The use of a metallothionein-like-proteins (MTLP) kinetic approach for metal bioavailability monitoring in dredged material.

Ecotoxicological effects associated with contaminants present in dredged material from Spain were determined using a marine biotest based on the determination of metallothionein-like-protein concentrations (MTLPs) in the shore crab Carcinus maenas. Intermoult female C. maenas were exposed in the laboratory to sediments from three Spanish ports, Ría de Huelva (SW, Spain), La Coruña (NW, Spain) and Bahía de Cádiz (SW, Spain) per replicate during 21 days.
