Historical pollution with hexachlorocyclohexane (HCH) isomers of soil and groundwater unfortunately is an unsolved problem, especially in some countries where Lindane is still produced, as also in Europe in the surrounding areas of former production sites or landfilling sites usually due to inadequate long-term storage, treatment or recovery of these wastes. HCH removal technologies are usually dedicated to soil remediation, leachate treatment, water and wastewater treatment. This paper presents the research effor...

Cyclophosphamide (CP) is a cytostatic drug prescribed at large scale, which proved to induce toxic effect on ecosystems and cannot be removed by conventional wastewater treatment processes. Therefore, there is a need to test advanced degradation processes for its removal from wastewater discharges. CP photocatalytic degradation via UV-VIS irradiation was studied using a Nitrogen -doped TiO2 catalyst. The catalyst was synthesized as thin film deposited on glass substrate under nitrogen atmosphere technique. The inf...
