Coarse Technogenic Material in Urban Surface Deposited Sediments (USDS)

In the current paper, analysis of heavy mineral concentrate (Schlich analysis) was used to study particles technogenic origin in samples urban surface-deposited sediments (USDS). The USDS were collected residential areas 10 Russian cities located different economic, climatic, and geological zones: Ufa, Perm, Tyumen, Chelyabinsk, Nizhny Tagil, Magnitogorsk, Novgorod, Rostov-on-Don, Murmansk, Ekaterinburg. number determined coarse particle size fractions 0.1–0.25 0.25–1 mm. types studied by scanning electron microscopy (SEM) analysis. amount material differed from city city; fraction varied range 0.01 0.43 with an average value 0.18. represented lithoid granulated slag, iron silicate microspheres, fragments brick, paint, glass, plaster, other household waste. Various morphological characteristics as well chemical composition. novelty significance comprises following: it has been shown that are contained a significant part USDS; quantitative indicators accumulation landscape have determined; contributions various total estimated for landscape; trends transformation typomorphic elemental associations associated demonstrated; alteration microelemental content revealed, taking into account impurities composition particles.
