Abstract
The study was conducted to assess the level of contamination of marine fish persistent chemicals such as many Organophosphorus pesticide residues, where most countries suffer from the problems of pollution of marine fish persistent chemicals which have negative effects on human and animal health as cause of cancer, kidney failure, liver and fetal abnormalities as a result of accumulation in adipose tissue. However, the persistence of high levels of these pollutants with seafood is unknown accurately enough. And the aim of this study is to estimate Organophosphorus pesticide residues in Libyan fish where they were pulling samples of fish during the month (September, October, and November, 2013) from the local market to market the fish Port of Tripoli Sea, which is the main source of samples fresh. Samples were representative of the types of fatty fish include Round Sardinella (Sardinella aurita), European Pilchard (Thunnus thynnus), Madeiran Sardinella (Sardinella maderensis), Chub Mackerel (Scomber japonicus), Atlantic Mackerel (Scomber scombrus), Herring (Clupea harengus), and half of fatty fish include Roving Grey Mullet (Liza carinata), Flathead Grey Mullet (Mugil cephalus),Thicklip Grey Mullet (Chelon labrosus), Boxlip Mullet (Cdeachilus labeo), Albacore (Thunnus alalunya), Bluefin Tuna (Thunnus thynnus), Yellow Fin Tuna (Thunnus albacares) and Bogue (Boops boops). Dimethoate, Disulfaton, Famphur, Methyl parathion, O,O,O-Triethyl phosphoro thioate, Parathion and Phorate were detected in fish tissues and fat samples at level below the maximum residue limits (MRL). The results showed that there was no concentrations higher than the maximum residue limits, according to FAO and WHO, global in all tissues of the fish, which were estimated by Organophosphorus pesticides as for estimating vehicle Organophosphorus fats in fish has been found that some types of sardines and Grey Mullet contain high concentrations of Dimethoate (4.7611±0.02 , 1.1741±0.05) respectively, and some types of Tuna contain a high concentration of Famphur (1.0627±0.03), these concentrations are higher than the maximum residue limits, according to FAO and WHO where concentrations were calculated in mg / kg (µg/g , ppm) BW of fish.
