Nowadays, environmental pollution is constantly increasing, and depollution the most important challenge of 21st century. This paper a review organic pollutants in wastewater that can be removed by photocatalysis process. Also are presented specialized studies demonstrate removal from experimental conditions necessary to obtain high treatment efficiencies. The classes hydrocarbons, halo compoun...

A coupling kinetics model is developed to simulate the release and transport of landfill leachate pollutants in a deformable municipal solid waste landfill by taking into account of landfill settlement, seepage of leachate water, hydrolyse of insoluble and degradable organic pollutants in solid phase, biodegradation of soluble and degradable organic pollutants in solid phase and aqueous one, gr...

Bioretention, also known as rain garden, allows stormwater to soak into the ground through a soil-based medium, leading to removal of particulate and dissolved pollutants and reduced peak flows. Although soil organic matter (SOM) is efficient at sorbing many pollutants, amending the bioretention medium with highly effective adsorbents has been proposed to optimize pollutant removal and extend b...

An Era of Hazard: Persistent Organic Pollutants By Marco A. Olsen, S.J.D. Candidate In May 2001, representatives from over 122 countries, NGOs representing citizens and the chemical industry, met in Stockholm to adopt and open for signature The Stockholm Convention on Persistent Organic Pollutants. The Convention is a legally binding treaty designed to protect human health and the environment f...

Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), dioxins and furans are persistent organic pollutants with well-known toxicity and carcinogenic activity. These organic pollutants have the tendency to bioaccumulate, present little or no biodegradation and subsequently, could cause a menace to the ecosystems and human health. This review discusses the occurrence, fate an...

With the objective of water analysis, a microsystem was developed, by using Resazurin molecule as an indirect bio sensor. The detection principle consists to monitor optically the oxygen consumption of E. Coli bacteria towards their metabolism in presence of organic pollutants. Thus, aiming on Glucose detection, a concentration-dependent inhibition effect on oxygen consumption rate was evidence...

objective: to determine the levels of polychlorinated biphenyls (pcbs) and polybrominateddiphenyl ethers (pbdes) as persistent organic pollutants (pops) in serum of primiparous women at the third trimester of pregnancy and identify the main determinants of pops levels such as socio-demographic, lifestyle, and diet in tehran. materials and methods: one- hundred eighty five serum samples from two...

conclusions results indicated that annular fluidized bed reactor’s adsorbers are useful techniques for vocs adsorption. comparison of two particle ranges indicates that in all concentrations and all flow rates of the experiments, smaller particle size adsorption are better. in superficial velocity above the minimum fluidization velocity, pressure drop of fluidized beds are less than the pressur...

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 model discovery capabilities from a multitude of monitoring networks and web resources. The FP7 project TaToo (Tagging Tool based on a Semantic...
