Abstract: Current literature is insufficient to make causal inferences or establish dose-response relationships for traffic-related ultrafine particles (UFPs) and cardiovascular (CV) health. The Community Assessment of Freeway Exposure and Health (CAFEH) is a cross-sectional study of the relationship between UFP and biomarkers of CV risk. CAFEH uses a community-based participatory research framework that partners university researchers with community groups and residents. Our central hypothesis is that chronic exposure to UFP is associated with changes in biomarkers.

As recently as 20 years ago, there were an estimated 50,000 rivers in China, each covering a flow area of at least 60 square miles. But now, according to China's First National Census of Water, more than 28,000 of these rivers are missing. To put this number into context, China's lost rivers are almost equivalent, in terms of basin area, to the United States losing the entire Mississippi River. Why have these rivers "vanished" from the maps and national records?

China's environmental situation is frequently scrutinized both within China and across the world. In the second half of a two-part podcast Angel Hsu, a China expert completing her PhD this May at the Yale School of Forestry and Environmental Studies, discusses urbanization in China and India and China's push to develop sustainable ecocities.

Low-income neighborhoods are more often exposed to poor environmental quality when compared to wealthier communities, and scientists are saying this gap will increase as climate change is more widely felt.
