Scope

Does the option have an effect on emissions of acidifying, eutrophying, photochemical or harmful air pollutants that might affect human health, damage crops or buildings or lead to deterioration in the environment (polluted soil or rivers etc)?[1]

Definition

From a human health perspective, the main outstanding air pollution problems are particulate matter (very small particles, which, if inhaled might cause lunge diseases), tropospheric ozone (ozone near ground level) and photochemical smog. Smog has been an important air quality issue in metropolitan areas and large cities for several decades. The accepted indicator of smog level is the concentration of ozone, which is its major constituent. In contrast to the beneficial effects of stratospheric ozone, tropospheric or ground level ozone can adversely affect human health. Ground level ozone can also have adverse effects on building materials and vegetation.[1]

A relatively small number of different pollutants (SOx, NOx, NHx, NMVOC) and some fine particulates are the main causes of environmental impacts that strongly affect ecosystems. Emissions from burning fossil fuel, e.g. sulfur (SOx) as well as nitrogen oxides (NOx) from vehicle exhaust fumes, industrial boilers and power stations, react with other gases in the atmosphere and form acids. While terrestrial eutrophication is mainly caused by ammonia (NH3) and nitrogen oxide (NOx), acidification potentials are highest for sulfur dioxide (SO2) air emissions. Through disposal via rain, air pollutants and their acids accumulate in soil and water and critical loads are exceeded in some areas. Those can then lead to irreversable destruction of the affected ecosystems.[1]
