ABSTRACT

 

The present paper reports the results of a statistical analysis of particulate matter (PM10). The concentration values were gathered from one of the five automatic stations situated in Dolj County continuously monitoring air quality during a period of one years (between July 1st, 2011 and June 30th, 2012).

A log-normal distribution is proved to best fit the experimental curve.

The distribution is also related to the wind velocity, showing that in most cases a low value of the wind speed leads to a high value of the pollutant’s concentration.
