Another reason we need fewer, smaller and lighter cars: Tire, brake and road wear is proportional to the weight of vehicles. Brake, tire and road surface wear are 60% of emissions for particles 2.5 mm diameter, and 73% of 10 mm particles

When measured by volume of emission, tire, brake and road wear from vehicles is the second largest contributor to microplastic pollution worldwide. The tires on your car are made from a complex blend of different materials and chemicals including several types of plastic in addition to their rubber base. As vehicles are driven, the friction, pressure and heat caused from …

White people cause the most pollution, but people of color suffer the most from it

Poor air quality contributes to 63% of all deaths caused by environmental factors. In a newly released study, they show that in the U.S., fine particulate matter air pollution “is disproportionately caused by consumption of goods and services mainly by the non-Hispanic white majority, but disproportionately inhaled by black and Hispanic minorities.” White people in America, on average, breathe in around …

Depression, bipolar, and schizophrenia are higher in areas with worse air quality

With more specific Danish data, the team found early childhood exposures correlated even more strongly with major depression (a 50 percent increase); with schizophrenia (a 148 percent increase); and with personality disorders (a 162 percent increase) over individuals who grew up in areas with the highest quality air. In research on animals exposed to pollution, the animals show signs of …

People in Poor Neighborhoods Breathe More Hazardous Particles

Tiny particles of air pollution contain more hazardous ingredients in nonwhite and low-income communities than in affluent white ones, a new study shows By Cheryl Katz, Environmental Health News, Scientific American, November 1, 2012 Tiny particles of air pollution contain more hazardous ingredients in non-white and low-income communities than in affluent white ones, a new study shows. The greater the concentration of Hispanics, …

Oil and Gas Emissions a Major Contributor to Bad Ozone Days: Colorado’s northern Front Range focus of new study

Oil and Gas Emissions a Major Contributor to Bad Ozone Days: Colorado’s northern Front Range focus of new study FRIDAY, NOVEMBER 3, 2017 “The high ozone levels we observed on days when oil and gas activity was a primary contributor underscore the importance of better quantifying the contribution from oil and gas operations,” Cheadle said. “That understanding could support strategies …

Health care is a human right, and we shouldn’t have to worry about whether we can breathe the air here in Colorado, day by day

Diana Bray@Diana4Colorado Special to The Colorado Sun See more Sometimes you just have to take a leap into the unknown when you see that the status quo is simply not working.  In 1935, President Franklin D. Roosevelt did just that when he signed Social Security into law. In 1965, President Lyndon Johnson did the same with Medicare, which provides health …

Cornell University study indicates US fracking is responsible for over half of the sizeable rise in global methane emissions between 2008 and 2014

David Roberts, Vox, Aug 2019. Methane doesn’t stay in the atmosphere as long as CO2 and is reabsorbed into terrestrial cycles via chemical reactions within 12 years or so. But while it’s up there, it’s much more potent, trapping heat at roughly 84 times the rate of CO2. Scientists estimate that around 25 percent of current global warming traces to methane. 63 percent of …

Democratic Candidates Flake on Detroit Environmental Justice Forum

Seats sit empty for candidates who cancelled on a July 31 educational forum about Detroit’s most polluted ZIP code, convened by Frontline Detroit, Climate Justice Alliance and other environmental justice activists. (Still courtesy of Climate Justice Alliance) In These Times, Aug 9 2019 Most candidates tout a just transition for “frontline communities” like Detroit, but only Jay Inslee showed up …

Long-term exposure to ground level ozone is like smoking a pack of cigarettes a day. Just a slightly elevated level of air pollution can lead to lung damage, even for people who have never smoked.

Aug 2019 It turns out you don’t need to smoke for a lifetime to get emphysema. Just breathing polluted air can give it to you, according to a new study that is the largest and the longest of its kind. “We found that an increase of about three parts per billion [of ground-level ozone] outside your home was equivalent to smoking a pack of …

Climate Change Worsens Air Quality

In 2013, when Beijing and other cities in China faced a pollution-filled haze dubbed the “airpocalypse,” scientists pointed to stagnant air conditions as contributing to the air pollution accumulation. In parts of heavily populated eastern China, the mountains help create conditions that make it easier for haze to sit in cities when high pressure systems and high humidity affect the region. The new study …
