Sulfur Dioxide-18O2 has been used:

  • as an isotope indicator during biomedical research;
  • when setting up large-scale environmental studies;

For example, the use of sulfur dioxide labeled with the Oxygen-18 isotope makes it possible to determine the source of acid pollution after moving the cloud for many hundreds of kilometers.

Thus, Oxygen-18 is extremely successfully used to solve extremely relevant programs in the field of healthcare, ecology, and fundamental sciences.
