Data on the effect of temperature and trace metal exposure on early life stages of European flat oysters and Pacific oysters@en

Data collection of concentration dependent abnormal larval development of Crassostrea gigas during 24 h at 24°C and 48 h at 18°C for the trace metals copper (Cu), zinc (Zn), Cadmium (Cd) and lead (Pb). Data were collected via microscopic observation. Data collection of concentration dependent mortality within a 24 h period at 18°C and 24°C for the D- larvae stage of Ostrea edulis and C. gigas for Cu, Zn, Cd and Pb. Data were collected via microscopic observation. All data were collected from February to April 2024 at IFREMER Bouin (La plateforme mollusques marins de Bouin) in France. Data includes the measured environmental concentrations (MEC) of the summer Cu concentration in the German Bight from 1986 to 2021 (MUDAB database, https://geoportal.bafg.de/MUDABAnwendung/), including sampling points coordinates, year of sampling and Cu concentration. Additionally the Hazard quotient (HQ) is provided by dividing the MEC with the predicted no effect concentration (PNEC), defined as EC10 estimates from C. gigas embryos exposed for 48 h at 18°C and LC10 estimates from C. gigas larvae exposed for 24 h at 24°C, divided by an assessment factor (AF) of 5.
