The federal laws and regulations governing the registration and use of pesticides in the United States under the Federal Insecticide, Fungicide, and Rodenticide Act are published in the Federal Register, while state laws such as California are published in the California Food and Agricultural Code, Divisions 6, 7, and 13. Up until the passage of the Food Quality Protection Act (FQPA of 1996), f...
We measured organophosphorus (OP) pesticide exposures of young children living in an agricultural community over an entire year and evaluated the impact of agricultural spraying on exposure. We also examined the roles of age, sex, parental occupation, and residential proximity to fields. We recruited 44 children (2-5 years old) through a Women, Infants, and Children clinic. We collected urine s...
BACKGROUND Pesticides and correlated lifestyle factors (e.g., exposure to well-water and farming) are repeatedly reported risk factors for Parkinson's disease (PD), but few family-based studies have examined these relationships. METHODS Using 319 cases and 296 relative and other controls, associations of direct pesticide application, well-water consumption, and farming residences/occupations ...
A method is developed for the determination of nine organophosphorus pesticide residues in cereals and kidney beans by capillary gas chromatography with flame-photometric detection. In this method, dichloromethane is used for clean-up after liquid-liquid extraction. It is shown that good separations are obtained using a fused-silica capillary column (DB-1701) by the optimized temperature progra...
The concept of using cholinesterase bioscavengers for prophylaxis against organophosphorous nerve agents and pesticides has progressed from the bench to clinical trial. However, the supply of the native human proteins is either limited (e.g., plasma-derived butyrylcholinesterase and erythrocytic acetylcholinesterase) or nonexisting (synaptic acetylcholinesterase). Here we identify a unique form...
The freshwater fish, Channa gachua was exposed to sub-lethal concentrations of an organophosphorus pesticide, monocrotophos. The fish was exposed to acute toxicity of monocrotophos for 16, 24 and 48 hours while for chronic toxicity it was exposed for 15, 30 and 45 days. The monocrotophos was found to be toxic to the fish, which was found to be increasing with the increase of its concentration. ...
BACKGROUND Acute organophosphorus pesticide poisoning (AOPP) is becoming a significant problem and a potential cause of human mortality because of the abuse of organophosphate compounds. This study aims to determine the independent prognostic factors of AOPP by using multivariate logistic regression analysis. METHODS The clinical data for 71 subjects with AOPP admitted to our hospital were re...
The evaluation of cereal-based product contamination by pesticide residues is a topic worldwide importance, and reliable analytical methods for official check analyses monitoring studies are required multi-residue analysis at trace levels. In this work, validated multi-residual method gas-chromatography tandem mass spectrometry coupled with rapid QuEChERS procedure was used the determination 37...
Received on 22 May and finalized on 21 June 2013. _____________________________________________________________________________ ABSTRACT Monocrotophos is the Asia’s most selling insecticide is a systemic and highly toxic organophosphorus pesticide that has been banned in many Countries and known to produce cholinergic and non-cholinergic effects. It listed as a Prior Informed Consent chemical, ...
