  • New Advances in Wet Scrubbing Improvements in Efficiencies

    Of all the air pollution abatement technologies, wet scrubbing systems remain the most versatile and cost efficient. New, patented advances in venturi scrubbing of air particulate, aerosols and gases easily achieves removal efficiencies greater than 99% for particulate and aerosols less than 3 Fm. Sub-micron particles present a special concern because they cause (at the very least) irritation of ...

  • Further analysis and PMF application to the chemical composition data of IPCAJ's Kashima SPM study

    The Industrial Pollution Control Association of Japan (IPCAJ) has conducted an air quality study. A brief summary has already appeared in previous papers. This set of data was not sufficiently analysed. This study attempts to examine the performance of the Positive Matrix Factorisation (PMF), a recently introduced technique in this field, on this multiple-site Kashima data set. The source ...

  • Urban indoor-outdoor aerosol measurements in Portugal and the global warming scenario

    Aerosols play a major role both in climate change and air quality. They affect climate by interfering with radiative transfer and the atmospheric temperature. Aerosol particulate matter has also been associated with various adverse health effects. Aerosol particles' number and size distributions were measured inside and outside the houses in the urban areas of Evora and Lisbon in Portugal. The ...

  • Large eddy simulation modelling of the dispersion of radioactive particulate matter

    Field experiments with a Radioactive Dispersion Device (RDD) were performed by the National Radiation Protection Institute (NRPI) of the Czech Republic. We present the results of computer simulations of these experiments using a new microscale model, Charles University Large Eddy Microscale Model (CLMM). The model was first validated using wind tunnel data for the dispersion of continuous passive ...

  • Polyurethane Foam as an Effective Adsorbent for Pesticides in Air (GC Analysis)

    Polyurethane foam (PUF) is a lightweight, easy-to-use material for sampling pesticides in air. Low back pressure allows sampling times and representative samples. A PUF filter cartridge designed to attach to the front of an ORBO-1000 PUF sampling cartridge traps aerosols and particulate matter, is easily and conveniently assembled, and can be removed from the ORBO-1000 cartridge and capped ...

  • The Effectiveness of HEPA Filters on DNA-Poster

    Abstract Objectives: Most laboratory techniques utilize biosafety cabinets (BSCs) in order to provide contamination control of the experiments. BSCs depend on airflow and HEPA filters to remove aerosols and particulates from the environment. Aerosols may be created constantly by common lab practices, such as centrifugation, pipetting, and opening tubes. The main principals of HEPA filtration ...

    9.2 Non-point source emissions   The DISPER model include algorithms to model line and area  sources, in addition to point sources. These non-point source options of the model are used to simulate the effects of emissions from a wide variety (conveyor belts, rail lines, area sources,…). The area source model is used to simulate the effects of fugitive emissions from sources such ...

  • Pondering a future of severe aerosol pollutions in Nigeria and the need for a monitoring network

    Nigeria is usually under the influence of significant natural aerosol loading. The country is the most populous in Africa with an estimated number of over 130,000,000 people and records one of the highest population growth rates in the world. It is the sixth largest oil-producing country in the world and a regional power in West Africa with great potentials for rapid industrialisation and ...

  • Airborne chemical elements: correlation between atmospheric levels and lichen content

    Concentrations of As, Cd, Co, Na, Sb, Se and Zn have been measured in atmospheric particulate matter and Parmelia sulcata Taylor transplants at a suburban and industrial area. Levels in particulate matter were found to be much lower than European target values, Californian Acute Inhalation Reference Exposure Levels and Ontario's Ambient Air Quality Criteria. Correlations between elemental content ...

  • Relation of earth probe TOMS/AI data and ground level measured atmospheric aerosols over Marmara region

    The main aim of this study is to statistically investigate the correlation between TOMS/Aerosol Index (AI) remote sensing particulate data and Ground Level (GL) aerosol concentrations. GL fine and coarse particles are collected from watershed area of Buyukcekmece at Marmara region in Istanbul, Turkey (41°0.04′ N; 28°0.59′ E). Randomly collected, 24 hr GL samples are statistically compared with ...

  • Particulate matter, halogen and aerosols - Case Study

    Example: Production of anodes for aluminium smelters as well as electronic industry (TFT-LCD) Similar tasks: Carbon and graphite industry, smelting of aluminium, coating of metals An anode producer has several ring furnaces to stabilise the anodes by carbonization for later processing in a melting bath. The hot exhaust gases pass through double walls in between the anodes where the gases ...

  • Aerial Radiation Detection

    In this time of multiple threats to our security: dirty bomb; cyber; shooters in public places; homemade bombs; misinformation; etc. we feel extremely vulnerable; perhaps more vulnerable than ever before. With the advent of Drone technology now available to private citizens, technology previously only held by the military, the opportunity has come to marry Drone Technology with aerial sensors. ...

  • Monitoring of Terpene Emissions from Pine Trees by Auto-TDGCs

    It has been established that organic aerosols (OA) makes up a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass. Primary OA is directly emitted in the trophosphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic ...

  • Aerosol characteristics at a continental urban station in southern India

    Spectral Aerosol Optical Depth (AOD), Black Carbon (BC) mass concentration and Suspended Particulate Matter (SPM) measurements were made at an urban continental location, Bangalore (13°N, 77.6°E), in southern India. These results show that AODs reach a maximum during April (∼0.5) and minimum during December (∼0.2) at 500 nm. BC and SPM showed variations of 0.6-4.2 μg m³ and 120-195 μg m³, ...

  • Particulate matter from natural sources and related reporting under the EU Air Quality Directive in 2008 and 2009

    Much of the air pollution that damages human health and the environment today is the result of human activities. But natural sources also emitt air pollutants, contributing to the exposure of European citizens and ecosystems to bad air quality — and potentially undermining EU Member State efforts to meet the air quality standards set out in EU legislation. Recognising the challenge ...

  • Nanoparticles

    Nanoparticle Definition “Nanoparticle” is a catch-all term. There is no consensus on definitions or nomenclature for nanoparticles or nano aerosols. Other terms for this material include “Ultrafine Particle” (less than 100 nm in diameter). Current terminology for measuring worker exposure to particulates does not take particle size ranges into account. ...

  • Airborne particle measurements: 100 LPM vs. 1 CFM particle counters in a semiconductor cleanroom environment

    Abstract Many current standards define airborne particle monitoring in units of particles-per-cubic-meter (particles/m3). Often, these standards require sampling an entire cubic meter (1 m3) to provide an accurate measurement of airborne particulate levels. Using a conventional aerosol particle counter that samples 1-cubic-foot per minute (1 CFM) requires more than 35 minutes to sample 1 ...
