Active moss biomonitoring is widely applied in polluted areas for monitoring of airborne particle-bound trace element pollution. This study explored the suitability of the moss Sphagnum girgensohnii for biomagnetic monitoring in cities. To this end S. girgensohnii moss bags were exposed at three different microenvironments characterized by heavy traffic - street canyons, a city tunnel and parking garages during the summer and autumn of 2011 in the city of Belgrade. The ferro(i)magnetic PM fraction in the moss samples was quantified by Saturated Isothermal Remanent Magnetization (SIRM) and the measured values were compared with the trace element concentration in the moss samples. SIRM values were significantly different across the considered urban microenvironments. Moreover, a high correlation between moss SIRM values and concentrations of Al, Ba, Co, Cr, Cu, Fe, Ni and Pb was found. These results demonstrate that moss bags can be effectively applied for biomagnetic monitoring of the s...patio-temporal distribution of road traffic and vehicles derived pollutants in urban areas.
