SULFUR, HALOGENS AND HEAVY METALS IN URBAN SUMMER RAINFALL.

The intent of this paper is report wet-period element concentrations for 18 targeted trace elements in the summer rains of the very heavy industrialized city Hamilton, Ontario. Samples were collected from three rain events in the summer of 1985 and although the sampling period represents a small fraction of total summer rains, useful environmental interpretations can be made. In particular, the usefulness and compatibility of two multi-elemental methods of analysis (instrumental neutron activation analysis (INAA) and inductively coupled plasma-atomic emission spectroscopy (ICP) are demonstrated.
