Measurements of Wet and Dry Deposition in Timis County, Romania

Summary

Our agency situated in the western part of Romania, was founded in August 1990. The activity area of the agency in Timis county is based on the following data: total area 869700 hectares; population 726000; 82 cities and villages; forest covered area 108184 hectares; 9 natural reservations. A characteristic of the Timis county is the great number of livestock (ca. 2000000 animals) which induce a high pollution level. Thus NH₃ is one of the most important air pollutants in this area. The complexity of the problems is also seen on the legislative side, since Timis county is close to the border and the agency has to take into account the international laws and conventions.

Precipitation measurements, performed periodically, include: volume, pH and conductivity measurements. The atmospheric pollutant concentrations are measured by means of a stationary installation, while the wet and dry depositions are determined by photo-colorimetry and gravimetry, in several places. Heavy metal depositions were monitored in collaboration. Unfortunately the anthropogenic and biogenic emissions are not evaluated.
