Ship emissions responsible for thousands of premature deaths in China’s Pearl River Delta

Ship emissions caused more than 1,200 ozone-related and 2,500 particulate-related premature deaths in the Pearl River Delta region in 2015, according to new research in the AGU journal GeoHealth. The new study also predicts that implementing new coastal emission controls could reduce mortality due to fine particulates by 30 percent and ozone by 10 percent by 2030.

Fort McMurray homes have normal levels of indoor toxic substances following wildfire, new study reveals

Researchers have examined dust from homes in Fort McMurray in Canada for evidence of harmful toxins left in the aftermath of the devastating 2016 wildfire. Their study reveals normal levels of contaminants that are comparable to homes across Canada, and so far, no evidence of long-term health risks from fire-ash exposure in residents’ homes

Consumer purchasing data shows locals’ response to water contamination

Supermarket purchases show scientists how communities respond to health-related water quality violations, which could provide them with a new tool for monitoring public health concerns, according to new research. In a new study, researchers saw increased purchases of bottled water and over-the-counter antidiarrheal medicine in areas where health-related violations of the Safe Water Drinking Act were reported.
