  • 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 ...

  • Estimation and Mapping of Wet and Dry Mercury Deposition Across Northeastern North America

    Whereas many ecosystem characteristics and processes influence mercury accumulation in higher trophic-level organisms, the mercury flux from the atmosphere to a lake and its watershed is a likely factor in potential risk to biota. Atmospheric deposition clearly affects mercury accumulation in soils and lake sediments. Thus, knowledge of spatial patterns in atmospheric deposition may provide ...

  • A new sustainability model for machining processes

    It is generally recognised that the sustainability concept integrates economic, environmental and social aspects. It would be interesting for manufacturers to be able to know which process, workpiece materials or machining condition is more sustainable than another. In this paper, a new model for the sustainability in the machining field is proposed with the goal to increase productivity, reduce ...

  • SMEDIS: scientific model evaluation of dense gas dispersion models

    SMEDIS is a project currently in progress to develop a protocol for the scientific evaluation of dense gas dispersion (DGD) models, with particular emphasis on the complex effects of obstacles, terrain and aerosols often found in real situations, and then to apply this protocol to DGD models currently in use in Europe. This paper describes the general features of a model evaluation project and ...

  • Monitoring Airborne Contaminants in Workplace Atmospheres, Using Sampling Devices and GC or HPLC

    Workers' exposure to hazardous substances must be held within acceptable limits. Therefore, airborne contaminant vapor and particles (including aerosols) in industrial atmospheres must be monitored. In the United States, the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) offer, for many such substances, specific ...

  • 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 ...

  • 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 ...

  • 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 ...
