  • 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 ...


  • Heavy Metal Monitoring Around the Nesting Environment of Green Sea Turtles in Turkey

    Abstract  The concentrations of Cd, Pb, Fe, Cr, Ni, Se, Sb, As and Cu were investigated in the nesting environment of green turtles in Mediterranean Sea near Kazanlı, Mersin-Turkey. Tissues of plants growing on the beach and the adjacent environment, beach sand, sea ground sediment, sea grass as well as the egg shells from the nests were analyzed and the results showed no significant ...


  • 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 ...

  • Using biofilms for monitoring metal contamination in lotic ecosystems: The protective effects of hardness and pH on metal bioaccumulation

    Biofilms can make good bioindicators and biomarkers, offering a convenient tool to monitor metal contamination in streams that results from mine tailing sites. Biofilm metal content (Cu, Zn, Cd, Pb) as well as diatom diversity and the presence of teratologies (diatom abnormalities) were determined for biofilms from rivers with a variety of physico‐chemical properties across a metal ...

  • 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, ...

  • Metal Coating Emission Control

    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking ...

  • 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 ...

  • On the design of advanced metal oxide nanomaterials

    A novel growth concept and a low-temperature aqueous chemical growth (ACG) thin film processing technique are presented that aim to contribute to the rational fabrication of smart and functional metal oxide particulate thin films and coatings. Such purpose-built materials are modelled, designed, and engineered to match the physical, chemical, and structural requirements of their applications. The ...

  • 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, ...

  • Regional-scale monitoring of coastal contamination. Nutrients and heavy metals in estuarine sediments and organisms on the coast of Galicia (northwest Spain)

    We determined background levels of heavy metals in sediments and biota of estuarine environments and nutrient reference levels in sediments of the Galician coast. This region is characterised by having ria-type estuaries. The determination of these levels, which were affected by the geological heterogeneity of the area, was the basis that let us evaluate the contamination status of this coast. ...

  • Monitoring and assessing heavy metals in topsoils as potential diffuse pollutants in the Pyeongchang River Basin, Korea

    Topsoils, mainly from crop fields, orchards, forests, and barns around the Pyeongchang River, were collected to investigate their heavy metal concentrations. Pollution load index, ecological risk index, and enrichment factor were applied to assess levels of heavy metal contamination for topsoils. The concentrations of cadmium (Cd) (1.7 mg/kg) and chromium (Cr) (4.1 mg/kg) exceeded the troublesome ...

  • 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 ...
