Organic compounds, especially persistent organic pollutants (POP), are of special interest and are included in one of SEPA’s subprograms (Table 4, #9.2). The subprogram includes different groups in the population. On military enlistment, young men are tested for persistent organic compounds in the body. Mercury content is measured in high consumers of fish, and the concentration of flame retardants is measured in samples of breast milk from women who breast-feed. The National Food Administration stores important data from control of pesticides in vegetables, where more than 2 000 samples are taken per year and residues from more than 200 different pesticides are analyzed. To date, no data have been analyzed and reported from this material, but it will be done in the first phase of this SEPA subprogram. Sampling of breast milk will continue with the intent to monitor organic environmental pollutants. Already existing is a long time series on the concentration of flame retardants and PCB in breast milk. Concurrently, samples will be transferred to the environmental sample bank at the Swedish Museum of Natural History (NRM), which means that samples will be available for comparison in the future.
