New Research Shows Crude Oil Chemicals Move and Change More Quickly than EPA Standards
March 7, 2017 01:29 PM - Louisiana State University

The Environmental Protection Agency, or EPA, lists about 65 chemicals as “toxic pollutants” under the Clean Water Act, 16 of which are polycyclic aromatic hydrocarbons, or PAHs. LSU Department of Environmental Sciences doctoral candidate Parichehr Saranjampour conducted research on a chemical class of PAHs that is not on the EPA’s list — Dibenzothiophene, or DBT. DBT and its three related chemical compounds contain sulfur that is found in crude oil. Saranjampour studied how these chemical compounds move and change over time, which revealed new information that has never been published before. Her findings differ from the EPA’s information about these chemical compounds. This new research was published today in the Journal of Environmental Toxicology and Chemistry.

Chemical pollution in China: which metal poses the greatest risk to the Bohai region's freshwater ecosystem?

Professor Andrew Johnson and Dr Monika Jürgens, Environmental Scientists at the Centre for Ecology & Hydrology, contributed to a recent study looking at which metal presents the greatest risk to the freshwater ecosystem in the Bohai region of China. They explain more:

Thanks to support from the Natural Environment Research Council Newton Fund, the Centre for Ecology & Hydrology (CEH) has been collaborating with the Research Center for Eco-Environmental Sciences, in Beijing, China since the beginning of 2016 on the topic of chemical pollution in China. 

USGS Finds Elevated Levels of Arsenic, Radon, Methane in Some Private Wells in Lycoming County, Pennsylvania
March 7, 2017 08:32 AM - United States Geological Survey (USGS)

Tests of 75 private drinking water wells in Lycoming County, in north-central Pennsylvania, found water from most of the sampled wells contained concentrations of radon that exceeded a proposed, nonbinding health standard for drinking water. Smaller percentages of the wells contained concentrations of arsenic or methane that exceed existing drinking water standards.

United Kingdom CO2 Emissions Fall to Lowest Level in Nearly a Century
March 6, 2017 02:12 PM - Yale Environment 360

A record drop in coal use — coupled with the rapid growth of renewable energy, an expansion of energy efficiency programs, and an increase in burning natural gas for electricity — have driven carbon dioxide emissions in the UK to their lowest levels since the 1920s, according to a new study by the non-profit group, Carbon Brief.

Brake Dust May Cause More Problems Than Blackened Wheel Covers
March 3, 2017 10:23 AM - Georgia Institute of Technology

Though tailpipe emissions could fall in the years ahead as more zero-emission vehicles hit the streets, one major source of highway air pollution shows no signs of abating: brake and tire dust.

Metals from brakes and other automotive systems are emitted into the air as fine particles, lingering over busy roadways. Now, researchers at Georgia Institute of Technology have shown how that cloud of tiny metal particles could wreak havoc on respiratory health.
