In present study the photocatalytic degradation of the organophosphorus pesticide fenthion, under UV irradiation in the presence of titanium dioxide (TiO2) photocatalyst, in aqueous suspensions has been investigated and compared with the photodegradation by hydrogen peroxide (H2O2) solution as an oxidant agent. The experiments were carried out in a 250mL pyrex UV laboratory-constructed photorea...
The use of filter soil is increasing for control of quality of stormwater runoff prior to infiltration or discharge. This study aimed to gain knowledge about treatment efficacy of filter soils at field scale. Percolate samples from swale-trench systems with filter soil based on agricultural till with/without limestone were monitored for 15 and 9 rain events respectively. Further, two curb exten...
Four diazinon-degrading bacteria were isolated from agricultural soil by using an enrichment technique. The biochemical analysis and molecular method including RFLP indicated that these isolates were identical, and one strain designated DI101 was selected for further study. Phylogenetic analysis based on 16S rDNA sequencing indicated that the strain DI101 clearly belongs to the Serratia marcesc...
Pesticide Action Network, United Farmworkers of America, and California Rural Legal Assistance Foundation analyzed California government data on agricultural poisonings and enforcement of worker safety standards. Nearly 500 pesticide poisonings were reported for California farmworkers every year from 1997 to 2000. The actual number of pesticide-related illnesses is unknown, since many poisoning...
To evaluate quantitative and qualitative traits as well as thrips resistance of onion genotypes, an experiment was conducted at Behbahan Agricultural Research Station, Behbahan, Khuzestan, Iran from 2013 to 2015. The experiment was a split plot based on a randomized complete block design with three replications. Pesticide-treated and pesticide-free plots were considered as sub plots and ten oni...
BACKGROUND Pesticide poisoning is an important cause of morbidity and mortality in India. OBJECTIVES To assess the oxidative damage, hemoglobin level and leukocyte count in acute organophosphorus pesticide poisoning. METHODS Plasma cholinesterase was assessed as a toxicity marker. Oxidative damage was assessed by estimating serum malondialdehyde (MDA) levels, plasma total antioxidant capaci...
OBJECTIVE Despite the rapid industrialisation and urbanisation over the past 30 years, agriculture is one of the largest economic sectors in China and the unregulated use of pesticides result in extensive pesticide poisoning. The objective of this study was to analyse pesticide poisoning cases registration received by Zhejiang Provincial Center for Disease Control and Prevention, China. DESIG...

The objective of this study was to analyse pesticide poisoning cases regi...
CONTEXT Pesticides continue to be used on school property, and some schools are at risk of pesticide drift exposure from neighboring farms, which leads to pesticide exposure among students and school employees. However, information on the magnitude of illnesses and risk factors associated with these pesticide exposures is not available. OBJECTIVE To estimate the magnitude of and associated ri...
