  • Pesticides and the Environment MU Extension

    Leaching Leaching is the movement of pesticides through the soil rather than over the surface. Leaching depends in part on the pesticide s chemical and physical properties. For example a pesticide held strongly to soil particles by adsorption is less likely to leach. Another factor is solubility.

     · The leaching adsorption ability of As(III) by ferrihydrite is minimized at pH 3.0. The reason is that pH 3.0 is a strongly acidic environment relative to other pH levels leading to the partial dissolution and severe reduction of the amount of iron mineral and resulting in the reduction of adsorption ability.

  • Sorption and leaching behavior of bithionol and levamisole

     · The batch experiments were conducted to understand sorption process of bithionol (BIT) in yellow soil (YS) and red soil (RS) while column leaching experiments were performed to evaluate the leaching behavior of BIT and levamisole (LEV) in the tested soils. The adsorption and desorption data fitted well with the Freundlich isotherms (R2 ≥ 0.94).
