Some sulphates and nitrates can also be formed in photochemical smog due to oxidation of sulphur containing components (SO2,  H2S) and NOx (N2O5, NO2) but it does not contain carbon di-oxide (CO2). Photochemical smog materials and causes damage to plants, human health hazards and corrosion problems.
