) of 76 different air sampling filters have been characterised to be a function of four different sizes of monodisperse aerosols and 4 pressure fall values.
Necessarily mean BTEX values starting from 0.01-0.sixty nine ppb were being derived from these new seven-working day UTRs and when compared with Those people from the archive. In comparison with concurrent info in Spokane, benzene and toluene final results had been statistically comparable (Chandra et al., 2020). Last but not least, history hazard concentrations from benzene have been calculated and proven to generally be lower. These can be referenced for long run wildfire seasons, or even in areas which are proximal to wildfires. The use of passive sampling with UTRs has benefits of significantly less samples to evaluate lengthy-phrase check here exposures and is also equally transportable and affordable. Software to wellbeing possibility eventualities is significant and demonstrative of your use in the sphere of environmental toxicology and human health and fitness.
