Table 2.
Growth rates of different benthic foraminifera species when exposed to additions of Cu, Cd, Zn, and Hg. Criteria maximum concentrations (CMC) were calculated based on the source published data according to the screening quick reference tables (SQuiRTs) of National Oceanic and Atmospheric Administration (NOAA) [41]. Growth rates were modified based on the source published data.
