Workers in Parking and milling sections of the factory should be specifically placed on routing monitoring of exposure rate. Cr(III) is an essential mineral in human nutrition, but Cr(VI) which cement workers are exposed to is toxic .The target organ of inhaled chromium is the lung but the kidney, liver, skin and immune system may also be affected (ASTDR, Ogunbileje et al,2009), thus, workers in the milling

Analysis of Potentially Toxic Metals in Airborne Cement Dust Around Sagamu, Southwestern Nigeria: Gbadebo and Bankole: Abstract: This study analyzed the concentration levels of potentially toxic and harmful elements contained in the airborne cement dust generated in the vicinity and farther away 500 m in the conventional four cardinal directions from the West African Portland Cement

Background . Cement dust inhalation is associated with deleterious health effects. The impact of cement dust exposure on the peak expiratory flow rate (PEFR), liver function, and some serum elements in workers and residents near cement factory were assessed. Methods . Two hundred and ten subjects (50 workers, 60 residents, and 100 controls) aged 1860 years were studied.
Indoor settled harmattan dusts at seven sampling stations from the University of Agriculture Makurdi were collected between November, 2014 to March, 2015 (five months) using the wipe sampling methodology. Gravimetric measurement of the dust samples from all the sample locations revealed that dust loading within the institution during the period of assessment ranges from g/m2.
This cassette facilitates the analysis of dust on the filter and is optimized for the fieldbased silica monitoring approach. Photo by NIOSH. One anticipated outcome of this project is the adoption of the fieldbased silica monitoring approach by health and safety professionals in the mining industry in both coal and metal/nonmetal.
Airborne dusts are of particular concern because they are well known to be and cement dusts; releasing potentially harmful material to the body.) Mucociliary clearance. Hazard Prevention and Control in the Work Environment: Airborne Dust WHO/SDE/OEH/

Analysis Of Potentially Toic Metals In Airborne Cement Dust In studies with rats exposed either to antimony dust (50 mg/kg, ) or to antimony xide dust (250 mg/m, 4 hours per day for to 2 months), Belyaeva (1967) reported increased reproductive failure, fewer offspring, and damage to the reproductive tissues (ovary and uterus).
Cement is a fine, gray or white powder which is largely made up of Cement Kiln Dust (CKD), a byproduct of the final cement product, usually stored as wastes in openpits and landfills (Although, the basic constituents of cement dust are calcium (CaCO3), silicon (SiO2), aluminum (Al2O3), ferric and manganese oxides) its production produces known toxic, carcinogenic and mutagenic substances
Production of cement is achieved by wet processing method. This study investigate the concentration levels of potentially harmful toxic metals in the air and cement dust generated in the vicinity and farther away (, 500 m) in the four cardinal directions from the West African Portland Cement (WAPCO) mill, Sagamu area of southwestern Nigeria.

#0183;#32;In recent years, increasing attention has been drawn to the environmental fate of potentially toxic elements (PTEs) from wastes. PTEs refer to chemical elements including both metals and nonmetals that may potentially cause harmful effects on the organisms in the environment if present in high concentrations (Antoniadis et al., 2019a).
The results indicated that the concentration range of these toxic elements fall between and 280,000 g glt;supgt;1lt;/supgt; in the cement dust samples. Also, the concentration range of these toxic elements in 1 L of air samples varies between g glt;supgt;1lt;/supgt; and g Llt;supgt;1lt;/supgt;.
