The homogeneity of analytical samples and the stability of pesticides during the sample processing of oranges and tomatoes were evaluated. The mean concentrations of 14C-labeled chlorpyrifos in analytical portions (subsamples) after processing show that homogeneity is dependent on sample type as well as the processing procedure. The homogeneity of analytical samples of tomatoes processed cryoge...

Abstract: The impact of pesticide residues on human health is a worldwide problem, as human exposure to pesticides can occur through ingestion, inhalation, and dermal contact. Regulatory jurisdictions have promulgated the standard values for pesticides in residential soil, air, drinking water, and agricultural commodity for years. Until now, more than 19,400 pesticide soil regulatory guidance v...

Between September 1995 and September 1996, 4-day composite duplicate plate samples (379 solid food samples and 303 beverage samples) were obtained from a stratified random sample of 75 individuals in Maryland and analyzed for the presence of 10 pesticides. Samples were collected in each of six approximately equally spaced cycles as part of a larger pilot investigation of longitudinal exposure t...

An analysis of pesticide residue data was performed to describe and quantify differences between organically grown and non-organic fresh fruits and vegetables. Data on residues in foods from three different market categories (conventionally grown, integrated pest management (IPM)-grown/no detectable residues (NDR), and organically grown) were compared using data from three test programmes: The ...

This study focused on studies of pesticide residues in organic product. With increasing health and environmental awareness, organic farming has become an integral part of the agricultural policy in many countries. It is the less harmful to human and environment. The target of organic farm is not high quantity of production, but is the high quality. The market value of organic products in Europa...

"The man has no divine right over the food. He must compete for this with weeds, diseases, insects and other organisms” (Grodner, 1996). With the above quote, Grodner clearly reflects the situation in the area production and processing of food. More than 10.000 species of insects and mites, 1.500 species of fungi and 600 plant species have been identified as harmful to agriculture (Grodner, 199...

due to the uncensored use of pesticides in the agricultural regions of lebanon, the contaminationrisks of drinking water by organic residues increase periodically in planting seasons. no previous work havebeen considered in north lebanon plain concerning pesticide pollution though it is the second agriculturalzone in lebanon with an excessive activity. in this context, the aim of this study was...
