  • Modelling dispersion of smoke from wildfires in a Mediterranean area

    We present a modelling system for the estimation of forest fire emissions ( prebolchem-fire ) and their inclusion in the atmospheric composition model BOLCHEM. Emission fluxes have been estimated following the methodology proposed by Seiler and Crutzen (1980) and using MODIS ‘burned area product’. Then they are modulated following the WRAP approach (WRAP, 2005). This approach is also used for ...

  • Numerical simulation of aerosols in an aircraft wake using a 3D LES solver and a detailed microphysical model

    The global impact of aviation on the atmosphere is generally determined using the total amount of gas and particulate matter emitted at the aircraft engine exit but generally ignore some of the physical transformations occurring at much smaller scales in the aircraft wake. In this work, we present an offline alternative method based on the use of a detailed plume aerosol model combined to fluid ...

  • The Important Job of Oil Mist Collectors

    The majority of business owners whose manufacturing process requires machinery that uses coolants, lubricants, or oils know how vital it is to keep the spray or mist released, during the operation from collecting on walls, ceilings or floors as much as possible. Emissions that are uncollected, can lead to slippery surfaces and an unhealthy working environment, which is why an  ...

  • Towards the simulation of size-resolved aerosol over Europe: model and observations

    Knowledge of the number density and size distribution of atmospheric aerosols in the submicron size range is essential for estimation of the aerosol radiative effects and the health impact of particles. Ultrafine particles (UFP), i.e. particles with diameters <100 nm, have received increased attention in recent years with improved possibilities of measuring them. UFP originate from nucleation, ...

  • 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 ...

  • Source apportionment technique: inorganic aerosol transformation processes in the Milan area

    The CAMx chemical and transport Eulerian model has been applied over a domain focused on the Milan area (Northern Italy) for the whole 2004, on the basis of CityDelta III project input data set. Model results have been analysed by mean of the Source Apportionment technique at the Milan receptor. A quantitative analysis of the main processes governing the Secondary Inorganic Aerosols (SIAs) ...

  • 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 ...

  • Carbon Tetrachloride and Prop 65, What You Need to Know

    In 1986, California voters approved an initiative to address increasing concerns about exposure to toxic chemicals. That initiative, the Safe Drinking Water and Toxic Enforcement Act of 1986, is better known by its original name of Proposition 65.  Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase, in their homes or ...

  • Influence of sea-land breezes on the tempospatial distribution of atmospheric aerosols over coastal region

    The influence of sea-land breezes (SLBs) on the spatial distribution and temporal variation of particulate matter (PM) in the atmosphere was investigated over coastal Taiwan. PM was simultaneously sampled at inland and offshore locations during three intensive sampling periods. The intensive PM sampling protocol was continuously conducted over a 48-hr period. During this time, PM2.5 and ...

  • A high-performance aerosol concentrator for biological agent detection

    Introduction Particle sampling from ambient air is a well-developed technology described in many texts (e.g., Vincent 1989; Willeke and Baron 1993; Hinds 1999). However, there are many cases in which the concentration of airborne particles is so low that it becomes necessary to sample for extended periods of time to collect enough mass for chemical or biological characterization of the ...

  • Detection of Airborne Viruses in a Pediatrics Department Measured Using Real-Time qPCR Coupled to an Air-Sampling Filter Method

    Children are vulnerable to viral infections. The study discussed in this article investigates the possibility of aerosol transmission of viruses in children under age 18 in the pediatrics department of a medical center in Taipei, Taiwan. After first using the filtration method to collect viral aerosols, the authors combined it with real-time quantitative polymerase chain reaction (qPCR) to detect ...

  • Determining saccharidic tracers in atmospheric aerosols

    Atmosperic aerosols have a strong impact on the climate. Within the organic aerosol fraction, anhydrosugars and sugar alcohols are valuable tracers for biomass burning and biogenic sources. They are best determined by ion chromatography coupled to pulsed amperometric detection. Sample preparation merely involves a simple waterextraction. Detection limits are in the ng/m3 ...

  • Variations in mass concentrations of airborne particulate matter over tropical urban environment

    Particulate matter (PM) is an important component of the air pollution that has adverse health effects, ecosystem damage and degraded visibility. We analysed the seasonal variations in PM loading from ground-based measurements of PM1.0 and PM2.5, Aerosol Optical Depth (AOD) Black Carbon (BC) aerosol over Hyderabad, India during January-June, 2006. The PM concentrations showed relatively higher ...

  • 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 ...

  • 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 ...
