Copyright holder: European Environment Agency (EEA).</SPAN></P></DIV></DIV></DIV> The identification of 'problem areas' (areas affected by eutrophication) and 'non-problem areas' (areas unlikely to be affected by eutrophication) is based on the application of a multi-metric indicator-based eutrophication assessment tool named HEAT+. HEAT+ follows a stepwise approach ultimately resulting in an integrated assessment of eutrophication states: - Step 1: indicators are grouped as follows: (1) nutrient levels, (2) direct effects, and (3) indirect effects. - Step 2: for each indicator, a eutrophication ratio (ER) is calculated based on monitoring data from the period addressed as well as a target value: ER = indicator value/target value (1). - Step 3: within groups, an average ER is calculated. - Step 4: for each group, eutrophication status is classified in five classes based on the average group-specific ER, e.g. high: 0-0.5; good: 0.5-1.0; moderate: 1.0-1.5; poor: 1.5-2.0, bad: > 2.0, where high and good are equivalent to non-problem areas and moderate, poor and bad are equivalent to problem areas. - Step 5: the classifications are integrated, combining groups based on the 'one out, all out' principle.
