  • Chemical Pollutants in Water Emerge

    Recent advances in contaminant identification methodologies, sampling instrumentation, and analytical chemistry have caused an explosion of knowledge about the presence of previously undetected organic micropollutants. While it doesn’t follow that the mere presence of chemical contaminants results in harm, public health experts, regulators, and others aren’t sitting idly ...

  • PFC Pollution in the office environment

    A new study suggests that exposure to chemical pollution could be a particular problem in the office environment. Researchers in the United States have found a link between Polyfluorinated Compounds (PFCs) in the air of a number of offices and their presence in the blood of the people working there. Polyfluorinated Compounds are water and stain-resistant and they have been used for many ...

  • Survey on Existing Sample Archives For The Assessment of Time Trends of Pollutants in The Environment of New EU Member States and Candidate Countries

    Foreword Potentially high levels of chemical pollution in the EU+10 compared to the EU 15 Member States generate concern on the environmental status of the former. Especially contaminations in the agro-environment of the new EU MS may result in an increase of the overall human exposure in the enlarged EU. First attempts to collect concrete data on polychlorinated dioxins (PCDDs), -furans ...


  • Pollution monitoring in Cement Industry

    The rising use of waste based fuels in the cement industry, both for economic and Environmental objectives, combined with the strengthening of air emission regulations around the world is pushing many operators to face a wider list of pollutants to monitor this, with associated costs. The design of appropriate solutions meeting local regulation is the key to maximize the cost benefit of the fuel ...

  • Indicators of Pollution Management

    'The definition and selection of environmental performance indicators is still at an early stage but the use of indicators is increasing, both for the tracking of trends in pollution and other environmental issues at a large scale (national or regional) and also for the monitoring of Bank projects. This note provides a framework to assist in the selection of appropriate indicators for pollution ...


  • Analysis of the heavy metal pollutants in sediment samples collected from Thane Creek of Maharashtra, India

    The wetland of Thane Creek, located at Thane, Mumbai, India, has attracted much attention of environmental biologists over the last few decades, as this creek has been subjected to a lot of pollution from the Asia's biggest Thane–Belapur industrial complex located at the south of Mumbai harbour along the west coast of India. This paper advocates ecological studies with special reference to the ...

  • Chemical pollutants in water emerge

    Recent advances in contaminant identification methodologies, sampling instrumentation, and analytical chemistry have caused an explosion of knowledge about the presence of previously undetected organic micropollutants. While it doesn"t follow that the mere presence of chemical contaminants results in harm, public health experts, regulators, and others aren"t sitting idly by. Given the necessity ...

  • Measurement of TOC in High-Salt Sample

    The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

  • Groundwater: Low-flow Purging and Sampling

    Significant timesavings, improved sample process integrity, quality assurance and minimal quantities of potentially contaminated purge water to manage - are attractive as the focus on groundwater quality sharpens and economics demand best cost-benefit based methods Water has become a vitally important resource.  Maintaining its quality and quantity and avoiding pollution are set to be ...

  • Sucralose - a new persistent pollutant in the environment?

    Sucralose has been detected in Mjøsa and in the Oslofjord of Norway. Sucralose has been used as an artificial sweetener for nearly 30 years, and today the compound is approved as sweetener in more than 80 countries. NILU has developed a new method for screening of sucralose in environmental samples and due to the water-accumulation potential, the fate and impact of sucralose in aquatic ...

  • Water pollution · Canarina DESCAR software

    Natural waters contain micro-organism as well as solutes. There is a distinction between ‘pure’ water, meaning water that is fit to drink and pure water that is a single substance. A water pollutant is a substance that prevents the use of water for a specified purpose. The signs of polluted water are obvious. Poor drinking water tastes and smell bad. ...

  • The Economic Toll of Pollution’s Effects on Health

    Measuring and valuing the health impacts of pollution are very complex and available methods of economic analysis are often rudimentary. In recent years, considerable progress has been made, especially in respect to air pollution. This note summarizes the latest findings and outlines some basic approaches that can be applied in the economic analysis of Bank projects and sector studies. However, a ...


  • Removal of heavy metals from samples of residual sludge

    Nitric acid leaching processes were evaluated for removal of heavy metals from samples of residual sludge from an industrial and municipal wastewater plant. The study showed that an acid:water ratio of 1:1 and a nitric acid concentration of 2 mol 1−1 gave efficient removal of 86.7%, 100% and 100% of copper, nickel and arsenic.Keywords: heavy metals, nitric acid leaching, ...

  • Is the Rotameter Ready for Retirement in Air Sampling/Monitoring Applications?

    The variable area rotameter has been the primary tool utilized for determination of flowrates passing through the air circuitry pathway of air sampling or air monitoring systems for many years. In air sampling applications a pollutant is captured on a collection medium (filter paper, charcoal cartridge, etc.) and taken to a laboratory for determination of the quantity of pollutant on the ...

  • Effect of sampling duration on the performance evaluation of a stormwater wetland

    In this study, the effect of sampling duration on the performance estimate for a stormwater wetland over both rainy and dry days was evaluated for the appropriate design of sampling duration. As the cumulative percentage volume (Vp), the ratio of cumulative stormwater volume concerning time to the total stormwater volume, varied between 60 and 100%, generally, the inflow total suspended ...

  • Sustainable sampling of native bromeliads for environmental monitoring

    By analysing the leaves of bromeliads, the availability of chemical elements in the atmosphere can be assessed. However, sampling steps affect the reliability of using such plants for environmental quality studies. This paper describes a novel and sustainable sampling methodology for conservation units, in which small discs (6 mm diameter) of bromeliad leaves could be taken without removing ...
