Organochlorine pesticide (OCP) residues in foods have been of concern for several decades. However, the analysis of some of the OCPs and their metabolites or derivatives, such as endrin aldehyde, endrin ketone, nonachlor, etc. in fatty foods (including foods of animal and plant origin), was not commonly included in routine monitoring programme. Recently, the Stockholm Convention introduced nine plus one new persistent organic pollutants (POPs) that included chlordecone and some other OCPs. Is there a method available that can analyze both traditional OCPs, together with their metabolites and derivatives in fatty foods? Furthermore, is there a suitable method that can monitor OCPs and the newly added POPs including chlordecone in fatty foods together in a pot? This review aims to provide some background information to answer these questions.
Organochlorine pesticides (OCPs) were intensively used in
agriculture to protect cultivated plants in mid-twentieth century. The use of
pesticides in the USA doubled from 1960 to 1980. 1,1,1-Trichloro-2,2-bis(4-chlorophenyl)ethane
(DDT), one of thecommon OCPs, was used to prevent
spreading of malaria and other vector-borne diseases such as dengue,
leishmaniasis and Japanese encephalitis through the prevention of growth of
mosquito. Lindane, another example of the most widely used OCPs, had been used
to treat head lice in children . After OCPs
were used widely in soil and plants for some years and due to their relative
stability and bioaccumulation property, these persistent chemicals can be
transferred and magnified to higher trophic levels through the food chain.
Consequently, OCP residues are present in fatty foods, both foods of animal
origin, such as meat, poultry, fish, eggs, and milk, and of plant origin, such
