The canary in the gold mine – early air quality detection
The story of the canary in the gold mine is one that is an important part of British History. Similarly, this expression, once part of an important discovery, can be said as the same thing as early air quality detection. What is the history…

Future use cases for air quality data: air quality as a dimension of (re-)insurance
As part of the InterLuft project, we are envisioning future use cases of ubiquitous air quality data in our cities: This article is part of a series of visions of the future and thought experiments on how our surroundings might become more environmentally…

Do plants improve air quality?
According to an often-quoted study conducted by NASA, house plants have been found to purify the air and remove “up to 87% of the amount of toxins in the air”. Recent studies, however, have cast doubt on these statements finding that indoor…

Everything to know about Nitrogen Monoxide (NO)
Nitrogen monoxide belongs to a family (nitrogen oxides) of poisonous, highly reactive gases that form when fuel is burned at high temperatures. Nitrogen monoxide pollution is emitted by automobiles, various non-road vehicles such as boats and…

European Regulation and Limits on Air Pollution
When exposed to air pollutants in ambient air, or the air that we breathe, this can have an adverse effect on our health. The European Union (EU) policy on air quality aims to develop and implement appropriate instruments to improve air quality.…

What the color of your smog tells you about local air pollutants
Smog makes our air unclear and gives a reddish-brown haze of color over our cities. This is why smog can be used as an indicator of poor air quality. Smog can also tell you the severity of air pollutants in your area too. Read on to find out…
