ResumoUsing X-ray powder diffraction it is possible to identify a number of discrete compounds of nitrogen and sulphur in atmospheric aerosols. The compounds observed include ammonia neutralization products of airborne acids, including mixed ammonium nitrate-sulphate salts. Products of hydrogen halide displacement by HNO3 and H2SO4 are identified both from size-differentiated ion balance studies and X-ray diffraction. A number of mixed metal-ammonium sulphate salts are attributed to reactions of ammonium sulphate subsequent to aerosol coagulation processes.
