CLP environmental hazard classification from first principles

CLP environmental hazards require test data to allow classification of substances.  Environmental hazards of mixtures can be classified by calculation, to avoid unnecessary testing of fish (which are vertebrate animals), see https://ttenvironmenta.wpengine.com/clp-knowledgebase/environmental-hazard-classification-of-mixtures/  .

Environmental hazard tests are discussed here: https://ttenvironmenta.wpengine.com/clp-knowledgebase/clp-environmental-hazard-tests/ .

Forms for classifying environmental hazards from first principles based on test data:

First Principles Acute aquatic toxicity

First Principles Chronic aquatic toxicity

First Principles Hazardous to the ozone layer
