Estuarine transmission of heavy metal pollutants - pilot study of the River Tees

Hydraulics Research (HR) has been engaged in field studies of the estuarine transmission of heavy metal pollutants to determine to what extent metals entering an estuary from an outfall or freshwater source are retained within the estuarine sediments and how much (if any) passes out to sea. This report outlines the methods of sample collection and analysis, presents and comments on the results and assess the suitability of the Tees estuary as an area for further investigation in HR's research program into estuarine transmission of heavy metal pollutants.
