Zinc in freshwater and marine water
Zinc is an essential trace element required by many aquatic organisms. Zinc toxicity is hardness–dependent (also alkalinity) and a hardness algorithm is available (Table 3.4.3 of the ANZECC & ARMCANZ 2000 guidelines). Toxicity decreases with increasing hardness and alkalinity (Holcombe & Andrew 1978, Mount 1986).
