The doctrine of substances and their effects

.
Since Paracelsus (ca. 1493 - 1541) we know that substances have an effect depending on their quantity (or concentration) absorbed into the organism. Therefore, both qualitative (which substance, which substances?) and quantitative information (which quantity or concentration?) must be available as a basis for a toxicological assessment.

With the knowledge of toxicology and with the help of the application of standardized toxicological methods, we are able to assess harmful effects of chemical substances on organisms. We distinguish between human toxicology and eco- or environmental toxicology. While human toxicology deals with the effects on humans, ecotoxicology has the task of describing the possible damage of products or processes on the living environment. In its final consequence, ecotoxicology of course also serves humans, since environmental damage can have repercussions on humans.
