Annual average PM10

Atmospheric pollution is the result of the emissions of gases and particulate matter derived from human activity (social and economic) and from natural sources. Among the atmospheric pollutants with different repercussions on the atmosphere, and therefore on the quality of life and ecosystems, are nitrogen oxides (NO2 and NOx), sulfur dioxide (SO2), carbon monoxide (CO) , ozone (O3), particulate matter (including metals, secondary organic and inorganic compounds) and volatile organic compounds (VOCs). PM10 are solid and liquid particles of very small organic or inorganic substances, with a diameter between 2.5 and 10 µm (one thousandth of a millimeter). PM is the acronym for "particulate matter" and the 10 indicates the maximum particle size. Among these sizes we find dust, soot, cement, pollen and metals such as nickel, cadmium, arsenic and lead. This indicator shows the differences in the average annual concentration of PM10 emissions based on the modeling of the annual PM10 averages published by the General Directorate of Environmental Quality and Climate Change.
