  • Chemical loss of volatile organic compounds and its impact on the source analysis through a two-year continuous measurement

    Chemical loss of volatile organic compounds (VOCs) is more important than the observed VOCs, which is the real actor of the chemical process in the atmosphere. The chemical loss of VOCs might impact on the identification of VOCs sources in ambient. For this reason, VOCs with 56 species were continuously measured in the urban area of Shanghai from 2009 to 2010, and based on the measurement the ...

  • Train derailment prompts contaminated land investigation - Case study

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • Sliicer.com - Innovative On-line Software for Wet Weather Analysis

    This paper presents a sophisticated I/I analysis software tool that is available on-line to any City or engineering consultant. Probably the most common use of flow monitoring data is the analysis of flow during dry and wet weather. The analysis may determine if a sewer has capacity for development, to calibrate a hydraulic model or to analyze inflow and infiltration. Additionally cMOM envisions ...

  • Science and precaution in the risk analysis of chemicals

    This work shows the risk assessment procedures for chemicals and the factors that can determine the area of scientific uncertainty in the evaluation process, making the application of the precautionary principle necessary. The nature of the actions to be adopted on the basis of the precautionary approach, that is expressly included in the European Union Treaty, can be quite different. These ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Controlling Parameters in Water Analysis

    The COD (Chemical Oxygen Demand) is one of most important parameters in water analysis. In Germany as in nearly all European countries tax for indirect discharges is based on the COD. Using the oxygen consumption is reasonable in the case of tax because the delay time of waste water in a treatment plant depends mainly on its biological activity. The oxygen consumption again is a degree of ...
