Aquatic Environment and Toxicology

Pollution of Aquatic systems (Examples: lakes, rivers, oceans, aquifers and groundwater) by large amounts of waste material that modify the water in negative fashion is termed as Aquatic Pollution. This type of ecological deprivation occurs when harmful pollutants are directly or indirectly discharged into aquatic systems without removal of harmful compounds. Aquatic pollution directly leads to suffering of organisms and vegetation that survive in water, including amphibians. Modern toxicology goes beyond the study of the adverse effects of exogenous agents by assimilating knowledge and techniques from most branches of biochemistry, biology, chemistry, genetics, mathematics, medicine, pharmacology, physiology, and physics and applies safety evaluation and risk assessment to the discipline.
