“…It applies especially to people who are not directly involved in the work with ACM, but who are within the exposure range or near the work environment. The results of "faulty works" carried out using "dry" or “DIY” techniques were reported by Brown 30 and others 36 , 37 . Other improper removal techniques were described by Dumortier 18 .…”

“…The threat of dismantling and disturbance of ACMs poses a risk of increasing the concentration of asbestos dust in the air. Based on a databases of historical workers’ exposure to asbestos dust 17 , 36 , 44 , the highest airborne fibre concentrations were registered during construction services' active handling of asbestos products. The lowest personal exposure concentrations were observed in processes that do not require the manipulation of products.…”

The study focused on old, German building types “LIPSK” and “BERLIN” used in Poland, since the 1960s in Eastern Europe. The different operations on buildings were analysed: protection and maintenance of asbestos products, asbestos removal and inadvertent damage to asbestos as a result of building renovation. Measurements of respirable (countable) asbestos fibres in the air were carried out using the PCOM + PLM method and SEM–EDS. In the case of the accidental destruction of products, initial contamination was ≈7000 f/m3. After 16 weeks from the end of the activity and 20 days of extreme ventilation, contamination decreased to about 500 f/m3. At the same time, in similar rooms, without extreme ventilation, the pollution was above 4000 f/m3. The average increase in pollution in a dozen or so similar buildings, after asbestos removal in places beyond the work zones, ranged from ≈ 1700–2700 f/m3 and lasted for one or two years. These buildings, used without ACM destruction or after product impregnation, have maintained low asbestos contamination < 300 f/m3 for more than 10–20 years. So, due to the easy release of asbestos that occurs with any ACM removal and the increased risk of occupant exposure, these works are often inappropriate for the buildings in question.

“…The Victorian Asbestos Eradication Agency stated that ambient or background air usually contains between 0.00001 and 0.0002 bers/cm 3 (VAEA, 2023). This is because the ber concentration in the air can vary widely depending on the location, characteristics, building materials, and demolition methods (Obminski et al, 2020). In Korea, airborne asbestos was detected as 0.00062 bers/cm 3 and 0.068 bers/cm 3 for urban and rural areas respectively (Lim et al, 2004).…”

“…Depending on the type of building (residential, industrial, etc) to be demolished, a detailed determination of asbestos bers reveals the exact situation of the environment. (Obminski, 2020;Zhang et al, 2021). In terms of health, it is vital to determine the amount and type of asbestos-containing materials and the status of airborne asbestos (Neitzel et al, 2020).…”

Asbestos has been used extensively in the construction industry for its superior insulation properties before its health hazards were discovered and eventually getting banned. It would not be wrong to assume all residential buildings built before the 2000s in Turkey contain asbestos. Therefore, it is important to raise awareness of the potential danger of asbestos exposure during demolition work and to identify asbestos-containing materials and ensure their safe removal and disposal. This study summarizes the efforts being made in the “Asbestos Free Demolition” EU project, which is executed to determine the residential dwellings containing asbestos in Izmir. The project included field study to determine asbestos presence in the buildings that were damaged during the 2020 earthquake. 505 bulk samples were taken from 50 buildings that would go through the demolition process. 11 buildings were found to contain asbestos. This rate corresponds to 22%. In addition to asbestos removal processes in these buildings containing asbestos, air measurements were taken from each building. The detected asbestos type was 60% chrysotile (white asbestos). The concentration of asbestos in the air is ignorable also personal exposure did not exceed the permissible exposure limit (PEL) for 0.1 fiber/cm3. Results demonstrate the findings of asbestos-containing materials and suggestions before demolition work. Also, it is expected that the database created for this study could be useful in other studies involving Turkey, where accurate statistical data related with asbestos measurements is still difficult to obtain.

“…The sample analyzes were carried out using the PCM + PLM method (phase-contrast and polarized light microscopy), which has been previously, repeatedly veri ed by electron microscopy and comparative inter-laboratory studies. The applied analysis method was described previously [22,30]. After chemically treating the lters, microscopic tests were performed, calculating the number of counted respirable bres (PCM method), identi ed as asbestos bres (PLM method).…”

Environmental pollution as a result of a vacuum deficit in the working areas during asbestos removal work.

The paper presents examples of the consequences of the lack of negative pressure in the work zone during asbestos removal. The results obtained for dust concentrations generated during these works in the work zone were relatively low compared to the literature data. This was due to the leakage of barriers restricting the work zone and the 'leakage' of dust. Therefore the asbestos content in the outdoor air in the vicinity of the renovated rooms was increasing. In the discussed cases, those works polluted the outdoor air for up to 15 m. The risk of asbestos dust content in the cleaned building outside the work area also increased. Those places often are not well controlled. Therefore, this may lead to long-term retention of asbestos dust in the facility despite the completion of the process of removing asbestos products from it. For example, non-friable asbestos- cement sheets removal in those work conditions increased contamination up to 3000 f/m3 outside the work zone. In the case of work with friable asbestos in building type “LIPSK”, contamination locally was up 21 000 f/m3. These values are above the average concentration of asbestos fibres in buildings of this type normally used and after works to correct asbestos removal (< 300–400 f/m3). Reported indoor air research results from the work zone in the case of the lack of negative pressure, without documented sampling conditions and contractor working methods, can falsely suggest a high standard of work quality.
