Occurrence of Residual Organophosphorus Pesticides in soil of some Asian countries, Australia and Nigeria

Abstract

Abstract The aim of this systematic review study was to provide a precise estimation and awareness of the remaining organophosphorus pesticides in global soil and sediments. To do so, both international and national databases of PubMed, Scopus and the Institute for Scientific Information, Scientific Information Database, Iranmedex and Magiran scientific were searched/used to find studies published from 1968 to 2017. Next, the following keywords in English and Persian were used including: “organophosphorous” or “organo-phosphorous” or “organophosphate” with or without “pesticide” or “toxicity”; “soil” or “topsoil”. Based on our systematic search, a total number of 15 articles were chosen and used to analysis. Most studies have been conducted in Asian countries and some part of Africa and commonly used organophosphorous pesticides included chloroprifous, dichlorvos, diazinon, fenitrothion, malathion and profenofos. On the other hand, personal interviews showed that chloroprifous, dicrotophos and profenofos are more used widely in the world. Random effects model to estimate the overall amounts of the residue organophosphorus pesticides in global soil was used. Accordingly, the overall concentration of organophosphorus pesticides was estimated to be 131.05 mg/kg (95%CI, 130.98–131.12).
