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...

OBJECTIVE In addition to water contamination, the presence of pesticide residues in food poses a risk to the population, being a serious public health problem in Brazil. With the purpose of getting a better understanding of this scenario, the use of pesticides in tomato crops in the State of Pernambuco, Brazil, was studied. METHODS Questionnaires were applied to obtain social and environmenta...

Quantitative measurements of environmental factors greatly improve the quality of epidemiologic studies but can pose challenges because of the presence of upper or lower detection limits or interfering compounds, which do not allow for precise measured values. We consider the regression of an environmental measurement (dependent variable) on several covariates (independent variables). Various s...

A convenient, quick and cost-effective method to detect the presence of allergenic components and pathogens is one of the greatest challenges confronting the food processing industry. Biosensors are emerging as a highly promising tool for rapid diagnosis of pathogens and allergenic components in foods. Detection of contaminants, verification of product contents, product freshness and monitoring...

The usage and acceptability of biological control methods are set to increase in agriculture in the future because of food safety and pesticide residue issues. Biological control implementation in Turkey started with control of cottony cushion scale Icerya purchasi (Homoptera: Margarodidae) through the introduction and release of Rodolia cardinalis (Coleoptera: Coccinellidae) in citrus plantati...

Three patients with aplastic anaemia had a history of substantial previous exposure to organochlorine pesticides. The temporal association between chemical exposure and the onset of first symptoms of anaemia was strongly supportive. Organochlorines have the property of lipid affinity and accumulation in adipose tissue. Objective evidence of clinically important concentrations of tissue pesticid...
