Using a panel dataset, containing information from Romanian industrial sector, this paper analyse the determinants of the pollution abatement expenditure, in the context of transition economy. We consider information related to the pollution abatement expenditure at plant level, plant – specific characteristics, state and local regulatory stringency, market incentives and community characteristics. Our results stress that the population’s potential for collective action in the environmental area is not signifi...

The Earth’s weather and climate are the result of the redistribution of heat. The major source of heat to the surface of the Earth is the sun, principally through incoming visible radiation most of which is absorbed by the Earth’s surface. The ocean redistributes this radiation and the atmosphere with the excess radiated back into space as longer wavelength, infrared radiation. Clouds and other gases, primarily water vapour and carbon dioxide, absorb the infrared radiation emitted by the Earth’s surface and ...

Stara Zagora is one of the biggest towns in Bulgaria located in the middle of the country. In the summer of 2004 two very high level SO2 pollution events happened there, leading to serious discontent among the population. Analogous events happened in 2005, too. An attempt for numerical study of one of these episodes – from 8 to 11 of July 2005 is the subject of the present paper. The Models-3 system was applied for simulation and analysis of the episode with a sequential downscaling to a horizontal resolution of...

Some studies of the MM5/CMAQ modeling system sensitivity to changes of the emissions of ozone precursors are presented in the paper. Tree domains were set over Europe with resolution 90-30-10 km. The most inner domain embraces entirely Romania, Bulgaria and Greece. MM5 was run over these domains for June 2000 with NCEP 1x1 degree Global Analysis data. MM5 was run on the external grids in a “two-way nesting” and over the finer grid in a “one-way nesting” mode. EMEP inventory grid data and its 16.67 km deseg...
