How do you test the air quality outdoors, especially in cities. Please use scientific explanation and included were u got the information. thanx:)
One of the most well-used devices in air quality monitoring is the passive sampler, because they are relatively cheap and easy to use with no utilities needed. This makes them desirable in rural areas. They measure cumulative exposures to specified contaminants like NOx and SO2.
Air quality is a multidisciplinary thing, drawing from expertise in a number of sciences, the most obvious being chemistry and meteorology. For example, this Canadian company described in the reference uses atmospheric scientists, meteorologists and engineers for air quality testing and reporting. Their webpage goes into greater detail.
