The influence of artificial aeration on chemical composition of bottom sediments and nutrient exchange was investigated in heavily polluted Lake Długie. Analyzed were variations in the content of nitrogen and phosphorus compounds in near-bottom water, interstitial water and bottom sediments. The obtained results have confirmed a positive role of many years’ artificial aeration in reducing the internal loading of nutrients. At the current stage of the survey, it is not possible to determine explicitly whether artificial aeration has had an effect on the chemical composition of bottom sediments.
