Find out about fine particulate matter, its sources and health risks.
Fine particulate matter (PM2,5) is responsible for significant negative impacts on human health.
Note: Facility-reported fine particulate matter emissions represent 3% of total national fine particulate matter emissions.
Indicator: Air health indicator—Ozone and fine particulate matter
In one aspect, the fines are lime fines or ground asphalt pavement fines.
The carbonaceous fines may be coal or charcoal fines or mixtures thereof.
Optionally, the fines can be mineral or rock fines as described herein.
The fibre layer filters fines and other fine particles from the white water.
A method is provided for the treatment of water containing micro-algae wherein the water is contacted with carbonaceous fines to adsorb micro- algae onto particles of the carbonaceous fines.
The above fine particles or first fine particles are ceramic particles or metal particles.
The above fine-particle-form substance is selected from one kind of inorganic fine particles and organic fine particles.
Those fine particles may further include fine iron(III) oxide particles.
The average diameter of the first fine particles is larger than that of the second fine particles.
Second fine particles are resin particles or metal particles.
The display medium particles comprise mother particles, child particles, and fine particles.
Fine particles in a slurry are then added, causing the fine particles to collide and stick to the emulsion particles.

Small particle compositions are provided.
The coarse and fine particles are separated from one another.
The composition is in the form of fine particles of an aqueous gel containing the water and gelling agent, the surfaces of which fine particles are coated with a coating of the finely particulate hydrophobic silica.
Fine particles in bubbles or bubbles themselves may be employed in place of the fine particles (9).
The specific fine particles (33) are organic or inorganic fine particles having an oil absorption of 250(g/100g), and silica is particularly preferably used for such specific fine particles.
A crosslinked fine particle dispersion of the present invention contains crosslinked fine particles, a surfactant and a basic substance.
The invention provides a fine particulate flux.
