living and attending school in an urban area exposed to cement plant emissions show a chronic bioaccumulation of toxic metals, and a signicant exposure to PM 10 pollution. Cement plants located in populous urban areas seem therefore harmful, and primary prevention policies to protect children health are needed.
Cutting and breaking concrete is hard work and often requires the use of heavy-duty power saws, jack hammers, grinders, and drills. Since concrete contains quartz, these tools throw silica dust into the air. Hazardous activities include: Cutting or drilling holes in concrete or other masonry construction materials with rotary hammers, saws, and ...

Portland cement is a light grey powder that poses little immediate hazard. A single short-term exposure to the dry powder is not likely to cause serious harm. However, exposure of sufficient duration to wet Portland cement can cause serious, potentially irreversible tissue (skin or eye) destruction in the form of chemical (caustic) burns.
Cement Manufacturing Enforcement Initiative. The cement manufacturing industry was an EPA New Source Review/Prevention of Significant Deterioration (NSR/PSD) national enforcement initiative in fiscal years 2008-2010 and was continued as a Reducing Air Pollution from the Largest Sources national enforcement initiative for fiscal years 2011-2013.
The main component of cement is clinker, which is produced from raw materials, such as limestone and clay. [8]. Limestone supplies CaCO 3 for the cement production. Silica, alumina, and iron are considered to be other raw materials. The lime stone used for cement manufacturing contains 75-90 % of CaCo 3 and remainder is MgCo 3
