  1. The influence of sewage sludge applications to agricultural land on human exposure to polychlorinated dibenzo-P-dioxins (PCDDs) and -furans (PCDFs).

    Article - En anglais

    Polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) are organic chemicals of suspected extreme toxicity.

    PCDD/Fs are ubiquitous in the environment and relatively enriched in sewage sludges.

    The deliberate application of sewage sludge to agricultural land can therefore potentially increase exposure of the human population to these compounds via transfers through the foodchain.

    This paper presents a protocol for assessing the background human exposure to all seventeen 2,3,7,8-substituted PCDD/Fs for which toxic equivalent factors (TEFs) are available.

    Background daily human exposure in the UK to 2,3,7,8-T4CDD and I-TEQ are calculated to be 0.0239 ng abd 0.203 ng, respectively.
