2.4. Simulation Experiments for Contamination of the Soil with Malathion
Soil was contaminated with malathion under ambient atomspheric conditions, where 1000 g of the soil was mixed with a stock solution of malathion. This process was carried out by forming slurry followed by slow addition of malathion under continuous stirring. The soil was then dried, hand crushed and passed through the 2 mm sieve. Unused malathion was quantified as discussed below.
