Trends of lead in suspended particulate matter in Zagreb air
Monitoring of lead in Total Suspended Particulate Matter (TSPM) started in Zagreb, Croatia in 1971 at three measuring sites. Monitoring of lead concentrations in PM10 started in 1999. This paper presents the trends of annual mean values for lead concentrations in TSPM and in PM10 particles. The obtained data showed a decreasing trend of lead in TSPM, especially during the last ten years when the consumption of lead-free gasoline increased. Lead in PM10 also decreased during the period of measurement.
