Abstract |
|
|
The harmful
effects of air pollutants on human, animal and vegetation are
the major reason for efforts to control their sources. During
the last decades, research on acidic deposition and analysis of
observational data were followed by scientific understanding of
the relationships between emissions of precursor gases and
deposition of acids or acid-forming substances. Caraş-Severin
County holds many non-renewable resources which have been
intensely exploited using old, pollutant technologies. The
extractive, iron and steel, metallurgic, energy and construction
material industry greatly contributes to the further pollution
of the environment with many pollutants, including gases with
acid effects on the atmosphere. The analysis done between 1997
and 2006 for measuring the dosage of gases with an acid effect
indicates a state of control over the releases and, in the last
final of the decade, a constant level of air quality, below the
maximum allowed limit; there were no states of alarm and the
concentrations of SO2, NOx and NH3 were
within the maximum allowed concentrations. Still, their
polluting effect exists, and this is obvious considering the
acid rains that have occurred, which have had detrimental local
and distant effects on agriculture, vegetation and living
organisms.
