Investigation of American lobster, Homarus americanus, for the presence of chlorinated dibenzo-rho-dioxins and dibenzofurans
The polychlorinated dibenzo-p-dioxins (PCDD) are a group of 75 compounds of current environmental concern. Most attention has been focused on the 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8,-TCDD) because of high toxicity exhibited in laboratory animal studies. Polychlorinated dibenzofurans (PCDF) comprise 135 compounds similar to the PCDD in structure and toxicity. The 2,3,7,8-tetrachlorodibenzofuran (2,3,7,8-TCDF) is the most toxic of this group. Two principal sources of PCDD and PCDF in the environment are incineration and as by-products in the manufacture and use of pentachlorophenols. American lobsters (Homarus americanus) have not been previously investigated for the presence of PCDD and PCDF. Lobsters were examined in this study because of their proximity to possible sources of PCDD and PCDF and an ability to concentrate hydrophobic organics such as polycyclic aromatic hydrocarbons (PAH) in the digestive gland.
