Heavy metal concentrations (μg/g) in the tissue of the gastropod Agaronia razetoi (Ar) and bivalve Tivela tripla (Tt) from the sampling sites.

Sites	Cu	Mn	Zn	Cr
Site 1 (S1)^Ar	4.575 ± 1.33 a	bd	11.9 ± 3.42 a,b	0.35 ± 0.01 a
Site 2 (S2)^Ar	7.05 ± 0.25 a	bd	16.3 ± 1.30 a	0.28 ± 0.06 a
Site 3 (S3)^Tt	4 ± 0.73 a	bd	3.15 ± 0.93 b	0.32 ± 0.03 a

The values shown are mean ± SE (with n = 4, 2, 4) from S1, S2, and S3, respectively. bd, below detection limit.
