Chlorinated micropoUutants are harmful for man and environment due to their toxicity, persistence, and bioaccumulation. Persistent compounds are very stable and difficult to get metabolized and mineralized by biological and chemical processes in the environment, and as a result, they have become ubiquitous in water, sediments, and the atmosphere bioaccumulation is the result of the lipophilicity of these compounds. Polychlorinated dibenzodioxins and -furans (PCDD/F) are not produced purposely like many of other chlorinated technical products, such as chlorinated biocides DDT, lindane, and toxaphene. The production and use of persistent organic pollutants (POPs), the dirty dozen has now been banned worldwide by the Stockholm protocol. It should be mentioned that about 3000 halogenated products have now been isolated as natural products in plants, microorganisms, and animals," but the total amount of these products is much smaller compared to xenobiotics. 

Dioxins are very persistent organic pollutants that are present in harbours as by-produets of ineomplete combustion and industrial processes (Besselink et al., 2004). Dioxins in sediments are not aeutely toxic, but are known to induce developmental, reproduetive and immune toxicity after ehronie exposure at low levels.

This book brings together what is known about the major classes of these persistent organic pollutants (the so-called POPs). Each chapter reviews our knowledge of the extent of contamination of the various parts of the Great Lakes ecosystem (air, water, sediment, fishes, birds, etc.), what is known about the trends over time of this contamination, and information about the mechanisms by which these compounds are mobilized in the lakes. The following section presents abstracts of the contents of each chapter.

The use of pesticides in Malaysia dated back since after the Second World War. These persistent pollutants were primarily used for agriculture and vector control. DDT, dieldrin and endrin found extensive use before they were banned recently. Most of the other persistent organic pollutants (POPs) have been banned in Malaysia. However, residues of these pesticides were found in various compartments of the environment such as water, sediment and biota. Nonpesticide POPs were not monitored as much but recent efforts have included monitoring and management of these POPs among other hazardous chemicals. This chapter presents the current status of POPs in Malaysia and various initiatives to manage these pollutants.
