Assessing toxicity of PM2.5 from indoor sources and during exposure in private homes
(2024) 18th International Conference on Indoor Air Quality and Climate, INDOOR AIR 2024- Abstract
Toxicological testing in mice was conducted on PM2.5 particles from stressed burning of two types of candles (white and blue) and on PM2.5 collected indoor and outdoor of fifteen occupied homes in southern Sweden. As an indicator of toxicity, the ability to generate Reactive Oxygen Species (ROS) was also assessed for all pooled samples: candle white, candle blue, indoor, and outdoor. Higher toxicity of indoor particles and from white candles in comparison to outdoor ones highlight the need for studies assessing toxicity of particles from indoor sources and mixtures that we are exposed to while indoors. ROS formation potential can be an interesting option to screen particles for its toxicity but the sensitivity of... (More)
Toxicological testing in mice was conducted on PM2.5 particles from stressed burning of two types of candles (white and blue) and on PM2.5 collected indoor and outdoor of fifteen occupied homes in southern Sweden. As an indicator of toxicity, the ability to generate Reactive Oxygen Species (ROS) was also assessed for all pooled samples: candle white, candle blue, indoor, and outdoor. Higher toxicity of indoor particles and from white candles in comparison to outdoor ones highlight the need for studies assessing toxicity of particles from indoor sources and mixtures that we are exposed to while indoors. ROS formation potential can be an interesting option to screen particles for its toxicity but the sensitivity of different assays to specific compounds indicates that a range of assays is needed for toxicity screening.
