Abstract: Potential effects of climate variability can be felt in the distributi<strong>on</strong>, transport<br />

and c<strong>on</strong>centrati<strong>on</strong> of air pollutants. Epidemiological studies have shown that air pollutants,<br />

differing in their chemical compositi<strong>on</strong>, reacti<strong>on</strong> properties, emissi<strong>on</strong>, and persistence in<br />

the envir<strong>on</strong>ment, ability to be transported in l<strong>on</strong>g or short distances are associated with a<br />

wide range of effects <strong>on</strong> human health, such as respiratory system, cardiovascular system,<br />

nervous system, urinary system and digestive system. This study evaluated the associati<strong>on</strong><br />

between daily levels of air pollutants, such as NO, NOx, NO2, CO, SO, O3, NH3, PM2.5,<br />

PM10 and meteorological data (wind directi<strong>on</strong>, wind speed, air temperature, air pressure,<br />

humidity) <strong>on</strong> cases of illness, from January 2011 to December 2011. Using a descriptive<br />

statistics in SPSS program (Statistical Package for the Social Sciences), we analyzed<br />

possible associati<strong>on</strong>s between the mean air pollutants and the rate of cases of health effects<br />

during the year 2011. The statistics data was performed using ANOVA One-away method<br />

with Tukey’s-b test. The results using these method show the following aspect: the mean<br />

of pollutants (NO, NOx, NO2, CO, PM2.5, PM10), meteorological parameters (wind<br />

directi<strong>on</strong>, air humidity and air pressure) and health diseases (rheumatics, heart diseases,<br />

infectious disease, diabetes) was recorded maximum values in winter time (1 january-30<br />

marts2011). In the case of oz<strong>on</strong>e and sulphur dioxide did not shown links between their<br />

maximum values with cases of health diseases. This data study has shown how daily<br />

variati<strong>on</strong> of air pollutants have significantly effects <strong>on</strong> people’s health. Another method for<br />

analyze the statistics data used in this study was the bivariate correlati<strong>on</strong>. In the case of<br />

positive values generated, can observe a significant correlati<strong>on</strong> between health diseases<br />

and air pollutants as follows: rheumatics and NO2; heart diseases and NOx, NO, NO2, O3,<br />

PM10, CO; diabetes and NO, Ox, NO2, O3;, infectious disease and NO2, PM10;<br />

respiratory diseases and SO, NO2, air temperature, air humidity; urology diseases and SO,<br />

NO, PM10, air temperature, air humidity. A very significant correlati<strong>on</strong> resulted of<br />

analysis between O3 and neurology, endocrinology, gastrointestinal disease. There is no<br />

correlati<strong>on</strong> between PM 2.5 and endocrinology disease and gastrointestinal disease. In the<br />

case of negative values generated, it has revealed a very significant correlati<strong>on</strong> between air<br />

pressure and all health disease analyzed in this study. Between CO and diabetes,<br />

respiratory diseases and urology diseases not found any correlati<strong>on</strong>. Results presented here<br />

suggests that elevated levels of air pollutants (below the current limits set by the<br />

Envir<strong>on</strong>mental Protecti<strong>on</strong> Agency), are associated with an increase in the rate of health<br />

effects; but some results presented above also reveal a n<strong>on</strong> correlati<strong>on</strong> between some air<br />

pollutants such as CO, air pressure, PM 2.5 and health diseases.<br />
