Expect Tighter Particulate Matter Standards

Particulate matter (PM) is a hot button issue poised to raise business costs and litigation. The U.S. Environmental Protection Agency (EPA) was recently due to issue final PM standard revisions. EPA last year proposed stronger National Ambient Air Quality Standards (NAAQSs) for fine PM (2.5 micrometers or less in diameter (PM2.5)) and the 24-hour PM2.5 standard. However, EPA sought to keep annual ...

Element patterns for particulate matter in stormwater effluent

Particulate matter in stormwater deteriorates the quality of receiving water and sediment. Characterization of stormwater particulate matter by means of its particle-associated element pattern provides an aid to determining its impact on receiving surface waters. During a 6 month measurement campaign, we determined particle-associated concentrations of major pollutants and rare earths for three ...

Sources of particulate matter: emission profile of biomass burning

Biomass burning is an important source of atmospheric Particulate Matter (PM) in Brazil: the burning of forests in the northwest and of sugar cane plantations in the southeast are important examples. The objective of this work is the measurement of the PM emission profile of burning of sugar cane and other characteristic vegetative burning in the region of Sao Carlos-SP/Brazil. Samples of PM10 ...

Trends of lead in suspended particulate matter in Zagreb air

Monitoring of lead in Total Suspended Particulate Matter (TSPM) started in Zagreb, Croatia in 1971 at three measuring sites. Monitoring of lead concentrations in PM10 started in 1999. This paper presents the trends of annual mean values for lead concentrations in TSPM and in PM10 particles. The obtained data showed a decreasing trend of lead in TSPM, especially during the last ten years when the ...

Suspended Particulate Matter Definition - SPM and RSPM

There is much confusion about how to define PM10 particulate, but if articles indicate the definitions they used then the information can be compared with information from other studies. A concern is that the dust measurement equipment for PM10 particulate matter might not be designed to meet the same defined standard as used in the articles which could lead to some discrepancies. ...

Particulate matter: Comparison between two bus fuels

AbstractParticulate matter is a dangerous polluting. Particulate health effects depend from two factors: mass concentration and chemical-physical particles composition, as chemical marker, size and morphology. Particulate health risk factor is due to particles penetration in respiratory system. The aim of this work is based on the physical characterization of particulate matter emission from two ...

In-Vehicle exposures to particulate matter and black carbon

ABSTRACTIn-vehicle exposures to particulate matter (PM) and black carbon (BC) can be a significant part of personal totalexposure. The purpose of this study was to identify determinants of the in-vehicle pollutant level. This study measured in-vehicle exposure to PM number concentrations using an aerosol spectrometer and BC concentration by an aethalometer. The measurement was repeated 3 ...

Spatial and temporal differences of Particulate Matter in Berlin

Particulate Matter (PM) is still a problem in urban areas. The concentration of PM in Berlin and its variability is the subject of this study based on data of six official PM10 monitoring stations and a measuring program carried out by the Institute of Geography covering PM2.5 and coarse PM measurements at 19 sites, distinguished between traffic related and urban background sites. The impact of ...

Frequency distribution of particulate matter (PM10) in urban environments

Hourly measurements of particulate matter with an aerodynamic diameter less than 10 µm (PM10) were recorded in Athens, Greece and Manchester, UK, for a period of one year. The lognormal, gamma and Weibull distributions were selected to fit the concentration frequency distribution of the measured PM10 data. Moreover, the statistics of Mean Bias Error (MBE), Root Mean Square Error (RMSE) and index ...

Particles Matter

We all can recall our mothers telling us as children to go outside and get some fresh air. Who would have known just how important this statement was and is today? Air pollution affects the entire planet. You can't escape it anywhere not even inside your home or office. According to the United States Environmental Protection Agency (EPA), indoor air can be up to ten times more ...

Dispersion modelling of traffic particulate matter in city–scale area

This paper introduces utilisation of the CFD technique for modelling of PM10 (particulate matter 10 µm) dispersion in urban areas, with focus on detailed description of processes in the ground surface boundary layer. The description of deposition and re–suspension processes is introduced and applied on the city–scale model of the city of Brno (pop. 400,000). The air threshold ...

Particulate matter dispersion modelling along urban traffic paths

In this paper authors compare two different approaches of 10 μm particles (PM10) dispersion modelling in urban areas. The study is focused on comparison of the Eulerian-Lagrangian approach accurately describing particle aerodynamics and the passive scalar approach representing simplified alternative for description of dispersion processes. CFD code StarCD has been used for this study as ...

A study of polycyclic aromatic hydrocarbons in airborne particulate matter in central Taiwan

Two sampling sites in central Taiwan, at Hungkuang University (HKU) and Tunghai University (THU), were chosen to contrast the content of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere from November 2000 to April 2001. PAHs that arise from incomplete combustion of organic materials, especially fossil fuels, are the major toxic pollutants in central Taiwan. This study aimed to analyse ...
