Method Development for Speciation Analysis of Volatile Mercury Forms in Ambient Air and flue Gases from Incineration Plants.
Švehla, Jaroslav ; Kratzer, J. ; Svoboda, M. ; Svoboda, Karel ; Šyc, Michal ; Ružovič, Tomáš
Potential of AAS for on-line speciation analysis of gaseous Hg0 (non-heated atomizer) and HgCl2 (heated atomizer) in flue gases is discussed.

Hydrodynamic Behavior of Bubbles in Slot Channels.
Ezeji, Kingsley ; Tihon, Jaroslav
We present the results of laboratory experiments investigating the dynamics of air bubbles rising in stagnant or co-flowing liquid (water) in inclined channels of rectangular crosssections. The experiments were conducted in a basic Plexiglas channel (1300 x 240 x 20 mm, in length (L), width (W), and height (H), respectively). Different channel geometries were obtained by insertion of suitably varied plates into the basic channel. Channel inclinations were ranging from alfa = 5̊ (almost horizontal) to 90̊ (vertical). Measurements and data analysis were carried out with the use of a high speed video camera system and image processing technique providing information on the bubble shape (bubble length LB and volume VB) and bubble rise velocity UB. The specific impact of channel geometry and inclination on the shape, stability, and velocity of rising bubbles was studied and discussed.\n

Elimination of Substances with Antibiotic or Estrogenic Activity from Dewatered Sewage Sludge.
Innemanová, P. ; Šereš, M. ; Pilnáček, V. ; Cajthaml, T. ; Křesinová, Z. ; Pohořelý, Michael ; Moško, Jaroslav
In our study, we focused on substances with inhibitory (antibiotic) and estrogenic (endocrine disruptors) activity to assess the unpredictable risk to the soil environment associated with the usage of sewage sludge as a fertilizer in agriculture.
