Iran imports nearly 55,000 tons of asbestos per year, and 95% of that is used in the construction injury, including asbestos cement plants. Kakooei and Normohammadi studied the demolition of 13 houses in Tehran, Iran to determine whether the demolition of homes where asbestos-containing construction materials were used would affect the ambient air.
The homes demolished were built before 1975 and were demolished between April 2010 and June 2011. The homes were demolished using hand tools or simple electrically or pneumatically powered tools. Each demolition site required the work of 3-5 persons, took 6 days to demolish and 1-2 weeks to remove debris. There were no wet-down methods used during the demolition.
Personal air samples were collected and evaluated, as well as bulk samples on the cement sheets, thermal insulation and chimney pipes contained in the houses. The bulk samples revealed chrysotile fibers in the construction materials. The personal air samples showed that the exposure was greater during roof demolition than during wall demolition. The authors estimated that the increase in exposure during roof demolition was due to the greater degree of disruptions of asbestos based sheet and pipes present on the surfaces of the houses.
