Effects of Exposure to Portland Cement Dust on Lung Function in Portland Cement Factory Workers in Khash, Iran
The present study was done to assess cement dust exposure and its relationship to respiratory health effects, both acute and chronic respiratory symptoms and ventilatory function impairment among Portland cement factory workers in Khash located in the south part of Iran.

| description | The present study was done to assess cement dust exposure and its
relationship to respiratory health effects, both acute and chronic
respiratory symptoms and ventilatory function impairment among Portland
cement factory workers in Khash located in the south part of Iran. A
cross-sectional study was conducted at Khash Portland cement producing
factory in Iran in 2001. A total of 170 exposed and 170 unexposed
employees were selected. Air transmitted personal respirable dust and
total dust samples were collected in a full-time (8h/day) shift. Dust
level was determined by the gravimetric method. An
interviewer-administered questionnaire was used to collect information
and history of respiratory health among workers (exposed and unexposed
to dust) and measurements of lung function were made using a spirometer
in both groups. Concentrations of personal respirable dust ranged from
3.7 mg/m3 in the kilns to 23 mg/m3 in the ore crushing area, and total
dust ranged from 15 mg/m3 in the kilns to 95 mg/m3. Cough and phlegm,
with or without shortness of breath, were significantly related to dust
concentration. Measuring pulmonary functions of workers exposed to dust
and unexposed group showed a significant decrease in vital capacity,
forced vital capacity, FEF25-75 and Forced Expiratory Volume in the
first second (P |

first second (P<0.05). Findings suggest that occupational exposure
to Portland cement dust may lead to higher prevalence of respiratory
symptoms and the reduction of ventilator capacity due to existence of
quartz in row material of cement dusts. The study revealed that cement
dust exposure is associated with acute as well as chronic respiratory
health effects. It is recommended that engineering measures must be
taken to reduce the dust level in cement factories, accompanied with
health monitoring of exposed employees.</description><identifier>ISSN: 1735-1979</identifier><language>eng</language><publisher>Iranian Association of Environmental Health (IAEH)</publisher><subject>Cement, respiratory symptoms, lung function, dust, Portland cement</subject><ispartof>Iranian journal of environmental health science & engineering, 2008-01, Vol.5 (3), p.201-206</ispartof><rights>Copyright 2008 - Tehran University of Medical Sciences Publications</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,79173</link.rule.ids></links><search><creatorcontrib>Mirzaee, R</creatorcontrib><creatorcontrib>Kebriaei, A</creatorcontrib><creatorcontrib>Hashemi, S.
