English Abstract
Background: Few studies have been carried out on acute effects of cement dust exposure.
This study is conducted to investigate the associations between current "total" dust exposure and acute respiratory symptoms and lung function among cement factory workers.
Aim: To investigate the level of PM air pollution in cement plants, and their impacts on respiratory system health, pulmonary function and arterial blood gases for cement plants workers.
Material and Methods: Case-control study was conducted during the period from August to October, 2014.
on all cement plants at Middle Gaza Governorates.
100 individuals participated, case (exposed) and control (non exposed) groups contain 50, 50 respectively.
All participants were subjected to questionnaire, lung function measuring, and arterial blood gases.
Results: Results showed that an average particulate matter from 106.3 to 143.3, which is about more than 4 times higher than the particulate matter (PM2.5) existing standard of 35 μg/m3 also an average particulate matter from 615 to 656, which is about more than 4 times higher than the particulate matter (PM10) existing standard of 150 μg/m3.
As well as, it showed clear links between PM exposure and respiratory health, pulmonary function and arterial blood gases among exposed group.
Cough, dyspnea and sputum buildup were more common among the exposed group 88%, 86%, and 79.5% respectively, the non exposed group 6%, 8%, and sputum do not buildup in the control group, respectively.
Statistical analysis showed that there is sufficient evidence to conclude that mean of pH and PaCO2 is significantly different between case group and control group which confirmed that mean of pH and pCO2 for case group is significantly greater than that for control group.
Furthermore, the mean of FEV1/ FVC (%) for control group is significantly greater than that for FEV1/ FVC (%) for case group Conclusions: PM2.5_10 concentration levels in cement plants much higher than the existing standard.
Occupational exposure to PM leads to higher prevalence of respiratory symptoms, decrease lung function, and increasing pH and pCO2.
Recommendations: Environmental and engineering control of cement dust emissions, protective techniques, procedures, measures and equipment and periodic medical examinations.
