Study on Soil Mobility of Two Neonicotinoid Insecticides

Figure 3

Elution profiles of CLO and TMX upon absorption on soils. Concentrations of CLO (black columns) and TMX (grey columns) measured in aqueous eluates from soil columns of sand (a), clay (b), and loam (c) soils. Eluates from pumice columns (d) are shown as control. Concentrations in 10 mL fractions of the eluate are shown in μg/mL, as a function of the fraction number.
