What are the major air pollution problems? Reducing emissions of inhalable particles improves public health as well as visibility.

Benzene Formaldehyde Polycyclic hydrocarbons 2)When sulfur. Strictly to the point of air pollution, and not including pollution from water, foo etc. PM stands for particulate matter (also called particle pollution ): the term for a mixture of solid particles and liquid droplets found in the air.
