The effect of the pyrethroid, bifenthrin, on rainbow trout (Oncorhynchus mykiss) was assessed based on biochemical, haematological and histopathological examination of fish exposed to Talstar 10 EC pesticide preparation (active substance 100 g/l bifenthrin) at a concentration of 14.7 μg/l. There was a significant (P < 0.01) decrease in plasma ammonia, and significant (P < 0.01) increase in gluc...

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...

BACKGROUND Pesticide poisoning is an important health problem among Chinese farm workers, but there is a paucity of pesticide poisoning data from China. Using the WHO standard case definition of a possible acute pesticide poisoning, we investigated the prevalence and risk factors of acute work-related pesticide poisoning among farmers in Southern China. METHODS A stratified sample of 910 pest...

In this study, the levels of organochlorine (OC) pesticide residues in Lake Parishan have been investigated using water, sediment and fish (Barbus brachycephalus caspius) samples as a case study to find out the extent of pesticide contamination and accumulation in the lake. Six OC pesticides namely DDT, DDE, Lindane, Endosulfan, Heptachlor and Chlordane were analyzed in four sites at four seaso...

Pesticide applications to agricultural lands in California, USA, are reported to a central data base, while data on water and sediment quality are collected by a number of monitoring programs. Data from both sources are geo-referenced, allowing spatial analysis of relationships between pesticide application rates and the chemical and biological condition of water bodies. This study collected da...

The purpose of this article is to provide an overview of pesticide poisoning in South Korea and the relevant epidemiologic characteristics. During the period of 1996–2005, an approximate average of twenty-five hundred fatalities occurred per year due to pesticide poisoning, while age-standardized mortality rates by pesticide poisoning significantly increased from 4.42 to 6.42 per 100,000 popula...

Combined liquid chromatography-mass spectrometry using electrospray or atmospheric-pressure chemical ionization has become an important tool in the quantitative analysis of pesticide residues in various matrices in relation to environmental analysis, food safety, and biological exposure monitoring. One of the major problems in the quantitative analysis using LC-MS is that compound and matrix-de...

Although several cytogenetic biomonitoring studies on workers exposed to pesticides have been reported, there is only limited information on this topic from developing countries where pesticides have been widely used over the years. People in developing countries are at higher risk from exposure, due to poor working conditions and a lack of awareness of the potential hazards during manufacturin...

OBJECTIVE To investigate the effect of 3-year phased bans of the pesticides dimethoate and fenthion in 2008-2010, and paraquat in 2009-2011, on suicide mortality in Sri Lanka. METHODS Age-standardised overall, sex-specific, and method-specific suicide rates were calculated using Sri Lankan police data (1989-2015). Using negative binomial regression models, we estimated the change in the rate ...
