Web30. mar 2010 · In almost all pesticide leaching experiments (e.g. lysimeters, fields), the soil surface is quite level (no meso- and macro-depressions). In the computer simulations, the soil surface is nearly always assumed to be level. A common assumption in the evaluations is that water flow and substance transport in soil are rather uniform. Webthe soil compartment is that this is the compartment of concern with regard to persistence. The persistence of an active substance is the integrated effect or weighted summation of … WebIt is concluded that, in the context of ecotoxicological risk assessments for surface water, MACRO can give reasonably good simulations of pesticide concentrations in water draining from cracking clay soils, but that prior calibration against hydrologic and tracer data is desirable to reduce uncertainty and improve accuracy. round fish bowls illegal
