Cleaning up ocean pollution is no simple task, as an effort to fish plastic out of the Pacific Ocean is revealing.
In September, scientists launched a 600-meter-long boom meant to herd plastic debris from the great Pacific garbage patch into a net (SN Online: 9/7/18). The trash accumulation, which is twice the size of Texas, swirls in waters between California and Hawaii.
Satellites may be a more accurate way to track smog-producing ammonia.
It’s notoriously tricky to pinpoint accurate numbers for ammonia gas emissions from sources such as animal feedlots and fertilizer plants. But new maps, generated from infrared radiation measurements gathered by satellites, reveal global ammonia hot spots in greater detail than before. The new data suggest that...
Off a gravel road at the edge of a college campus — next door to the town’s holding pen for stray dogs — is a busy test site for the newest technologies in drinking water treatment.
In the large shed-turned-laboratory, University of Massachusetts Amherst engineer David Reckhow has started a movement. More people want to use his lab to test new water treatment technologies than the...
There’s a big problem where the rubber meets the road: microplastics.
Scientists analyzed more than 500 small particles pulled from the air around three busy German highways, and found that the vast majority — 89 percent — came from vehicle tires, brake systems and roads themselves. All together, these particles are classified by the researchers as microplastics, though they include...

For sale: Pristine lake. Price negotiable.
Most U.S. government attempts to quantify the costs and benefits of protecting the country’s bodies of water are likely undervaluing healthy lakes and rivers, researchers argue in a new study. That’s because some clean water benefits get left out of the analyses, sometimes because these benefits are difficult to pin numbers on. As a result, the...
