The efficiency and economic aspects of phytoremediation technology using Phalaris arundinacea L. and Brassica napus L. combined with compost and nano SiO fertilization for the removal of PAH's from soil.

The paper presents an evaluation of efficiency and economic potential of the phytoremediation technology, based on the use of energy crops (P. arundinacea L. and B.

Influence of Integrated Membrane Treatment on the Phytotoxicity of Wastewater from the Coke Industry.

In this paper, coke wastewater that had passed through biological and integrated membrane processes (filtration on sand bed-reverse osmosis) was chosen to assess the phytotoxicity of selected industrial wastewater with regard to the test plant-. An innovative research technique in vitro test was conducted in a large scale phytothrone chamber on two matrices: cotton and Murashige and Skoog Basal Medium (MSBM). The toxicity of wastewater was evaluated for samples: (1) treated in the treatment plant by biological processes, (2) filtrated through a sand bed and filtrated (3) reverse osmosis (RO) membrane.

The evaluation of polycyclic aromatic hydrocarbons (PAHs) biodegradation kinetics in soil amended with organic fertilizers and bulking agents.

The aim of this study was to investigate the polycyclic aromatic hydrocarbons (PAHs) biodegradation kinetics in soils fertilized with organic amendments (sewage sludge, compost), bulking agents (mineral sorbent, silicon dioxide in form of nano powder), and novel compositions of those materials. The scope of conducted works includes a cyclic CO production measurements and the determinations of PAHs content in soil samples, before and after 3-months of incubation. Obtained results show that the use of both type of organic fertilizers have a positive effect on the PAHs removal from soil.

Vermiremediation of polycyclic aromatic hydrocarbons and heavy metals in sewage sludge composting process.

The main objective of this work was to study the dynamics of the degradation of polycyclic aromatic hydrocarbons (PAHs) during sewage sludge vermicomposting. This eco-biotechnology employing earthworms as natural bioreactors for decomposing of organic matter may be used for vermiremediation of particular pollutants present in various organic matter sources. In this experiment, sewage sludge was mixed with bulking agents and precomposted.
