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...

Biopurification systems, such as biofilters, are biotechnological tools to prevent point sources of pesticide pollution stemming from on-farm operations. For the purification processes pesticide sorption and mineralization and/or dissipation are essential and both largely depend on the type of filling materials and the pesticide in use. In this paper the mineralization and dissipation of three ...

The struggle against the agricultural ravagers was increased in few last years; many products were appeared and destined to kill the harmful insects, of which we did not know their effects on ecosystem and non-target animals. In present work, we try to investigate the ecotoxicological effects of Novaluron; an Insect growth Regulator (IGR) pesticide, on ecosystem and biomasses by the estimation ...

BACKGROUND Research suggests that independent and joint effects of genetic variability in the dopamine transporter (DAT) locus and pesticides may influence Parkinson's disease (PD) risk. MATERIALS METHODS In 324 incident PD patients and 334 population controls from our rural California case-control study, we genotyped rs2652510, rs2550956 (for the DAT 5' clades), and the 3' variable number...

Children are exposed to pesticides through a number of sources, including residential and agricultural applications. Parental occupational exposure to pesticides is also a concern because exposures occurring during pregnancy and carry-home residues also contribute to children's cumulative burden. A number of epidemiological studies consistently reported increased risks between pesticide exposur...

Probabilistic techniques were used to characterize dietary exposure of consumers to pesticides found in twelve commodities implicated as having the greatest potential for pesticide residue contamination by a United States-based environmental advocacy group. Estimates of exposures were derived for the ten most frequently detected pesticide residues on each of the twelve commodities based upon re...

BACKGROUND Many studies revealed toxic effects of pesticides on pesticide handlers but very fewer studies have been reported among grape garden pesticide sprayers in India. The purpose of this study was to evaluate the effect of pesticides among grape garden sprayers. METHODS 27 pesticide sprayers in study group and 27 non sprayers in control group were recruited. Blood samples were analyzed ...

Indicators are used to quantify the pressure of pesticides on the environment. Pesticide risk indicators typically require weighting environmental exposure by a no effect concentration. An indicator based on spread equivalents (ΣSeq) is used in environmental policy in Flanders (Belgium). The pesticide risk for aquatic life is estimated by weighting active ingredient usage by the ratio of their ...

background: the primary agricultural product in egypt is the cotton crop. children and adolescents work seasonally in the cotton fields applying pesticides. objectives: to examine the effect of pesticide exposure on clinical and biochemical parameters in children and adolescents applying pesticides. methods: male children currently applying pesticides and aged between 9 and 19 years (n = 50) we...

The Green Revolution, which brought together improved varieties, increased use off ertilizer, irrigation and synthetic pesticides, is credited with helping to feed the current global population of 6 billion. While this paper recognizes the ability of pesticide\, to reduce crop losses, it also discusses their potential negative effects on public health, with particular emphasis in developing cou...
