The highest concentration of nickel was found in the smallest particles emitted from a coal-fired plant (20). Particles with an MMD of 0.65–1.1 µm contained nickel at a concentration of 1600 mg/kg, while particles of 4.7–11 µm contained 400 mg/kg. Nickel-containing particles released from oil combustion (California, urban area) are in the
