ABSTRACT

Qualitative picture of the degree of environmental pollution in Sofia city was obtained
using magnetic signature of road dust. Collection of 117 samples was studied by
magnetic methods and SEM microscopy. The most polluted points are central part of
the city and main crossroads. Both irregular-shaped and spherical particles of high-iron
content are responsible for the enhanced magnetic signal in the road dust.
