Review of recent advances in detection of organic markers in fine particulate matter and their use for source

ABSTRACTFine particulate matter is believed to be more toxic than coarse particles and to exacerbate health problems such asrespiratory and cardiopulmonary diseases. Specific organic compounds within atmospheric fine particulate material can be used to differentiate specific inputs from various emissions and thus is helpful in identifying the major urban air pollution sources that contribute ...

Fine Particulate Series (Part 3): PM2.5 prevention of significant deterioration (i.e., Attainment) – What you need to know

U.S. EPA’s final rules (and policies) governing the implementation of the New Source Review (NSR) program for fine particulate matter (i.e., particulate matter with an aerodynamic diameter less than 2.5 microns, or PM2.5) are now being implemented. In the March 2009 issue of 4 The Record, ALL4’s PM2.5 Team discussed the technical basics of PM2.5. Then, in the April 2009 issue, ...

The invisible fine dust

Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly dangerous. According to a current study conducted by the Max Planck Society, ...

Size and composition distributions of particulate matter emissions: Part 1 — Light-Duty Gasoline Vehicles (LDGVs)

Size-resolved particulate matter (PM) emitted from lightduty gasoline vehicles (LDGVs) was characterized usingfilter-based samplers, cascade impactors, and scanning mobility particle size measurements in the summer 2002. Thirty LDGVs, with different engine and emissions control technologies (model years 1965–2003; odometer readings 1264–207,104 mi), were tested on a chassis dynamometer using the ...

Particulate polycyclic aromatic hydrocarbons in urban air of Tehran

Epidemiological studies have shown correlations between the concentration of particles in the air and increase of daily rates of respiratory and cardiovascular diseases and mortality (Douglas et al.,1992; Jonathan et al.,1995; Auron et al.,1995). Elevated lung cancer rates among women in rural china have been attributed to emissions from their coal-fired stoves (Mumford et al.,1987;Alder and ...

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 ...

Scrubber Removes Grease and Particulates from Air Exhaust

Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

Short-term variations in ambient particulates and their sources in Taichung, Taiwan

Ambient particulate measurements were carried out using TE-PUF sampling and a Universal Air Sampler between 8 March and 25 April 2001 at Taichung. Samples were collected every 6 hours beginning at 0100 LST (Local Standard Time) each day at two sites, one at a university campus and the other at a roadside. Chemical species (Cl-, NO3-, ...

Office Printers Emit Ultra fine particle pollution

We’ve heard quite a bit about particulate matter PM10s and PM2.5s as components of air pollution that we are exposed to on a daily basis. Recent research papers are highlighting the dangers of ultra fine particles (UFPs), which have a diameter of less than 0.1 micrometres (or 100 nanometres). By contrast, the diameters of particulate pollution from PM10s and ...

Hydrocarbon evaporative emissions & control for automotives

Even the cleanest and most efficient vehicle on the market today still pollutes the air and otherwise damages the environment. Motor vehicles emit several noxious pollutants which vehicle emissions standards are designed to regulate. Vehicles generally emit Hydrocarbons (HC), Carbon monoxide (CO), Nitrogen oxides (NOx) and Fine airborne particulate matter (PM) as pollutants that require control. ...
