For investigating relationship between activity of cholinesterase (ChE) and ambient concentration of anticholinesterases, Daphnia magna had been exposed for 21 day to sub-lethal concentrations, i.e. 1/6 EC(50), 1/36 EC(50), and 1/216 EC(50), of either triazophos or chlorpyrifos. Samples were taken at different points of time for measuring total activity and immunoreactive content of ChE and actual concentrations of the anticholinesterases. A type of antigen formerly developed by immunizing mice… CONTINUE READING
