Race/ethnic disparities in cumulative impacts

Study: non-whites more exposed to environmental hazards. Brooks Hays, UPI, September 17, 2015. According to a new study, published in the American Journal of Public Health, African Americans and Hispanics are more exposed to health risks like air pollution, toxic waste and a lack of green space. Risk exposure for Hispanics was 6.2 times higher than whites, and 5.8 times higher for African Americans.

Information plus organizing to make real change

Community-based participatory science is changing the way research happens -- and what happens next. Judy Robinson, The Equation, September 9, 2015. In both the dollar store research and the oil and gas science, the effect of the science was to strengthen existing organizing campaigns for community-based solutions. The "good old days" when we waited for scientific proof to change the world are over, if they ever existed. Now science and citizen organizing together are changing the rules of the game, the outcome, and who gets to play.

Cancer risk to California Residents from Air Contaminants

Ambient and Emission Trends of Toxic Air Contaminants in California. Ralph Propper, Patrick Wong, Son Bui, Jeff Austin, William Vance, Alvaro Alvarado, Bart Croes, and Dongmin Luo, Environmental Science & Technology, September 4, 2015. The collective cancer risk from exposure to these seven reviewed toxic air contaminants [benzene, 1,3-butadiene, perchloroethylene, hexavalent chromium, diesel particulate matter, formaldehyde and acetaldehyde] declined 76%. Significant reduction in cancer risk to California residents from implementation of air toxics controls (especially for diesel particulate matter) is expected to continue.

Certain properties of environmental contaminates increase fetus vulnerability and exposure

Fetuses more vulnerable to some environmental contaminants penetrating into cord blood. Medical Xpress. June 26, 2015. A new research featured in the Environmental Science and Technology published by the American Chemical Society suggests that the fetus is more vulnerable to some pollutants with certain properties because they penetrate further into the feto-maternal system.

The Great Barrier Reef is in peril: Federal and Queensland governments must get serious

Development and the Reef: the rules have been lax for too long. Bob Pressey, Alana Grech, Jon C. Day, and Marcus Sheaves, The Conversation. May 28, 2015. Through coastal development, people have changed the Reef's coastal zone dramatically, and the direct result is the decline of the Reef's ecosystems. No single development has tipped the balance, but a litany of poor choices has resulted in a tyranny of small decisions, with a large cumulative impact.
