  • A Procedure for Determining Volumetric Shrinkage of an Unsaturated Soil

    Measurement of unsaturated soil volumes can be used to monitor drying shrinkage and allows calculation of the volumetric air content/moisture content relationship. From this relationship, the onset of significant desaturation can be established as a bound to the validity of conventional soil testing under saturated conditions and of conventional analysis procedures for the particular ...

  • Design methodology for background air pollution monitoring site selection in an urban area

    We present an air monitoring site selection procedure to determine the minimum number and location of monitoring stations to identify the occurrence of background concentrations greater than a reference value in an urban area. The objective technique reported here is based on the analysis of concentrations estimated using an urban dispersion model for at least one year of hourly information. As ...

  • Selection of Particulate Monitors

    The installation and operation of continuous particulate emission monitors in industrial processes has become well developed and common practice in industrial stacks and ducts over the past 30 years reflecting regulatory monitoring requirements. It supports requirements originating from LAPPC (Local Air Pollution Prevention and Control), IPPC (Integrated Pollution Prevention and Control), WID ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Asbestos monitoring – what monitor should I be using?

    Asbestos is the name given to a group of minerals that occur naturally as masses of strong, flexible fibres that can be separated into thin threads and woven. These fibres are not affected by heat and do not conduct electricity. Asbestos is chemically, relatively stable. For these reasons, asbestos has been widely used in many industries.  These four types are classified as follows:  ...

  • Instrument air case study

    Application Moisture is measured in instrument air to ensure that the air is properly dried. Problem Instrument air is used through-out a facility to protect delicate electronics, instruments, and to operate key process actuators. Many instruments also use instrument air to operate various pneumatic operators they might possess. Too frequently, there is ...

  • General Air Sampling Guidelines (PDF)

    This Standard Operating Procedure (SOP) provides guidance in developing and implementing sampling plans to assess the impact of hazardous waste sites on ambient air. It presents the United States Environmental Protection Agency/Environmental Response Team's (U.S. EPA/ERT's) approach to air sampling and monitoring and identifies equipment requirements. It is not within the scope of this SOP to ...

  • A Breath of Fresh Air for Your

    As the full effect of the Federal Clean Air Act (CAA) Amendments continue to impact today’s industry, many companies will be required to install new or additional air pollution control equipment.  With over two decades of proven success, catalytic oxidation is a popular method for controlling volatile organic compound (VOC) emissions.During the past 25 years, industry has made progress in ...

  • Sino-Norwegian air pollution projects

    A co-operation was established in 1995 to start the development of air quality management systems in China. The areas selected for planning were: Yantai for a monitoring and planning system for air and water quality; and Guangzhou for an air pollution optimal abatement planning tool. The projects were based upon a modern environmental surveillance and information system, developed in ...

  • Baseline data in air quality impact studies

    The main objective of this paper is to explain not only the importance of the baseline data in air quality studies but also the general procedures and steps involved in the baseline data collection. Special considerations on the instruments and measurements for a perfect baseline data collection are also emphasized in this paper. As an example, an adequate baseline data collection procedure which ...
