  • Air quality in America

    Although most Americans tell pollsters they believe air pollution in the United States is getting worse, the reality is quite different. In 'Air Quality in America: A Dose of Reality on Air Pollution Levels, Trends, and Health Risks' (AEI Press, January 2008) environmental scientist Joel Schwartz and political scientist Steve Hayward demonstrate why air pollution has been dropping steadily for ...

  • Proactive Indoor Air Quality Surveys Save Budgets

    As facility budgets tighten, managers are realizing the many benefits that money spent for proactive indoor air quality is a smart investment. Here is a simple comparison to exemplify the point. Indoor air quality investigations conducted in response to employee complaint or illness clusters cost $3.00 to $10.00 per square foot of space investigated compared to 2 to 10 cents per square foot for a ...

  • Carbon Monoxide, Carbon Dioxide and Indoor Air Quality

    Chances are that unless you are hot or cold – or if you smell something funny – you probably never think about indoor air quality. However, scientists know that gases in the air that you cannot see or smell can still affect your health. Carbon Monoxide The most dangerous gas most of us will ever face is carbon monoxide (CO). Not normally occurring in nature, this ...

  • Air quality one of many risk factors for IVF

    Pregnancy is a complex process in the best possible scenario - two people deciding to have a baby and conceiving naturally. Even then, many things can go wrong. There is truth in sayings such as “babies are miracles.” But what if a couple just doesn’t get pregnant? According to the CDC, infertility is a common concern in North America, affecting one out of every eight couples ...

  • Micro Pulse LiDAR: A Critical Tool for Emissions Source Detection

    Micro Pulse LiDAR remote sensing data are used to calculate a highly accurate Planetary Boundary Layer (PBL) height to improve plume models that help assess emissions sources. Poor air quality is a growing health issue that has a negative impact on the quality of life for millions of people. To help alleviate this serious problem, scientists at Bubbleology Research International (BRI) have ...

  • Scientists call manmade chemicals like refrigerant gases a cause of climate change

    A major cause of climate change is the harm that is done to the Earth by man-made chemicals. Whilst chemicals, such as those used to produce day by day items, operate equipment and generally make life easier, are necessary, they present a threat to the environment. Governments around the world have set new regulations to limit the use of substances that contribute to global warming and deplete ...

  • California Air Resources Board (CARB) places higher restrictions on air pollution

    As part of the California Global Warming Solutions Act (AB 32) the Air Resources Board (ARB) has approved an early action measure to reduce high-global warming potential (GWP) greenhouse gas (GHGs) emissions by establishing new legislation and defining requirements related to improved monitoring of AC/HVAC systems, enforcement of regulations, reporting of refrigerant usage, and recovery, ...

  • 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 ...

  • Legal Lookout: EPA Staff Urges Changes in PM Standards

    Earlier this year, EPA staff scientists urged agency management to revise the current particulate matter (PM) standards for fine particles and the inhalable portion of coarse particles, based on evidence that suggests to EPA scientists that more protection is needed than is provided under current air standards. Background The Clean Air Act (CAA) requires that EPA periodically review its ...

  • Effects of air pollution on European ecosystems - Past and future exposure of European freshwater and terrestrial habitats to acidifying and eutrophying air pollutants

    Poor air quality not only harms human health; it also impacts the structure and function of ecosystems, often far away from the emission sources. This report focuses on the deposition of airborne sulphur (S) and nitrogen (N) compounds and their negative effects on ecosystems. N- and S-containing air pollutants are released to the atmosphere by combustion processes such as the burning of coal or ...

  • 7 million premature deaths annually linked to air pollution

    New estimates released earlier this year by the World health Organization (WHO) suggest that in 2012 around 7 million people died – one in eight of total global deaths – as a result of air pollution exposure. This finding more than doubles previous estimates and confirms that air pollution is now the world’s largest single environmental health risk. Reducing air pollution could ...

  • How Serious are the Issues of IAQ?

    In a recent report, UL’s scientists estimated that there are 80,000 chemicals in international commerce today, with only 3% having been fully evaluated for health impacts. The danger is exacerbated by sealing building envelopes to conserve energy and trapping some of these chemicals inside buildings. The increase in awareness of mold as a cause of human health complications has catalyzed an ...
