Automatic weighing system vs. manual weighing precision comparison in PM-loaded filter measurements under different humidity conditions.

Currently, there is a lack of research directly comparing the precision of automatic weighing systems and manual weighing in the context of particulate matter (PM) filter equilibration and measurements under different humidity conditions. During experimental measurements, three different types of PM-loaded filters were weighed using manual and automatic balances. During manual weighing, every filter was weighed twice in three different relative humidity conditions.

Inhalation Exposure to Gaseous and Particulate Bound Mercury Present in the Ambient Air over the Polluted Area of Southern Poland.

This study concerns the concentrations of gaseous and particle-bound mercury present in ambient air of two Polish sites, differing in terms of emission structure, and the estimation of inhalation risks related to those Hg species. The measurements of total gaseous mercury (TGM) and PM-bound mercury (PBM) were performed at an urban station in Zabrze and a rural station in Złoty Potok, in 2014-2015. Both sites are located in Silesia, considered one of the European air pollution hot-spots.
