The utilization of organochlorine pesticides for pest control chemical has been of great interest on residue contamination from biological organisms in the environment. Green mussel (Perna viridis) samples were monitored as bioindicators for assessment of the water quality in coastal waters along the Gulf of Thailand. Thirty-six samples were collected from 12 stations during 1997-1999 and analy...
background: pesticides are essential in modern agricultural practices but due to their biocide activity and potential risk to the consumer, the control of pesticide residues in foods is a growing source of concern for the general population. extensive application of such agents as organochlorine pesticides in farmlands and contemporary agricultural industries has led to undesired environmental ...
background: the presence of organochlorine pesticides in the environment is a serious threat to human health and requires continuous monitoring. therefore, in the present systematic review, the residual amount of different organochlorine pesticides in human samples has been investigated. methods: all accessible databases in english and farsi were searched by using organochlorine and related p...
Residues of organochlorine pesticides were determined in soils and drinking water sources in cocoa growing areas in Ghana. Soil samples analysed showed the presence of four organochlorine pesticide residues namely lindane (0.005-0.05 mg/kg), beta-HCH (<0.01-0.05 mg/kg), dieldrin (0.005-0.02 mg/kg), and p,p'-DDT (0.005-0.04 mg/kg), with dieldrin occurring most frequently. Similarly, organochlori...
In this study, a new clean up method was developed for the routine multiresidue determination of organochlorine pesticide residues in honey. The analytical procedure requires sample extraction with methanol, followed by a clean up step through a C18 Sep-Pak cartridge. Finally, pesticides are eluted with hexane. The determination of organochlorine pesticide residues was performed by capillary ga...
Pesticides are a group of chemicals made for the purpose of killing or otherwise deterring “pest” species. The word pesticide may refer to insecticides, herbicides, fungicides, or other pest control formulations. Pesticides are inherently toxic and often associated with adverse health effects in non-target organisms.1 Organochlorine pesticides are a large class of multipurpose chlorinated hydro...
Study on The Use of QuEChERS Method for Analysis of Organochlorine Pesticides Residues in Cow's Milk
QuEChERS stands for (Quick, Easy, Cheap, Effective, Rugged and Safe) and pronounced as (catchers) is a method that had been developed for multi-pesticide residue analyses in food. This study was conducted to investigate the efficacy of QuEChERS method for analyzing the organochlorine pesticides residues in cow's milk. Twenty organochlorine pesticide namely (Benzene, 1,3,5-trichloro, Tetrachloro...
BACKGROUND Ambient levels of pesticides ("pesticide drift") are detectable at residences near agricultural field sites. OBJECTIVE Our goal was to evaluate the hypothesis that maternal residence near agricultural pesticide applications during key periods of gestation could be associated with the development of autism spectrum disorders (ASD) in children. METHODS We identified 465 children wi...
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...
Current Opinion in Pediatrics 2008, 20:191–197 Purpose of review This review summarizes the recent research on pesticide exposure and child neurobehavioral development with a focus on in-utero exposure to organochlorine and organophosphate pesticides. Recent findings Recent studies on in-utero exposure to the organochlorine pesticide dichlorodiphenyltrichloroethane and its breakdown product, di...
