Methylmercury in serum (S-MeHg) was assessed from serum concentrations of total (S-TotHg) and inorganic mercury (S-InoHg), determined by cold vapor-atomic absorption spectrometry. The samples were collected from 135 women on two occasions, in 1968--1969 and 1980--1981. In a subgroup of 29 women, an association was found between S-MeHg and the amount of fish consumed in 1968--1969. The association was stronger when the individuals` mean S-MeHg from 1968--19659 and 1980--1981 were plotted vs fish consumption 1968--1969. In the group, as a whole, there was an association between S-InoHg and number of dental amalgam surfaces, in both 1968--1969 and 1980--1981. The S-InoHg increased by approximately 0.1 nmol/L per amalgam tooth surface, corresponding to an uptake of approximately 0.2 {micro}g/day per amalgam surface, but with considerable interindividual differences. The levels were lower in 1980--1981 than in 1968--1969 for both MeH and InoHg.
