  1. Public health assessment for dioxins exposure from soil.

    Article - En anglais

    Dioxins are among the most toxic anthropogenic chemicals in the environment.

    Their toxicity has been extensively studied in both humans and animals.

    Dioxin-contaminated soil may result in dioxins occurring in a food chain.

    This is especially important for the general population.

    It has been estimated that about 98% of exposure to dioxins is through the oral route.

    In the 1980s, a concentration level of 1 ppb 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in soil was specified as « a level of concern, » based on cancer effects.

    However, recent studies indicate that end points other than cancer are also of concern.

    A health risk analysis scenario based on health effects of TCDD other than cancer is discussed and compared with the projected intake from 1 ppb TCDD in soil.
