Mathematical modeling of sulfur dioxide concentration in the western part of Romania.

Nowadays air pollution is a major issue, due to its effect on the human health and environment. Therefore, in this article, we analyze the evolution of sulfur dioxide (SO2) concentration for eight months (November 2015-June 2016) at three monitoring stations in Timisoara, Romania. The results indicate that the legal limits have been exceeded only a few times and the pollutants' distribution is strongly influenced by the relative atmospheric calm in the County. We also propose a new model for the SO2 dissipation, which takes into account the individual data series, as well as the specific atmospheric conditions.
