Cefas already monitors dredged sediments from industrialised estuaries for poisonous metals. Such areas are regularly dredged to maintain harbour entrances, and the excess material is tested for toxicity.
In the laboratory, burrowing crustaceans that normally graze on the surface of sediment were placed in a tank with dredged material from one of these sites. The creatures were then exposed to current sea conditions as well as acid levels predicted for the next 50 and 10
