  • 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 ...

  • Introducing a New ASTM Method for the Determination of Total Nitrogen, and TKN by Calculation, in Water Samples

    The USEPA Clean Water Act (CWA) requires national approval for all methods used for CWA compliance. There are approved methods for the determination of inorganic nitrogen (NO3-N, NO2-N, and NH3-N), and for organic nitrogen (TKN – NH3-N)2. There are no EPA approved methods for the determination of total nitrogen although it is a required parameter in many USEPA permits, including monitoring ...

  • Optimizing VOC Combustion - Case Study

    Volatile Organic Compounds (VOCs) are pre-cursors to Ozone pollution and subject to EPA regulations. Thermal and catalytic oxidizers are routinely used to destroy VOC emissions from a variety of industrial sources. ...

  • Why Are CHP Closing All Over The World?

    Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use ...

  • Ammonium, nitrate, and total nitrogen determination in fly ash

    Fly ash is a by-product of the combustion of pulverized coal and is composed of small particles. The composition of the fly ash may vary considerably, however, all fly ashes contain substantial amounts of silicon dioxide (SiO2), aluminum oxide (Al2O3) and calcium oxide (CaO). Nowadays, air pollution control standards require a separation of flue gas before being released to the atmosphere. Fly ...

  • 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 ...

  • 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 ...

  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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, ...

  • Immobilization of organic pollutants in cement pastes admixed with organophilic materials

    The results of 2-chloroaniline (2-CA) immobilization experiments in cement matrices, using an organophilic clay modified with phenolic resins as pre-sorbent, are shown. The 2-CA suspended in water was kept in contact with the organoclay for 24 h, and the slurry obtained was then admixed with ordinary Portland cement (OPC) without additional water, to obtain a firm solid waste. Six cement—clay ...

  • P2 for SMEs: How to advance pollution prevention in small and medium-sized organizations

    Businesses in the small- and medium-sized enterprise sector are a vital part of the Canadian economy. So-called 'SME' firms have less than 500 employees and less than $50-million in annual revenues. But SMEs are the fastest growing facet of the Canadian economy, and as such are especially important to the successful adoption of pollution prevention (referred to as 'P2' in government circles). SME ...
