  • Using EDXRF to quantify the amount of Metals in Asphalt Binders

    This article reviews these sources and proposes a scheme for measuring and quantifying the amounts of metals in their source materials used to bind asphalt used in making roads. The use of bench top EDXRF to characterize binders before blending them into asphalt cements is possible because the metal values are in the 10s – 1000s of ppms and are readily monitored. ...

  • X-Ray Fluorescence-Based Multi-Metal Continuous Emission Monitor

    ABSTRACT: Army demilitarization incinerators will need to comply with the Hazardous Waste Combustor National Emission Standard for Hazardous Air Pollutants that will regulate metals and metal compounds listed under the Clean Air Act Amendments. A large problem for these incinerator operations is limited knowledge of the type and quantity of emitted metals, so that compliance may be determined ...

  • Field demonstration of a near-real-time multi-metals ambient fence line monitor case study

    National emissions standards for hazardous air pollutants (HAPs) are required under Section 112 of the Clean Air Act to limit the release of specified HAPs. Permitting, monitoring and enforcement of these emission limits are an integral part of managing air quality to protect human health and the environment. However, this is difficult and highly uncertain in the case of fugitive emissions ...

  • Monitoring Metal Contamination in Water

    Metal contamination in drinking and source water has proven to have economic and health impacts on the human race. Regulatory agencies understand the importance of remediating metal contamination in our water supply to ensure safe consumption of drinking water. In order to properly remediate our water supplies, one must first determine cause of contamination and the source of the problem. ...

  • Guide for developing a multi-metals, Fence-line monitoring plan for fugitive emissions using x-ray based Monitorsa case study

    Airborne metals and metal compounds are of particular concern to human health. Not only are they included in the United States (U.S.) Environmental Protection Agency’s (EPA) list of 187 hazardous air pollutants (HAPs), they represent 8 of the 33 urban pollutants identified by the EPA as posing the greatest potential health threat in urban areas. This is particularly significant since 80% of ...

  • Performance specification YY: Specifications and test procedures for Xray fluorescence based multi-metals continuous emission monitoring systems at stationary sources case study

    Performance Specification YY details the performance requirements for a multi-metals continuous emissions monitor that utilizes x-ray fluorescence (XRF) as an analytical technique. Each XRF based multi-metals CEMS must meet the criteria for accuracy, stability, and instrumental response laid out in this document. In addition, every XRF multimetals CEMS must meet the installation requirements in ...

  • Procedure Z: Quality assurance requirements for X-ray-fluorescence based multi-metals continuous emission monitoring systems at stationary sources case study

    Procedure Z outlines the continuing quality control and quality assurance requirements for an x-ray fluorescence based multi-metal CEMS. Procedure Z requires daily checks of the upscale, zero and volume measurement drift. It also specifies quarterly checks of the x-ray fluorescence calibration and of the volume measurement calibration. Finally procedure Z requires that the entire XRF multi metal ...

  • River Monitoring

    The monitoring of River water has impications not only on the environmental impacts of heavy metals but also upon the quality of drinking water. THis case study covers an analyser installed in a remote location using low voltage power supplies to suppliment the local mains power supply which cannot be relied ...

  • Multi-Stage Air Quality Monitoring in the Workplace

    CAS DataLoggers recently supplied the environmental datalogging solution for a factory with a small series of office rooms experiencing serious air quality issues. Employees reported headaches during the work day, indicating a possible lack of adequate ventilation. These workspaces were located next to the busy factory floor which caused an incidental ...

  • Monitoring heavy metals for compliance with RoHS and WEEE directives

    The rapid expansion in the quantity of used electronic and electrical appliances has created a need to safely dispose of the used equipment. The European Community has introduced regulations to enforce limits on the amount of toxic metals and organic chemicals used in the production of material. Compliance with the regulations will help prevent hazards for future generations when the equipment is ...


  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

  • A real-life test bed for multi-agent monitoring of road network performance

    This paper describes an approach to road network monitoring. The approach has the following main components: a multi-agent hierarchical monitoring system in which the agents are network elements such as crossings, road segments and routes, software engineering techniques to handle legacy sensors and to homogenise their heterogeneous data streams, distributed Kalman filtering to reduce sensor ...

  • Application of nanocrystalline metal oxide gas sensors for air quality monitoring

    Increasing concern regarding health effects caused by air pollution, together with the limited spatial resolution achievable with conventional monitoring stations, have driven efforts to develop inexpensive metal oxide gas sensors for air quality measurements. The sensing mechanism is dependent on physicochemical reactions between adsorbed gas molecules and oxygen species on the oxide surface, ...
