【 摘 要 】

As part of a monitoring programme conducted by the Institute of Environment and Development (IDAD) and supported by the regional municipal solid waste (MSW) management authorities, an extensive database of trace metals (TMs) concentrations in ambient air was collected in two sites, Leça do Balio (LB) and Vila Nova da Telha (VNT), located in Porto's metropolitan area, north of Portugal. Since 2004, concentrations of As, Cd, Pb, Cu, Cr, Mn, Hg, Ni and Zn were measured in PM10. In addition, total gaseous mercury (TGM) was monitored since 2008. These measurements were used to assess long-term trends of concentrations. Statistical analysis was used to search for the possible origin of the TMs.
