Mean recoveries of pesticides a alachlor, b alpha-BHC, c chlorpyrifos, and d endrin ketone. Concentrations are represented as a percent of control treatment (t=0). No recovery is less than control (one-sided Dunnett’s test). Grey area highlights ±20% of control. Error bars represent 95% confidence intervals of the means (n=8 for t=0 control, and n=4 for all other treatments)
