Purpose, the main tasks.

Continuation of database completion with data dealing the evaluation of precipitations and acids oxides in atmosphere of ecological stationary Hincesti.

Research directions:

  • Assessment of the natural / anthropogenic ecosystems state, estimation of antropic impact on environmental components on local and transboundary context;
  • Calculation of mineral ions quantity in soil brought by rains;
  • Quantitative and qualitative monitoring of atmospheric depositions;
  • Modelling of pollutants dispersion in dependence of meteorological parameters

Key achievements:

The researches demonstrate that the Republic of Moldova is situated in zone with the influence of acid rains and 96% of all rainfall water samples have pH ≤ 7.50; the quantitative content of analyzed ions varies widely within a rain from the high values in the first samples at the beginning of the rain and minimum values in the end. Acidity has an inverse behavior; changes in ion concentration are in close relations with the direction of frontal air masses. Western components increase their content, air pollution in Moldova occurs from upper layers of the atmosphere with descending air masses; during the warm season there are recorded increased concentrations of ions in precipitation and precursors of acid rain – acidifying oxides - SO2, NO2 and SO42- in the atmosphere; before the rainfall an increasing content of sulphur oxides, nitrogen dioxide and aerosol SO42- and a decreasing concentration after the rainfall event is observed in the air.
