Monitoring of Some Organophosphorus and Organochlorine Pesticides Residue in Beef Meat from Khartoum State Slaughterhouses | Biomedgrid

Background: Organochlorine and Organophosphorus Pesticides are found in the environment in small concentrations, but they have cumulative characteristics thus become a threat to human health and life. This study is focused on detection and determination of some of these pesticides in bovine muscles, meat in two main slaughterhouses in Khartoum state. Materials and methods: 50 samples were collected in sterile bags, transferred to the lab, samples were extracted within 24 hours of collection using mixture hexane and acetone, followed by partitioning and drying the samples using rotary evaporator at 40ºC. clean up step was achieved using silica gel column previously washed with hexane. Pesticides residues read against standards using GC-FID. Results: seventy-two percentage of samples obtained from slaughterhouse one was positive, while slaughterhouse two showed 87.5% positive samples. Ethiphane is the prevailing pesticide residue in samples obtained from both slaughterhouse facilities, it represented 61.1% and 80.9% respectively. The mean value of the detected levels was 0.147 and 0.27 ppm in order.
