Particulate matter and the health effects on human living lung cells

• Predominant sources of personal particulate matter exposure are residential indoor and road-traffic or soil-borne outdoor respirable particles. Candles are an important source of indoor particulate matter. Therefore a pilot study was conducted in a specially built research facility for a fixed period of time. Fine and ultrafine particle concentrations were continuously sampled and the likelihood for potential health effects was studied using the CULTEX® system in which human lung cells were directly exposed to air samples. A high concentration of ultrafine particles was registered during the candle burning; a control condition recorded a much lower concentration and larger particle diameters. First results indicate that unhealthy situations due to candle burning in the indoor environment are very well possible.
