UK and EU Air Quality Limits - Defra, UK

Limit values are set for individual pollutants and are made up of a concentration value, an averaging time over which it is to be measured, the number of exceedances allowed per year, if any, and a date by which it must be achieved. Some pollutants have more than one limit value covering different endpoints or averaging times. Target values – are used in some EU Directives and are set out in ...

Ozone and NO2 sensors | Details |

The ozone sensor voltage changes by mV for each 20ppb, while the NO2 sensor voltage changes by mV for each 20ppb change. Looking at the NO2 sensor. The output range is 0-3V. The minimum number of ADC steps needs to be 3000 mV/ mV = 13464 steps. It is quick to determine that a 12 bit ADC with 4096 steps is not capable of delivering this resolution.

What is an Air Quality Index (AQI)?

Our solutions Sensor Fleets ... benzene is carcinogenic from concentrations as low as 1 µg / m3, but ozone does not begin to have significant effects until 100 µg / m3! An AQI brings together the concentration values (expressed in µg / m3) of all these different pollutants in relation to the impact they have on health. Thus, the higher the value of the AQI, the more polluted the air and the ...

Ozone | American Lung Association

20/04/2020· Based on that review, EPA strengthened the official limit on ozone, called the National Ambient Air Quality Standard, in 2015. However, new research provides evidence that ozone can cause serious harm even at much lower levels. In a 2017 scientific paper, researchers provided further evidence in a nationwide study that older adults faced a higher risk of premature death even when levels of ...
