Atmospheric lead concentrations near roadways in a suburban part of Istanbul
In this study, daily aerosol samples of fine (PM2.5) and coarse (PM2.5−10) particles were collected at Buyukcekmece (41°2′35″N, 28°35′25″E), a sub-urban part of Istanbul, Turkey. Sampling area is under the impact of two main transport arteries, namely the Trans European Motorway (TEM) and E5 motorways. Atmospheric lead levels measured in this study were compared with those reported previously ...

Analysis of point source emissions in the Texas-Mexico border region
Pollutant emissions in the Texas-Mexico border were investigated using an emission database that covers 25 Texas counties and the states of Coahuila, Chihuahua, Nuevo Leon and Tamaulipas in Mexico. Major emissions are from energy generation, mainly from two coal-fired facilities in Coahuila, which also generate most of carbon dioxide. Texas exhibits a larger concentration of sources; around ...

Air–quality impact of PM10 emission in urban centres
This paper calculates a detailed inventory of PM10 emissions in the urban area of Mendoza, Argentina, and evaluates the impact of such emissions by using the CALPUFF dispersion program. It includes direct and indirect emissions from mobile sources; emissions from industrial sources and fugitive emissions from unpaved road and dust production from bare land. The main results show the relevance of ...

Use of abatement cost curves in developing environmental bubble policy for managing SPM in Jamshedpur region
This paper evaluates environmental bubble policy using abatement cost curves drawn for different abatement measures in Jamshedpur region. Surveys were conducted to estimate industrial emissions of suspended particulate matter (SPM) from different emitting sources in the region, and the characteristics of the existing and alternative abatement devices for each emitting source. The abatement cost ...

National Air Pollutant Emission Trends, 1900-1998
Executive Summary What information is presented in this report? This report presents the United States (U.S.) Environmental Protection Agency’s (EPA) latest estimates of national emissions for criteria air pollutants: carbon monoxide (CO), nitrogen oxides (NOX ), volatile organic compounds (VOC), sulfur dioxide (SO2 ), particulate matter (PM) less than 10 microns in aerodynamic diameter (PM10 ...

Effects of meteorological parameters on RSPM concentration in urban Delhi
The adverse effect of Respirable Suspended Particulate Matter (RSPM) has become a well-recognised problem in environmental science. Dispersion and dilution of air pollutants are strongly influenced by meteorological parameters, namely wind, turbulence, and atmospheric stability. The analysis of Delhi's air quality data shows that winter is the most critical season with respect to the ...

Air quality and ancillary benefits of climate change policies
Untitled Document This report analyses projected changes in European air quality up to 2030. It explores the possible benefits of climate policies on air quality and the costs of air pollution abatement. The results show that stringent EU climate change policies (aimed at limiting temperature rise to 2 degrees above pre-industrial levels) could: 1) improve Europe's air quality; 2) ...

New webinar now available on demand - Measuring opacity and particulate emissions from combustion processes
View our webinar where we introduce the concepts behind opacity and particulate measurement, describe the key technologies and provide detailed insight into the requirements for a successful installation. An opacity monitor provides a simple and robust means for emissions monitoring in combustion processes, but under some conditions a particulate matter (PM) monitor may be necessary. Overview ...

Traffic emission effects on ambient air pollution by PM2.5–related PAH in Upper Silesia, Poland
The ambient concentration of particle–bound polycyclic aromatic hydrocarbons (PAHs) was investigated in two industrial towns in Upper Silesia, Poland. The 24 h samples of PM2.5 (particles with aerodynamic diameter ≤ 2.5 µm) were collected simultaneously at busy roads (or crossroads) and at an urban background site. Additionally, the samples were collected during the heaviest traffic density (rush ...

Lisbon air quality: evaluating traffic hot-spots
This paper presents an air quality study in an urban traffic hot-spot in Lisbon, Portugal, by comparing the atmospheric pollutant concentrations obtained by a numerical model with measured values. Results indicate that the mean variation of particle and gaseous concentrations followed the traffic flow rate, evidencing the occurrence of PM10 concentrations greater than the respective air quality ...

Air pollution in Europe 1990-2004
Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate matter ...

Dust monitoring solutions for cement plants - Case Study
Particulate emissions from cement kilns have been reduced significantly over the last few decades due in part to ever-tightening regulatory controls including the lowering of emission limit values (ELVs) and the associated increase in installations of highly effective filtration systems which require higher quality monitoring. Main emissions to air are from the kiln system Additional ...

On-road tests show gas trucks up to 5 times worse for air pollution
Trucks powered by liquified natural gas (LNG) pollute the air up to five times more than diesel trucks, according to on-road tests commissioned by the Netherlands government. The results fly in the face of truckmakers’ claims that gas trucks cut nitrogen oxide (NOx) emissions by more than 30%.[1] [2] Transport & Environment (T&E), which today publishes the test results, ...

Fabricated Parts for Air Infiltration Sealing
Air leakage control is a critical activity for a wide spectrum of businesses. Contractors may be tasked with sealing building envelopes to prevent heat loss, thus energy wastage. Specialty manufacturers may be called upon to deliver precision fabricated parts that target specific pain points and air leakage paths. The only way to gain a deep understanding of where air infiltration, heat losses, ...

Planetary Boundary Layer: Why Is It Important?
The famous statistician George Box said “All models are wrong, but some are useful”—for calculating air quality indices and emissions estimates this is certainly true. One way to increase the utility of models is to use up-to-the-minute, local Planetary Boundary Layer (PBL) measurements as an input when generating top-down emissions estimates. Understanding the local PBL should ...
