biochars produced from woodchips and cotton
straw pyrolyzed at 850 C resulted in a remarkable decrease in
the dissipation of chlorpyrifos, carbofuran, and fipronil from soil
due to their high sorption, which consequently reduced their bioavailability.
Those authors also reported a pronounced decrease
in the uptake of these pesticides by the plants grown in contaminated
soils. Comparatively less efficiency was reported by the biochar
produced at
