In this study, photocatalytic degradation of diazinon was investigated using commercial nano-TiO2as a photocatalyst the operational parameters such as adsorption, aeration, pH and nano-TiO2 dosage were investigated. Dispersive liquid-liquid microextraction (DLLME) technique was used to extract and preconcentration of residual diazinon and by-products from the liquid samples and the analysis was...

BACKGROUND Humans are ubiquitously exposed to multiple environmental contaminants. Consequences of combined action on the reproductive system remain unknown. This study aimed to assess single and joint effects of cadmium and diazinon exposure on sperm quality parameters. METHODS Male adult Wistar rats were randomized into 4 groups of ten animals each. Group A was used as a control, animals fr...

introduction: diazinon is a moderately toxic broad-spectrum organophosphate, with a ld50 of 350 to 400 mg/kg for humans. diazinon is absorbed through the skin and gastrointestinal tract and is rapidly metabolized within a few hours. diazinon residues in melons and cucumbers have recently became a major health concern in iran. thus we decided to investigate diazinon levels in melon and cucumbers...

background diazinon is one of the most widely used organophosphrous pesticides in the world may affect animals and human. objectives this study was done to assess whether pseudomonas plecoglossicida can grow on diazinon as the sole carbon metabolic source in laboratory and agricultural soil. materials and methods serial dilutions of pure and commercial diazinon in minimal salt medium were made ...

From October 2000 to April 2001, insecticide bioassays were conducted in 18 ranches from 10 counties in the states of Mato Grosso and Mato Grosso do Sul, in Central Brazil. Horn flies from wild populations were exposed to diazinon-impregnated filter papers immediately after collection on cattle, and mortality was recorded after 2 h. A high susceptibility to diazinon was observed in all tested p...

Introduction: Diazinon is one of the most widely-used organophosphate pesticides in the world. This toxin enters the body in various ways and induces oxidative stress in various tissues. It has been proved that activation of unfolded protein response (UPR) under oxidative stress is a steady mechanism for maintaining cell function and survival. Therefore, the present study aimed to review the ef...

This research aims to evaluate the presence and distribution of pesticides in Babolrood River of Mazandaran Province in Iran. Mean diazinon levels in surface water ranged from 77.6 to 101.6 μg L(-1) with maximum level of 768.9 μg L(-1) and mean malathion levels ranged from 55.7 to 75.9 μg L(-1) with maximum level of 506.6 μg L(-1). The residues of malathion and diazinon pesticides in all of the...

Although organophosphorus pesticides (OP) share a common mode of action, there is increased awareness that they elicit a diverse range of gene expression responses. As yet however, there is no clear understanding of these responses and how they interact with ambient environmental conditions. In the present study, we investigated genome-wide gene expression profiles in the nematode Caenorhabditi...
