A supportive commentary on the U.S. EPA's decision to abandon the Integrated Risk Information System (IRIS) and distribute hazard identification and dose-response assessment tasks to individual program offices:
https://www.acsh.org/news/2026/05/19/adios-iris-50131
Although IRIS has become a chokepoint, if not an actual block, on risk assessments, there is no data to show that this change will improve the speed, accuracy, or consistency of risk assessments.

A critique of the linear non-threshold model used by the U.S. EPA to assess cancer risk:

As noted in the article, this is a politically contentious topic. The author has had a long career in both the public and private sector, and does not appear to have a political agenda.

My 2cents because that’s pretty much what it’s come down to:
1) While Pundits and politicos bite their cuticles over Musk; together with US #FCC Canada ISED Mexico IFT {NoKingNorthAmerica} hire Carlos Silim Helú to oversee #satelliteinternetservice
2) US #NASA #USEPA must form a coalition with #UN n respective regulatory agencies
of Japan, UK, Europe, Australia, South Africa space programs
3) #Dem leaders must don continental army hats and send #TrumpMuskNetanyahu to the #ICC in The Hague. -
Canadian wildfires prompt air-quality alerts across five US states | The Guardian (2025-06-04)
https://www.theguardian.com/us-news/2025/jun/04/canada-wildfire-smoke-air-quality
———>> Officials in New York, New Jersey, Iowa, New Hampshire and Maine issued alerts due to smoke from fires in #Canada
>> The fires, which have been sparked by both humans and natural causes, have prompted at least 25,000 residents in three Canadian provinces to evacuate in recent days.
>> On Wednesday afternoon, a map from the US Environmental Protection Agency’s AirNow forecast showed large swaths of moderate to unhealthy air quality across the east, midwest and southern parts of the US, featuring smoke and dust.

Another potential act of malicious stupidity:
So many outstanding people in #USEPA #ORD have made advances to environmental protection. EPA has produced many valuable resources for education and research
But I guess this is another attempt to implement the ostrich principle that if we don't measure anything and don't study anything, there will be no adverse occurrences.

Maxine Joselow & Scott Dance: Why #scientists fear a second #tRump term, and what they are doing about it: Several federal agencies are working to safeguard research, including climate science, from future political meddling.
"When the union representing nearly half of Environmental Protection Agency employees approved a new contract with the federal government this month, it included an unusual provision that had nothing to do with pay, benefits or workplace flexibility: protections from political meddling into their work.
The protections, which ensure workers can report any meddling without fear of “retribution, reprisal, or retaliation,” are “a way for us to get in front of a second Trump administration and protect our workers,” said Marie Owens Powell, an EPA gas station storage tank inspector and president of American Federation of Government Employees (AFGE) Council 238."

Excited to present our ongoing work with NASA GMAO, US EPA, UNEP, and many others to develop subcity-scale forecasts for PM2.5, NO2, and ozone at AAAR today. Come check out the presentation this afternoon (Tuesday, October 3) at 3:45 in room F151! #airpollution #airquality #aaar2023 #aaar #forecast #PM25 #particulatematter #nasa #usepa #unep

Research on DIY Air Cleaners to Reduce Wildfire Smoke Indoors
Do-It-Yourself (DIY) air cleaners, made with a box fan and MERV 13 air filter, are a cost-effective method for reducing smoke concentrations.
Only use newer, certified box fans with added safety features (2012 models or newer).
Improve the effectiveness of the basic DIY air cleaner design:
👉Add a cardboard shroud (a no-cost improvement).
👉Use a thicker filter(s) (4” rather than 1”).
👉Use multiple filters (2 to 5 filter air cleaner designs).
👉Keep extra filters on hand and replace when dirty.
👉Keep track of air quality using the AirNow Fire and Smoke Map| #USEPA

Update: this doesn't meet my need, but it's REALLY cool:
If you're in the US, the EPA has a program that will loan you air quality monitors:https://www.epa.gov/air-sensor-toolbox/air-sensor-loan-programs

The #USEPA (finally) issued their final determination on gold mining in the Bristol Bay watershed, bringing and end to decades of debate. YAY!
I was a part of a review panel for their assessments about 10 years ago, and we thought we were close then to closing this door. Had the US government not swung back to reason with the election of Biden and the dem majority, this would not have happened.

#USEPA and #USArmy are finalizing a rule defining the scope of waters protected under the #CleanWaterAct. They considered the text of the relevant provisions of the Clean Water Act and the statute as a whole, the scientific record, relevant Supreme Court case law, and the agencies’ experience and technical expertise after more than 45 years of implementing the longstanding pre-2015 regulations defining “waters of the U.S.” https://www.epa.gov/wotus/revising-definition-waters-united-states
