Solar photocatalytic mineralization of commercial pesticides: Oxamyl

Solar Energy Materials and Solar Cells, 2000
Abstract One of the most important sources of high-pesticide-content polluted waters results from the rinsing of pesticide containers. In this paper, a pre-industrial solar TiO 2 -photocatalytic treatment is used to prevent such pollution of continental waters and a commercial pesticide (Vydate L®, 24% oxamyl) is used as a model to demonstrate the ...

Phototransformation of oxamyl in aqueous solution

Environmental Chemistry Letters, 2008
The photolysis of the N methyl carbamate pesticide oxamyl (Z isomer) has been studied in aqueous solution. Continuous irradiation at mainly λ = 254 and λ > 290 nm has been performed to characterise the pesticide photochemical behaviour in water at pH = 6.0.

Wildlife toxicity studies with oxamyl

Environmental Toxicology and Chemistry, 1982
AbstractThe acute oral LD50 of oxamyl in bobwhite (Colinus virginianus), mallards (Anas platyrhnchos) and Japanese quail (Coturnix c. japonica) is 9.4, 2.6 and 4.3 mg/kg BW, respectively. The eight-day dietary LC50 in bobwhite and mallards is 54 and 369 ppm, respectively.

Bioremediation of oxamyl in sandy soil using animal manures

International Biodeterioration and Biodegradation, 2009
Abstract The bioremediation of the nematicide oxamyl, applied at the recommended rate of 6 l ha −1 in sandy soil cultivated with tomato and amended with different animal manures at the recommended dose of 2.5 tons ha −1 , was investigated. The experiment was conducted in a controlled environmental chamber under a 16-h photoperiod, with a light ...

Distribution and persistence of oxamyl in oxamyl-treated seed potatoes and in plants grown from oxamyl-treated seed potatoes

Journal of Agricultural and Food Chemistry, 1990
A direct linear relationship between oxamyl concentration of treatment solutions and oxamyl deposit on soaked potato seed tubers (cv. Russett Burbank) was observed. Increasing the duration of soaking from 1 to 40 min had no effects on oxamyl deposit. No decrease in the oxamyl concentration of the treatment solutions was observed after the tubers were ...

Acute Toxic Effects of Oxamyl in the Rat

Toxicological Sciences, 1992
The effects of single acute oral doses of 1, 2.1, and 3.5 mg/kg oxamyl (a carbamate insecticide) on selected biochemical parameters in male Sprague-Dawley rats were investigated. The animals exhibited significantly decreased weight gain when compared to control animals.

Adsorption of oxamyl on montmorillonites

Australian Journal of Chemistry, 1978
The adsorption of oxamyl under variable conditions of time, pH and exchangeable cations on montmorillonites has been examined. Kinetic studies showed the reaction to be first order, which indicates diffusion-controlled adsorption. All the evidence obtained by studies of the effect of pH, adsorption isotherms, considerations of the chemical structure of

Acute toxicity studies with oxamyl

Fundamental and Applied Toxicology, 1986
The acute toxicity of oxamyl, an insecticide and nematicide, has been evaluated to establish proper handling guides. The material is highly toxic when given as a single oral dose; its LD50 is in fasted rats 2.5 to 3.1 mg/kg, 2.3 to 3.3 mg/kg in fasted mice, and 7 mg/kg in guinea pigs. A beagle dog given 30 mg/kg died, while 15 mg/kg was not lethal.

Metabolism of oxamyl in mice and twospotted spider mites

Archives of Environmental Contamination and Toxicology, 1979
The metabolic fate of oxamyl was examined in mice and twospotted spider mites,Tetranychus urticae Koch. Mice treated intraperitoneally with oxamyl-14C eliminated 96.4% of the dose in the urine (88.7%) and feces (7.7%) by 96 hr; 75.7% of the dose was eliminated during the initial 6 hr. Organosoluble urinary radioactive material ranged from 24.6% at 6 hr
