Pulmonary effects of inhaled ultrafine particles

Urban particles consist of three modes: ultrafine particles, accumulation mode particles (which together form the fine particle mode) and coarse mode particles. Ultrafine particles (those of < 0.1 micron diameter) contribute very little to the overall mass, but are very high in number, which in episodic events can reach several hundred thousand/cm3 in the urban air.

Air Purification

 · Ultra-fine Particle Filtration. Ultrafine particles penetrate deep in the lungs and are small enough to enter the cells in the body and end up in the bloodstream, potentially causing heart and brain diseases. Children, elderly people and people with lung problems like asthma are especially vulnerable to ultrafine particle air pollution.

However, the smaller PM2.5 particles which fall into the FINE size range (0.5 – 2.5 microns) are: Sufficiently small particles of a few microns or less in diameter which can actually bypass the para-cellular (between the cells) junctions of the epithelial cells in the lung air sacs, which means they can go deep enough into the human respiratory system to pass DIRECTLY into the bloodstream.

Ultrafine particles in cities

 · Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an acknowledged risk to human health. Globally, the major source for urban outdoor UFP concentrations is motor traffic. Ongoing trends towards urbanisation and expansion of road traffic are anticipated to further increase population exposure to UFPs.

Glossary: Fine particles

Fine particles are largely formed from gases. Ultrafine particles are formed by nucleation, which is the initial stage in which gas becomes a particle. These particles can grow up to a size of 1µm either through condensation, when additional gas condensates on the particles, or through coagulation, when two or more particles combine to form a larger particle.
