The range of acute values for the remaining fresh water invertebrate species clt from 10 ppb for the snail Ancylus sp. Endosulfan sulfate is a metabolite of both the A and B endosulfan isomers of the parent compound endosulfan. An advisory concentration can be derived from a number of sources: The most commonly used trademark of endosulfan is Thiodan.
Although these values are in close agreement with acute values for the same species in the water quality criteria, detailed quality control methods were not mentioned in these studies.
