PERILOUS PARTICLES

PM2.5 are fine particles emitted by cars, trucks and buses, as well as construction equipment and locomotives. They also result from the burning of fuels such as wood, heating oil or coal, and from blazes such as forest and grass fires. Fine particles are also emitted from power plants. PM2.5 refers to the diameter of dust particles, equivalent to 1/20 of a human hair, enabling the dust to penetrate deep into lung passageways and enter the bloodstream, causing serious cardiovascular problems.
