The fatty acid compositions of the fish oil and the margarine used are shown in Table 2.
The fish oil is thoroughly purified from dioxin, organochlorine pesticides, PCB’s (polychlorinated

pg/kg). Total DDT and PCB’s are also below the detection levels of 18 and 4.5 pg L-‘, respectively.
Mercury is below the detection level of 5 ~1 L-‘, as are lead and cadmium.
