BACKGROUND Since organophosphorus pesticides are widely used for industry and insect control in agricultural crops, their fate in the environment is very important. Pesticide contamination of surface water has been recognized as a major contaminant in world because of their potential toxicity towards human and animals. The objective of this research was to investigate the influence of various p...

Wild bee communities provide underappreciated but critical agricultural pollination services. Given predicted global shortages in pollination services, managing agroecosystems to support thriving wild bee communities is, therefore, central to ensuring sustainable food production. Benefits of natural (including semi-natural) habitat for wild bee abundance and diversity on farms are well document...

The pesticide policy arena is filled with discussion of probabilistic approaches to assess ecological risk, however, similar discussions about implementing formal probabilistic methods in pesticide risk decision making are less common. An influence diagram approach is proposed for ecological risk-based decisions about pesticide usage. Aside from technical data, pesticide risk management relies ...

We describe a lethal poisoning in a healthy woman caused by deliberate ingestion of aluminium phosphide (AlP), a pesticide used to kill rodents and insects. Toxicity of AlP and review of cases reported to the National Poisons Information Service (London) 1997-2003 are discussed.

We are reporting a case of poisoning with a non-organophosphate pesticide (indoxacarb) resulting in methemoglobinemia and seizures, and successfully treated with ventilator care and intravenous ascorbic acid. Since there are limited data concerning the human toxicity of indoxacarb, physicians in emergency rooms should be aware of this rare poison and also its clinical presentations.

Mass mortality among migratory birds at Grand Forks, North Dakota, was attributed to a mosquito control operation employing the insecticide fenthion. The factors involved may have included the toxicity of the pesticide for birds, the method of application and coincidence with the peak of the spring warbler migration.

This study was carried out to determine the pesticide residue levels and health risk assessments in tomato, pepper, cucumber grown Tokat province of Turkey. A analytical method verified 260 pesticides by using a liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pesticide solutions at 10 50 µg kg­¹ doses were fortified with pesticide-free matrix for verification method. The linearities ...

background: diazinon is an organophosphate pesticide which is widely used in paddy fields located in northern parts of iran, though it is prohibited to be used in many countries. objectives: the purpose of the present study was to investigate sublethal effects of diazinon on blood parameters of common bream abramis brama. methods: in sublethal toxicity test, fish were exposed to diazinon concen...

— This paper uses a large database of laboratory test results to investigate the sources of international variation in pesticide residues on food products. We specify and estimate a model that incorporates contamination effects attributable to product pest sensitivity, pesticide toxicity levels and characteristics of the producing country. Among the latter, our model tests for the effects of in...

Information on the health impacts of pesticides is quite limited in many developing countries, with many surveys relying solely on farmer self-assessments of their health status. To test the reliability of self-reported data, an acetyl cholinesterase enzyme (AChE) blood test was conducted for 190 rice farmers in the Mekong Delta, Vietnam. Results reveal a high prevalence of pesticide poisoning ...
