In Toxic Trespass, intrepid filmmaker Barri Cohen launches an investigation into the effects of the chemical soup around us. She starts with her 10-year-old daughter, whose blood carries carcinogens like benzene and the long-banned DDT. Then Cohen heads out to Windsor and Sarnia, Canadian toxic hotspots with startling clusters of deadly diseases. The filmmaker journeys into toxic nightmares all too common in industrialized countries. She meets passionate activists working for positive change, along with doctors and scientists who see evidence of links between environmental pollution and health problems. And she learns how quickly barriers can go up sometimes, when authorities are questioned about the connection between toxins and serious health problems. This film is essential viewing for anyone concerned about the effects of pollutants on our – and our children’s – very DNA.

Exposure: Environmental Links to Breast Cancer

  • Winner, Best Health Documentary - New York International Independent Film Festival, 2001

  • Broadcast on CBC Newsworld, TVO, Women's Television Network and several international broadcast outlets.

Director: Francine Zuckerman, Producers: Martha Butterfield & Francine Zuckerman Associate Producer, Principal Research Consultant: Dorothy Goldin Rosenberg

This video was conceived in response to the growing public debate about the implications of our contaminated world on the health of women. Today one in three people will get cancer. One in four will die from it. In the 1950s, women in industrialised countries were at a one in twenty risk of developing breast cancer over their lifetime. Today that risk has skyrocketed to one in eight. Cancer can have many causes. Seventy to eighty percent of women with breast cancer have none of the "official" risk factors: family history (5-10%), hormonal and reproductive factors and a high fat diet. However, breast cancer rates are increasing all over the world and may be but the tip of the iceberg of other environmentally linked diseases. Timely, responsive and urgently needed, Exposure: Environmental Links To Breast Cancer can play a major role in raising awareness around the little understood, long-term connections between environment, health and disease prevention. It introduces issues and raises questions, awareness and opportunities. It offers strategies for dealing with current unacceptable environmental health conditions and for generating the social and political changes needed for a cleaner, safer world.
