Fine particulate matter air pollution (PM 2.5 ) may be associated with blood vessel damage and inflammation among young, healthy adults, according to new research in Circulation Research , an American Heart Association journal. Air pollution is known to contribute to cardiovascular disease and related deaths. —Pope et al.
The American Lung Association released its annual report on air quality, State of the Air 2011 , which includes lists of the nation’s most polluted metropolitan areas. million people—live in areas with levels of ozone and/or particle pollution that are often dangerous to breathe. Bakersfield, Calif.
The Transit Authority of River City (TARC), serving the Greater Louisville area, has begun adding six new all-electric Proterra buses along the Fourth Street corridor between downtown and Iroquois Park, stopping at some of the city’s most popular destinations. They replaced high polluting trolley buses on fare-free downtown circulator routes.
The nine green zones are located in population-dense neighborhoods most affected by air pollution. Each of the zones have a large presence of traffic that is contributing to a high rate of air pollution. Boston, Louisville, Montreal, Nashville, and Seattle are using Series-ER technology to cut down emissions.
In what the city is calling a national first, Louisville, Colorado officials held a “ribbon cutting” last Tuesday to celebrate the launch of a new, all-electric residential recycling and waste collection fleet, which is already the city’s streets. As for the trucks themselves, the Louisville fleet includes four McNeilus Volterra ZSLs.

Established under the Moving Ahead for Progress in the 21st Century Act (MAP-21), the LoNo program focuses on deploying the cleanest and most energy-efficient US-made transit buses designed to cut CO 2 and criteria pollutant emissions. Grants from the LoNo program help transit agencies integrate more of these advanced buses into their fleets.
The objections they raised for years -- "no one is interested, no one would plug in, the technology is too complex, the benefits are minimal, its just shifting the pollution from the tailpipe to the smokestack, theres no demand for these cars" -- still show up occasionally, but are by and large history.
