When summer temperatures rise and people turn to their air conditioners to stay cool, something else also increases: air pollution.

A new study published Wednesday (May 3, 2017) in the journal Environmental Science & Technology shows that the electricity production associated with air conditioning causes emissions of sulfur dioxide, nitrogen oxides and carbon dioxide to increase by hundreds to thousands of metric tons, or 3 to 4 percent per degree Celsius (or 1.8 degrees Fahrenheit).

Even a relatively mild Zika outbreak in the United States could cost more than $183 million in medical costs and productivity losses, suggests a computational analysis led by Johns Hopkins Bloomberg School of Public Health researchers, while a more severe one could result in $1.2 billion or more in medical costs and productivity losses.

Smog from cars and trucks is an expected health hazard in big cities, but researchers from the University of Cincinnati found pollution from truck exhaust on one of the most remote mountain roads in the world.
 

James Thuch Madhier fled South Sudan as a teenager, escaping the ravages of civil war and famine.

Next fall, the U of T undergrad and his social entrepreneurship team will be testing out their solar-powered crop irrigation system on 20 acres of land they've acquired in South Sudan.

Two immune responses are important for recovery after a heart attack — an acute inflammatory response that attracts leukocyte immune cells to remove dead tissue, followed by a resolving response that allows healing.

Frequent occurrence of both anthropogenic pollution and natural dust in East Asian imposes great impact on regional air quality, human health and climate. Till now, their interaction and consequent effect on the dust morphology remain statistically unclear because even though traditional filter-based bulk sampling method can provide accurate chemical compounds, it cannot distinguish the mixing state of chemicals with dust particles.  

Black licorice. You either love it – or you hate it. But one Western researcher is offering a reason to pass the next time you think about reaching for that black licorice jelly bean, twist or whip – your health.

Cold weather increases the risk of mortality in Texas residents, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) School of Public Health. The findings were recently published in the journal Environmental Pollution.

A new study explains for the first time how nanoparticles like those in diesel exhaust fumes cause heart disease by lodging in inflamed blood vessels, writes Oliver Tickell. The study, published as the UK government is ordered before the High Court to justify its refusal to publish plans to tackle illegal air pollution which afflicts 38 million people, also raises wider fears about 'engineered nanoparticles' in the environment.

Airborne particulates on subway platforms and trains are up to 10 times higher than outside air, around three times higher than levels in Montreal’s Metro

A new study co-authored by U of T Engineering ProfessorGreg Evans shows that subways increase our personal exposure to certain pollutants, even as they decrease overall emissions – and that Toronto has the highest levels in Canada.
