@dordor14, I hope you saw the helpful posts from @craigcraig and @parrot53. I found this related study:

- Association between air pollution and transplant outcomes in kidney transplant recipients: a systematic review and meta-analysis https://pmc.ncbi.nlm.nih.gov/articles/PMC12451696/

Did you ask your transplant about guidelines for transplant recipients and monitoring air quality? And did you manage to get out of helping to clean the garage? 😉
