What is persistence of a chemical?
Persistence is usually described as the half-life (T ) of a chemical in water, soil, sediment, or air. The T is the amount of time necessary for a given amount of chemical released into the environment to decrease to one-half of its initial value.
Is persistence a hazard criteria?
Persistence is a hazard criterion for chemicals enshrined in chemical regulation worldwide. In this paper, we argue that the higher the persistence of a chemical, the greater the emphasis that it should be given in chemicals assessment and decision making.
Why is high persistence alone a cause of concern?
