摘要
These data show that of the three major constituents characteristic of most hard waters (i.e., Ca2+, Mg2+, and the CO2 system) calcium ion, introduced either as sulfate or carbonate, is the major source of protection against cadmium toxicity. This protective effect is observed in the absence of significant cadmium precipitation. Magnesium ion, sulfate ion, sodium ion and the carbonate system provide little or no protection. © 1979 Springer-Verlag New York Inc.
