Aquatic Toxicology deals with the mechanisms of toxicity and the responses to toxic agents in aquatic environments at the community, species, tissue, cellular, subcellular and molecular levels, including aspects of uptake, metabolism and excretion of toxicants (Nikinmaa & Tjeerdema, n.d.). Toxicology is the science of the study of poisons. This regulation is designed to make information about hazardous chemicals that are present in work places available to exposed . The main advantage of toxicity test is the fact that it is not necessary to deploy this test on many available pollutants. This field of study also includes information on how those potential hazards can affect humans in and around these aquatic environments. 1990), the Food and Drug Administration (FDA 1997, 2004), and the Organisation for Economic Co-operation and Development (OECD 2004, 2005)—have developed documents that provide guidance on testing protocols. The aquatic environment may be considered in terms of the aquatic organisms that live in the water, and the aquatic ecosystem of which they are part. For example, a region with surface water supplies may choose to undertake an aggressive water recharge program in wet years, with the goal of having additional groundwater in . 2 Notes to Table 1: a: Inhalation cut-off values in the table are based on 4 hour testing exposures.
