Mineralogical Study of Respirable Dust in Artisanal SmallScale Quarries of Misisi Compound, Lusaka, Zambia

Misisi compound in Lusaka is characterized by artisanal small scale quarrying activities which are often dusty nature and prone to hazards. This study reports respirable dust concentration the mineralogical composition of rocks workplace. Dust sampling was carried out with help gravimetric samplers at five quarries. Respirable samples were collected during digging, chiselling, crushing, loading sites. The results sampled indicated high levels all quarry crushing For example, based on Time Weighted Average (TWA), site recorded as 12.75 mg/m3 quarry#1 compared Maximum Allowable Concentration (MAC) 5 Occupational Safety Health Administration (OSHA). testing analyses revealed that marble common rock type being mined most ASMs studied area. Based point count data analysis, contained 98% CaCO3 2% SiO2.
