For the thousands of chemicals continuously released into the environment, it is desirable to make prospective assessments of those likely to be persistent. Persistent chemicals will remain in the environment a long time. Based on specific criteria for persistence, a binary logic tree can be developed to classify a chemical as "persistent" or "non-persistent" based on the chemical's properties. In this approach, the classification is based on the results of a standardized multimedia model. Thus, the classifications are more comprehensive for multimedia pollutants than classification using single media half-lives. A case study using twenty-six chemicals for three modes of entry into a unit world environment compares the characteristic time calculated from the multimedia model to the classification resulting from the tree.
