The concentrations, distribution and modes of occurrence of trace elements in coal is mainly influenced by geological factors like depositional environment and other physical and biogeochemical factors during its formation (Hower et al. 2007; Li et al. 2016).
The calculation of air velocity, temperature, mean age of air, CO2 and TVOCs concentrations distribution in the room with various height positions (Z = 0.8 m to 2.6 m) of the return vents was carried out.
The thermal environment indices (temperature gradient and draught rating), indoor air quality indices (mean age of air, air change efficiency, CO2 and TVOCs concentrations distribution) and energy saving are analyzed and compared against each other.
In this study, we investigate the key differences in dissolved organic carbon (DOC) characteristics and its relationship with differences in elemental concentrations, distribution of biomarkers, and utilization of DOC by in situ microbial communities in BSA and GSA.
Many of the analyses were conducted using seasonally stratified data, given the differences in pollutant concentrations, distribution, and meteorology occurring in warm compared with cool seasons.
The cytotoxic potential can be influenced by the particle sizes and concentrations, distribution to different regions of the cell, or liberation of Cd2+ from the nanoparticle lattice [ 28, 29].
