title: Results of biomonitoring analyses in Biomonitoring Laboratory, Helsinki, Finland in 1997.
abstract: In 1997 a total of 4848 results of 47 different analytes from blood or urine specimens, were performed in the Finnish Institute of Occupational Health, Biomonitoring Laboratory, Helsinki, Finland. The results of these service analyses were registered in a database with additional information concerning the worker and the work place. The biomonitoring register, containing one or more results of about 30,000 workers, enables the follow-up of chemical exposure on individual or working group levels. In general, the levels of chemicals or their metabolites in biological specimens have been slowly but continuously declined in Finland during the last decade. In 1997 the decrease in the levels of heavy metals was particularly important. The most problematic organic solvent in Finland is styrene. Styrene exposures have remained in unacceptable levels in work places and still in 1997 more than a third of the workers analysed had very high concentrations of styrene metabolites in their urine. In most major analyte groups studied, there were workers whose exposure level exceeded the Finnish biomonitoring action level (BAL), and in about half of the specimens the level exceeded the upper reference limits (URL), of the non-exposed persons.
