The Toxicity of Copper to Pacific Oyster and Sea Squirt from Japan Using Regional Seawater as a Test Medium
Copper (Cu) toxicity is an increasing concern in marine environments; however, its effects are species- and area-specific. In this study, area-specific Cu toxicity test was conducted on the sensitive early life stages (i.e., embryonic and larval development) of two important fisheries species, namel...

Copper (Cu) toxicity is an increasing concern in marine environments; however, its effects are species- and area-specific.

Measured concentrations for C. gigas and nominal concentrations for H. roretzi were used to calculate effect concentrations for each species. The 10% effect concentration (EC10) for Cu were 12.8–17.0 and 15.0–22.0 µg L−1, and 50% effect concentration (EC50) for Cu were 20.3–22.6 and 45.6–47.2 µg L−1, respectively.
