Any minor or unwanted substance introduced into the environment that can have undesired effects.

A polar solvent that is capable of acting as a hydron (proton) donor.

A molecular entity having an available pair of electrons capable of forming a covalent bond with a hydron (Bronsted base) or with the vacant orbital of some other molecular entity (Lewis base).

A substance that increases the rate of a reaction without modifying the overall standard Gibbs energy change in the reaction.

A molecular entity capable of accepting a hydron from a donor (Bronsted acid).

A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.

Any substance that induces the process of apoptosis (programmed cell death) in multi-celled organisms.

An agent that increases the frequency of mutations above the normal background level, usually by interacting directly with DNA and causing it damage, including base substitution.

Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.

Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).

A substance used in a chemical reaction to detect, measure, examine, or produce other substances.

A polar solvent that is capable of acting as a hydron (proton) donor.
