February 25, 2019, based on a review of the full body of currently available scientific evidence and exposure/risk information, the EPA issued a decision to retain the existing primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO 2). This site provides information about sulfur dioxide and its effects. On December 21, 2020, EPA took the final step to implement the health-based national air quality standard for sulfur dioxide (SO 2) set in 2010. (1)SO2 = sulfur dioxide (2) Units of measure are in parts per million (ppm) and parts per … Researchers have found that long-term exposure to fine particulate matter is associated with an increased risk of COVID-19 death in the U.S. The NAAQS for sulfur oxides are currently set using SO 2 as the indicator of the larger group of sulfur oxides. EPA has identified or “designated”. Symptoms include wheezing, coughing and shortness of breath. (3) The 1971 final rule also included a secondary 24-hour SO 2 standard of 0.1 ppm, maximum 24-hour concentration not to be exceeded more than once per year, as a guide to be used in assessing implementation plans to achieve the annual standard.

What is SO2 and how does it get in the air? EPA approved the use of Method 8A in December 1996 for the determination of acid vapor or mist and sulfur dioxide emissions from kraft recovery furnaces. Control measures that reduce SO2 can generally be expected to reduce people’s exposures to all gaseous SOx. The other gases in the group are much less common in the atmosphere . Pacific Southwest. Smaller sources of SO2 emissions include: industrial processes such as extracting metal from ore; natural sources such as volcanoes; and locomotives, ships and other vehicles and heavy equipment that burn fuel with a high sulfur content. dioxide and sulfuric acid, the quantity of sulfur dioxide can be measured by barium-thorin titration (EPA 1995k).
