This indicator is defined as the number of days where PM10 concentration in yg/m3 at ground level exceeds the norm values.
This indicator monitors global warming and climate change processes. A reduction of greenhouse gas emission, ozone concentration and PM10 levels is of high political priority.
Air pollution by small particles is related to urbanization and industrialization. Areas where the PM10 concentration exceeds norm values most frequently can be found In Belgium, the Netherlands, Germany, Poland, Romania, northern Italy and France. Generally, a zone of higher pollution extends from northeast France through Germany and Poland to the western coast of the Black Sea. In an all- European comparison, BSR is mostly a region of modest and medium air pollution by PM10. However, the level of pollution increases gradually from north to south extending to the highest levels for all Europe in the south of Poland.
