Location map of sampling sites (A1–A3) of trace metals and elements during the firework event days of 2011–2013 and meteorological monitoring sites (M1 and M2). Solid black circles represent environmental monitoring sites, where the concentrations of criteria air pollutants (O₃, PM₁₀, NO₂, CO, etc.) are routinely measured.
