	Ecotoxicology - Wikipedia, the free encyclopedia
		The term "ecotoxicology" was coined by Truhaut in 1969, who defined it as "the branch of Toxicology concerned with the study of toxic effects, caused by natural or synthetic pollutants, to the constituents of ecosystems, animal (including human), vegetable and microbial, in an integral context” (Truhaut, 1977).
		Ecotoxicology is alleged to be the integration of toxicology and ecology or, as Chapman (2002) suggested “ecology in the presence of toxicants”.
		This systemic study is distinctly separate to the anthropocentric nature of classical toxicology and consequently ecotoxicology is a far broader discipline incorporating aspects of classical ecology, behavioural ecology, toxicology, physiology, molecular biology, environmental chemistry and a wealth of other disciplines in studying the movement of toxins through an ecosystem.

	ASE - Australasian Society for Ecotoxicology - Australasian J. Ecotox. (Site not responding. Last check: 2007-10-29)
		Ecotoxicology addresses the effect of single chemicals and complex mixtures on a wide range of species in the environment, as well as on interactions between species, and it encompasses a variety of approaches for both laboratory and field assessments, as well as modelling and prediction.
		The science of ecotoxicology can address many of the wide variety of environmental issues that this region faces and it is intended that the papers published in this journal will reflect this variety.
		The newly formed Australasian Society for Ecotoxicology will be active in promoting the acceptance and constructive use of ecotoxicology in managing and protecting the environment and in rehabilitating past mistakes.

	Ecotoxicology for tropical wetlands
		Ecotoxicology seeks to understand how toxic chemicals (toxicants) affect the structure and function of natural ecological systems (populations, communities and ecosystems).
		The eriss ecotoxicology program was established in the late 1980s to assess the toxicity of, and determine 'safe' dilution levels of waste water from the Ranger uranium mine in Kakadu National Park.
		Whole organism toxicity bioassays have been developed at the ecotoxicology laboratory to determine the acute and chronic toxicity of chemicals, environmental samples or complex effluents, to tropical freshwater organisms.

	Ecotoxicology
		Ecotoxicology integrates the ecological and toxicological effects of chemical pollutants on populations, communities, and ecosystems with the fate of such pollutants in the environment.
		The term ecotoxicology was first used in 1969.
		Rachel Carson and the publication of Silent Spring in 1962 had an instrumental role in raising public and lawmaker's awareness to the dangers of using chemicals.

	Ecotoxicology Research Group
		Ecotoxicology can be seen as an important part of the broader field of response biology.
		The prediction of environmental risk of contaminants (prospective) and the assessment of environmental damage (retrospective) is an important goal in protecting the form and functioning of ecosystems and the setting of environmental standards.
		Due to the fact that organisms from different species vary in their sensitivity towards chemical substances it is difficult to set standards for protection of species with regard to pollutants in the environment.

	Nondestructive Biomarkers in Ecotoxicology
		This article was presented at the NAPA Conference on Genetic and Molecular Ecotoxicology held 12-15 October 1993 in Yountville, California.
		In the last 20 years, ecotoxicology has been increasingly concerned with the use of biomarkers to evaluate the biologic hazard of toxic chemicals and in the assessment of environmental health.
		In conclusion the nondestructive biomarker approach appears to be a useful tool in ecotoxicology, particularly in the hazard assessment of endangered species of vertebrates.

	Ecotoxicology and Environmental Fish Health Program - Environmental Conservation - Northwest Fisheries Science Center (Site not responding. Last check: 2007-10-29)
		The core mission of the Ecotoxicology and Environmental Fish Health Program is to determine the impacts of human activities on the health of wild fish, especially Pacific salmon and marine fish.
		To do this, the program has five research teams, four of which focus on different aspects of fish physiology and biology, and one of which focuses on assessing risks posed to fish health by human activities, especially the releases of chemical contaminants into freshwater, estuarine, and marine waters.
		While the primary expertise of the Program is in ecotoxicology, there is substantial effort made to assess the normal physiology of wild fish, and natural variations in response to non-anthropogenic factors, as a backdrop against which human activities, such as the release of toxic chemicals, can be assessed.

		Human beings are not isolated from the natural environment; they are an integral part of it and have modified it by their activities.
		These would be analytical levels in the appropriate tissues or fluids which should not be exceeded if adverse effects are to be avoided.
		In the the context of environmental toxicology and ecotoxicology, biological monitoring means biological assessment of exposed organisms in order to detect adverse effects which may indicate their exposure to toxic levels of substances in their environment.
