total dust and asbestos concentrations during asbestos-containing materials abatement in korea
this study was performed during the abatement of two asbestos-containing materials (acm):baumlite board (cement flat board) and ceiling textile. the concentrations of total dust for personal sampling were 0.28 and 1.70 mg/m3 during baumlite board and ceiling textile abatements, respectively, when calculated with 8-hr time-weighted average (twa). the geometric mean (gm) asbestos concentrations w...

متن کاملAsbestos Presence in a Factory that Produced Asbestos-Containing Products
In 2007, research was carried out to determine the type and amount of asbestos fibers in a Croatian factory with a long history of making asbestos-containing products.Since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. In the environment, asbestos fibres are inactive and naturally resist biodegradation. In time, fibres can only be gr...
متن کاملAirborne asbestos and non-asbestos fiber concentrations in non-occupational environments in Korea.
Both airborne asbestos and non-asbestos fiber concentrations were evaluated in Korean non-occupational environments. The airborne fiber concentrations were analyzed in 96 air samples, from 48 different points, by transmission electron microscopy, with energy-dispersive X-ray analysis. The geometric means of the airborne asbestos and non-asbestos fiber concentrations were 0.62 and 67.86, and 0.3...
متن کاملThe trend in airborne asbestos concentrations at plants manufacturing asbestos-containing products in Japan.
In Japan, chrysotile is still permitted to use under the Ordinance on Prevention of Hazards due to Specified Chemical Substances. In recent years many countries have introduced a policy of prohibiting the use of asbestos, based on clinical and epidemiological studies. In light of this, it is important to evaluate the airborne asbestos concentrations in workplaces and also estimate the number of...
