Азот в водах Западного Поозерья

Abstract

Results of study of nitrogen compounds content in superficial and underground waters of western part of Byelorussian Lakeland, heavily used in an industry and agriculture are considered. Is shown, that the accumulation of nitrogen in waters is closely connected with anthropogenic loading of territory and depends on landscape and pedogenic rocks. Anthropogenic pollutions causes a forming of a new type of underground waters HCO3 - NO3 - Ca2+ instead of HCO3 - Ca2+ previously occurred within territory studied. A positive correlation (r=0,60) was found between the nitrates content in this type of water and land plowing up. In rivers nitrates content was lower than maximum permissible concentration, but higher than in lakes.
