Description
| - Water composition in the watershed-lake ecosystem of Pr.beta.Üilsk.theta. Lake has been strongly affected by atmospheric acidification and forest decline. In 1998,all surface tributaries were acidic (pH 3.75-4.87) with sulphate and nitrate the major anions. Tributaries draining sub-watersheds with damaged forest had increased nitrate concentrations (up to 2.4 mg l/1 NO<sub>3</sub>-N) and the elevated losses of base cations. In-lake biochemical processes significantly influenced lake water chemistry during the summer temperature stratification, when pH, acid neutralizing capacity, K<sup>+</sup>, ammonium,DOC,TP,and Fe concentrations were elevated, while nitrate and ionic Al (Al<sub>i</sub>) were lowered. Biological nitrate removal and reduction of ferric oxyhydroxides resulted in alkalinity generation and in pH increase in the hypolimnion. Under higher pH, Al<sub>i</sub> species hydrolyzed and formed particulate Al hydroxides, which adsorbed orthophosphate. This process elevated concentrations of
