Abstract

In the case of Alpine rivers, nutrient concentrations are largely very low as shown in the map, with values less than 10 mg/l and in many cases even less than 2 mg/l for nitrates (NO3). Only in very few cases, the values reach levels up to 25 mg/l – a number which still can be considered as unproblematic to human health, since the threshold value for nitrates in drinking water is specified at 50 mg/l in most of the Alpine states.
