ABSTRACT
The water flea Moina macrocopa, an important freshwater zooplankter,
is a useful test species for the study of sensitivity to environmental
toxicants, and is recognized as a general representative of other freshwater
animals. The sublethal effect of nickel on hemoglobin concentration and
acetylcholinesterase activity of Moina macrocopa was evaluated, as well
as the usefulness of bioassays using artificial sediments. The results
show that hemoglobin concentration and acetylcholinesterase activity in
the Moina macrocopa test could become useful for routine monitoring to
detect the presence of nickel in aquatic environments.
