Carrington Air Quality

The parish council have installed an Air Quality Monitoring System on Manchester Road opposite the business park entrance. The system purchased is commonly used by many local authorities. The annual average legal limits are displayed as the maximum value in each chart.

NO2 primarily gets in the air from the burning of fuel. NO2 forms from emissions from cars, trucks and buses, power plants, and off-road equipment.

Ground level ozone(O3), is not emitted directly into the air, but is created by chemical reactions. This happens when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources chemically react in the presence of sunlight.

Nitrogen oxides (NO) are produced from fuel combustion in mobile and stationary sources. The combustion of fuel in car emit nitrogen oxides into the atmosphere (mobile source). Stationary emissions come from coal fired power plants, electric power plant boilers.

PM2.5 particles are invisible to the naked eye and small enough to pass through the lungs, into the bloodstream, and into your organs. Generally, they come from the combustion of solid and liquid fuels, through power generation, domestic heating and in-vehicle engines.

PM10 is any particulate matter in the air that include including smoke, dust, soot, salts, acids, and metals. Particulate matter can also be formed indirectly when gases emitted from motor vehicles and industries undergo chemical reactions in the atmosphere or other sources such as or domestic fireplaces


What the weather is doing can have direct effects on air quality at a given location. For example, sunshine, rain, air temperature and wind can affect the amount of air pollution present:

  • Sunshine - makes some pollutants undergo chemical reactions, producing smog.

  • Rain - washes out water-soluble pollutants and particulate matter.

  • Higher air temperatures - speed up chemical reactions in the air.

  • Wind speed, atmospheric turbulence/stability, and mixing depth - affect the dispersal and dilution of pollutants.


The PM2.5 Annual Mean Concentration target for 2040 will be 10 Β΅g m-3. The UK Government will set some interim targets to achieve this. The first will be published in January 2023 (Red line indicates the 2040 target)
