Physiochemical characteristics and oxidative potential of ambient air particulate matter (PM₁₀) during dust and non-dust storm events: a case study in Tehran, Iran.

ABSTRACT: In the present study, we investigated the characteristics of metal(loid)s, polycyclic aromatic hydrocarbons (PAHs) and oxidative potential (OP) in PM₁₀ during dust and non-dust days in a rural and an urban area in Tehran. Water-soluble ions, metal(loid)s, PAHs, and OP were measured using ion chromatography (IC), inductively coupled plasma optical emission spectrometer (ICP-OES) and gas chromatography/mass spectrometry (GC-MS), and dithiothreitol (DTT) assay respectively. The results showed that the average concentrations of ambient PM₁₀ were 284 ± 90.4 and 123 ± 31.4 μg m^-3 on dusty and regular days in urban areas respectively, and were 258 ± 48.3 and 124 ± 41.4 μg m^-3 on dusty and regular days in rural areas, respectively; these values were 95%
