PYR Metabolites BaP Metabolites Cell Viability Phagocytosis Antioxidant Status The length of spokes for PYR and BaP metabolitesindi-cate the levels of these contaminants found in the urine of shore crabs at each site in each season.
The spokes for cell viability, phagocytosis and antioxi-dant status give an indication of physiological health. The Avon represents good health while the length of spokes for the Yealm and Plym denote the percentage difference in value from the Avon.
