Background and Objective: Farmers in agricultural activities deal with various forms of chemical pesticides and thus their knowledge level can have a positive or negative impact on the food health of a community and the environment. Understanding their knowledge about the consequences of poisoning will provide an effective extension for promoting environmentally friendly methods in farms and ma...
considering the increasing rice consumption in the world and also the excessive application of pesticides to increase production, an experiment was conducted to determine the pesticide residues and their effects on nitrogen, potassium and phosphorus content of hashemi, khazar and gohar (sa13) rice cultivars, in a factorial design at randomized complete block design with three replications. in t...
A reliable, rapid and accurate method based on spiked calibration curves and direct sample introduction was developed for determination of 17 pesticide residues in rice by gas chromatography-mass spectrometry single quadrupole selected ion monitoring GC/MS-SQ-SIM. Sample preparation is based on extraction with acetonitrile without clean up. The use of spiked calibration curves for constructing...
In communities which consume rice as main food, importance of risk assessment forcontaminants is always taken into consideration by health authorities. The present study isan attempt for monitoring of 56 pesticides from different chemical groups in rice samplescollected from local markets in Tehran and estimation of daily intake of interested pesticidesthrough this monitoring. A valid method ba...
For the first time, a multi-residue methodfor simultaneous determination of 41LC-amenable pesticides in rice, belonging to different chemical classes has been developed in Iran by LC-MS/MS. The pesticides were analyzed simultaneously in a single run using positive electrospray ionization with multiple reaction monitoring (MRM) after extraction with slightly modified QuEChERS method. The calibra...
background improper use of pesticides has become a serious in regard to human health in recent years. overlooking safety regulations, using pesticides creates many problems and health hazards for people. objectives this paper aimed to investigate the use of pesticides by pistachio farmers in kerman, iran. materials and methods this study was conducted in chatroud county, kerman province, iran. ...
In recent years, water pollution and pesticide residues in the food chain have become a serious environmental and health hazard problem. Therefore, an efficient technology is essential for complete mineralization of pesticides to non-toxic forms. Nanotechnology offers many potential benefits to improve existing environmental technologies using new materials with effective performance, re...
