An Airborne Dust Pollution Monitor
Journal of Optics, 1979The paper describes an electrooptical instrument for monitoring the atmospheric pollution due to dust, based on the scattering phenomena. A so called ‘aerosol’ is formed by a sampling tube, driven by a cosntant delivery air-suction pump. The sampling tube is placed before a collimating light source and the scattered light is transmitted through an ...

2011 IEEE-IAS/PCA 53rd Cement Industry Technical Conference, 2011
The cement and mineral processing Industries are currently experiencing immense pressures to greatly reduce and eliminate their pollutants, especially their uncontrolled fugitive dust emissions. Environmental groups and public opinion are consistently championing the need to increase control over industry.

Publications of the Astronomical Society of the Pacific, 1991
A model for the prediction of the brightness of the night sky due to man-made light pollution by the addition of an ozone layer is refined by the use of a more accurate representation of the atmospheric molecular density variation as a function of height, and by using a better mathematical representation of the scattering angular function of aerosols ...

Dust Pollution in Open Field Development
Ecology and Industry of Russia, 2018Regions of extraction of mineral raw materials are characterized by the proximity of powerful mining production with intensive agricultural production within the framework of the natural and man-made system. Around the quarries of open development of deposits formed a stable zone of dusting, which violates the process of self-regulation of the natural ...

Some developments in dust pollution measurement
Atmospheric Environment (1967), 1967Abstract The measurement of dust emission is considered in relation to public complaint. At least two measurements are required—ideally these should be dust amount and dust grading. No viable instruments exist to measure dust amount or dust grading continuously, and in practice it is best to use an instrument to record the optical density of the flue

Epidemiology, 2008
Particulate matter (PM10) air pollution is associated with respiratory and cardiovascular morbidity, and mortality. A recent systematic review pointed toward the fine particle fraction (PM2.5) rather than the coarse fraction (PM2.5-10) 2.5 and PM2.5-10as being responsible for increased death rates.

Environment Effects - Dust Pollution and Soil Protection
Applied Mechanics and Materials, 2016Human activities have a considerable effect upon the development of all components of the natural environment. The activity of construction represents a considerable influence upon the environment, with its significance growing with the rate of urbanisation.

Experience with C.E.R.L. dust pollution gauge
Atmospheric Environment (1967), 1967Abstract The C.E.R.L. dust pollution gauge, with its directional properties, as devised by Lucas and Moore of the Central Electricity Research Laboratories, has been found a valuable instrument. The difference in climate between Western Australia and the U.K.

Dust pollution and control with leather waste
Environmental Chemistry Letters, 2017Dust is a serious worldwide pollution, notably for nanoscale particles that are both toxic and difficult to control. Dust suppression can be done by adsorption on solid wastes, such as collagen from by-products of leather manufacturing. Here we review dust pollution and dust control, notably using collagen degradation products.
