Pulverized particulate matter ejected by volcanic eruption.
Fine particulate matter is linked to respiratory ailments, heart disease, stroke and premature death.
Suitable for containing fibrous or fine suspension of solid particles and the solid, particulate control.
The 2005 AQG set for the first time a guideline value for particulate matter (PM).
Most biological particulate filters remove particle sizes as small as 0.3 microns.
The Clean Air Act mandates the EPA to regulate harmful pollutants such as particulate matter and ozone.
In a gas mask designed to guard against a biological threat, a very fine particulate filter is useful.
A recent study by London's Queen Mary University linked particulate matter exposure to pneumonia, particularly among children.
Scientists have known for a long time that aerosols such as soot, dust and other small particulate matter, alter cloud density and the radiative balance of the atmosphere.
More generally, small particulate matter and other pollutants in indoor smoke inflame the airways and lungs, impairing immune response and reducing the oxygen-carrying capacity of the blood.
EPA primarily curbs particulate air pollution by limiting primary aerosol emissions from diesel exhaust, he notes, so "controlling particles may not be sufficient."
The Guidelines indicate that by reducing particulate matter (PM10) pollution from 70 to 20 micrograms per cubic metre, we can cut air quality related deaths by around 15%.
Other threats from the Gulf oil spill include particulate matter generated by burning oil floating on the surface and from the large amount of chemical dispersants used.
Measuring the health effects of particulate pollution is a tricky business — generally speaking, the smaller the particle, the more easily it can get inside your lungs and into your bloodstream.
Under the Air Pollution Control Ordinance" the owner or occupier of any premise is required to control the emission of air pollutants such as odour, VOC, particulate oily fume and gaseous substance into the atmosphere.
