SUMMARY: Exposure to cement dust has been linked to lung function impairment. However, there are few such studies in Nigeria. The main aim of this study was to assess the post-work Peak Expiratory Flow Rate (PEFR) of workers in a cement company. Sixty workers in a cement factory were randomly selected; thirty were regarded as workers exposed to cement dust and the remaining as unexposed workers...

In cement plant, since all processes are chemical and irreversible, monitoring and control is a critical factor. If the process is not controlled at any stage, the final product can be damaged or lost. Thus, in such environments, considering the quality of the product at each state is essential. Also, to control the process, communication among different parts of production line is essential. T...

The relation between exposure to cement dust and cancer was examined in a population of 546 cement workers and a reference population of 858 randomly sampled men of similar age and area of residence. In 1974 all men gave lifelong occupational and smoking histories; information on incidence of cancer in the period 1974-85 was obtained from the Danish Cancer Registry. No increased risk of overall...

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...

Study was carried out to assess the impact of cement dust on some selected plant species around industrial area. Deposition effect of cement dust on pigmentation was studied in Azadirachta indica, Pongamia pinnata, Delonix regia, Polyalthia longifolia and Ficus religiosa. Sampling was done about 500 meter distance difference from the cement industry and measurements were taken for all the plant...

OBJECTIVE to identify the association between the exposure of workers to inorganic dust in a quarry and a cement factory and pulmonary diseases. METHODS a transverse study on data from 32 quarry workers (QWs) and 57 cement production line workers (CFWs) to inorganic-dust exposure was performed. Pulmonary function tests and chest X ray were done in both groups. RESULTS there were differences...
