Snails were then exposed to 100 mg l21 cadmium for a further 5 days, and the cercarial emergence was recorded daily.
The present study investigated both individual and combined toxicity of cadmium and zinc, an experimental approach not previously attempted in parasite ecotoxicology.
Cadmium is softer than magnesium, so the covalent character of the metal-sulfur bond will be enhanced further.
The cell preparations removed almost 100% of free cadmium present.
Excystment in vitro was only significantly affected by cercariae exposed to cadmium\zinc mixtures whilst encysting.
Diagnostics of cadmium plasma produced by laser ablation.
Cadmium was visualized as black deposits on the parasite surface.
Both are equally selective for barium and calcium, have a relatively low sensitivity to external cadmium, and a negative activation range.
