Abstract: 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.
