Ingestion of contaminated fish can be an important human exposure pathway for dioxins and furans emitted from waste incineration plants. A new method for calculating fish contamination resulting from dioxin and furan emissions has been developed to overcome some of the problems of those currently used. The method is based on evidence that the major determinant of fish dioxin and furan uptake is sediment concentrations. Only two steps are necessary to calculate fish tissue levels. Step 1: Calculation of the concentration of dioxins and furans in particulate matter entering the lake or pond, and hence, the resulting sediment concentration. Step 2: Calculation of fish concentrations utilizing fish-to-sediment ratios for the various dioxin and furan isomers.
食用受污染的鱼类可能是人类接触垃圾焚烧厂排放的二噁英和呋喃的重要途径。为克服当前使用的一些方法存在的问题，已开发出一种计算二噁英和呋喃排放导致鱼类受污染情况的新方法。该方法基于这样的证据：鱼类摄取二噁英和呋喃的主要决定因素是沉积物浓度。计算鱼类组织水平只需两个步骤。步骤1：计算进入湖泊或池塘的颗粒物中二噁英和呋喃的浓度，进而得出沉积物浓度。步骤2：利用各种二噁英和呋喃异构体的鱼与沉积物的比率计算鱼类体内的浓度。
