This increase
in numbers and viability seen at the lower concentration,
was explained by the fact that copper is an essential metal, and
from the concentration of 50 lM and upward the metal began to
become cytotoxic. However, by the results obtained here in this
work, the concentration of copper, which is much lower than those
used in the works above (for example, 500 lM copper chloride is equivalent to 67 lg/L) shows to be cytotoxic for anemones cells,
confirming that this cell type is sensitive to copper.
