Can roadway design air quality impacts
In recent years, a consensus has emerged that exposure to traffic emissions increases risks of adverse health effects for populations living, working, or going to school near large roadways.1-4 Near-roadway air pollution is characterized by elevated levels of trafficgenerated compounds compared to overall urban background levels with the gradual decrease in concentrations within several hundred ...

Cumulative Air Quality Impact Assessments - A Case Study
Introduction Deregulation across the country has resulted in the proposal of hundreds of new power plants within the last several years. Each power plant, individually, is required to demonstrate conformance with state and federal air quality regulations. However, there is still a great deal of public concern over the combined or cumulative impact that all of these proposed plants may have on ...

Baseline data in air quality impact studies
The main objective of this paper is to explain not only the importance of the baseline data in air quality studies but also the general procedures and steps involved in the baseline data collection. Special considerations on the instruments and measurements for a perfect baseline data collection are also emphasized in this paper. As an example, an adequate baseline data collection procedure which ...

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 ...

Two impact related air quality indices as tools to assess the daily and long-term air pollution
The methodology of the recently developed Daily Air Quality Index (DAQx) and Long-term Air Quality Index (LAQx) is explained. Both indices consider air pollutants frequently monitored at long-term stations within official air pollution control networks. Therefore, they enable an assessment of the integral air pollution, which reflects the ambient air consisting of a mixture of air pollutants more ...

Modelling the air quality impact of industrial emissions over a valley in Southern Italy
The aim of this study is to support decision makers and stakeholders in the management of air quality in an industrial area located in a valley in southern Italy, where neither air quality nor meteorological parameters are routinely monitored. The first phase focused on the inventory of emissions through monitored data at stacks, permissions to emit from local authorities, and life cycle ...

An incinerator air quality impact assessment for metals, PAH, dioxins and furans by using the MM5-CMAQ-EMIMO atmospheric modelling system: Spain case study
In this paper, we show the implementation of a modified version of MM5-CMAQ for carrying out an air quality impact analysis for installing an incinerator in the Basque Country model domain (Spain). The modified CMAQ model (EPA USA, 2004) includes Poly-Chlorinated Dibenzop-Dioxins and Dibenzo-Furans (dioxins and furans). This model represents their congeners as divided between gaseous and aerosol ...

Assessing the local scale annual air quality impact of industrial source from characteristic days
An approach of assessing the annual air quality impact of industrial sources from results of simulations performed for characteristic days, representative for different local scale dispersion conditions, is being studied. The methodology for selecting the characteristic days is presented. For classifications with different number of similar day clusters the air–quality directive limit and target ...

Dynamic modelling of transient emissions and concentrations from traffic in street canyons
In the EU 5th framework project DECADE (2001–2003), a new methodology has been developed to calculate in detail the engine power required to drive a given vehicle over any particular route. It includes the rapidly changing (transient) demands placed on the engine, an area that has proved an obstacle to accurate simulations in the past. Together with the associated speed profiles, the actual power ...

How air pollution affects climate: short-lived climate forcers
While long-lived greenhouse gases—particularly carbon dioxide (CO2)—continue to occupy center stage in international climate negotiations, another group of pollutants has been gaining attention among scientists and policy-makers: the so-called “short-lived climate forcers,” including black carbon and ozone. These pollutants have been regulated in the United States for ...

Mortality rates and air pollution levels under different weather conditions: an example from Western Europe
According to results of the World Health Organization (WHO) high PM10 concentrations caused a reduction of the average life expectancy of 10.2 months in Germany. The objectives of this study are to determine the influence of the synoptic scale flow patterns on air pollutants and to quantify effects of air pollution on mortality rates. To describe the synoptic situation two weather type ...

Pollution survey of carbonyl compounds in train air
The train is an important vehicle in China, but its air quality has important impacts on passengers’ health. In this work, pollution from carbonyl compounds was measured in the air of six trains. The objectives of this work were to investigate carbonyl compound levels in selected air from trains, identify their emission sources, and assess the intake of carbonyl compounds for passengers. The ...

Environmental impact prediction of air quality in a food processing environment
An impact study of food processing factory in Nigeria on air quality of its environment was studied using a factorial experiment. The effects of three primary air pollutants (by-products of the food processing): nitrogen (IV) oxide (NO2), carbon (IV) oxide (CO2) and sulphur (IV) oxide (SO2) on formation of acid rain also studied. These factors and their interactions in the predictive model showed ...

How health related issues are likely to drive dispersion modelling over the next decade
In the future, the focus of dispersion modelling may centre on the aggregation of sources, atmospheric chemical reactions and longer range transport. This will put greater emphasis on the use of assimilated meteorological data as models are used to assess public policy options to minimise the impacts of air pollutants on human health and welfare. Because of the international nature of threats, ...

The air quality ripple effect: The multitude of secondary benefits from reducing air pollution
TL;DR - While air pollution’s connection to other environmental issues such as deforestation and climate change is more readily recognized, poor air quality also impacts a variety of other sectors that may not be thought of as environmentally-tied, such as tourism and real estate. By recognizing the complex web of effects that air quality has on environmental and non-environmental sectors ...

Science and policy challenges of atmospheric modelling in consideration of health effects
Next generation atmospheric models are required to provide a realistic assessment of different types of chronic and acute environmental conditions and forecast the consequences on population health. These tasks were usually carried out with epidemiological studies, which are not adequate to indicate health effects. Therefore, models should be capable to carry out hazard identification, ...

Measurements and Standards to Support Increased Energy Efficiency and Reduced Environmental Impact
“The world is facing twin energy-related threats: that of not having adequate and secure supplies of energy at affordable prices and that of environmental harm caused by consuming too much of it.” Daniel Hecker, economist, Bureau of Labor Statistics, July 2005 Buildings in the U.S. consume 72 percent of all electrical energy produced in this country. Emissions associated with ...

Setting up a regulatory frame for atmospheric dispersion modelling in Italy: needs, actors and ongoing activities
The need for regulatory models for predicting the impact of atmospheric emissions, both for Environmental Impact Assessment (EIA) studies and in the frame of Air Quality Management Plans (AQMP), is well known to the Italian technical-scientific community, and is acknowledged also by decision makers. Some specific features of the Italian territory, e.g. complex orography, land-sea discontinuity ...
