In order to understand the impacts of metals on aquatic ecosystems, it is first important to understand the principles of ecology, what an aquatic ecosystem is, and how metals from all stages in the life of a mine are discharged to these ecosystems. The author then examines the properties of metals and how they enter these ecosystems from mining and other human activities.
The author presents the properties and uses of specific metals that are mined, or byproducts of mining, in Canada and other countries, and the toxic effects of these metals on fish, other aquatic organisms, and humans.
This is followed by an explanation of various toxicity testing methods, their advantages and disadvantages, and how to prevent and control the generation and discharge of acid rock drainage (ARD).
The case studies include mine histories, the toxic metals and/or cyanide that are or were generated and discharged to the aquatic environment, actions taken to prevent and control discharge of these pollutants, and the results of the source control actions.
The course comprises 19 viewing sessions, each of approximately 30–60 minutes duration, plus supporting figures, tables, case studies, references, appendices, and interactive reviews that confirm your achievement of the learning objectives. The total duration of the course is estimated at 12 hours.
