This data measures the level of three different pollutants at each address. The first is PM10, or inhalable particulates, which can cause wheezing, bronchitis and reduce lung development. It also records the level of PM2.5 – fine particulates which are smaller in size and can cause asthma, respiratory inflammation and promote cancers.
The website additionally provides figures for the amount of NO2, or Nitrogen Dioxide, in the air. Long term exposure to even low levels of this toxic gas increases mortality rates and contributes to the development of asthma, and other respiratory issues.
