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...

In this study, it was aimed to determine organochlorine pesticides (OCPs) in three types of milk (cow's, buffalo's, and sheep's milk) produced in Afyonkarahisar province of Turkey. The results indicated that these milk specimens were found to be contaminated by 21 different pesticides. Sixteen OCP residues were detected in sheep's milk and it was followed with 14 pesticides in buffalo's milk an...

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 ...

Food safety has a direct impact on human health and as such is a growing concern worldwide. Presence of harmful pesticide residue in food is a serious cause for concern among consumers so it is important to monitor levels of pesticides in foods. The aim of this study was simultaneous determination of concentrations of 58 pesticides in 40 wheat flour samples collected from Tehran market in Janua...

The aim of present study was to assess pesticide residues in vegetables in the Pathanamthittadistrict.The concentrations of six pesticides were determined by gas chromatography coupled with mass selective detector (GC-MS) in locally produced vegetables purchased from wholesale markets. A total of 20 samples of four vegetables viz. Pea, snakegaurd, bittergaurd,brinjalwereanalyzed for pesticide r...

Cabbage (Brassicaceae) is one of the most frequently consumed exotic vegetables in Benin and also the most affected by insects. To meet growing food demand, farmers rely heavily on synthetic pesticides that are harmful for themselves, consumers and the environment. Integrated pest management has been proposed as the means to improve vegetable productivity and quality in many developing countrie...

3. The Codex principles of risk analysis, particularly those for risk assessment, are primarily intended to apply to discrete chemical entities such as food additives and pesticide residues, or a specific chemical or microbial contaminant that have identifiable hazards and risks; they are not intended to apply to whole foods as such. Indeed, few foods have been assessed scientifically in a mann...

An efficient, rapid, and selective method for sample pretreatment, namely, molecularly imprinted matrix solid-phase dispersion (MI-MSPD) coupled with gas chromatography (GC), was developed for the rapid isolation of four phosphorothioate organophosphorus pesticides (tolclofos-methyl, phoxim, chlorpyrifos, and parathion-methyl) from carrot and yacon samples. New molecularly imprinted polymer nan...
