2024 No Toxicity of airborne dust as an indicator of moisture problems in school buildings https://pubmed.ncbi.nlm.nih.gov/28330428/ Tirkonnen, Jenni Europe Review Teachers Students Particulate Matter (PM) Respiratory symptoms Indoor air Moisture damage Particulate matter (PM) School Toxicity In vitro PM samples from 8 schools were tested in vitro using macrophage assays. Teachers in moisture-damaged schools reported more respiratory symptoms. While raw PM toxicity did not differ, particle-adjusted toxicity was higher in damaged schools, warranting refinement. 2017
