“…The levels of building contamination during exploitation can result 11,12 in a low values as 70 -120 f / m 3 . Dust concentrations can reach there also high values in the workspace depending on the condition of the products and their destruction 13 approx. 50 000 -388 000 f / m 3 and even 9 300 000 -600 000 f / m 3 .…”

The aim of the research was measure changes asbestos dust concentration over long period of use in old building systems. Buildings from different systems during their exploitation and after asbestos removal were tested. Asbestos dust concentration decreasing in some building systems is due to air exchange and other phenomena, if there are no new active dust sources. Currently, with proper use of those buildings, average values of dust concentrations did not exceed range 300 - 400 f / m3 with a downward trend to <300 f / m3. The results of these studies were obtained with a modified optical microscopy technique and verified by SEM and TEM methods. The graphical trend of the variability contaminations allows estimate them in the future better then theoretical models. Research proves that a single measurements done in short time as an applicable obligatory immediately after the asbestos removal may not detect the hazard appearing after some time. Monitoring buildings over longer periods of time allows to detect significant changes in their contamination. In many cases the minimal air contamination undermines the desirability of removing asbestos in old buildings

“…For this reason, the ACS were set as the main ACM target in the present study. All ACS in Korea were manufactured to the Korean Standard (KS), which requires a combination of about 90% cement and 10% chrysotile [ 32 ]. Table 1 presents the industrial standard dimensions of ACS produced in Korea.…”

When asbestos containing materials (ACM) must be removed from the building before demolition, additional greenhouse gas (GHG) emissions are generated. However, precedent studies have not considered the removal of ACM from the building. The present study aimed to develop a model for estimating GHG emissions created by the ACM removal processes, specifically the removal of asbestos cement slates (ACS). The second objective was to use the new model to predict the total GHG emission produced by ACM removal in the entire country of Korea. First, an input-equipment inventory was established for each step of the ACS removal process. Second, an energy consumption database for each equipment type was established. Third, the total GHG emission contributed by each step of the process was calculated. The GHG emissions generated from the 1,142,688 ACS-containing buildings in Korea was estimated to total 23,778 tonCO2eq to 132,141 tonCO2eq. This study was meaningful in that the emissions generated by ACS removal have not been studied before. Furthermore, the study deals with additional problems that can be triggered by the presence of asbestos in building materials. The method provided in this study is expected to contribute greatly to the calculation of GHG emissions caused by ACM worldwide.

“…In Korea, slate was widely used to replace roofing materials in rural areas during the period of rapid economic growth during the 1970s and 1980s, and was commonly used in poor urban areas [ 8 ]. However, few studies have addressed the health effects of living under or near slate roofs [ 8 ], even though the surrounding asbestos concentration in ambient air might be substantial [ 11 ].…”

This study aimed to evaluate the relationship between various asbestos exposure routes and asbestos-related disorders (ARDs). The study population comprised 11,186 residents of a metropolitan city who lived near asbestos factories, shipyards, or in slate roof-dense areas. ARDs were determined from chest X-rays indicating lower lung fibrosis (LFF), pleural disease (PD), and lung masses (LMs). Of the subjects, 11.2%, 10.4%, 67.2% and 8.3% were exposed to asbestos via occupational, household, neighborhood, and slate roof routes, respectively. The odds ratio (OR) of PD from household exposure (i.e., living with asbestos-producing workers) was 1.9 (95% confidence interval: 0.9–4.2), and those of LLF and PD from neighborhood exposure, or residing near asbestos factories) for <19 or >20 years, or near a mine, were 4.1 (2.8–5.8) and 4.8 (3.4–6.7), 8.3 (5.5–12.3) and 8.0 (5.5–11.6), and 4.8 (2.7–8.5) and 9.0 (5.6–14.4), respectively. The ORs of LLF, PD, and LM among those residing in slate-dense areas were 5.5 (3.3–9.0), 8.8 (5.6–13.8), and 20.5 (10.4–40.4), respectively. Substantial proportions of citizens residing in industrialized cities have potentially been exposed to asbestos, and various exposure routes are associated with the development of ARDs. Given the limitations of this study, including potential confounders such as socioeconomic status, further research is needed.
