Measurements of airborne asbestos fibres during refurbishing
Open accessAbstract
Although the use of asbestos fibres in building materials has been prohibited in Norway since 1985, asbestos-containing materials (ACMs) are still found in many buildings. Lack of knowledge and awareness of these materials may lead to exposure during refurbishing. The aim of this study was to investigate the airborne fibre concentration and classify fibres found during the abatement of various ACMs. The release of fibres during short-term work tasks, such as drilling and sawing, was also investigated. Parallel air samples were collected during asbestos abetment of different building materials and analysed with scanning electron microscope (SEM) and phase-contrast microscope (PCM), respectively. Material samples were analysed with SEM. A real-time fibre monitor was used to measure asbestos during short-term work. The highest fibre concentrations were measured for samples collected during the removal of asbestos insulating boards (1.5–4.5 fibres/cm3 [f/cm3]), and the numbers were relatively similar for SEM and PCM. A large difference in asbestos concentrations was found between SEM and PCM when analysing floor materials, which were probably caused by a high number of gypsum fibres that the PCM operator counted. Thin fibres (<0.2 µm in width) were included in the SEM count and constituted up to 50% of the total fibre concentration for the asbestos cement materials. The presence of other inorganic and organic fibres on these samples probably led to similar results between SEM and PCM. Short-term work led to peak concentrations above 30 f/cm3.

TL;DR
This study measured airborne asbestos fibres during refurbishing/abatement of various asbestos-containing materials using parallel SEM and PCM sampling, plus a real-time fibre monitor for short-term tasks. The highest concentrations occurred during removal of asbestos insulating boards, and thin fibres (<0.2 µm) made up a large share of asbestos cement releases.
Key findings
- Removal of asbestos insulating boards produced the highest personal asbestos concentrations: median 2.6 f/cm³, range 1.5–4.5 f/cm³; SEM and PCM results were relatively similar (R² = 0.94 for SEM:PCM and 0.93 for SEM+<0.2:PCM).
- For asbestos cement exterior wall/roof removal, personal asbestos medians ranged from 0.01 to 0.2 f/cm³; thin fibres (<0.2 µm) constituted up to 50% of the total fibre concentration, and the SEM+<0.2 vs PCM slope was 1.0 versus 0.72 for SEM vs PCM.
- During indoor floor removal, all SEM asbestos samples were below LOD (0.04 f/cm³), while parallel PCM samples ranged from 0.4 to 2.1 f/cm³, probably because gypsum/calcium sulphate fibres were counted by the PCM operator.
- Short-term drilling or bayonet sawing on roof slate shingles and other ACMs produced peak real-time fibre concentrations above 30 f/cm³; breaking or friction tasks gave peaks around 1.0 f/cm³.
Methods
- Personal and stationary air samples were collected during abatement of interior ACMs (asbestos insulating boards, pipe insulation, vinyl tiles, corkboard) and exterior asbestos cement materials (wall shingles, corrugated roof sheets, slate shingles). A total of 57 SEM air samples were collected (41 personal, 16 stationary); 11 were rejected for overloading, leaving 35 personal and 11 stationary samples, with 27 parallel SEM/PCM samples.
- SEM-EDX followed ISO 14966:2019 at 2000×, counting fibres >5 µm, diameter ≥0.2 µm, and length/diameter ≥3; thin fibres (<0.2 µm) were counted separately. PCM samples were analysed by NIOSH 7400. Material samples were analysed by SEM-EDX, and a real-time Fibre Monitor 7400 calibrated for chrysotile measured short-term work tasks.
Limitations
- Stated: enclosed negative-pressure areas may underestimate fibre concentrations, especially stationary samples collected 2–3 m from the activity; the fibre monitor was calibrated for chrysotile and may have counted non-asbestos fibres; SEM at 2000× may miss short fibres <0.5 µm if covered by particles; several floor and corkboard samples were rejected due to overloading; material fibre content was not quantified.
- Evident: several exposure categories had very small sample sizes (e.g., n = 1 for pipe removal, cleaning, and grinding; n = 2–3 for some floor/cork tasks), and no TEM confirmation was used, while organic fibres were removed by ashing and therefore not characterized in the SEM counts.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
