| Abstract | Individual particles of malachite, tenorite, paratenorite, laurionite and sphalerite, as well as several intermediate compounds of Cu, Zn, Pb, Cl, OH and CO3 have been identified among particulate matter filtered from Atlantic and Pacific deep water samples. These particulate matter samples were provided mainly by GEOSECS 1972 and 1974 cruises. The detection and the identification of the individual heavy metal compounds were made by a combination of light microscopy, SEM, EMP and XRD. The highest frequency of heavy metal compounds has been found at several North Atlantic and at one South (antarctic) Atlantic stations. The origin of these heavy metal compounds can, at least partly, be ascribed to technological influences, since metallic copper and brass particles are sometimes found associated with, or included in the heavy metal compounds. Others, however, result clearly from growth in the water. |
