AbstractThe textile industry is a large water consumer. Stringent regulations of wastewater characteristics require the use of membrane processes for the removal of persistent organic pollutants (POPs) from textile wastewater prior to discharge or recycling of these effluents.This paper presents an overview of research related to the removal of persistent organic pollutants from textile industry by membrane processes, discussing also the correlations with actual pre-treatment and removal rates. ...

AbstractLead is unique among the toxic air contaminants that the World Health Organization (WHO) has identified it in several ways. Lead concentration is increasing rapidly in the environment due to increased use in anthropic activity. Lead is released into the atmosphere from metallurgy and siderurgy industry, during coal burning, oil or wastes, from power plants which use solid fuel, from traffic and the building sites. Regardless the exposure mode, the presence of lead in urban air, even in r...

Abstract Worldwide, tourism is the fastest growing major industry, but not all consequences are positive. This has lead to a growing attention for â€?sustainable tourism’. Compared to international guidelines, the current governance for sustainable tourism in the Netherlands proves to be very weak. Is this just because of stakeholders’ interests and their motivation to protect and conserve, on the one hand, or just encourage growth, on the other? We find some support for this, but also fi...

Abstract Tartrazine, (CI 19140) is an azo dye widely used in pharmaceuticals, cosmetics and foodstuff, as well as for coloring the textiles, hence it can be easily found in municipal wastewaters or wastewaters originating from textile, food, drugs and cosmetic industry. In this work, the capacity of a Romanian soil to retain Tartrazine from aqueous solution by sorption onto soil particles of different size has been investigated. The sorption kinetics was studied by applying five kinetic model...

Abstract Chlorophenols are contaminants in soils, sediments, surface waters and groundwater, largely because of their worldwide utilization in the last 50 years as wood preservatives and general biocides in industry and agriculture. The toxicity of chlorophenols and their persistence in the environment require advanced treatment techniques for their removal. Surfactant-modified natural zeolites (SMZs) represent an important class of sorbents for water treatment. This work presents a comparat...
