  • Persistent organic pollutants in the Arctic

    Persistent organic pollutants (POP) have been subject to research at NILU for a long time. These substances are toxic and are of anthropogenic origin, they accumulate in the environment, and they move through the environment so that after a discharge their traces including transformation products can be found in far-away places in air, water, soil and biological ...

  • Using UV Fluorescent Technology to monitor for organic pollutants

    For many years the water industry has relied on traditional sampling techniques to monitor water quality in a wide range of environments. Traditional tests such as BOD, PH, Dissolved Oxygen and Ammonia have formed the bedrock of monitoring parameters. There are however other ways to establish water quality and UV fluorescence offers an up to date solution for the investigation of ...

  • Modified biopolymer adsorbent for the removal of dissolved organic pollutants

    Chemically modified cellulose fibres were used as adsorbents for the removal of organic compounds and herbicides from water. The chemical modification of fibres by grafting hydrocarbon moieties enhances the adsorption capacity of cellulose substrate. The adsorption behaviour of the modified fibres towards various organic solutes and three herbicides was investigated. The viability of application ...

  • Metals and organic pollutants in snow surrounding an iron factory

    Abstract To estimate air pollution snow samples were collected in March 2001 at six sites in the vicinity of the Kostomuksha factory in Karelia. Seventy-two chemical elements and more than 200 individual organic compounds were identified by inductively coupled plasma mass spectrometry (ICP-MS) and gas chromatography mass spectrometry (GC-MS). It was found that the levels of Li, B, Al, Fe, Ni, Cu, ...

  • Screening of volatile organic compounds as a source for indoor pollution

    For a considerable period of time the presence of an increasing number of chemicals has been observed in almost all aspects of human life. This process also affects the living and working environment of man. Human development, including physical and mental health and well-being, depends on to a great degree on the surrounding environment. Considering that an average person spends a significant ...

  • Ozone treatment of organic micro-pollutants in sewage sludge

    Organic micro-pollutants accumulate to a certain extent in sewage sludge and are therefore ecologically relevant if the sludge is to be reused in both agriculture and landscaping applications. This paper describes the degradation of endocrine-disrupting compounds and other micro-contaminants by means of ozone and ultrasonic treatment. One of the findings is that, as expected, aromatic compounds ...

  • Cattle egrets as a biosentinels of persistent organic pollutants exposure

    We investigated selected chlorinated pollutants (β-HCH, γ-HCH, DDDs, DDEs, o,p′-DDT, p,p′-DDT, heptachlor, aldrin, dieldrin, and endrin) in the Lahore and the Sialkot districts of Pakistan, using eggs of cattle egret (Bubulcus ibis) collected during May and June 2007. The pollutant with highest level and frequency was ΣDDT, followed by β-HCH, γ-HCH, ...

  • Land use patterns and organic pollution in the rivers

    The riverine system is an important resource of water supply to the communities but rivers are being contaminated due to organic pollutants, which is a serious problem. Organic contamination has been discussed with regard to the different rivers of the world. Various organic pollutants, detected in water and the sediment of the rivers, have been reported. The effects of different land use ...

  • Priority organic pollutants in the urban water cycle (Toulouse, France)

    Application of the European Water Framework Directive requires Member States to have better understanding of the quality of surface waters in order to improve knowledge of priority pollutants. Xenobiotics in urban receiving waters are an emerging concern. This study proposes a screening campaign of nine molecular species of xenobiotics in a separated sewer system. Five sites were investigated ...

  • Preparation and selective adsorption of organic pollutants by an inorganic molecular imprinted polymer

    A novel inorganic molecular imprinted polymer (MIP) was synthesized by adding Al3+ to the Fe/SiO2 gel with Acid Orange II (AO II) as the template. The MIP was characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy and nitrogen adsorption-desorption measurement. Compared with the non-imprinted polymer (NIP), the MIP enhanced the ...

  • Organic and metallic pollutants in water treatment and natural wetlands: a review

    A literature review shows that more than 500 compounds occur in wetlands, and also that wetlands are suitable for removing these compounds. There are, however, obvious pitfalls for treatment wetlands, the most important being the maintenance of the hydraulic capacity and the detention time. Treatment wetlands should have an adapted design to target specific compounds. Aquatic plants and soils are ...

  • Synthesis of ZnO-CuO/MCM-48 photocatalyst for the degradation of organic pollutions

    The photocatalytic properties of ZnO-CuO catalysts supported on siliceous MCM-48 (Mobil Composition of Matter No. 48) for the degradation of organic pollutions such as methylene blue and salicylic acid under UV light irradiation were investigated. These catalysts were prepared by impregnation of MCM-48 with a mixed aqueous solution of copper acetate and zinc acetate. X-ray diffraction, ...
