We reported previously that insecticide exposures were widespread among minority women in New York City during pregnancy and that levels of the organophosphate chlorpyrifos in umbilical cord plasma were inversely associated with birth weight and length. Here we expand analyses to include additional insecticides (the organophosphate diazinon and the carbamate propoxur), a larger sample size (n =...

An experimental randomized controlled trial were used to assess in vitro and in vivo acaricidal effect of Diazinon against sheep lice Damalinia ovis on sheep kept under semi-intensive production system, in sheep farm of Adama University School of Agriculture, Asella campus, from November, 2011 to January, 2012. Thirty naturally infested sheep with D. ovis were purposely selected for the in-vivo...

This study was designed to investigate the acute toxic effect of Diazinon on some blood parameters. Twelve male rabbits were divided randomly and equally into two groups, A treated group (T) control (C). Animals dipped in 3:1000 diazinon solution. Within 24 hours following treatment, animals showed moderate symptom organophosphorous poisoning such as dyspnia depression. Blood analysis revealed ...

Imidacloprid (IMI) is at the moment the insecticide with the world's fastest growing sales and is considered possible replacement for the widely used organophosphorus pesticide, diazinon, which is subject to phased revocation in many countries. In this study, biochemical, reproductive and survival parameters of the water flea (Daphnia magna) after chronic exposure to IMI, its commercial liquid ...

Sorption and degradation are the primary processes controlling the efficacy and runoff contamination risk of agrochemicals. Considering the longevity of biochar in agroecosystems, biochar soil amendment must be carefully evaluated on the basis of the target agrochemical and soil types to achieve agricultural (minimum impact on efficacy) and environmental (minimum runoff contamination) benefits....

Acute toxic effects of three commonly used insecticidal preparations of the organophosphates chlorpyrifos, diazinon, and dichlorvos were examined in mixed breed broiler chicks, and cholinesterase activity in plasma and brain were measured. The acute (24 h) oral median lethal doses (LD50) of chlorpyrifos, diazinon, and dichlorvos were 10.79 mg kg(-1), 6.32 mg kg(-1), and 6.30 mg kg(-1), respecti...

The toxicity of a nutrient-pesticide mixture in nonvegetated and vegetated sections of a constructed wetland (882 m² each) was assessed using Hyalella azteca 48-h aqueous whole-effluent toxicity bioassays. Both sections were amended with a mixture of sodium nitrate, triple superphosphate, diazinon, and permethrin simulating storm-event agricultural runoff. Aqueous samples were collected at infl...

Rice striped stem borer is a cosmopolitan pest that widely distributed in different regions of northen Iran and spraying with diazinon is the most common procedure to control this pest. We evaluated comparative physiological effects of diazinon spraying on the three populations of Chilo suppresalis collected from Gourabzarmikh (Go), Sheikhmahale (Sh) and Rasht (Ra) in Iran. The determination of...

Diazinon is an organophosphate which is extensively used in trade and agriculture. Due to its widespread application, its toxicity is common. Several studies have shown that organophosphates are able to induce oxidative stress by generating free radicals and depletion of endogenous antioxidants. Pomegranate seed oil (PSO) possesses anti-inflammatory and antioxidant effects. In this study, the e...

BACKGROUND Regulatory decisions to phase-out the availability and use of common organophosphate pesticides among the general public were announced in 2000 and continued through 2004. Based on revised risk assessments, chlorpyrifos and diazinon were determined to pose unacceptable risks. To determine the impact of these decisions, organophosphate (OP) exposure incidents reported to the National ...
