The subject study is "hot-off-the-press" and is worthy of your consideration.
This summary has PDF Link so you can read the entire report (attached below).
The Bottom Line : "These finds have important implications for guidance on source control and mitigation."
It maybe possible that this will open up a blocked avenue of RPE.
After review, I certainly welcome your comments.
Be Safe and Stay Healthy!
All My Best and Happy Holidays,
