    This Environmental Health course provides an introduction to environmental health, including risk assessment and management, toxicology, and other foundational principles. All components of this training are free, including registration, learning, testing, and a certificate of completion. This course is intended for undergraduate- and graduate-level students of medicine, environmental sciences or public health. 

    This Environmental Health course was developed in partnership with the Association for Prevention Teaching and Research and the U.S. Centers for Disease Control and Prevention (CDC). This course is co-sponsored by: the International Society of Doctors for the Environment, Physicians for Social Responsibility, Simon Fraser University's Faculty of Health Sciences , and the University of the Incarnate Word. Like all NextGenU courses, it is competency-based, using competencies from the Association of Schools and Programs of Public Health and the Association of Schools of Public Health in the European Region. This course uses learning resources from world-class academic and governmental organizations such as Harvard Medical School, the U.S. Centers for Disease Control and Prevention, the U.S. National Institutes of Health, and the World Health Organization. The course developer is Lindsay Galway, and our Advisory Group is: Ryan Allen, PhD; Kristian Dubrawski, PhD; Sylvia Struck, PhD; and Tim Takaro, MD, MPH, MSc.
