Emissions of VOC’s, NOx and SOx, what is their meaning? VOCs Organic compounds are chemicals that contain carbon and are found in all living elements.
Volatile organic compounds, also called VOCs, are easily converted to vapors or gases. Along with carbon, they contain elements such as hydrogen, oxygen, fluorine, chlorine, bromine, sulfur, or nitrogen.
VOCs are released by burning fuels, such as gasoline, wood, coal, or natural gas. They are also released by solvents, paints and other products used and stored.
NOxs Nitrogen oxides are a group of chemical compounds. Separately, the oxygen and nitrogen forming them are harmless gases present in the air we breathe, but when they combine, several compounds arise that can be very harmful to health.
SOxs Sulfur oxides cause damage to many types of materials, directly or indirectly: in addition to humidity and temperature, a high content of SOx in the air accelerates the corrosion of metals such as carbon steel, zinc, galvanized steel, composites copper, nickel and aluminum. Specifically, correlations have been observed between corrosion rates in metals and concentrations of SO2 in the atmosphere, with higher values in industrialized areas.
