Determination of pesticide residues above and below MRL in selected vegetable of south Punjab, Pakistan

Abstract

The increased production of food goods to satisfy the requirements of the people has led to the widespread use of pesticides. It is important to note that the use of these pesticides poses a risk of contaminating both the land and the food supply. The present study was carried out to determine selected pesticides namely Imidacloprid, Chlorpyrifos, Cypermetrin and Lufeuron residual in vegetables (Tomato, Okra, Cabbage, Cauliflower, Green Pepper, Carrot, Radish and Bottle Gourd) collected from fields and shops in villages and commercial market of south Punjab. The four districts of south Punjab were selected for sample collection. The names of selected districts were Khanewal, Multan, Muzaffargarh and Vehari. These samples were prepared and subjected to high pressure liquid Chromatography (HPLC) for detection of pesticide residues. The results showed that around 48 percent of vegetable samples have high MRL, 32 percent of vegetable samples have low MRL and 20 percent of vegetable samples show no results. Pesticides are used to control illnesses and pests, despite the fact that they are utilized. However, pesticide residues are still present in vegetables, which have the potential to cause consumers to experience adverse health effects. Because of this, it is strongly advised that continual monitoring of pesticide residues be carried out.
