cement dust exposure is associated with increased respiratory impairment. as the major occupational hazard in the cement production industry is cement particles, our aim was to more thoroughly examine the acute effects of occupational exposure to cement dust on the respiratory system. a cross-shift study was conducted in a cement factory in iran. 100 high exposed workers from production and pac...

limestone, exploited near bielawy, a town located in the kujawsko-pomorskie province ofpoland, is the main raw material in the production process in a cement plant. the dust emitted by the factory is of alkaline ph and contains such heavy metals as: cadmium (cd), lead (pb), chromium (cr) and nickel (ni). the research aims at assessing the influence of cement dust on the total content and bioava...

dust can be produced by almost all production processes in portland cement factory. dust exposure potentially can affect respiratory function. but evidence for respiratory effect of cement dust exposure has not been conclusive. in this study we assessed effect of cement dust exposure on respiratory function in a cement production factory. a respiratory symptoms questionnaire was completed and p...

Even in the 21st century, millions of people are working daily in a dusty environment. They are exposed to different types of health hazards such as fume, gases and dust, which are risk factors in developing occupational disease. Cement industry is involved in the development of structure of this advanced and modern world but generates dust during its production. Cement dust causes lung functio...

Concrete a composite material made from cement, water, fine aggregate and coarse aggregate. But present researchers are in interest of finding new cement materials by waste materials or waste products produced from industries which are harmful to environment. The present paper deals with partial replacement of cement with quarry dust and metakaolin which are having silica used as admixture for ...

ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...
