| Baseline | No. of indicators reported per response | Reference values for nutrients were assessed based on analysis of historical data from the period 1960-1965 taking into account the median of these values after outliers were canceled. (14) Reference values for oxygenation conditions were assessed based on historical data analysis in the period 1960-1965 taking into account the limits between which stood 80% of values. (4) |
