A highly oil-polluted soil from Krasnoe in North-West Russia was used to investigate the degradation of organic pollutants during electrodialytic remediation. Removal efficiencies were up to 70 % for total hydrocarbons (THC) and up to 65 % for polyaromatic hydrocarbons (PAH). Relatively more of the lighter PAH compounds and THC fractions were degraded. A principal component analysis (PCA) revea...

Sharon Doty received a BS degree in genetics from the University of California, Davis (1989), and a PhD in Microbiology from the University of Washington (1995). She did postdoctoral research in plant biochemistry (UW). Her current position is assistant professor in the College of Forest Resources, UW. Her research program covers three main areas: phytoremediation, the use of plants for removin...

Metal cations represent a considerable part among surface water and land pollutants. Industrial and agronomic effluents, containing in the most cases mercury, cadmium, lead and other cations, until now have been treated by mechanical, physicochemical and biological methods. Biological treatments are the most effective and economically suitable method. Anyway, even biological treatment could not...

Type 2 diabetes mellitus (T2DM) is a major and fast growing public health problem. Although obesity is considered to be the main driver of the pandemic of T2DM, a possible contribution of some environmental contaminants, of which persistent organic pollutants (POPs) form a particular class, has been suggested. POPs are organic compounds that are resistant to environmental degradation through ch...

Semiconductor heterogeneous photocatalysis, the subject of this review, is a versatile, low-cost and environmentally benign treatment technology for a host of pollutants. These may be of biological, organic and inorganic in origin within water and air. The efficient and successful application of photocatalysis demands that the pollutant, the catalyst and source of illumination are in close prox...

Biological processes, such as activated sludge and granular sludge are widely used to remove organic pollutants as well as inorganic pollutants, such as metallic elements1–3, which are known to be potentially toxic, and impact the performance of biological waste treatment processes4. Granular sludge is a dense aggregate of microorganisms, minerals, and microbial produced compounds such as extra...

The octanol–air partition coefficient KOA is a key physicochemical parameter for describing the partition of organic pollutants between air and environmental organic phases. Experimental determination of KOA is costly and time consuming, and sometimes restricted by lack of sufficiently pure chemicals. There is a need to develop a simple but accurate method to estimate KOA. In the present study,...

Composite heteronanostructures hold promise for high photocatalytic efficiency for water splitting and the degradation of organic pollutants. However, their photocatalytic activity under broadband excitation has been challenging, until now.

The introduction of oxygen in electrochemical oxidation at relatively high temperature and pressure as a promoter resulting in synergetic effects, greatly improves the mineralization of high-concentrated organic pollutants.
