vitamins and minerals that are good enough for the body and efficacious to improve health and metabolism. The vegetable plants are very susceptible to pests and diseases, farmers to control pests and diseases use pesticides. Organophosphate class pesticides are increasingly used for vegetable crops because of their beneficial properties for farmers. Organophosphate pesticides are selective, not persistent in the soil, and does not cause resistance to insects, works as contact poisons, stomach poisons and also respiratory poisons. Improper use of pesticides can lead to pesticide residues, as a result vegetables are often contaminated by pesticide residues. Pesticide residues contained in vegetables can have a direct or indirect impact on consumers. Organophosphate pescides by inhibiting the activity of cholinesterase enzymes, so that acetylcholine is not hydrolyzed. The possible effects on humans are bloody or runny nose, coughing, chest pain, shortness of breath and difficulty or wheezing due to narrowing or excess fluid in the bronchial tube. This study aims to determine the content of pesticide residues in various types of vegetables in the city of Bogor, West Java. The research method was carried out by taking cabbage, potato and carrot vegetables in several vegetable sellers in traditional and supermarket markets in the city of Bogor, West Java. Vegetable samples as much as ± 10 g were extracted using the QuEChERS method. The results of extracts were identified as organophosphate residues using Gas Chromatography (GC).The results of the study showed that some vegetable sample (cabbage, potato, and carrots) contained pesticide residues, i.e. chlorpyrifos, profenofos and diazinon. Chlorpyrifos pesticide residue concentrations of 0.0041-0.0295 μg/kg, profenofos 0.0018-0.0222 μg/kg and diazinon 0.0033-0.0144 μg/kg. This value is still below the pesticide BMR threshold value based on SNI 7313 in 2008.
