UNLABELLED A gas chromatography mass spectrometry with spike calibration curve method was used to quantify three carbamate pesticides residue in cooked white rice and to estimate the reduction percentage of the cooking process duration. The selected pesticides are three carbamate pesticides including carbaryl and pirimicarb that their MRL is issued by "The Institute of Standards of Iran" and pr...
Pesticides are extensively world wide used for agriculture and for non-agricultural purposes. The major environmental concern of used pesticides is their ability to leach down to subsoil and contaminate the ground water, or, if they immobile, they could persist on the top soil and become harmful to microorganisms, plants, animal and people (Jha & Mishra 2005; Radivojević et al., 2008). Harmfull...
BACKGROUND Chemical analysis of surface water conducted in European countries indicates that pesticides are often detected in surface waters. This asks regulatory authorities to consider these monitoring data while re-evaluating pesticide approval and setting appropriate risk mitigation measures. During the years 2005-2012, the cantons in Switzerland performed 345,000 pesticide measurements in ...
The main goal of this study was to determine the levels of knowledge of the farmers on the effect of pesticides on environment in Dawadmi Province, Saudi Arabia. This is achieved through realizing some secondary objectives such as identification of the farmers' socioeconomic characteristics and its relation to some of the study variables, their attitude towards the negative effects of pesticide...
pesticide induced complications among pistachio farmers: in the rural area of rafsanjan, iran (2010)
background: pesticides have important effects on human health. due to the wide range of pesticide application and also involvement of more than 60% of people living in this study area in the agriculture, it is essential to assess the side effects of these biohazards. therefore, we designed this study to assess the impact of using pesticides on the health status of pistachio farmers, in rural ar...
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...
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...
Considerable amounts of organochlorine pesticides (DDT, lindane, heptachlor and methoxychlor) were detected in drinking water samples during a two-year study in Warka-Grojec rural region of Poland. The average incidence of drinking water sources with detectable levels of pesticides ranged from 20 to 30%. According to Polish regulations concerning water quality, individual concentrations did not...
The major pesticides of the world are glyphosate-based herbicides (GBH), and their toxicity is highly debated. To understand their mode of action, the comparative herbicidal and toxicological effects of glyphosate (G) alone and 14 of its formulations were studied in this work, as a model for pesticides. GBH are mixtures of water, with commonly 36-48% G claimed as the active principle. As with o...
With the establishment of the National Institutes of Biotechnology and Applied Microbiology (BIOTECH), University of the Philippines Los Baños (UPLB) researches were done to look for cheaper and locally available but efficient substitutes or supplements to inorganic fertilizer, such as bio-fertilizers and bio-pesticides. Technologies on bio-fertilizers developed by UPLB include BIO-N, the most ...
