Persistent organohalogen contaminants

C., Verreault, J., Vijayan, M.M. and Gabrielsen, G.W. (2010) Exposure and effects assessment of persistent organohalogen contaminants in Arctic wildlife and fish. Sci Total Environ, 408, 2995-3043. 

This chapter is divided into seven main sections. The first of these sections is focused on technological contaminants, namely heterocyclic amines, acrylamide, furan, chloropropanok and their fatty acid esters, polycycKc aromatic hydrocarbons, monocyclic aromatic hydrocarbons, nitroso compounds, and ethyl carbamate. Other sections deal with microbial toxins (mycotoxins and bacterial toxins), persistent organohalogen contaminants (such as polychlorinated biphenyls, dibenzodioxins and dibenzofurans), chlorinated ahphatic hydrocarbons, pesticides (persistent chlorinated hydrocarbons and modem pesticides), veterinary medicines and contaminants from packaging materials. Presented for each of these contaminants are structures, properties, occurrence and the main sources of dietary intake, mechanisms of formation, possibilities of food contamination, prevention and mitigation and health and toxicological evaluations. 

A large number of aromatic chemicals and organohalogen compounds released from anthropogenic sources into the environment are recognized as harmful and persistent contaminants. The removal of these HOCs from water and wastewater has been and still is central to research in environmental science and technology. One of the major approaches is sorption technology using appropriate sorbents such as activated carbon, siliceous materials, alumina, zeolite, and synthetic resins [3]. In recent years, sorption behaviors of HOCs by native and chemically modified polymers...
