Growing sustainable energy crops without increasing greenhouse gas emissions, may be possible on seasonally wet, environmentally sensitive landscapes, according to researchers who conducted a study on Conservation Reserve Program (CRP) land.

Debasish Saha, postdoctoral scholar in plant sciences, Penn State College of Agricultural Sciences, and colleagues measured the amount of nitrous oxide, a potent greenhouse gas, emanating from plots of biofuels-producing switchgrass — a native perennial grass — and miscanthus — a non-native grass species — growing in an experimental area in eastern central Pennsylvania and compared it to emissions from adjacent, undisturbed CRP acres. The experiment took place in a long-term monitoring site managed by the U.S. Department of Agriculture's Agricultural Research Service.

Babies in prams accompanying older siblings on the school run are twice as likely to be exposed to harmful air pollution in the morning than in the afternoon, a new study has found.

Iran can transition to a fully renewable electricity system and financially benefit from it by 2030. Researchers at Lappeenranta University of Technology (LUT) show that major oil-producing countries in the Middle East and North Africa (MENA) region could turn their abundant renewable energy resources into lucrative business opportunities in less than two decades.

Scientists at the Argonne National Laboratory in Illinois have created a new sponge-like material that can repeatedly soak up oil spills. The material, which can absorb up to 90 times its own weight in oil, could make it faster and easier to clean up offshore oil spills, the scientists said.

The United States has managed to reduce the amount of air pollution it produces, but you wouldn’t know it from looking at and breathing in the air. That’s because pollution created in Asia is gradually making its way across the Pacific Ocean to the western hemisphere.

According to research published in the Atmospheric Chemistry and Physics journal, up to 65 percent of the newly created smog in the U.S. has actually drifted over from Asia. The country’s western states are most vulnerable to the increase in ozone due to their proximity to the continent.

A good rain can have a cleansing effect on the land. But an MIT study published today in Nature Communications reports that, under just the right conditions, rain can also be a means of spreading bacteria.

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.

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. 

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.

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.
