Abstract
Modern analytical methods of the investigation of platinum-containing objects are considered, including the features and possibilities of the combined methods to determine trace amounts of platinum and palladium in surface water, soil and rocks. The data on metal content, the forms of their occurrence in geochemical systems and in technogenic sources from which they inter the environment are reported. The migration behaviour of different forms of platinum and palladium under the conditions characteristic of natural systems are considered, along with the results of model studies of the sorption behaviour of these elements at geochemical barriers.
