Description Using biological assays, the Department of Ecology tested the toxicity of two salts (potassium chloride and magnesium chloride) to the aquatic nuisance species, New Zealand Mud Snail (Potamopyrgus antipodarum). The goal of these bioassays was to find an effective chemical treatment for decontaminating field gear, to prevent spreading snails during field work. None of the treatments we tested were reliably 100% lethal to the snails. We do not recommend using these salts to decontaminate field gear exposed to New Zealand Mud Snails, since they were not found effective at exposures of up to 30 minutes. Alternative decontamination methods are available.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
