Carbon emissions, it turns out, are not the only enemy of the environment: fine particulates suspended in the air are the new nemesis.

Record densities of fine particulates were measured in the city.

Sand applied to icy roads can be ground up by traffic into fine particulates and contribute to air pollution.

Respirable and fine particulates will also be monitored, but less stringently due to their more pronounced health impact.

They are one of the most efficient and cost effective types of dust collectors available and can achieve a collection efficiency of more than 99% for very fine particulates.
