متن کاملpersistence of benthiocarb in soil: influence of ultraviolet and sunlight
persistence of benthiocarb in soil as affected by uv and sunlight exposure was studied. treated soil was placed in petri plate, brought to field capacity moisture and then exposed to uv and sunlight. residues of benthiocarb in soil dissipated with half lives of 2.10, 11.85 and 43.63 days under uv, sunlight and dark condition, respectively. soil samples kept under dark showed the slowest dissipa...
متن کاملBioremediation of Herbicide-Contaminated Soil and Water
The contamination of soils, groundwater and surface waters by herbicides poses major clean-up problems. At present, the most common approach is containment, involving costly removal of highly contaminated soils to landfill sites. Bioremediation methods for in situ treatment are needed as alternative and/or supplementary approaches for cost-effective and residue-free clean-up. This project focus...
متن کاملFluid Extraction of Fluometuron Herbicide from Soil
Soil was treated with "C-ring-labeled fluometuron [N,N-dimethyl-N'[3-(trifluoromethyl)phenyll urea] (0.516 and 5.16 pmol gl), air-dried, and stored for 6 months at 5 "C. The 14C was then extracted from soil with methanol by conventional extraction (twice with MeOH/H20 8020 v/v; 2:l extract/soil v/w) and with CO2 using a supercritical fluid extractor. Supercritical fluid extraction (SFE) method ...
متن کاملMeasuring herbicide volatilization from bare soil.
A field experiment was conducted to measure surface dissipation and volatilization of the herbicide triallate after application to bare soil using micrometeorological, chamber, and soil-loss methods. The volatilization rate was measured continuously for 6.5 days and the range in the daily peak values for the integrated horizontal flux method was from 32.4 (day 5) to 235.2 g ha(-1) d(-1) (day 1)...
