Increase in interleukin-6 and fibrinogen after exposure to dust in tunnel construction workers.
OBJECTIVES To see if there is any change in blood concentrations of interleukin-6 (IL-6) and fibrinogen during a working shift in tunnel construction workers. METHODS 12 Tunnel construction workers were followed up during a 24 hours period after returning from a 9 day work free period. The first blood sample was taken on Monday afternoon before starting the shift. Another was taken around mid...
متن کاملEvaluation of respiratory system in textile-dyeing workers
Background :Despite the presence of many textile and dyeing plants in Iran, we couldn’t find similar studies in this country. Forthermore, considering progress in the dyeing process and engineering controls, assessment of respiratory system is important for these workers. The present study was performed to evaluate the respiratory system in dyeing workers. Methods : In a cross-sectional stu...
متن کاملCumulative exposure to dust and gases as determinants of lung function decline in tunnel construction workers.
AIMS To study the relation between lung function decrease and cumulative exposure to dust and gases in tunnel construction workers. METHODS A total of 651 male construction workers (drill and blast workers, tunnel concrete workers, shotcreting operators, and tunnel boring machine workers) were followed up by spirometric measurements in 1989-2002 for an average of six years. Outdoor concrete w...
متن کاملMortality among migrant tunnel workers.
To clarify the mortality pattern of migrant tunnel workers, a retrospective cohort study was conducted in the southern part of Oita Prefecture, which is well known as a source area for tunnel workers. This study was made on 1,078 tunnel workers and 943 non-tunnel workers who were observed for 8 years and 6 months from January 1975 to June 1983. The overall SMR of tunnel workers was 162 which wa...
متن کاملTunnel boring machine positioning automation in tunnel construction
Purpose Tunnel construction using a tunnel boring machine (TBM) entails precise machine positioning and guidance in the underground space. In contrast to traditional laser-based machine guidance solutions, the proposed research aims to develop an automation alternative to facilitate TBMguidance and as-built tunnel alignment survey during tunnelling operations. Method A fully automated system is...
