List of the Parameters Being Measured

7. LIST OF THE PARAMETERS BEING MEASURED
A list of the determined parameters (Table 1) was almost the one planned. We did not tested chlorophyll and did not conducted bio-testing, because, in Belarus Republic, there are no correspondingly attested governmental laboratories. Involvement of other laboratories, including non-governmental, would be tactless and difficult to organize taking into account limited terms for expedition preparation and late financing. We also included macro-zoo-bentos in the list of the registered hydro-biological parameters, as well as extended a list of the pesticides being tested.
Several parameters (flow speeds and water expenses, temperature, transparence, pH, dissolved oxygen) were measured at the posts where samples were taken, while others were tested at corresponding laboratories (see the Part 2)
