Air quality
If you are going on a short business trip (less than a few weeks) to a city with air pollution, the risk to healthy people is low.

Air pollution can have various causes: emissions from industry and traffic combined with the weather – dry conditions and little wind, or conversely strong winds causing desert dust or particles from forest fires to create smog.
