New research from a team led by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) zeroes in on carpets as an especially potent – and difficult to clean – reservoir of tobacco contaminants.
Safe drinking water is threatened globally by the increased toxicity of phytoplankton — or microscopic algae — blooms. The need for a better understanding of when and where the blooms will emerge spurred Virginia Tech researchers to start developing the first automated, real-time lake phytoplankton forecasting system. Working with the University of Florida, Virginia Tech faculty have been awarded a $2.

The latest headlines from the Food and Water Safety channel on Newswise.
China's rapid industrialization and economic growth have led to an increasing demand for energy, with coal being the primary source of power generation. As a result, China boasts the world's largest fleet of coal-fired power plants (CFPPs), contributing over 60% of its domestic electricity supply. However, the operation of these CFPPs has also resulted in significant air pollutant emissions, leading to adverse impacts on public health and the environment.
Researchers from Michigan State University’s top-ranked School of Packaging have developed a way to make a promising, sustainable alternative to petroleum-based plastics more biodegradable. A team led by Rafael Auras has made a bio-based polymer blend that’s compostable in both home and industrial settings. The work is published in the journal ACS Sustainable Chemistry & Engineering.

Today's catalysts for removing unburnt methane from natural-gas engine emissions are either inefficient at low, start-up temperatures or break down at higher operating temperatures. A new single-atom catalyst solves both these problems and removes 90% of the methane.
Hazy, hazardous conditions from climate change-driven Canadian wildfires have prompted researchers to examine the physicochemical and toxicological properties.
Fertilizer restrictions along Florida’s 156-mile-long Indian River Lagoon were intended to reduce nutrient inputs from urban and agricultural land uses. The hope was that water quality would improve by reducing the nitrogen load. While these restrictions were well-intended, a study finds fertilizer use is not the root cause of the lagoon’s environmental issues. It’s sewage. For decades, fertilizer use was implicated for about 71 percent of the lagoon’s environmental impairments. In fact, current estimates show 79 percent of nitrogen loading is from septic systems; 21 percent is from residential fertilizer use.
Approximately a third of all anthropogenic methane is emitted by ruminant livestock. These animals get nutrients through fermenting food in four-chambered stomachs found in cows, sheep, and goats.
