|SAN FRANCISCO Francisco Lindor Indians Jersey , Sept. 18 (Xinhua) -- A new study finds that the United States made little progress from 2000 to 2010 in reducing relative disparities between people of color and whites in exposure to harmful air pollution emitted by cars, trucks and other combustion sources.
The study builds on the work led by University of Washington (UW) researchers in both 2000 and 2010, identifying that disparities in exposure to outdoor concentrations of a transportation-related pollutant, namely nitrogen dioxide (NO2), were larger by race and ethnicity than by income, age or education.
The relative inequality persisted across the decade.
For the study Edwin Encarnacion Indians Jersey , published in the recent issue of Environmental Health Perspectives, the researchers developed a first-of-its-kind model that combines satellite and regulatory measurements with land use data to predict pollution at a neighborhood level throughout the United States.
Measured in parts per billion (ppb), estimated average annual NO2 exposure decreased from 17.6 to 10.7 ppb for nonwhite populations, and from 12.6 to 7.8 ppb for white populations.
Yet people of color were, on average, consistently exposed to more air pollution than their white non-Hispanic counterparts during the decade. Considering relative differences Joe Carter Indians Jersey , nonwhites experienced 40 percent higher exposures than whites in 2000; in 2010, that gap shrunk slightly, to 37 percent. Furthermore, in 2000, concentrations of NO2 in neighborhoods with the highest proportion of nonwhite residents were 2.5 times higher than in neighborhoods with the lowest proportion of nonwhite residents. In 2010, that value increased slightly Corey Kluber Youth Jersey , to 2.7 times higher.
The study concludes that if people of color had breathed the lower NO2 levels experienced by whites in 2010, it would have prevented an estimated 5,000 premature deaths from heart disease among the nonwhite group.
On the whole, the researchers noted, policies to reduce NO2 air pollution are working across the United States. But the finding that exposure differences are larger by race and ethnicity than by income, age or education was equally true in 2010 as in 2000.
"Everyone benefited from clean air regulations and less pollution; that's the good news Jason Kipnis Youth Jersey ," lead author and UW civil and environmental engineering doctoral student Lara Clark, was quoted as saying in a news release from UW. "But the fact that there is a pervasive gap in exposure to NO2 by race - and that the relative gap was more or less preserved over a decade - is the bad news."
NO2, which has been linked to asthma symptoms, increased susceptibility to respiratory problems and heart disease, comes from sources such as vehicle exhaust, power plants and off-road equipment and is one of six important "criteria air pollutants" monitored by the U.S. Environmental Protection Agency (EPA).

ZAGREB Francisco Lindor Youth Jersey , Sept. 14 (Xinhua) -- In Croatia, the southeastern European country where one of the greatest minds in the history was born, there is another man who is changing the auto industry right now.
Mate Rimac is just 29, and people call him the next Nikola Tesla, a Serbian-American inventor (1870-1873) because his company makes the fastest electric hyper cars and provide battery technology for big names of auto industry like Koenigsegg.
"I can't compare myself to him. I was reading a lot about him because he was from Croatia and I was fascinated by the electric motor that he had invented. We do a lot of interesting things here but our achievements cannot even remotely be compared to his", a modest Mate Rimac said during an exclusive interview with Xinhua.
Rimac showed his creativeness as a teenager Edwin Encarnacion Youth Jersey , winning numerous awards from technological invention contests in many countries. As a young man crazy about cars finally got some money by a patent he held. He bought a BMW and became a passionate street racer but ended up blowing up the engine during a race. And that was when he decided to build an electric race car. "I'm crazy about cars all my life and I wanted to prove that cars can be fun and fast when they are electric," Rimac told Xinhua.
In 2009, the newly founded company Rimac Automobili was indeed a typical start-up with less than ten employees. In just two years, a group of brilliant minds that started from scratch managed to produce the world's first all-electric hyper car, the Concept One. It was the fastest accelerating electric car in the world. They did it all by themselves. From the motor and battery pack to exterior design and infotainment system.
The car was introduced at the 2011 Frankfurt Motor Show and so far, they manufactured a limited quantity of only ten cars Joe Carter Youth Jersey , which is understandable concerning the price tag of over one million U.S. dollars. In 2016 the company unleashed its "evil twin", even faster Concept S. Top speed of the car is 365 kmh and it accelerates from zero to 100 kmh in just 2.5 seconds.
"Cars are very important for us but they are more of a showcase of what we can do. They are showing to other companies what our technology can achieve. They are our billboard", Rimac claims. He explains that making cars is a very difficult business in which many people bankrupted even before they produced their first car.
"It is a school example of the industry with the highest entry barriers, so it is a big step to get into it. If you look the U.S., for example, the only new car company in the last 60 years is Tesla. If you look at other car companies in the world Corey Kluber Womens Jersey , like Volkswagen, Porsche or Mercedes these companies are 60, 70 or 100 years old, have thousands of employees and the budget bigger than our country's budget. The total GDP of Croatia is three times smaller than Volkswagen revenue", he explained why he chose the high-end market.
"It's very unrealistic to start immediately with big numbers and small price. The
