ABSTRACT The general objectives of the SEAREX Program are (1) the quantitative measurement of atmospheric fluxes of selected heavy metals (e.g., Pb, Cd, Zn, Se, Sb, As, Cu, Hg, Ag), “!°pb and its daughter *!°po and organic compounds such as the man-associated PCB, DDT, polynuclear aromatic and « aliphatic hydrocarbons, phthalate plasticizers and the natural occurring steroidal and terpenoid hydrocarbons, fatty acids and alcohols, low molecular weight compounds such as ketones, aldehydes, and carboxylic acids to the ocean surface, (2) the identification of the sources for these substances in the marine atmosphere and (3) the investigation of mechanisms of exchange of these substances across the sea/air interface. wears. ee tees mec fe i aR Farageet EYFes dé
