Asbestos Survey Results in Atmospheric Environment
Last Updated February 21, 2024
The Institute of Environmental Science conducts a survey on the concentration of asbestos fibers in atmospheric environments.
On this page, we will inform you of the survey results.
For an overview of the survey, please see the page on the Atmospheric and Water Environments.
Most recent asbestos concentration survey results in 18 wards of the city
The range of fiber concentrations at each point in the last three years was undetected (less than 0.025) to 0.15 bottles / liter.
The results of this survey were sufficiently low compared to the concentration of fibers (1 tube / L to less than 10 fibers / L), which is considered to be so low that health risks cannot be detected in the WHO's Environmental Health Criteria.
