Biomarkers of Biochemical and Cellular Stress in Carcinus maenas: and in situ Field Study

摘要

Biomarkers are useful diagnostic tools for identifying exposure to physical, chem- ical, and environmental stresses. In this study a suite of techniques-measure- ments of metallothionein, lysosomal integrity, and osmoregulatory ability-have been used in an attempt to provide an in situ assessment of environmental quality. Five estuarine sites were studied, two clean sites, two urban sites, and one inter- mediated. Shore crabs, Carcinus maenas, were collected and haemolymph taken for he lysosomal and osmoregulatory assays.
