In this case an active attention is paid to microplastic particles (MPs) less than 5 mm size and nanoplastic particles (NPs) less than 100 nm in size. MP and NP particles are found practically everywhere: in waters and bottom sediments of the World Ocean, river, lake and groundwater, beach sediments and even in snow and ice of the Arctic and Antarctic, in foodstuff, bottled water, in living organisms at all stages of the food chain. Plastic pollution of the natural environment has already become as global as climate change. This article presents the results of the analysis and summary of the current published literature devoted to the problems of MP and NP pollution of natural waters, mainly on the territory of the Russian Federation. For the first time, a schematic map of MP distribution in surface waters of Russia is constructed. A summary table on MP concentrations in surface water, groundwater, bottled mineral and tap water, bottom sediments of rivers, seas and oceans of the world is presented. It is clearly shown that there is a shortage of studies of MP and NP contamination in groundwater, although their content is also quite high.In addition, the paper touches upon the problem of measuring the MP and NP content and determining its composition, highlights the features, advantages, disadvantages and limitations of all the main detection methods. The summarized schemes of water and soil sampling and preparation for the following MP determination are presented. A reasonable conclusion is made that at the present moment there is no one optimum method, and only a combination of methods allows to identify MP and NP contamination in the best way.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.

Parageneses of albite with chlorite and epidote are only characteristic of peripheral sections of the halo, subjected to the propylite-type alteration. Quartz-potassium feldspar alterations are distributed in the central and deep-seated sections of the halo. Petrographic investigations of hydrothermal alterations and results of the X-ray structural analysis and infrared (IR) spectroscopy of micas from the mineralized quartz-sericite metasomatites were applied to reveal a cryptic mineralogical zonation of the Kyzyk-Chadr porphyry copper deposit. Elements of the cryptic mineralogical zonation, revealed based on results of the X-ray study and IR spectroscopy of light-colored micaceous metasomatites of the deposit, are caused by variable proportions of the phengite and muscovite components in their composition. The phengite component predominates in the central and deep-seated sections of the alteration-mineralization halo of the deposit, while the muscovite component progressively increases toward its flanks and upper sections. This tendency correlates with the general vector of the mineralogical alteration-mineralization zonation and are supposedly explained by changing PT conditions within the porphyry copper ore-magmatic system. The indicator of the cryptic mineralogical zonation by the “phengite-muscovite” relationship can be applied for prospecting and preliminary evaluation of porphyry copper type deposits, being used as an objective guide for correlation of already obtained ore-grade interceptions and forecasting the ore bodies.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.
