  • Air quality specialist calls for black carbon standard

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, Jim Mills, Managing Director of Air Monitors, believes that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Black Carbon (BC) is a term describing the fine particles that are produced as the result of incomplete combustion of fuels and ...

  • EPA strengthens air quality standard for nitrogen dioxide

    The U.S. Environmental Protection Agency today announced a new national air quality standard for nitrogen dioxide (NO2). This new one-hour standard will protect millions of Americans from peak short-term exposures, which primarily occur near major roads. Short-term exposures to NO2 have been linked to impaired lung function and increased respiratory infections, especially in people with asthma. ...

  • EPA Hearings Seek Public Input on Stronger Proposed Air Quality Standards

    EPA will hold five public hearings to receive comment on the agency's proposed revisions to the national air quality standards for ground level-ozone. In June, EPA proposed to strengthen the standards, recommending a standard within a range of 0.070 to 0.075 parts per million (ppm). The current standard is 0.08 ppm. ...

  • EPA to hold public hearing on air quality standards for carbon monoxide

    The U.S. Environmental Protection Agency (EPA) will hold a public hearing Feb. 28 on the agency’s proposal to retain the nation’s air quality standards for carbon monoxide (CO) and to take steps to gather additional data through more focused monitoring.

  • EPA sets public hearing dates on air quality standards for nitrogen dioxide

    EPA will hold two public hearings on the agency’s proposal to strengthen the nation’s nitrogen dioxide (NO2) standards. The proposed revisions would establish, for the first time, a one-hour NO2 standard, at a level between 80 and 100 parts per billion (ppb) and would retain the current annual standard of 53 ppb. The proposed changes reflect the latest science on the health effects of exposure to ...

  • EPA to hold public hearings on air quality standards for smog

    The U.S. Environmental Protection Agency will hold three public hearings on the proposal to strengthen the nation’s air quality standards for ground-level ozone, also called smog. Exposure to smog is linked to a number of serious health problems, ranging from aggravation of asthma to increased risk of premature death in people with heart or lung disease. The agency is proposing to set the ...

  • EPA proposes stronger air quality standards for sulfur dioxide

    For the first time in nearly 40 years, EPA is proposing to strengthen the nation’s sulfur dioxide (SO2) air quality standard to protect public health. Power plants and other industrial facilities emit SO2 directly into the air. Exposure to SO2 can aggravate asthma, cause respiratory difficulties, and result in emergency room visits and hospitalization. People with asthma, children, and the ...

  • US brings in stringent new air quality standard to protect public health

    The US Environmental Protection Agency has introduced its most stringent 8-hour standard ever for ozone, revising the standards for the first time in more than a decade. The agency said it based the changes on the most recent scientific evidence about the effects of ozone, the primary component of smog. “America’s air is cleaner today than it was a generation ago. By meeting the requirement of ...

  • US air quality control standards for lead now 10 times stronger

    EPA dramatically strengthened the nation's air quality standards for lead, improving public health protection, especially for children. The new standards tighten the allowable lead level 10 times to 0.15 micrograms of lead per cubic meter of air (ug/m3). 'America's air is cleaner than a generation ago,' said EPA Administrator Stephen L. Johnson. 'With these stronger standards a new generation of ...

  • EPA announces most areas meet air quality standards for lead

    The U.S. Environmental Protection Agency (EPA) has determined that available air quality information indicates that 39 states are meeting the health-based national air quality standards for lead set in 2008. Based on 2008 to 2010 air quality monitoring data, EPA also determined that Illinois, Iowa, Kansas, Michigan and Puerto Rico each have one area that does not meet the agency’s health ...
