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....

Malathion, when administered at noncholinergic doses, was previously shown to enhance the humoral immune response to a T-dependent antigen, sheep red blood cells (SRBC), and macrophage function. In addition, malathion was shown to cause mast cell degranulation. The hypothesis that mast cells contribute to the observed alterations in humoral immunity and macrophage function was determined by exa...

A total of 162 samples of different varieties of mango: Deshehari, Langra, Safeda in three growing stages (Pre-mature, Unripe and Ripe) were collected from Lucknow, India, and analyzed for the presence of seventeen organophosphate pesticide residues. The QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method of extraction coupled with gas chromatography was validated for pesticides an...

BACKGROUND Head-lice infestation is prevalent worldwide, especially in children 3 to 11 years old. Topical insecticides (i.e., pyrethroids and malathion) used as a lotion, applied twice at an interval of 7 to 11 days, are typically used for treatment. Resistance of lice to insecticides, particularly pyrethroids, results in treatment failure. The efficacy of alternative agents is controversial. ...

Susceptibility tests were conducted using the World Health Organization diagnostic test procedure on strains of Aedes taeniorhynchus, Aedes sollicitans, Aedes vexans, and Culex nigripalpus collected from several localities in Charleston and Georgetown counties of South Carolina. Aedes taeniorhynchus was resistant to malathion (mortality 1.0-54.4%) but not to propoxur, permethrin, or fenitrothio...

background: there is much evidence indicating that natural substances from edible and medicinal plants possess powerful antioxidant and hepatoprotective activities. the objective of the present study was to investigate the potential hepatoprotective effect of silymarin in fish exposed to malathion. methods: zebra cichlid fish were allocated into five groups of which one group received normal fe...

Stored unmilled rice (paddy), milled rice and maize treated with radiolabelled malathion formed bound 14C residues. After 3 months of storage, the bound residues in the grains treated with 10J.Lg/g malathion accounted for 10.8, 6.5 and 13.3% of the applied dose in paddy, rice and maize respectively. After 6 months, the corresponding values of bound residues were 14.2, 4 and 17.7% respectively. ...

Background: Pesticides are widely used in agriculture. Excessive use of pesticides has health risk for human and threatens non-target organisms. This research aimed to determine lethal concentrations of malathion and Hinosan for Carassius auratus (5±1 gr) [mean ± SD]. Methods: Experiments were performed according to O.E.C.D for 4 days (96 h) and concentrations of 0, 1, 2, 4, 8 mg L-1 Hinosan...

The pesticides are one of the most potentially harmful chemicals liberated in the environment in an unplanned manner Malathion is widely used as a potent pesticide in many countries and has been shown to produce some adverse health effects. A study was conducted to asses the effects of malathion on the male reproductive system of wistar rats. The pesticide was administered to rats orally at dos...
