WASHINGTON, D.C.—Exposure to air pollution in the womb may be detrimental to children's brains and may contribute to slower processing speeds and behavioral problems, including attention deficit hyperactivity disorder (ADHD), according to a new study. The study, published in the journal JAMA Psychiatry, focused on polycyclic aromatic hydrocarbons (PAHs), common toxic air pollutants caused by common sources such as smoking and vehicle emissions. PAHs can cross the placenta and affect an unborn child's brain. Animal experiments showed prenatal exposure can impair behavior and learning, the researchers, from Children's Hospital Los Angeles (CHLA) and Columbia University, reported. Read more

PARIS—The indoor air quality in nursing homes can have a serious effect on the lung health of older residents, according to the findings of a new European study. The researchers, from several universities, collected data on five indoor air pollutants: PM10, PM0.1, formaldehyde, NO2 and O3. The pollutants come from a variety of sources, including heaters, building materials, furniture, cleaning products, disinfectants and cooling systems. They assessed levels of the pollutants in 50 different nursing homes in seven countries: Belgium, Denmark, France, Greece, Italy, Poland and Sweden. A total of 600 nursing home residents took part in the study. The results showed that exposure to high levels of PM10 and NO2 was significantly associated with breathlessness and cough. In addition, high levels of PM0.1 were associated with wheezing, and high concentrations of formaldehyde were linked with chronic obstructive pulmonary disease (COPD). The associations were seen with even "moderate" concentrations of indoor air pollutants, the researchers said. The study is published in European Respiratory Journal. Read More

Reasons to Breathe Easier About Bad Air PDF Print E-mail

WASHINGTON—The air above the U.S. is becoming cleaner, and voters want action to make it even more so. U.S. voters strongly want action by the Environmental Protection Agency (EPA) to limit carbon pollution from power plants. According to a new survey conducted for the Sierra Club, around 70% of respondents support strong carbon pollution limits on power plants. The survey of 1,000 voters also found strong support among voters for moving away from coal and other dirty fuels and a preference for investing in clean energy. Total releases of toxic chemicals decreased 12% from 2011-2012, according to the U.S. Environmental Protection Agency’s (EPA) annual Toxics Release Inventory (TRI) report released this week. The decrease includes an 8% decline in total toxic air releases, primarily due to reductions in hazardous air pollutant (HAP) emissions. "People deserve to know what toxic chemicals are being used and released in their backyards, and what companies are doing to prevent pollution," said EPA administrator Gina McCarthy.   Read more

Seven million people died as a result of air pollution in 2012, the World Health Organization estimates.

Its findings suggest a link between air pollution and heart disease, respiratory problems and cancer.

One in eight global deaths were linked with air pollution, making it "the world's largest single environmental health risk", the WHO said.

Nearly six million of the deaths had been in South East Asia and the WHO's Western Pacific region, it found.

The WHO said about 3.3 million people had died as a result of indoor air pollution and 2.6 million deaths were related to outdoor air pollution, mainly in low- and middle-income countries in those regions.

Chicago bans indoor electronic cigarette smoking PDF Print E-mail

from Chicago Tribune News

E-cigarettes will join regular smokes and other tobacco products as forbidden in most indoor public places in Chicago after aldermen today passed a measure backed by Mayor Rahm Emanuel to restrict where electronic cigarettes can be used and how they can be sold.

The ordinance, which passed 45-4 after opponents took one last chance to voice their displeasure, will prohibit people from using e-cigarettes in restaurants, bars and most other indoor public places in the city. The measure also will require retailers to sell e-cigarettes from behind the counter so it’s harder for minors to get their hands on them.  Read more
