Trend of cancer risk of Chinese inhabitants to dioxins due to changes in dietary patterns: 1980-2009.

ABSTRACT: Food ingestion is a major route for human exposure and body burden to dioxins. We estimated the potential influence of changes in dietary patterns in Chinese population on human health risk to 2,3,7,8-TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) over the last three decades. We performed multiple modeling scenario investigations to discriminate the contribution of 2,3,7,8-TCDD emissions and changes in dietary patterns to the cancer risks (CR) to dioxins. Results showed that changes in dietary patterns, featured by decreasing consumption of total grain (including all unprocessed grains) and vegetables and increasing intake of animal-derived foodstuffs, caused increasing CR from 7.3 × 10(-8) in 1980 to 1.1 × 10(-7) in 2009. Varying dietary patterns contributed 17% to the CR of Chinese populatio
