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 an...

conclusions in conclusion, at measurement can be beneficial for the safety or recovery of malathion-induced toxic injury in liver tissue and liver mitochondria. results in liver tissue, the activity of lpo and cat was higher in the malathion group in comparison to controls. at reduced malathion-induced lpo, sod, cat, and gpx in rat liver. coadministration of at with malathion improved lpo, sod,...

Ground applied ultralow volume spraying is part ofthe integrated pest management program undertaken by the Saginaw County Mosquito Abatement Commission, and as such, is subject to scrutiny of its effectiveness in the program. For several years, the Commission relied almost exclusively on ultralow volume (ULV) malathion in the adulticiding program but always had problems effectively controlling ...

introduction: toxic effects of pesticides are commonly associated with reactive oxygen species damage and pentoxifylline a phosphodiesterase inhibitor is a drug well known for antioxidant properties. the purpose of this study was to evaluate the oxidative damages following a subacute exposure to malathion, an organophosphorus insecticide and pentoxifylline's ability to counteract these eff...

Effects of repeated pollutant exposure on growth, locomotor performance, and behavior have rarely been evaluated in reptiles. We administered three doses of malathion (2.0, 20, or 100mg/kg body weight) to western fence lizards (Sceloporus occidentalis) over an 81day period. Eight and 23% mortality occurred at 20 and 100mg/kg (p=0.079) and 85% of lizards in the 100mg/kg group exhibited clinical ...

INTRODUCTION The cholinergic nervous system and acetylcholine esterase are involved in chronic intoxication with organophosphorous insecticides. The present study aims to investigate the influence of the chronic toxicity of these chemicals on behaviors related to anxiety, using the elevated plus maze (EPM), in the male adult mouse. MATERIAL AND METHODS Either water or 1% concentration of mala...

Pesticides are used extensively in agricultural lands in Northern provinces of Iran which makes river ecosystems more vulnerable to pesticides pollution. This study was conducted in three river estuaries (Babolrud, Tajanrud and Gorganrud), focusing mainly on the concentration levels of organophosphate pesticides (diazinon, malathion, azinphos-methyl) in the muscle tissue of golden mullet fish, ...

Environmental chemicals may be involved in the etiology of breast cancers. Many studies have addressed the association between cancer in humans and agricultural pesticide exposure. Organophosphorous pesticides have been used extensively to control mosquito plagues. Parathion and malathion are organophosphorous pesticides extensively used to control a wide range of sucking and chewing pests of f...

The estimation of risk following exposure to mixtures is an important feature of pesticide risk assessment. Also of concern is the potential for increased sensitivity of the young to pesticide toxicity. We have conducted interaction studies using a mixture of five organophosphorus (OP) pesticides (chlorpyrifos, diazinon, dimethoate, acephate, and malathion) in both adult (published previously) ...

Chemical pesticides have an impact on other living organisms in addition to their intended target organisms. Any chemical pesticide is therefore made safe for use by examining its biological characteristics and side effects. The present study was aimed at determining the resistance efficiency of six bacterial isolates obtained from malathion-contaminated soils. Bacteria were isolated soil sampl...
