METHOD FOR DETERMINATION OF CONTAMINATION OF BOTTOMSET SEDIMENTS

摘要

Usage: environment, determining dirtiness sediment in reservoirs rybohoz ystven- Nogo and recreational purposes. SUMMARY: sediments extracted for 50 minutes with water at a volume ratio of not less than 1: 8, respectively, are placed in extracts pure and investigated sediment slice eledei tissue, the cytoplasm of cells which is in the temporarily fixed state, is fixed during the regeneration motion of the cytoplasm of cells in the test and control extracts. Test sediments referred to as pure when values ​​of ratios of less than or equal to 1, to slightly contaminated with values ​​of greater than 1 but less than or equal to 3, to the moderately contaminated with values ​​of ratios greater than 3 but less than 5, to highly contaminated with values ​​of greater than or equal 5. Table 6. (A minute at a volume ratio of bottom sediments and water for at least 1: 8. Similarly prepared extracts of control of sediments, known clean-washed and calcined in an extract of the pure bottom o1 Lzhonyy inoculated tissue section stems or leaves of Elodea, which cytoplasm. in place of the cut as a result of mechanical damage stops its movement. Then, under the microscope at a magnification 10x40 recorded since the restoration of dvizhey 00 Yu Yu
