You may know recent air pollution research and regulation has focused on PM 2.5 – the very tiny particles less than 2.5 micrometers, that can enter your bloodstream after you breathe them in. It turns out, a lot of the PM 2.5 mass in Fairbanks’s winter air is made of hydroxymethanesulfonate or HMS.
Researchers stumbled on to the new compound when sampling air in Fairbanks and North Pole in 2019 as part of the Alaska Pollution and Chemical Analysis project, or ALPACA.
Jingqiu (Jing-Chew) Mao teaches Chemistry at UAF and is a researcher at the Geophysical Institute.
“The unique thing of this project is that this really tells us there’s a chemical reaction happening in the air. That could really tell us a lot more information about what’s happening in Fairbanks’ winter, by studying this compound.”

Over the course of 2019 and 2020, a handful of fires burned in the tundra of Siberia, releasing stores of carbon similar to the entire annual emissions of France. As the Arctic continues to warm, similar fires are likely to become more common: lighting, one of the few firestarters in the far north, is becoming more common.
According to research published yesterday in Nature Climate Change, by the end of this century, lightning will be about twice as likely in the Arctic if greenhouse gas emissions continue as usual.
Edited By MARY KAUFFMAN - Today, Senator Bill Wielechowski (D-Anchorage) introduced Senate Joint Resolution 12, joining others in urging the United States Congress to remove the Windfall Elimination Provision and Government Pension Offset clauses from the United States Social Security Act.
Both provisions affect the calculation of the Social Security benefits for individuals who also receive a state pension or one from a political subdivision. The Windfall Elimination Provision applies to direct public employees while the Government Pension Offset reduces benefits of spouses and survivors who are public employees – both of which cut benefits up to hundreds of dollars per month.
