Marine Ecology Research Article

Marine toxicology deals with the study of the impacts of synthetic chemicals and some natural substances and on aquatic organisms at a range of levels of organization. Marine toxicology includes various sub divisions such as toxicology, marine ecology and marine chemistry. General tests to measure toxicity comprise regular acute and chronic toxicity tests. The primary utility of these toxicity tests is to measure endpoints which include survival, growth and reproduction of test organisms along with control organisms. Aquatic toxicology is the study of the effects of manufactured chemicals and other anthropogenic and natural materials and activities on aquatic organisms at various levels of organization, from subcellular through individual organisms to communities and ecosystems.[1] Aquatic toxicology is a multidisciplinary field which integrates toxicology, aquatic ecology and aquatic chemistry.This field of study includes freshwater, marine water and sediment environments. Common tests include standardized acute and chronic toxicity tests lasting 24–96 hours (acute test) to 7 days or more (chronic tests). These tests measure endpoints such as survival, growth, reproduction, that are measured at each concentration in a gradient, along with a control test. Typically using selected organisms with ecologically relevant sensitivity to toxicants and a well-established literature background. These organisms can be easily acquired or cultured in lab and are easy to handle
