Determination of Pesticide Residue in Water and Soil Collected from Water-harvesting Ponds Haffirs, Gedarif State, Eastern Sudan

Abstract

The study was conducted in 2017 and 2018 at Elgadarif State Sudan in Azaza, Trafa and Elkafey affairs soils. The main objective of this study was to determine the levels of pesticide residue in water and soil Collected from Water-harvesting Ponds (Haffirs), Gedarif State, Eastern Sudan. Water samples (48) and (36) soil samples were collected randomly from each reservoir. Each sample was divided into glass bottles and plastic, a water sample in a dark (brown) bottle and a soil sample in a dry place to analyze pesticide residues. Organochlorine pesticides (OCPs) in water were investigated by Trafa, Azzaza, and Elkafey Haffir in 2016. The study indicated total concentrations of organochlorine pesticide residues (Lindane) in different parts of water and soil from July, September, November, and January, respectively. In Azaza haffirs water, the levels of the pesticides in the water sample were 81%, 73%, 60% and 71%, respectively. Presents the mean area percentages of Organochlorine pesticide residues (Lindane) in different parts of water and soil from July, September, November and January, respectively. In Azaza haffirs water, the levels of the pesticides in the water sample were 81%, 73%, 60% and 71%, respectively. The lowest area percentages of 60% were observed in November, while the highest area percentage of 81% was observed in July. It was not detected in the Trafa and Elkafey haffirs water, and all soil haffirs were not detected in any of the samples. The results showed that the percentage of carbaryl (1-Naphthanol) in soil was high in Azaza (85.41%), and Tarfa (86.78) haffirs and increased significantly (P≤ 0.05), while in Elkafey haffirs was low 56.58%. However, the pH values in the different Haffir water and soil were within the recommended level used for pH (6.5-8.4). The present study investigated the pesticide residues, namely Lindane, through the most sophisticated technique (GCMS). Lindane also has long-term effects on human health, including weeds. Pesticides are used in public health to kill disease vectors, such as mosquitoes, anaemia and liver, testicular, bone marrow, and kidney damage HMR.
