Study finds unexpected levels of bromine in power plant exhaust

Some coal-fired power plants in the United States emit gases that may produce harmful compounds in drinking water and can have significant effects on the atmosphere, according to new research. A new study published in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union, finds unexpectedly high levels of reactive bromine-containing chemicals in plumes emitted by coal-fired power plants not using a particular type of exhaust-cleaning technology.

Policy changes in Mongolian capital could improve health, decreasing lives lost to air pollution

Exposure to dangerous contaminants in Ulaanbaatar, Mongolia could increase by 10 percent or more by 2024, exacerbating health problems in one of the most polluted cities in the world, a new study finds.

Residents of Ulaanbaatar, the most populous city in Mongolia, rely heavily on coal to survive frigid winters in a valley where air pollution is easily trapped. Air pollution in Ulaanbaatar caused an estimated 1,250 premature deaths in 2014, according to Drew Hill, a graduate student in environmental health at the University of California, Berkeley. Hill was part of a research team that presented an air pollution and health report to the Mongolian Ministry of the Environment and Green Development in the summer of 2014.
