  • Implementation of radiological emergency monitoring systems post-fukushima

    The Fukushima Daiichi nuclear power accident in 2011 strongly highlighted the need to further strengthen effective regulatory control and oversight around Nuclear Power Plants. It also showed the need for renewed national safety and security regulations, in compliance with global safety standards and guidelines. All over the world, national and international agencies upgraded their safety plans, ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • AQMesh shown to achieve highest correlation coefficients in new ACS paper

    A new paper published by the American Chemical Society (ACS Sensors) reviews the use of amperometric electrochemical gas sensors for monitoring inorganic gases that affect urban air quality. Written by John Saffell and Ronan Baron of Alphasense, the paper gives a full explanation of how the sensors work, how they have developed and a review of ...

  • Is it time to upgrade the PM2.5 federal reference method?

    The fine particulate matter (PM2.5) Federal Reference Method (FRM) has in many respects been a great success. When the method was implemented, there was some doubt that the state and local monitoring agencies that routinely provide air quality data would be able to manage a program, which often distinguishes one location from another by just a few μg/m3. As it turns out, data from the FRM ...

  • Nuclear tools for characterising radiological dispersion in complex terrain: evaluation of regulatory and emergency response models

    Routine operations of a nuclear research reactor and its facilities offer opportunities for collection of rare environmental tracer datasets which can be used for atmospheric dispersion model evaluation studies. The HIFAR reactor near Sydney, Australia, routinely emits the radioactive noble gas 41Ar, and other radionuclides such as 133Xe and 135Xe are also emitted from nearby radiopharmaceutical ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Intraurban variability of Ambient PM Arsenic and other air toxics metals case study

    The Missouri Department of Natural Resources (MoDNR) and Washington University participated in a project to collect and analyze air toxics metals data. It was funded through a Community Air Toxics Grant from the U.S. Environmental Protection Agency (USEPA). The study grew out of the southside St. Louis Community Air Project (CAP) which identified six hazardous air pollutants of concern including ...

  • Cruise ship discharge assessment report

    Cruise ships operate in every ocean worldwide, often in pristine coastal waters and sensitive marine ecosystems. Cruise ship operators provide amenities to their passengers that are similar to those of luxury resort hotels, including pools, hair salons, restaurants, and dry cleaners. As a result, cruise ships have the potential to generate wastes similar in volume and character to those generated ...

  • A Method of Assessing Air Toxics Concentrations in Urban Areas Using Mobile Platform Measurements

    ABSTRACTThe objective of this paper is to demonstrate an approach to characterize the spatial variability in ambient air concentrations using mobile platform measurements. This approach may be useful for air toxics assessments in Environmental Justice applications, epidemiological studies, and environmental health risk assessments. In this study, we developed and applied a method to characterize ...

  • Airparif uses Isatis to process 11 million+ mesh grids and generate daily air quality maps - Case Study

    Isatis has been part of Airparif data processing workflow for 10+ years. The software is used daily to gather data and map air pollution over Paris area. The facts Airparif is part of the French AASQA network (“Associations Agréées de Surveillance de la Qualité de l’Air”). The AASQA are a French non-profit association accredited ...

  • Monitoring network for Scottish ports - Case Studies

    Historically, ferry masters operating off the west coast of Scotland would have to sail to a port and on arrival visually assess the weather and tide conditions before deciding whether safe berthing alongside the pier or quayside would be possible. This wastes time and fuel, and can causes immense frustration among passengers, who may see ferries come close to a port, but thereafter depart ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...

  • Prescribed burn smoke impact in the Lake Tahoe Basin: model simulation and field verification

    Smoke dispersion modelling based on the Fire Emission Production Simulator and the Hybrid Single Particle Lagrangian Integrated Trajectory (FEPS-HYSPLIT) model was applied to prescribed burns in the Lake Tahoe Basin (LTB) during fall 2011. This, in conjunction with measurements at sources and real-time ambient PM 2.5 monitoring around LTB, served to evaluate the prescribed burning impacts on ...

  • New NO2 air standards prove technically challenging

    On February 9, 2010, the U. S. Environmental Protection Agency (EPA) established a new National Ambient Air Quality Standard (NAAQS) for nitrogen dioxide (NO2). The new NO2 NAAQS is a one-hour standard set at 100 parts per billion (ppb), which is approximately 188 micrograms per cubic meter (μg/m3). Effective on April 12, 2010, the new one-hour standard is intended to protect against peak ...
