The synthesis of existing Persistent Organic Pollutants pollution monitoring databases with epidemiological data is considered for identifying some impacts of Persistent Organic Pollutants on human health. This task requires new, rich, data, services and models discovery capabilities from a multitude of monitoring networks and web resources. The FP7 project TaToo (Tagging Tool based on a Semant...

The influence of low-molecular-weight organic acids (LMWOAs), such as malonic acid, ethylenediaminetetraacetic acid, and oxalic acid, on the Fenton degradation of organic pollutants was examined under visible irradiation (lambda > 450 nm). The Fenton degradation of malachite green in the dark was completely blocked in the presence of LMWOAs. It was found that either visible light irradiation or...

In recent years there has been a growing concern all over the globe, about marine pollution due to persistent organic pollutants. Sediments, which are an important component of marine environment can serve as sorbents or concentrators for various persistent organic pollutants, including Polychlorinated Biphenyls (PCBs). In this study, the depth profile of accumulated PCBs in Thane Creek sedimen...

Ground level ozone, airborne particulates (TSP), carbon monoxide, volatile organic compounds (VOCs), nitrogen oxides and sulfur oxides and lead are all regulated and monitored closely by the EPA and are termed "criteria air pollutants." They are considered to be some of the most damaging pollutants because they are so prevalent. Their impacts have been studied extensively, and much benefit cost...

Persistent organic pollutants, POPs (e.g., polychlorinated biphenyls) can seriously and deleteriously affect environmental quality and human health. These organic pollutants are exhibiting high affinities to solid phases and thus, quickly end up in sediments. To better understand the role of carbonaceous materials in the transport and distributions of POPs in terrestrial and near-shore environm...

We describe the use of catalytically self-propelled microjets (dubbed micromotors) for degrading organic pollutants in water via the Fenton oxidation process. The tubular micromotors are composed of rolled-up functional nanomembranes consisting of Fe/Pt bilayers. The micromotors contain double functionality within their architecture, i.e., the inner Pt for the self-propulsion and the outer Fe f...

Enzymatic degradation of organic pollutants is a new and promising remediation approach. Peroxidases are one of the most commonly used classes of enzymes to degrade organic pollutants. However, it is generally assumed that all peroxidases behave similarly and produce similar degradation products. In this study, we conducted detailed studies of the degradation of a model aromatic pollutant, Sulf...

Millions of tons of wastewater containing both inorganic and organic pollutants are generated every day, leading to significant social, environmental, and economic issues. Herein, we designed a graphene foam/TiO2 nanosheet hybrid, which is able to effectively remove both chromium (VI) cations and organic pollutants simultaneously. This graphene foam/TiO2 nanosheet hybrid was synthesized via a f...

The NiO/NiS composite catalyst synthesis is designed using a simple and facile method. Composite materials with different sulfur sources were characterized and applied for catalytic reduction of 4nitrophenol (4-NP) in aqueous solution. The catalysts' universality towards reduction/decolorization of other organic dyes such as methylene blue (MB), methyl orange (MO), and rhodamine B (RhB) was eva...
