Prioritization may be the First action in the entire process of assessing current chemicals beneath the Poisonous Substances Management Act (TSCA) which is codified inside of a remaining Chemical Prioritization System rule. The goal of prioritization should be to designate a chemical compound as both higher precedence for instant further more threat analysis, or minimal precedence, for which threat analysis just isn't warranted at some time.
