Although most molluscicides are biodegradable, some detoxification or deactivation may be required to meet State and Federal discharge requirements. Deactivation compounds may be recommended or be required by the label during molluscicide use or before discharge.
Proprietary deactivants or detoxicants are available. Bentonite clay in a dry or slurry form is a standard agent for several of the nonoxidizing compounds, added to the system discharge upstream of its outlet to the environment. Binding properties of the clay generally render the biocide inactive.
