Abstract
A method for the extraction of organochlorine (OC) residues from rainwater has been developed using coated polyurethane foam. The efficiency of the extraction procedure has been tested at low concentrations (sub-ng l−1) and the effects of flow rate, pH, suspended particulates and the volume of water analyzed have been determined. The coated foam plugs were incorporated into eight sampling units stationed along the eastern coastline of the United Kingdom to monitor the atmospheric deposition of organochlorines. The results obtained have been used to predict the annual contribution of OCs from the British mainland deposited into the North Sea.
