A toxicity assessment for the anostracan Thamnocephalus
platyurus and the fish, trout (Oncorhynchus mykiss)
and tilapia (Oreochromis niloticus), exposed to the insecticide
Lannate and its main substance methomyl was conducted
based on LC50 estimation. The bioindicators were
exposed to Lannate concentrations of 0.1-10 mg/l (Thamnocephalus
platyurus) and 1.5-15 mg/l (fish). The crustacean
was also exposed to concentrations of 0.01mg/l -
1mg/l of methomyl.
