Abstract
Air pollution in large urban areas is still a sanitary emergency even though
significant improvements have been reached in fuel quality and vehicular
emissions. Many air pollutants when inhaled are toxic to humans and can cause
threats to the respiratory system and chest congestion and other health problems.
The correlation between the concentration of atmospheric pollutants and health
impact is not straightforward due to the complexity of atmospheric mixtures and
the antagonistic or synergic effects of pollutants. At the same time public
authorities need tools for the evaluation of their policies for the mitigation of air
pollution. A possible approach to both these problems is the evaluation of
historical trends of air pollution in urban areas to be compared with sanitary data
or for the evaluation of the effectiveness of environmental policies. In this paper
a procedure to evaluate historical trends of air pollution has been developed
using air pollution indexes. Data collected by the air monitoring quality network
in the urban area of Naples from 2001 to 2007 have been analysed to evaluate
three different daily air quality indexes. The different indexes were compared to
check the correlation among them. Some correlation exists among the indexes
considered but the distribution in the defined risk classes was different.
Therefore, the three indexes considered cannot be assumed as equivalent. Only
correlation with sanitary data can help to select which index is the most apt. A
statistical analysis was then developed to obtain an historical trend of air
pollution in Naples. Even though there were some differences, all indexes show
that from 2001 to 2007 the air quality in Naples has, on average, improved.
Keywords: atmospheric pollution, index, urban area, trend, statistics.
