Media invitation: Human Exposure to Indoor Air Pollution - New Research reveals Higher Risks than previously thought
September 08, 2003Who?
European Commission - Joint Research Centre
Institute for Health and Consumer Protection
What?
Presentation of the latest studies on indoor air pollution impacting on human health and an on-site visit to the JRC's unique Indoortron environmental cham-ber. Plus access to leading experts on the occasion of the 13th Annual Confer-ence of the International Society of Exposure Analysis (ISEA), (see below).
When?
22nd September, 2003.
Where?
Palazzo Congressi in Stresa, Lago Maggiore, Italy - press conference
Joint Research Centre, Ispra - on-site visit & practical demonstration.
Do we really know what we are breathing? The latest human exposure assessment studies reveal that the indoor environment poses its own threats of discomfort to health and, in some cases, can be at least twice as polluting as outdoor levels. Hundreds of volatile components have been detected and some of them are known to be toxic, mutagenic or carcinogenic while the number of sources is enormous.
What's new? On 22 September next, the European Commission's Joint Research Centre (JRC) will present to media via concrete presentations, on-site visits and practical demonstrations the results of its latest assessments. This will include in-sights into potential causes of acute indoor symptoms such as allergies, asthma, mucous irritation, headaches and tiredness. It is estimated, for example, that up to 20% of the population suffers from asthma and other allergic diseases caused by substances typically present in indoor environments.
What's on offer?
Participating journalists are invited to attend the opening address of the ISEA Conference, bringing together an expected 500 experts in health and environment issues such as air pollution, pesticides and heavy metals. The press conference on "Human Exposure to In-door Air Pollution" will include a useful overview of the new EU Public Health Programme and the JRC's key role in the INDEX (Critical Appraisal of the Setting and Implementation of Indoor Exposure Limits in the EU) and THADE (Towards healthy air in dwellings in Europe) projects. Following an interactive media-expert lunch, journalists will be taken on-site to see how this research actually works in practice at the Indoortron facility where a wide variety of leading air-related experiments are conducted. This will include demonstra-tions of new analytical advanced methods giving us, for the first time, a fingerprint of chemical species present in dangerous Volatile Organic Compounds.
Background
It is generally perceived that buildings shelter us from most unpleasant and unhealthy outdoor conditions or pollutants. We spend, on average, 85-90% of our time indoors at home, in school, at work or during recreation. However, reductions in ventilation rate to conserve energy and extensive use of new building materials are releasing chemical compounds with unknown toxicological properties. Volatile Organic Compounds (VOCs) are now a major source of air pollution in Europe.
Results from the few measuring campaigns that have been carried out are contributing to a growing awareness about the health impacts of VOC concentrations existing in indoor and outdoor air. This is increasingly associated with serious health problems. In addition, indoor pollutants such as Environmental Tobacco Smoke, radon, asbestos and benzene may substantially contribute to the increase of incidents of cancer in the population. In the case of benzene and formaldehyde, for example, the European citizen's overall indoor exposure is at least twice that one would expect outdoors.
What is being done?
Faced with a clear lack of reliable data at the European level, the JRC's Institute for Health & Consumer Protection (http://ihcp.jrc.cec.eu.int/) is developing new analytical ap-proaches, developing comparison and harmonisation methods, and conducting monitoring surveys around the Member States to quantify contaminants. This is central to providing sound data as the basis for further exposure assessment.
The 30-m3 Indoortron facility at Ispra forms the lynchpin of this strategy, providing a highly controlled environment where air composition can accurately be measured and adjusted, without any influences from the surrounding atmosphere. It enables, for example, re-searchers to study consumer products such as paints or photocopying machines and de-termine their release dynamics, to create test models that predict pollutant concentrations, to evaluate the efficiency of air-cleaning devices and to carry out exposure measurement and assessment studies. The laboratory also incorporates a control room equipped with a state of the art computer system for remote manipulation of climatic parameters and the continuous acquisition and processing of data.

The Internet contains vast amounts of information, much of it unorganized. But what you see online at any given moment is just a snapshot of the Web as a whole -- many pages change rapidly or disappear completely, and the old data gets lost forever.
Smokers see decline in ability to smell, rise in laryngitis, and upper airway issues
As Americans prepare for a day without cigarettes and tobacco products as part of the American Cancer Society Great American Smokeout (R) (November 20), new research gives them more reasons to extend that break to a lifetime.
Lichens function as indicators of nitrogen pollution in forests
Scientists have found lichens can give insight into nitrogen air pollution effects on Sierra Nevada and San Bernardino mountain ecosystems, and protecting them provides safeguards for less sensitive species.
Pollution, everyday allergens, may be sources of laryngitis
Everyday exposure to environmental tobacco smoke, allergens, and air pollution may be the root of chronic cases of laryngitis, says new research presented at the 2008 American Academy of Otolaryngology - Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO in Chicago, IL.
Fuel Emissions From Marine Vessels Remain a Global Concern
Marine vessels are no longer resting in a safe harbor. The forecast for clear skies and smooth sailing for oceanic vessels has been impeded by worldwide concerns of their significant contributions to air pollution and greenhouse gas emissions that impact the Earth's climate.
Tracking Down the Menace in Mexico City Smog
A new report by scientists who are part of the international MILAGRO Campaign indicates that some of the most harmful air pollution in Mexico City may not come from motor vehicles but instead originates with industrial sources - and that the culprit may be garbage incineration.
Dirty air brings rain -- then again, maybe not
An international team of scientists, headed by Prof. Daniel Rosenfeld of the Institute of Earth Sciences at the Hebrew University of Jerusalem, has come up with a surprising finding to the disputed issue of whether air pollution increases or decreases rainfall. The conclusion: both can be true, depending on local environmental conditions.
Global survey highlights need for cancer prevention campaigns to correct misbeliefs
Many people hold mistaken beliefs about what causes cancer, tending to inflate the threat from environmental factors that have relatively little impact while minimizing the hazards of behaviours well established as cancer risk factors, according to the first global survey on the topic.
Many U.S. Public Schools in 'Air Pollution Danger Zone'
One in three U.S. public schools are in the "air pollution danger zone," according to new research from the University of Cincinnati (UC).
