BACKGROUND Fruit and vegetables have health and nutritional value, but can also be a source of toxic contaminants such as pesticide residues. OBJECTIVE The aim of this study was to evaluate presence of pesticide residues in fruit and vegetable crops from the central and eastern region of Poland in order to check the compliance of these products with the maximum residue levels' (MRLs) requirem...

Chlorpyrifos is a broad spectrum moderately toxic organophosphorous insecticide. It is widely used in agriculture for pest control and in households as a termicide. However, exposure to chlorpyrifos and its metabolites can affect the public health resulting from its long residual periods in soil and water. Thus, there is an essential need to develop sensitive method for the detection of chlorpy...

This paper deals with the analysis of pesticide residues by chromatographic methods in samples of plant origin. Emphasis is put on the isolation and clean-up steps of the sample preparation for GC or LC determination. The problems of the extraction solvent selection and clean-up procedures using different types of adsorption column chromatography or gel permeation chromatography are discussed. ...

Chemical contaminants in food have caused serious health issues in both humans and animals. Microarray technology is an advanced technique suitable for the analysis of chemical contaminates. In particular, immuno-microarray approach is one of the most promising methods for chemical contaminants analysis. The use of microarrays for the analysis of chemical contaminants is the subject of this rev...

Food security and safety are the major concern in ever expanding human population on the planet earth. Each and every year insect pests cause a serious damage in agricultural field that cost billions of dollars annually to farmers. The loss in term of productivity and high cost of chemical pesticides enhance the production cost. Irrespective use of chemical pesticides (such as Benzene hexachlor...

Environmental pollution by pesticide residues is a major environmental concern due to the extensive use of these substances in agriculture. The insecticide beta-cyfluthrin is a synthetic pyrethroid widely used in agricultural and other domestic activities. The aim of the present study was to assess the genotoxic effects of a sublethal exposure of the fish Bryconamericus iheringii (Characidae) t...

Loose particles on impervious surfaces are an important carrier to transfer pesticides into residential runoff water and subsequently contribute to contamination of urban streams and estuaries by urban-use pesticides. However, data regarding levels of pesticide contamination in the runoff-transferable dusts are scarce and their runoff potential and toxicity impacts to urban watersheds still rem...

Twenty one kinds of direct competitive ELISA test kits were developed for checking insecticides and fungicides. The pesticides are applied just before harvests. Low molecular compounds including pesticides do not have an antibody by producibility themselves. However, some of them produce antibody by binding covalently to the surface of immunogenics protein to innoculate. These compounds are cal...

This investigation was undertaken to test different control strategies against Botrytis cinerea vineyards. Two commercial vineyards, "Barbera" and "Moscato," located in Piedmont (Northern Italy) were divided into seven plots and treated with different combinations of fungicides including fenhexamid, pyrimethanil, fludioxonil + cyprodinil, iprodione, and boscalid, a new carboxamide compound. An ...
