The Bacillus licheniformis strain isolated from the intestine of Labeo rohita by an enrichment technique showed capability of utilizing dimethoate as the sole source of carbon. The bacterium rapidly utilized dimethoate beyond 0.6 mg/mL and showed prolific growth in a mineral salts medium containing 0.45 mg/mL dimethoate. The isolated B licheniformis exhibited high level of tolerance of dimethoa...

Residue levels of dimethoate and its oxon metabolite (omethoate) during tea planting, manufacturing, and brewing were investigated using a modified QuEChERS sample preparation and gas chromatography. Dissipation of dimethoate and its metabolite in tea plantation followed the first-order kinetic with a half-life of 1.08-1.27 d. Tea manufacturing has positive effects on dimethoate dissipation. Pr...

The pesticides are one of the most potentially harmful chemicals liberated in the environment in an unplanned manner. Dimethoate is widely used as a potent pesticide in many countries and has been shown to produce some adverse health effects. In the present study, we investigated the effect of dimethoate (an organophosphate insecticide) on the reproductive system and fertility of male rats and ...

II. THE USE OF SELECTED BIOMARKERS, PHAGOCYTIC AND CHOLINESTERASE ACTIVITIES, TO DETECT THE EFFECTS OF DIMETHOATE ON MARINE MUSSEL (Mytilus edulis) 2.1.. Abstract Effects of organophosphorous pesticide, dimethoate on blue mussels, Mytilus edulis using selected biomarkers have been studied. Mussels were exposed to serial dilutions of dimethoate, 7.88, 15.75, 31.35 and 63.00 μg/l including positi...

OBJECTIVE To determine the efficiency of selenium and/or vitamin E to alleviate lung oxidative damage induced by dimethoate, an organophosphorus compound. METHODS Adult Wistar rats were exposed during 30 days either to dimethoate (0.2 g/L of drinking water), dimethoate+selenium (0.5 mg/kg of diet), dimethoate+vitamin E (100 mg/kg of diet), or dimethoate+selenium+vitamin E. RESULTS Exposure ...

Application to the soil of the insecticide dimethoate had no effect on the growth of soybean colonized by the arbuscular mycorrhizal (AM) fungus Glomus mosseae and by the indigenous AM fungus. The application of the recommended concentration of dimethoate decreased the percentage of colonization of soybean by the indigenous AM population, but no significant effect was observed on the colonizati...

Dimethoate is among the most used organophosphorus ( OP ) in agriculture and public health pest control. The compound was classified as a moderately toxic to mammals and accidental poisoning in human is very common. The objective of the present work was to further evaluate dimethoate acute toxicity as well as its effects on body weight change and some blood parameters of male and female swiss a...

The present investigation was directed to study the possible protective activity of quercetin-a natural antioxidant against dimethoate-induced cyto- and genotoxicity in meristematic cells of Allium sativum. So far there is no report on the biological properties of quercetin in plant test systems. Chromosome breaks, multipolar anaphase, stick chromosome, and mitotic activity were undertaken in t...

The effect of dimethoate on the photosynthetic activity and pigments content on Cajanus cajan L. is determined by laser induced chlorophyll fluorescence (LICF) and fluorescence induction kinetics (FIK) of leaves. The LICF spectra is recorded in the region of 650-780 nm by using 405 nm violet diode laser and FIK curves are recorded at 685 and 730 nm by using 635 nm red diode laser as the excitat...

Organophosphorus (OP) insecticide self-poisoning is responsible for about one-quarter of global suicides. Treatment focuses on the fact that OP compounds inhibit acetylcholinesterase (AChE); however, AChE-reactivating drugs do not benefit poisoned humans. We therefore studied the role of solvent coformulants in OP toxicity in a novel minipig model of agricultural OP poisoning. Gottingen minipig...
