Formerly known as the Aquatic Toxicity Workshop (ATW), CEW is Canada’s predominant annual meeting in the field of ecological toxicology and related disciplines.  It provides the opportunity to share information on current and emerging topics of regional, national and international importance related to contaminants in ecosystems, both aquatic and terrestrial. Participants include students, academics, government scientists and regulators, environmental consultants and industry representatives. For more information about the CEW, see About.
