Contamination of soils with heavy metals (HM) is widespread and poses a long-term risk to ground water quality and ecosystem health. Anionic surfac-tants, which are widely used in the detergent industry, may complex metals and thus modify the fate and transport of HM in soil. Anionic surfactants reach the soil water system from different sources, such as pesticides formu-lations and irrigation with wastewater, which is becoming a common agricul-tural practice in regions with scarce water resources. Anionic surfactants in wastewater originate mainly from detergents, being the most abundant or-ganic chemicals in municipal greywater (Abu-Zreig et al., 2003). Risk as-sessments and environmental regulations for polluted soils should take into account the mobility of HM in soils. In this study, we used batch extractions, to asses the effect of thee anionic surfactants on the mobility of Cd, Cu, Pb and Zn. Consecutive extractions were carried out as these can help evaluat-ing continuous addition of surfactant to the soil.
