Environmentally Persistent Free Radicals in Wildfire Charcoals Remain Stable for Years

Reactive oxygen species (ROS) cause oxidative stress at the cellular level. Research shows that this way, amongst others, they inhibit the germination capacity of plants, produce cytotoxins or exert toxic effects on aquatic invertebrates.

EPA Underestimates Methane Emissions from Oil and Gas Production, Research Shows

The Environmental Protection Agency (EPA) is underestimating methane emissions from oil and gas production in its annual Inventory of U.S. Greenhouse Gas Emissions and Sinks, according to new research from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS).

Bivalve Sensors add ‘Mussel’ to Environmental Monitoring Systems

The opening and closing of mussels in unison could give researchers an efficient way to detect the presence of toxins in aquatic environments.

Eroded Seabed Rocks Provide Key Source of Nutrition for Marine Organisms

According to a new study, drifting sea organisms at the bottom of the food chain are receiving an essential source of nutrition from eroded seabed rocks.

New Study Helps Differentiate Local from Global Sources of Plutonium Pollution in Soil

Scientists analyzed extremely low levels of plutonium pollution present in the soils and made a discovery that could power future “clean up” operations on land near nuclear power plants, which would be time- and cost-efficient.

New First-Time Study to Examine the Impact of Ocean Noise Pollution on Ireland’s Marine Life

Ireland’s first real-time acoustic monitoring project of cetacean species (whales, dolphins and porpoise) was launched this week off the South Coast of Ireland, with the goal of creating a near real-time detection model for these species and examining the impact rising ocean noise pollution is having on Ireland’s marine life.

Study Uncovers How Bushfire Smoke Traveled Around the World

It's not just how hot the fires burn - it's also where they burn that matters. During the recent extreme fire season in Australia, which began in 2019 and burned into 2020, millions of tons of smoke particles were released into the atmosphere.

Nanoplastics in Estuarine Waters can Clump and Form Larger Clusters

As plastic debris weathers in aquatic environments, it can shed tiny nanoplastics. Although scientists have a good understanding of how these particles form, they still don't have a good grasp of where all the fragments end up. Now, researchers reporting in ACS' Environmental Science & Technology have shown experimentally that most nanoplastics in estuarine waters can clump, forming larger clusters that either settle or stick to solid objects, instead of floating on into the ocean.
