The mineralization of 14Clabeled methyl parathion in a soil from a semiarid Mediterranean area was followed by a simple method This method consisted in trapping evolved CO2 in a NaOH trap using common laboratory glassware and low quantities of reagents Volatiles were trapped in polyurethane foams which are cheap and easy to handle The influence of soil water content 10–20 and the addition of surfactants Aerosol 22 and hexadecyl trimethyl ammonium bromide HD and metals Cu and Zn were assessed Different models were applied to evaluate parathion mineralization kinetics Mineralization kinetics was initially faster for 20 soil water content although the final mineralization extent was similar in the range of tested soil water content Surfactants behaved differently HD decreased mineralization rate while Aerosol 22 did not affect parathion mineralization A bimetal Cu and Zn solution led to a significant decrease in methyl parathion mineralization which persisted when applied together with HD Results suggest a possible reduction of pesticide availability in soil or a direct effect of the exogenous chemicals on soil microbial community
