Occurrence and Chemistry of Zinc in Freshwaters – its Toxicity and Bioaccumulation with Respect to Algae: A Review Part 2: Toxicity and Bioaccumulation with Respect to Algae

Abstract Zinc has definitely been established to be required for the growth of both higher plants and algae, but it can act either in a stimulatory mode or in an inhibitory one, depending on its level of availability. A variety of environmental factors are known to modify the toxicity of zinc in water on algae. It has been observed that algae differ in their tolerance to zinc. It is well known that algae can accumulate zinc or other metals from water, producing an internal concentration greater than in their surroundings. The modes of accumulation and concentration factors are given.
