...suspended particulate matter Substances smaller than about 20 microns that remain in the atmosphere for extended periods because their small mass is not immediately influenced by the force of gravity. Particulate matter smaller than 10 microns can be inhaled, and particles smaller than 2.5 microns can be inhaled and penetrate to the alveoli. ...

...fine suspended particulate matter ( FSP ) Atmospheric dust or solid particulates in emission products of combustion with an aerodynamic diameter of 2.5 microns or less (also known as PM 25 ) that remain suspended in the atmosphere. Particles of less than 2.5 mm ( PM 2.5 ) can penetrate to the alveoli and contribute to pneumoconiosis or chronic respiratory disease. ...

total suspended particles

total suspended particles  

The particulate matter that is present in the air at a given place and time.
airborne particulate

airborne particulate  

The suspended matter that exists in the atmosphere as tiny solid particles or liquid droplets. It comes from many sources, including windblown dust, emissions from industrial processes, smoke from ...
suspended solids

suspended solids  

Solids (colloidal and particulate matter such as clay, sand, and finely divided organic material) that either float on the surface of water or are suspended in it. Suspended solids can usually be ...
particulate matter

particulate matter  

Fine particles that are suspended in the atmosphere. Many are of natural origin, e.g. pollen grains, fungal spores, and volcanic dust. Others are injected into the air by human activity, e.g. ...
hearth

hearth  

The base of a furnace or fireplace. The extent to which combustion is complete and emissions contain suspended particulate matter depends on oxygen flow to the hearth. An inefficient hearth, as well ...
grit

grit  

Coarse particulate matter, generally exceeding 75 microns in size, that settles rapidly from the air in which it is suspended, e.g., as emissions from a coal-burning furnace.
seston

seston  

Particulate matter that is suspended in seawater.
settlement tank

settlement tank  

Syn: settling chamber. A container in which liquids containing suspended solids are maintained at rest for a sufficient period for the suspended solids to settle in a layer of sediment at the bottom, ...
radioactive fallout

radioactive fallout  

Suspended particulate matter from a nuclear explosion or nuclear power plant accident that disseminates radioactive material. The fallout is greatest along the path of prevailing winds, producing ...
suspension feeder

suspension feeder  

Any organism (such as sponges and corals) that feeds on particulate organic matter (including plankton) that is suspended in a water column. Also known as a filter feeder or suspensivore.
Lamb's dust-veil index

Lamb's dust-veil index  

Index, devised by H. H. Lamb, of the amount of finely divided material suspended in the atmosphere after great volcanic eruptions, and of the duration of an effective veil intercepting the Sun's ...
Air Quality Index

Air Quality Index  

An arbitrarily defined scale used by weather forecasters (e.g., in radio and television broadcasts) that assigns a score for air quality, based on the quantity of suspended particulate matter, ...
volcanic dust

volcanic dust  

Dust, ash, or other particulate matter commonly suspended in the atmosphere after volcanic eruptions. After explosive eruptions the dust may be thrown to heights of 20–30 km or more. The fall-out ...
sewage

sewage  

Waste matter from industrial and domestic sources that is dissolved or suspended in water. Raw (untreated) sewage is a pollutant. It has a high content of organic matter (notably faeces and ...
