- Abstract
A biomonitoring study of air pollution using lichen Flavoparmelia caperata (L.) Hale was conducted at indoor and outdoor environments of primary schools of rural and urban areas of mainland Portugal. This work concerns the chemical characterization of samples by instrumental neutron activation analysis using short irradiations; the mass fractions of Al, Cl, K, Mn and V were determined. Using the latter, the outdoor pollution sources influencing the studied indoor classrooms, namely, sea salt spray and industry, could be assessed. Resuspension of settled dust, playing an important role, was also confirmed.
