Industrial activities play a key role in the economic wellbeing of a country but they usually involve processes with a more or less profound environmental impact, including emission of pollutants. Among them, much attention has been given to airborne particulate matter (PM) whose exposure is ubiquitous and linked with several adverse health effects mainly due to its size and chemical composition.
regulate your operation. Many districts have Fugitive Dust Rules, which prohibits the transport of dust off your property and requires you to "take every reasonable precaution to minimize emissions." Other districts may use the State Nuisance law (above) or the Visible Emissions/Opacity rule (see following page) to regulate fugitive dust emissions.

Calera takes captured CO2, mostly from utility plants, and combines it with an alkalinity solution and calcium in the form of carbide residue to convert the CO2 to calcium carbonate and water.
1. Introduction. Atmospheric dust is a major source of pollution, especially in dry climates. Mineral dust from industrial activities is a source of heavy metals, many of which are known to be toxic (Gbadebo and Bankole, 2007) dustrial production of cement is prominent among industrial activities as a major emitter of noise, gas and particulate matter (Farmer, 1993).
What are the Effects of Dust on the Lungs? CLOSE ALL. What are the lungs? Then the macrophages, in a way which is not well understood, reach the part of the airways that is covered by cilia. The wavelike motions of the cilia move the macrophages which contain dust to the throat, where they are spat out or swallowed.

Cement and cementbased products can harm the skin in a number of ways. Wet cement is highly alkaline in nature. A serious burn or ulcer can rapidly develop if it is trapped against the skin. In extreme cases, these burns may need a skin graft or cause a limb to be amputated. Cement can also cause chemical burns to the eyes.
