Canadian Wildlife Service (CWS) Québec region Issue and challenge The contamination of the environment by toxic substances is linked both to industrialization and to agriculture. Toxic substances find their way into ecosystems from discharges and leaks of industrial products, consumer wastes and urban sewage, from farming and forestry runoff, and from accidental spills. Contaminants may be dispersed over great distances by winds and water currents. Some of these compounds (organochlorines and heavy metals) accumulate in animal tissues, particularly in predators that are at the top of the food chain. Organochlorines pose a serious threat, because it can take decades for them to decompose naturally.

47. Ecotoxicology Simultaneously, the term ecotoxicology, or the study of effects of contaminantson organisms, was introduced into the scientific lexicon. http://www.bbsr.edu/Ocean_Human_Health/Ecotoxicology/ecotoxicology.html

During the 1960s, evidence began to emerge of the unwanted effects of human-made chemicals on natural ecosystems. Concern also grew about the unprecedented release of metals, oil and other natural substances associated with human activity. Rachel Carson brought these issues into the public arena in her book, Silent Spring. Simultaneously, the term "ecotoxicology," or the study of effects of contaminants on organisms, was introduced into the scientific lexicon. Considerable progress has been made since then in countries with temperate climates in developing procedures to provide early warning of biological impacts and ecological change. Despite this progress, other environments, such as the tropics and the deep sea, are vulnerable to pollution in part because of the lack of scientific information regarding these ecosystems. BBSR's analytical chemistry expertise is recognized by the United Nations and other organizations dealing with global contamination. In addition, recent development of molecular biology facilities at BBSR allows the mechanisms of pollutant effects to be investigated in great detail. Not only is this research relevant for understanding how chemicals affect wildlife, but it also permits early detection of threats to human health. Ecotoxicological research is also being carried forward through these BBSR initiatives:

Contact us What is ecotoxicology? Ecotoxicology can be seen as an important part of the broader field of response biology. It is the study of how biological systems (from the molecular and cellular through to the ecosystem level) respond to stress caused by environmental contaminants. It brings the disciplines of ecology, physiology and toxicology together and focuses on the effects of pollutants on populations, communities and ecosystems. [back to contents] Are there job opportunities in this field of study? In order to comply with international standards (such as ISO) when exporting products to Europe and other First World countries, South African industries are required to meet stringent environmental standards and submit to regular environmental audits. Not only the private sector but various governmental bodies provide career opportunities. Expert knowledge on ecosystem form and function and its responses to chemical threats is required in the following areas: Nature conservation Agriculture and forestry Public health Regulatory bodies involved in registration of chemicals, setting environmental standards and enforcing environmental laws

Ecotoxicology AOE Home Program Information Faculty and Research Student Research Projects Ecology Home ... AOE Home Page Area of Emphasis Ecotoxicology Ecotoxicology is the branch of ecology that combines ecology and toxicology. It deals with fate and transport of pollutants and "with the study of toxic effects, caused by natural or synthetic pollutants, to the constituents of ecosystems, animals (including human), vegetable, and microbial, in an integral context" (Truhaut, 1974). It also includes the study of how toxicants combine with added environmental stressors to affect these systems and their components. "The occurrence and effects of contaminants...implies that only an integrative approach of all factors affecting ecosystem processes will identify the specific role of pollution" and other perturbation (Reinjnders, 1988). Ecotoxicology is a science that emphasizes "responses of individuals, populations, and changes in community, ecosystem structure and dynamics..." The theoretical core of Ecotoxicology is synthetic and based on the principles of hydrodynamics, ecology, toxicology and pharmacology, population biology, community ecology, physiology, biochemistry, and other related disciplines. This AOE has a biological emphasis, and students in this AOE are expected to conduct basic and/or applied thesis or dissertation research relevant to understanding and solving ecological problems associated with contaminants and other associated environmental perturbations and their effects on biological systems and their components.

@import "/styles/percent.css"; Applied Ecotoxicology Group Leader: Dr. Geoffrey Sunahara Phone: (514) 496-8030 Fax: (514) 496-6265 The Applied Ecotoxicology Group is involved in a number of different research projects in the field of soil ecotoxicology, specifically in the application of ecotoxicity tests for ecological risk assessment (ERA) and the monitoring of bioremediation approaches for contaminated sites. The basic understanding and prediction of toxicological effects of complex mixtures of environmental pollutants on key components of the ecosystem are some of our other major objectives. For this purpose, we use different bacterial, plant and earthworm toxicity tests, as well as biochemical markers of exposure and toxicity, to characterize the environmentally hazardous effects of soils contaminated with chemicals. Our research interests include the ecotoxicological impact of organic pollutants such as petroleum hydrocarbons and nitro-aromatics, as well as semi-solid matrices (sludge and soil slurries) containing mixtures of both organic (phenols) and inorganic (heavy metals) substances. Different laboratory and field-based experimental approaches are being applied towards ERA of urban contaminated sites. Other environmental toxicants of interest include PCBs, dioxins, TPHs and heavy metals. The above areas of research will provide the basis for improved design and eventual application of new cost-effective ecotoxicological approaches to characterize the biological impact of pollutants on the environment for accurate and scientifically defensible environmental risk assessment

The long-range aim of this five-year collaborative project is to quantify how low but chronic levels of pollutants affect ecologically important Bay species. My role in the project is to provide the population level modeling for the two target species; the amphipod Leptocheirus plumulosus , and the killifish Fundulus heterclitus We will be doing this by developing both individual-based and stage-based models for both species.
