Applicability of polar organic compound integrative samplers for monitoring pesticides in groundwater

摘要: Polar organic chemical integrative samplers (POCISs) for the monitoring of polar pesticides in groundwater were tested on two sites order to evaluate their applicability by comparison with spot-sampling approach. This preliminary study shows that, as surface water, POCIS is a useful tool, especially screening substances at low concentration levels that are not detected laboratory analysis spot samples. For quantitative results, rough estimation obtained. The challenge now define required water-flow conditions relevant quantification and establish more representative sampling rates groundwater.
