It contributes to climate change. And a primary source in Louisville and other cities is traffic exhaust.</p><p>This week, WFPL took an in-depth look at black carbon—where it's found and how it affects Louisville and beyond.&nbsp;In a project that took months of preparation, environment reporter Erica Peterson relied on air monitors and interviews with experts and community members.&nbsp;</p> Sun, 03 Nov 2013 12:00:00 +0000 Joseph Lord 7418 at http://wfpl.org Black Carbon Series: How Traffic Exhaust Affects Climate Change and Louisville's Health In Black Carbon, Scientists Find a Major Source Behind Climate Change http://wfpl.org/post/black-carbon-scientists-find-major-source-behind-climate-change <p>Climate change is mainly caused by greenhouse gases, such as carbon dioxide. And the gases mainly come from sources like power plants and vehicle emissions. But scientists have found another major threat to the climate: black carbon particles from wood fires, diesel engines and practically everything else that's burned.</p><p>Carbon dioxide has long been the villain behind climate change. That's still the case, but new research suggests CO2 has a sidekick—black carbon.</p> Fri, 01 Nov 2013 10:34:17 +0000 Erica Peterson 7395 at http://wfpl.org In Black Carbon, Scientists Find a Major Source Behind Climate Change What Walks Through Louisville Reveal About Black Carbon Exposure http://wfpl.org/post/what-walks-through-louisville-reveal-about-black-carbon-exposure <p>In Louisville, a city bisected and ringed by interstate highways and in the midst of expanding its concrete infrastructure, it’s hard to get away from traffic pollution. Every day, cars and trucks belch out cocktails of gases and chemicals, such as arsenic, nitrogen dioxide and fine particles.</p> Thu, 31 Oct 2013 10:43:46 +0000 Erica Peterson 7383 at http://wfpl.org What Walks Through Louisville Reveal About Black Carbon Exposure What Louisville Neighborhoods Are Affected by Traffic Exhaust? All of Them. http://wfpl.org/post/what-louisville-neighborhoods-are-affected-traffic-exhaust-all-them <p><span style="line-height: 1.5;">Louisville has always struggled with air pollution—from industrial parks and from the traffic-clogged highways. But while Metro Government's network of air monitors tests the air around the city, it’s harder to tell what residents are actually exposed to in their homes.</span></p><p>In the Portland neighborhood, I-64 rumbles past rows of shotgun houses, many with siding made grimy by the traffic exhaust. The highway is loud and dirty, but its pollution isn’t the primary concern for many residents.</p> Wed, 30 Oct 2013 10:33:04 +0000 Erica Peterson 7369 at http://wfpl.org What Louisville Neighborhoods Are Affected by Traffic Exhaust?
