Two programs of trace metal research are being carried out at the Health and Safety Laboratory (HASL). (a) In the surface air program, continuous sampling of the particulates in surface air, has been performed since mid 1967, at about 20 stations extending over almost the entire Wertern Hemisphere. The samples are analyzed for Pb, on a monthly basis. New York City generally has the highest concentration, of these sites, averaging about 2 µg/m3; Miami and San Juan, Puerto Rico are usually within a factor of two of New York. In the Southern Hemisphere, Santiago Chile, often reaches 1 µg/m3 and exhibits a pronounced winter peak in lead concentration.

(b) In the fallout program, V, Cr, Mn, Ni, Cu, Zn and Pb have been analyzed in monthly total and “wet” samples collected in New York City. In general the levels of trace metals at this site approach or exceed any U. S. values reported. The seasonal variations and relationship of wet to total fallout, will be discussed.
