ORGANOHALOGEN COMPOUNDS – Volume 66 (2004) 246 Introduction Pesticide residues in food present a potentially serious and significant cause for concern . Many pesticides have been associated with significant health effects to the nervous and endocrine systems and some have been deemed carcinogenic . There are many well-established techniques for pesticide analysis. However, commercial pesticide ...

We address the impacts of regulations designed to reduce pesticide poisoning of farmers and farm laborers. Attention is concentrated on pre-harvest interval regulations that impose a time interval between pesticide application and harvest. The incidence of poisoning is determined by aggregate pesticide use, worker exposure, and toxicity. A dynamic, stochastic model of insect population growth i...

Pesticides are widely used in Thailand, and can lead to serious acute and chronic health effects. To understand the determinants of pesticide exposure, such as farmers’ behaviors, is important in the effort to reduce exposure effectively. In this study, a standardized questionnaire was designed and used in order to collect information on use and safety behavior related to pesticide in chilli-gr...

BACKGROUND We evaluated the relationship between diagnosed depression and pesticide exposure using information from private pesticide applicators enrolled in the Agricultural Health Study between 1993 and 1997 in Iowa and North Carolina. METHODS There were 534 cases who self-reported a physician-diagnosed depression and 17,051 controls who reported never having been diagnosed with depression ...

Intensive residential use of insecticides has resulted in their ubiquitous presence as contaminants in urban surface streams. For pest eradication, urban hard surfaces such as concrete are often directly treated with pesticides, and wind/water can also carry pesticides onto hard surfaces from surrounding areas. This study expanded on previous bench-scale studies by considering pesticide runoff ...

Although macropore flow is recognized as an important process for the transport of pesticides through a wide range of soils, none of the existing spatially distributed methods for assessing the risk of pesticide leaching to groundwater account for this phenomenon. The present paper presents a spatially distributed modelling system for predicting pesticide losses to groundwater through micro- an...

Fish farming is increasingly dependent on plant commodities as a source of feed leading to an increased risk for pesticide residues in aquaculture diets and consequently their transfer into aquaculture food products. The European pesticide regulation requires fish metabolism and fish feeding studies where residues in fish feed exceed 0.1 mg kg(-1) of the total diet (dry weight basis) to enable ...

The evolution of resistance against pesticides is an important problem of modern agriculture. The high-dose/refuge strategy, which divides the landscape into treated and nontreated (refuge) patches, has proven effective at delaying resistance evolution. However, theoretical understanding is still incomplete, especially for combinations of limited dispersal and partially recessive resistance. We...
