Ecological Systems and Devices Annotation << Back About a sampling role in the quantitative chemical analysis of objects of surrounding environment. Part 2. Soil Voronich S.S. Roeva N.N. Khlopaev A.G. Baranov A.N. Jerebina E.N. Orlovskaja O.A. Article is devoted to a sampling role in the quantitative chemical analysis of the soil. In it, in particular, are described how it is correct to choose a site of points for carrying out research (methods of elementary platforms and trial platforms), types of tests (point, combined) and features of their selection (an envelope method). Depth thus usually depends on concentration of polluting substances and research goals (definition of extent of pollution of a blanket, chemical migration on a profile, etc.) also makes 0…20 cm, 20…40 cm and 40…60 cm. The questions connected with a choice of the sampling equipment are rather in detail considered: soil knifes, scoops, pallets, bayonet shovels, and also manual soil drills of various design. In conclusion of the review the main recommended methods of preprocessing of the selected soil tests (drying, crushing and removal of large inclusions, sifting, division by means of a mechanical divider or manually a method of quartation and a crunching) and necessary for carrying out these operations the equipment are presented. Keywords: Soil; trial platform; test (point, combined); envelope method; drill; sample preparation (drying, crushing, sifting, division, crunching); quartation method.
