In 2018 air quality levels were reaching a “red” alert status. It is the sharp rise in the concentrations of the microscopic particulate matter PM2.5 which is most troublesome as it causes most breathing and heart problems and is attributed with over 9 per cent of deaths of Italians over ...
Cork and Waterford, it can be seen that some patterns start to emerge, regarding the levels of PM2.5 being picked up on. In fact, this pattern seemed to be universal for the whole of Ireland, with many of its worst readings and poorest air quality coming in on the same months of the...
3). This variability suggests that there might be a slight change in pollutant concentration based on an improvement of local air quality during this year, but that the change might be minor compared to the temporal variation observed. Our study is not the first to observe temporal variability ...
On January 15, 2013, the Environmental Protection Agency (EPA) published a final rule revising the National Ambient Air Quality Standard (NAAQS) for particulate matter (PM). The revised air quality standards were completed pursuant to the Clean Air Act (CAA) and, in part, in response to a ...

the value, the higher the level and category, and the darker the color of the representation, the more serious the air pollution condition is and the greater the health risk to human beings, and it is suitable for indicating the short-term air quality condition and change trend of a city....
In each station, air quality parameters were measured by Particulate matter (PM) concentrations According to the time-dependent change of PM10concentrations measured at Bursa (Soganlı) station, the annual average limit value (44 μg/m3) given in the Air Quality Assessment and Management Regulati...
Similar to other countries, the results of the studies in the UK have shown variations in the impacts of lockdown on air quality, especially on particulate matter (PM). For instance, Jephcote et al. [28] reported that the PM levels, during and after the lockdown, did not change ...
