Concentrations of thirteen elements in rainwater from the Pittsburgh, Pa., area were analysed by Charged Particle Induced X-ray Emission (PIXE). They were compared to rainwater in a rural area and air particulates in Pittsburgh. Local and non-local contributions are discussed. Washout ratios were calculated and found to be larger for smaller size particles, contrary to general belief. This work demonstrates the convenience of using PIXE.DOI: 10.1111/j.2153-3490.1976.tb00647.x
