An evaluation of air pollution at the Bily Kriz mountains in the Czech Republic is given. Annual daily concentrations of sulphur dioxide (SO2), nitrogen oxides (NOx), particulate matter of size 10 mm (PM10) and ozone (O3) measured in the years 1994–2000 are presented. Air pollution at Bily Kriz is assessed with the reference to the European Union Directives and the standards adopted by the Czech Republic. In general, the concentrations of air pollutants were lower in 1996 for ozone and decreased for SO2, NOx and PM10 from 1994. The daily values of SO2 and PM10 exceeded the European Union limits in approximately 0.0% and 5.5% of cases, respectively. The values of ozone exceeded the limits for the considered period.

IMPLEMENTATION OF THE FIRST DAUGHTER DIRECTIVE
ON AMBIENT AIR QUALITY IN EUROPE
INTRODUCTION AND EXECUTIVE SUMMARY
This publication analyses the quality of national implementation of the first Air Quality Daughter Directive
(1999/30/EC). The report is based on information from 15 NGOs (members of the EEB’s Clean Air Working
Group), who provided data for PM10 concentrations in ambient air as well as information about air quality
management plans from 30 cities in...
This report explores the linkages between air quality and climate change from a European perspective in order to assist the European Environment Agency (EEA) in approaching the issues of air quality and climate change in an integrated way. The report addresses the linkages between air pollution and climate change by:
(1) collecting and summarising existing information from the literature on linkages between air pollution and climate change;
(2) identifying gaps in current knowledge on linkages between...
DG Environment has had prepared the Benefits Table (BeTa) database of externalities for air pollution in Europe. BeTa gives the marginal external costs of air pollution (SO2, NOx, VOCs and PM10) in terms of euros per ton of pollutant for each EU Member State. Furthermore, these external costs are divided between rural and urban areas. Finally, preliminary estimates of the externalities from shipping are given for the Eastern Atlantic, Baltic Sea, English Channel, Northern Mediterranean, and North Sea.

Life cycle impact assessment is usually plagued by the assumptions of site independence and uniform mixing of pollutants in a compartment (e.g., atmosphere), which are not valid for all air pollutants. In this paper we propose using the concept of exposure efficiency to simplify the damage pathway analysis without compromising the consideration of site-dependent characteristics. Our case study of increasing insulation in new homes in the US from the MEC1993 to IECC2000 level yields 6,442 TJ (6,111 GBTU) of energy...
Editor’s Note: Part l of this two-part feature on wet electrostatic precipitation (wet ESPs) outlines the need for multi-pollutant air pollution control technologies, the basics of wet and dry electrostatic precipitation, the ability of wet and dry ESPs to treat fine particulate, and the use of wet ESP technology at Northern States Power Company’s Sherco Station.
Part II will explore the key design considerations associated with wet ESP technology, compare plate and tube-type configurations, and examine the use...
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 ), particulate matter less than 2.5 microns in aerodynamic diameter (PM2.5), and lead (Pb). In addition, estimates of...
ABSTRACT
Roy F. Weston, Inc. (WESTON®) has designed an indirect thermal desorption process (known as the LT3-HT) to treat solids and sludges contaminated with hazardous and toxic materials. The LT3-HT is a high-temperature, high-capacity thermal desorption system designed for treatment of semivolatile and volatile organic contaminants that require high treatment temperatures. The LT3-HT includes WESTON’s original and patented thermal desorption technology to dry the feed material, via indirect heat transfer,...
Biofilters are the odor control system of choice at composting facilities. Despite similar capital costs, the biofilters are generally less costly to operate than chemical scrubbers. The key to keeping operating costs in check, however, is to get the maximum use out of the biofilter media, thus avoiding the time and money needed to do media replacements.
Allen Boyette, senior engineer and manager of the Cary, North Carolina office of E&A Environmental Consultants, Inc., tackled the topic, “Building Longevity...
Measuring and valuing the health impacts of pollution are very complex and available methods of economic analysis are often rudimentary. In recent years, considerable progress has been made, especially in respect to air pollution. This note summarizes the latest findings and outlines some basic approaches that can be applied in the economic analysis of Bank projects and sector studies. However, a degree of uncertainty still remains, and great care must be taken in their application.

` Comparative risk assessment provides a systematic way to compare environmental problems that pose different types and degrees of health risk. It combines information on the inherent hazards of pollutants, exposure levels and population characteristics to predict the resulting health effects. Using data from available sources, rapid, inexpensive comparative risk assessments can identify the most significant health problems. Together with consideration of costs, technical feasibility and other factors, the...
Different kinds of environmental standards can serve quite different purposes in environmental policy. This note outlines these differences
Ambient Standards
Ambient standards set maximum allowable levels of a pollutant in the receiving medium (air, water and soil). Ambient standards can offer a simple method of establishing priorities since areas (or stream lengths) which comply with the relevant ambient standards are considered to require no further intervention, while other areas may be ranked by the extent...
The proliferation of bottled beverages worldwide and an increased awareness of consumer health issues have beverage bottlers rethinking how to keep their liquids safe for consumption. One problem they face is the need to deliver a product that is free of bacteria, to provide extended shelf life and product quality.
Ozone has quickly become the disinfectant of choice among water bottlers worldwide. Although ozone was `discovered` in the mid-19th century, it is only during the last several decades that its...
Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined.
Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and nature. Human activity can add to, modify, and enhance and reduce the intensity of these fields. Furthermore, changes in...
Abstract This paper presents data on the source of PCDDs/PCDFs in cement plant stack emissions, demonstrating that these emissions are not necessarily all created by the process. The data potentially demonstrates that some of the PCDDs/PCDFs in the emissions are pre-existing dioxins and furans that are vaporized out of the kiln raw feed. This calls into question the assumption that PCDD/PCDF emissions can be decreased below a certain point. The EPA has acknowledged resuspended PCDD/PCDF emissions, such as from...
Benefits of the CFC Phaseout
The CFC phaseout is already producing benefits for the environment, businesses, and individuals. This fact sheet explains some of these benefits. Several case studies of successful conversions to alternatives are listed also.
Protection of the Ozone LayerThe chlorofluorocarbon (CFC) production phaseout is an important turning point in the recovery of the ozone layer. Currently, we are experiencing depletion of approximately 5 percent at mid-latitudes, but if no action had been...
