dimethoate (organophosphate insecticide) and lambda-cyhalothrin (synthetic pyrithroid) aretwo frequently used pesticides due to their high effectiveness and rapid breakdown into environmentally safeproducts. the aim of this present study was to assess and compare the acute toxicity of dimethoate(rogor30%ec) and lambda-cyhalothrin (5%ec) on labeo rohita (hamilton). acute toxicity bioassay wascar...

Residues of Dimethoate present in locally available Spinach varities Palak : Beta maritima, Vendhai : Trigonella foenumgraecum, Thandan : Amarnathus mangostanus green and red were determined. The quantification was carried out using RP-HPLC for unprocessed (fresh) and processed (washed, washed and cooked) Spinach samples. The extraction was carried out with benzene. It was found that unprocesse...

Possible adverse effect

Multiple environmental factors acting in concert can interact and strongly influence population fitness and ecosystem composition. Studies investigating interactions usually involve only two environmental factors; most frequently a chemical and another abiotic factor such as a stressful temperature. Here we investigate the effects of three environmental factors: temperature, an insecticide (dim...

Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, enzyme essential for central nervous system function. Dimethoate insecticide can be used both indoor and outdoor purposes to eliminate a number of insect pests under different condition. Dimethoate, one the most extensively studied pesticides, may induce many significant changes in fishes...

Although the pesticides are widely used in agriculture, they, and in particular the relative residues in foodstuff, waters and atmosphere, make a remarkable social alarm and sanitary problems for the harmful effects (carcinogenic and mutagenic effects) producing on the human health. In fact, their spread in waters and atmosphere can produce undesired effects on various organisms and determine t...

Seventy-three fungal species belonging to forty-three genera were isolated from 40 samples of Saccharrum officinarum (collected from Naage-Hamadi canal in Qena Governorate, Egypt). Aspergillus, Trichoderma, Mucor and Pythium were the most common genera on the two isolation media. The dominant species of Aspergillus were A. niger, A. flavus, A. ustus, A. terreus and A. wentii. Some species were ...

Toxicity of copper (Cu) and two biodegradable chemicalsÐan insecticide (dimethoate) and a detergent (LAS), was tested on a common forest litter invertebrate carnivore Lithobius mutabilis and its prey, Musca domestica. The chemicals were mixed into arti®cial food medium for house ̄y larvae, and the centipedes were kept on contaminated OECD soil and fed contaminated larvae. The concentrations of c...
