  • New applications of beam–plasma systems for the materials production

    Beam–plasma systems (BPS) are known to be a great prospect for the surface modification of organic and inorganic materials. The present paper considers the plasma–assisted synthesis and deposition from the point of view of the hybrid materials production. Pilot setups in which the above processes occur in the electron–beam plasma (EBP) and combined plasma (CP) are described. The results of the ...

  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...

  • What does `Corona` mean to you?

    If you heard the word 'Corona', what would you think of first? Beer? A crown? A solar corona? Maybe something else entirely? At Peak Scientific 'Corona' brings two things instantly to mind; Thermo Scientific's Corona Veo Charged Aerosol Detector, and the ...

  • Method 301 Evaluation of Candidate conditional methods case study

    A new metal emissions measurement and validation system has recently been developed that has the potential to significantly improve our understanding of metal emissions from a wide range of source categories. This system consists of: A continuous emission monitoring system (Xact-CEMS) An instrumental analyzer procedure (Xact-IAP) A sampling and analysis measurement method ...

  • Annual simulation of secondary pollution over northern Italy

    A secondary pollution modelling system for simulating airborne dispersion and chemical reactions is applied over a regional scale domain located in the North-West of Italy, where urban and industrial areas are present. It was found an overestimation of NO2 in the urban areas, probably due to an underestimation of the vertical diffusivity; the analysis of O ...

  • Scrubers with a level head

    The available methods for removing pollutants from a gas stream are numerous, to say the least. A popular method, scrubbers allow users to separate gases and solids by allowing the gas to come into contact with a liquid stream. In the end, the pollutants are washed away in the effluent, and the gas exits the system to be used in later processes or to be released into the atmosphere. For many ...

  • OTM 17: Determination of Metal Concentrations Using Filters and Solid Sorbents in XRF Analyisis case study

    Eli Lilly and Company (Lilly) operates a waste incineration system located at the Tippecanoe Laboratories in Lafayette, Indiana. This incinerator system includes an Xact multi-metals continuous emissions monitoring system (Xact-CEMS, manufactured by Cooper Environmental Services, LLC) for demonstrating attainment with the Hazardous Waste Combustor MACT for semi-volatile metals, low-volatile ...

  • Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

    Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...

  • Environmentally sound - Case study

    On March 16, 2018, the U.S. Environmental Protection Agency (EPA) proposed to add hazardous waste aerosol cans to the category of “universal wastes” regulated under the federal Resource Conservation and Recovery Act (RCRA) regulations, codified at Title 40 of the C.F.R., Part 273. 83 Fed. Reg. 11654. According to EPA, this action would benefit the many manufacturing facilities and ...

  • Remote sensing of particulate pollution from space: Have we reached the promised land?

    This paper follows presentation and publication of the Hoff and Christopher 2009 Critical Review and represents an integration of discussants’ views of their paper. The discussants’ comments are organized beginning with a note on the history of satellite sensing, followed with a brief discussion of the strengths and weaknesses of satellite observations relative to air quality management needs. ...

  • Using Hazard Analysis and Critical Control Point Water Management Plans to Prevent Legionellosis

    ABSTRACT Legionellosis is an environmental-source disease caused by Legionella bacteria. Many such diseases are prevented using a scientifically-based risk management process called Hazard Analysis and Critical Control Point (HACCP; pronounced “Hassip”). Water Management Plans based on HACCP have been proven effective for preventing legionellosis. Perspective is given for how ...

  • New York Legionella regulations: are they missing the boat?

    Abstract A large outbreak of Legionnaires’ disease in the Bronx in 2015 prompted NYC to enact law and NYS to propose emergency regulations on the registration and maintenance of cooling towers. This paper describes the fundamental characteristics of point sourced vs. potable water sourced outbreaks and discusses the Bronx outbreak from those perspectives. Ultimately a case is made that ...

  • Scientists call manmade chemicals like refrigerant gases a cause of climate change

    A major cause of climate change is the harm that is done to the Earth by man-made chemicals. Whilst chemicals, such as those used to produce day by day items, operate equipment and generally make life easier, are necessary, they present a threat to the environment. Governments around the world have set new regulations to limit the use of substances that contribute to global warming and deplete ...
