Characterization and Hazard Identification of Respirable
The dust was generated by cutting the cured cement and concrete blocks using an 18” hand-held circular saw as used in highway and building construction. concern. To our knowledge, no study to date has collected and performed size and chemical characterization of actual dust produced by cutting and grinding cement-based Abstract. Mineral dusts produced from mining activities pose a risk to human health and the surrounding environment. The particle size distribution of dust is important for determining environmental, occupational health and physiological impacts. Dust is generally thought of as particulates with a diameter of between 1 and 60 μm, but Mineral Dust Emissions at Metalliferous Mine Sites

Emission of respirable dust from stone quarrying, potential health
Mining of minerals exerts adverse pressure on different compartments of environment directly or indirectly. Air is the worst affected environmental matrix, and it can carry the harmful effect of pollutants generated from mining activity even to distant places. The present study was undertaken to estimate the emission of particulate matter (PM2.5 • Use cleaners with low toxic air pollutant and VOC content, such as water-based cleaners. • Dedicate equipment to a single product, or family of products that are similarly colored, to reduce the need for equipment cleaning between batches.

Dust Emission Monitoring in Cement Plant Mills: A Case
The phenomenon was precisely the opposite of the level of 2019. However, we can note that the months of 2019 with a slightly higher level of dust concentration in the stack of the cement mill were August, with 4.6 mg/Nm 3, October, with 5.06 mg/Nm 3, and November, with 4.54 mg/Nm 3.grinding, welding, and sanding operations that will require special consideration to control potential pollutants that could accumulate and be subject to stormwater runoff.

Despite recent global reductions in air pollutant emissions from coal, this fuel was still the dominant contributing combustible fuel type to the PM 2.5 disease burden in 20 countries, including1. Grinding and size classification to reduce the ore down to a fine particle size. 2. Leaching and adsorption to extract the precious metals from the rock. 3. Recovery of gold to produce dore bullion bars. Fig. 1 shows the gold plant under investigation.

Cement Dust an overview ScienceDirect Topics
Cement kiln dust is a fine powdery material generated as a by-product of Portland cement manufacturing and can be used to create blended concretes ( Kunal & Rajor, 2012 ). This solution helps to minimize the amount of material landfilled and the amount of clinker required in cement production.These harmful pollutants are responsible for 20% of roadside pollution.

A Review on Pollution Treatment in Cement Industrial
In various cement manufacturing, fly ash, rock spoil, and dust are generated as solid wastes. Cement bypass dust is the main solid waste in cement industries collected from the surface of the dust filter membranes. These materials contain pollutant particles with alkaline behavior (pH~11–12) and a diameter of 1 to 10 m, known as AP-42, Compilation of Air Pollutant Emissions Factors, has been published since 1972 as the primary compilation of EPA's emissions factor information. It contains emissions factors and process information for more than 200 air pollution source categories. A source category is a specific industry sector or group of similar emitting sources.AP-42: Compilation of Air Emissions Factors US EPA
