Screening for pesticide residues in soil and crop samples in Egypt

Abstract

Pesticide application is an important issue in intensive agricultural production to achieve self-sufficiency in food production. This study aimed to the determination of pesticide residues from soil samples cultivated with different crops. Forty soil samples from four governorates, ten samples each (Kafr El-Sheikh, El-Beheira, Giza, and Menoufia) were collected for pesticides multi-residual analysis. Also, fifteen vegetable samples were collected from Giza governorate and analyzed for the presence of pesticide residues. Obtained data revealed that soil samples of Giza governorate recorded the highest level of pesticide residues contamination with 70% positive samples followed by Kafr El-Sheikh and Menoufia governorates with 60% positive samples and finally El-Beheira governorate recorded the lowest level of pesticide residues contamination with 30% positive samples. Regarding the levels of pesticide residues in vegetables and crops, about 53.3 % of tested samples (onion, sweet potato, molokhia, cabbage, beet, okra, eggplant, and lettuce) were free from pesticide residues. Meanwhile, about 46.7 % of tested samples (wheat, rocca, green dill, tomato, radish, pepper, and green parsley) showed pesticide residues with different types and concentrations. Propiconazole was the highest residue recorded in green dill with 3.8 mg/kg followed by difenoconazole with 3.22 mg/Kg present in green parsley.

Pesticide Residues and Associated Public Health Risks in Vegetables from Irrigated Farms Adjacent to Rift Valley Lake Ziway, Ethiopia

“…In this particular study, the highest concentration of α-endosulfan recorded was similar to the fndings of Sheikh et al [37] in tomato samples from the Pakistani Sindh market, where the values ranged from null to 0.68 mg/kg. Te average concentration of this study is also consistent with the results of Essumang et al [38] from Ghana (0.3 mg/kg) and Mahugija et al [39] from Tanzania (0.3 mg/kg). However, the current fnding was higher than the results of López-Dávila et al [40] (0.01 mg/kg) from Cuba, Oyeyiola et al [41] (0.0016 mg/kg) from Nigeria, and Loha et al [13] (0.006 mg/kg) from Ethiopia.…”

Influence of the use of remediated soil and agricultural drainage water on the safety of tomato fruits

“…This enrichment was observed alongside higher concentrations of Cd in tomatoes produced in areas with elevated PTE concentrations compared to those from other regions in Spain (Enamorado Báez et al 2009 ; Abril et al 2008 ). However, the most severe source of contamination has become the use of contaminated agricultural drainage water for irrigation (Shehata et al 2019 ; Salem et al 2021 ). There is no doubt that vast areas of vegetable crops are now irrigated with raw agricultural drainage water in Egypt; such a practice led to the harvest of vegetable fruits being chemically and microbiologically contaminated, which for sure harms consumers’ health.…”

Acetamiprid exposure causes molecular and structural changes in the liver and kidney tissues of rats

“…However, direct exposure is primarily reported in pesticide manufacturing units and farm workers. 4,5 As per estimation by the World Health Organisation, nearly 3 million people suffer due to direct pesticide exposures, of which nearly 18000 succumb to death every year in developing countries emphasizing the problem of pesticide poisoning. 6 Acetamiprid (ACMP) is a systemic chlorinated neonicotinoid pesticide.…”
