Large parts of New South Wales and the ACT have been blanketed in dust after a cool change blew clouds of fine particles over eastern Australia, causing a sharp drop in air quality.
It directly kills organisms that live or feed on the seafloor, including sea turtles, and it stirs up clouds of fine particles, which can suffocate fish by clogging their gills.
Offshore sand dredging has been described as "submerged, open-pit strip mining". It directly kills organisms that live or feed on the seafloor, including sea turtles, and it stirs up clouds of fine particles, which can suffocate fish by clogging their gills.
A cloud of fine dust explodes into the room from the ceiling.
It results in the formation of a cloud of fine molten droplets, ejected at high-velocity.
In urban settings, diesel exhaust is a prominent source of fine particles (U.S. EPA 2002).
This study suggests an effect of fine particles on lung function of COPD patients.
On these, the nymph spreads an inner layer of fine particles and an outer layer of coarser particles.
The amount of fine particles in the aerosol cloud is directly proportional to the square root of the pressure as ethanol concentration increases, the vapor pressure of the solution decreases; hence, the number of fine particles also decreases.
As fine grinding is needed, then the recovery of fine particles becomes a challenge.
The surrounding air passes through a small, circular cloth filter before being blown out the top, with around half of fine particles and 70percentt of larger, coarse particles removed, according to the company's press materials.
