an extraction method based on matrix solid phase dispersion (mspd) and high performance liquid chromatography with uv detection for quantification of two widely used pesticides (malathion and α-endosulfan) in khazar rice from north of iran were investigated. the ratio of solid phase (adsorbent) to sample, types of eluting solvent and its volume were optimized to achieve the highest recoveries f...

A simple and efficient method for simultaneous gas chromatographic (GC) determination of 18 organochlorine pesticides [tecnazene, hexachlorobenzene, alpha-benzenehexachloride (BHC), pentachloronitrobenzene (PCNB), gamma-BHC, heptachlor, aldrin, methyl pentachlorophenyl sulfide, beta-BHC, delta-BHC, heptachlor epoxide, alpha-endosulfan, trans-chlorodane, cis-chlorodane, p,p'-dichlorodiphenyl dic...

Available information on organochlorines and the chronic effects of exposure to them are set out. Organochlorinated compounds are the most persistent pesticides and can be found in all ecosystems. Although they are generally efficient in pest control, they are also a potent environment pollutant and can provoke health problems in man. The evidences of the carcinogenic potential of organochlorin...

Abstract Background: poisoning is one of the most common medical emergencies. Every year many people refer to emergency wards due to poisoning and some of them are treated and some die because of severe complications. Most patients who refer to emergency wards are those who commit intentionally to suicide. This study is conducted to determine the prevalence of poisoning with pesticide (organop...

Accumulation of organochlorine compounds is well studied in aquatic food chains whereas little information is available from terrestrial food chains. This study presents data of organochlorine levels in tissue and plasma samples of 15 critically endangered Iberian lynx (Lynx pardinus) and other 55 wild carnivores belonging to five species from three natural areas of Spain (Doñana National Park,...
