A survey of atmospheric aerosols in a suburban area near Tokyo, Japanwas conducted using an Andersen sampler. Significant amounts of Na⁺and Cl^- collected were considered to be derived from sea salt. The difference between the Na⁺/Cl^-ratio in the area and that in sea salt indicated a considerable loss of Cl^-. This is assumed to be caused by the formation of NaNO₃, which is one of the main nitrate species present. Most of the sulfate in the sample was found to be (NH₄)₂SO₄ in the form of fine particles, which is different from the sulfate derived from sea salt and soil. The size distributions of K and Mg are also discussed in relation to particular sources.
