Lead, manganese, and cadmium content in PM10 and PM2.5 particle fractions--a pilot study.

This paper describes a pilot study of lead, manganese, and cadmium content in thoracic particle fraction and high-risk respirable fraction of airborne particles. Samples were collected at one measuring site in Zagreb during autumn 1998 and spring 1999. The results show that the total heavy metal contents is found in the high-risk respirable particle fraction, and point to two main pollution sources, the first for lead and manganese and the other for cadmium.
