Toxicology includes the fields of forensic, chemical, aquatic, eco- and environmental toxicology, and toxicogenomics. Toxicology is a biological field of study on the harmful effects of chemicals on biological organisms.
Chemical toxicology is used to understand and determine the properties of harmful chemical agents, and to learn the nature of their toxicity on a chemical level. Toxicogenomics focuses on the molecular profiling of toxins. Aquatic toxicology deals with the effects of natural and manufactured toxins on aquatic life. Ecotoxicology focuses on the effects of synthetic and natural pollutants on all biological life, while environmental toxicology focuses exclusively on the effects of pollutants on the environment.
Toxicology is a useful field of study when applied to forensics, and helps determine details in criminal, medical and drug-related analyses.
