Farmers’ pest management practices, awareness and their perception about the effects of pesticides’ use on the environment were discussed in this study. Data were collected from the vegetable farmers who operate along the banks of the rivers, streams and dams at the outskirts of the city. A purposive sampling technique was used to collect data from 128 vegetable farmers who use pesticides in ve...
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...
BACKGROUND Pesticides, including insecticides, herbicides and fungicides, are widely used in Australian agriculture. There is growing public concern about their impact on human health. OBJECTIVE This article reviews the available evidence about the potential chronic health effects of pesticides, particularly relating to children and breastfeeding women, and discusses the potential role of org...
Multi-Residue Analysis of Pesticides in Pistachio Using Gas Chromatography-Mass Spectrometry (GC/MS)
Background: Analysis of pesticide residues in food and other environmental commodities have become an essential requirement for consumers, producers, food inspectors and authorities. This study is focused on validation of an accurate, rapid and reliable method for multi-residual analysis of pesticides in pistachio as a strategic crop for export and one of the main nuts in Iranian food basket. M...
Tea is an agricultural product of the leaves, leaf buds, and internodes of various cultivars and sub-varieties of the Camellia sinensis plant, processed and vulcanized using various methods. Tea is a main beverage in Iranian food basket so should be free from toxic elements such as pesticides residue. There is no data bank on the residue of pesticides in the consumed black tea in Iran. The pres...
A method for the determination of 24 organochlorine pesticides by gas chromatography-mass spectrometry (GC-MS) with negative-ion chemical-ionization (NICI) using programmable temperature vaporizer (PTV)-based large volume injection (LVI) is described. The ion source temperature was determined to be 150 °C for the optimized NICI-selected ion monitoring (SIM) conditions. PTV inlet parameters were...
Hazardous substances including persistent, bio-accumulative and toxic substances (PBTs), are chemicals which do not degrade easily in the environment. They typically accumulate in fatty tissues and are slowly metabolized often resulting in increased concentration through the food chain. Pesticides have also been used for breeding animals mainly to protect them from infestation of pests. The mai...
DESIGN/METHODOLOGY/APPROACH This study presents literature reviews for the period 2000-2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures. FINDINGS This study indicates that the health literature has focused on individuals with...
A survey of pesticide residues in 316 baby foods on the Tokyo market from April 1999 to June 2005 was carried out. Fifteen kinds of pesticides, including organophosphorus, organochlorine, carbamate, pyrethroid and others, were detected between at levels Tr (below 0.01 ppm) and 0.55 ppm from 28 samples. The baby foods in which residual pesticides were detected were produced from flour, leaf vege...
The induced toxicity of three pesticides (alpha-Hexachlorocyclohexane: α-HCH; Parathion methyl:PM; Carbofuran: CN) in single and four possible combination on human keratinocyte cell line have been investigated. There was no significant change in toxicity (cyto and genotoxicity) on cell line exposed by individual pesticides except α-HCH. But, a synergistic effect was observed when we tested mixt...
