The aim of this study was to compare the personal exposures of particles and microbes with the exposure being assessed by stationary samplers in the main microenvironments, i.e. home and the workplace. A random sample of 81 elementary school teachers in eastern Finland were selected to perform the two wintertime 24-h measurement periods. Particle mass concentration, black smoke (BS) concentration and concentrations of viable and total microorganisms on the sampled filters were determined using personal exposure sampling and microenvironmental measurements in homes and workplaces. In this paper, the correlations between different pollutants in each environment and correlations between personal exposures and home and work concentrations are presented. The results show that personal BS exposures correlated with both home and work BS concentrations. Furthermore, the concentrations of viable fungi and bacteria were related between personal and home concentrations. The time weighted microenvironmental model underestimated the personal exposures of particle mass, viable fungi, total fungi and total bacteria concentrations but the model might satisfactorily assess personal exposure to concentrations of BS and viable bacteria. The mass concentration of total fungi and bacteria was <1% of the total particle mass concentration.
