Results of Asbestos Survey in Air Environment
Last updated on February 28, 2025.
The Institute for Environmental Science conducts a survey on the concentration of asbestos fibers in the atmospheric environment.
On this page, we will inform you of the survey results.
For an overview of the survey, see the survey page on air and water environment.
The latest asbestos concentration survey results in 18 wards in the city
The range of fiber count concentrations at each point over the last three years was non-detected (less than 0.025) to 0.14 bottles / liter.
The results of this survey were sufficiently low compared to the number of fibers (1 fiber / L to less than 10 fibers / L), which is considered to be so low that health risks could not be detected in the WHO Environmental Health Criteria, so it is not a problematic level.
