8. DESCRIPTION OF THE POSTS WHERE SAMPLES WERE TAKEN AND HYDRO-METRIC MEASUREMENTS WERE HELD
The posts, where samples had to be taken, were determined together with the places of hydro-metric measurements. Samples of bottom sediments and water samples for further hydro-biological tests (in laboratory conditions) were taken, as a rule, several meters upper-stream the place of hydro-metric measurements.
We measured flow speeds and water expenses at 18 posts. Water samples for measuring hydro-chemical and hydro-biological parameters were taken at 23 posts (20 of them were included in the expedition plan, and 3 were added additionally according to republican scientific and technical themes), samples of bottom sediments were taken at 15 posts, samples of biota were taken at 2 trans-boundary posts, samples of water and bottom sediments for measuring radio-activity were taken at 10 posts. Short description of monitoring posts is presented in the Table 2. The post numbering corresponds to the following scheme: from up to down stream the Dnipro river and its tributaries, the Prypyat river and its tributaries; this way of numbering is the best for presenting the expedition results (see the Part 11).
