We focus on developing tools and technical resources to assess the impacts of chemical, physical, and biological stressors on ecosystems. The main basis for its development is the classical toxicology—studies of chemical compounds' effects on man, but ecotoxicology is the original part, following it. Ecotoxicology is an international journal devoted to the publication of fundamental research on the effects of toxic chemicals on populations, communities and terrestrial, freshwater and marine ecosystems. Ecotoxicology and Environmental Safety. Ecotoxicology is an integration of the ecological and toxicological effects of chemical pollutants on populations, communities and ecosystems combined with the fate (i.e., transport, transformation and breakdown) of pollutants in the environment. In this regard, ecotoxicology can serve to evaluate the early effect of various pollutants through the use of a series of tools (molecular tests, bioassays, transplantation of organisms, etc.) The scope of the journal covers three main themes. The second section introduces organismal ecotoxicology and examines effects to biochemicals, cells, organs, organ systems, and whole organisms, and bioaccumulation and bioavailability of contaminants. The ultimate goal of ecotoxicology is to reveal and predict the Figure 1. Our current focus is on aquatic ecosystems. Sub-lethal effects, and changes to the environment, can have a greater impact on population size than does acute toxicity. Ecotoxicology is essential in environmental impact assessment (EIA) or in any environmental assessment for the following interrelated reasons which, together with caveats and cautions provided, must be clearly laid out within the framework of the National Environmental Policy Act (NEPA .
