BATCH BIOREACTORS: WASTE WATER ENDOCRINE DISRUPTOR BIODEGRADATION BY WHITE ROT FUNGI
Křesinová, Zdena; Cajthaml, Tomáš
2013 - English
Endocrine disruptors (EDs) are members of a broad class of environmental organopollutants which are present in the environment. Due to the widespread presence in the surface water and wastewater, and their negative endocrine disrupting activity even at very low concentration, these EDs have received an increased attention in water quality management and health care. EDs encompass a variety of substances, including mammalian hormones (estrogens, androgens) and anthropogenic chemicals

TEMPERATURE INFLUENCE ON DESORPTION AND DETERMINATION OF BIOACCESSIBLE PAHS
Čvančarová, Monika; Pokorná, Lenka; Velebová, R.; Najmanová, P.; Cajthaml, Tomáš
2013 - English
Hydrophobic organic pollutants tend to adsorb onto soil particles which can cause a significant decrease in their bioaccessible fractions. Definition of the bioaccessibility is currently not unified; however it represents a part of total PAHs amount which is potentially available for biological processes. It is an important parameter which can be used for prediction of microbial degradation and environmental risk evaluation. This paper studies desorption behavior of PAHs at 20 and 60˚C. The desorption of PAHs from long-term contaminated soils was evaluated using resin Amberlite XAD- 2. A two-phase desorption model was used to calculate the desorption kinetic curves and F fractions which represent bioaccessible amount of PAHs. The results showed that the desorption of PAHs was significantly influenced by temperature. The greatest differences in the desorption behavior were observed at 5–6 ring PAHs. We compared the F fractions and the rate constants of individual PAHs which were determined at 20 and 60˚C. The results were also compared with sequential supercritical fluid extraction which has been already used for prediction of microbial degradation.
