Residues of plant protection products can be nowadays found in almost all samples of fruits as even if their application was carried out with respect to standards of Good Agricultural Practice. The intake of these compounds with food of plant origin may result in various disorders and diseases. Since the use of plant protection agents seems unavoidable, it is necessary to treat contaminated foo...

The growing public concern about groundwater contamination, pesticide residues, soil erosion, and wildlife habitat runs parallel to “an emerging interest by many farmers for a more costeffective and environmentally benign agriculture” (USDA, 1990). But only a small number of farmers are using alternative farming systems (Board of Agriculture, 1989). The cause of the limited adoption of sustaina...

Measuring river water concentrations of all pesticides applied in a catchment area is a daunting task. This study aims to develop new score tables for selecting analytical target pesticides. Sensitivity analyses were conducted using a diffuse pollution hydrologic model to quantitatively evaluate the influence of pesticide properties (e.g., log K(OC), degradability [half-life]) on concentrations...

Pesticides and other chemicals often have detrimental effects at environmental concentrations. Many amphibian species are particularly threatened because of their susceptibility but also because wetlands are often polluted. Behavioral assessments of toxicity have the advantage of showing sublethal effects but quantitative measures at varied scales of integrations are rarely considered together....

CONTEXT There is little evidence linking adverse reproductive effects to exposure to specific pesticides during pregnancy. CASE PRESENTATION In February 2005, three infants with congenital anomalies were identified in Collier County, Florida, who were born within 8 weeks of one another and whose mothers worked for the same tomato grower. The mothers worked on the grower's Florida farms in 200...

Environmental fate and transport assessments are an integral part of the pesticide registration process. These assessments include an evaluation of the pesticide’s potential to impact ground or surface waters using data from field studies. While properly designed field experiments provide a relatively high degree of confidence in predicting pesticide fate under particular experimental condition...

background: there are inconsistencies about the effects of farmworker housing and workplace conditions and use of self-protective behavior practices and personal protective equipment (ppe). objective: to investigate the association between workplace and housing conditions and farmworker use of pesticide safety practices and ppe. methods: this study was conducted in 4 counties in north carolina,...

background: organic agricultural pesticides are so stable in ecosystems and biosphere. these compounds affect soil conditions and agricultural products. the aim of this study was isolation of diazinon-degrading bacteria from kerman pistachio orchards, southeastern iran. methods: diazinon-degrading bacteria were enriched in bushnell-hass medium. identification and sequencing of prevalent degradi...

Assessing climate change impacts on pesticide leaching requires careful consideration of different sources of uncertainty. We investigated the uncertainty related to climate scenario input and its importance relative to parameter uncertainty of the pesticide leaching model. The pesticide fate model MACRO was calibrated against a comprehensive one-year field data set for a well-structured clay s...

BACKGROUND A wide range of pesticides is applied for crop protection in vegetable cultivation in China. Regulation of pesticide maximum residue limits (MRLs) in vegetables is established but not fully enforced. And pesticide residues in vegetables were not well monitored. This study conducted the monitoring surveys from 2011 to 2013 to investigate the pesticides in vegetables in the northwest r...
