Multiple Choice

For non-smokers in Canada, what is likely the most significant source of cadmium exposure?

Cadmium exposure for non-smokers in Canada mainly comes from the foods we eat. Cadmium occurs in a range of everyday foods and tends to accumulate in crops as they grow in soil containing cadmium. Because people ingest these foods daily, dietary intake becomes the largest contributor to overall cadmium body burden for non-smokers. In contrast, inhaling cadmium from air is a bigger concern for people with occupational exposure or living near heavily polluted sites, not the general non-smoking population. Drinking water cadmium levels are kept low by regulation, and while soil near gardens can contribute to cadmium in crops, the cumulative dietary intake from many foods remains the dominant exposure route.
