Acidification of slurry to reduce ammonia and methane emissions

Ammonia released into the environment is a major problem. Agriculture is considered the most prolific polluter—it is responsible for 95 percent of these emissions in Germany. The colorless, acrid gas is toxic in higher ...

Microbe-based faux beef could save forests, slash CO2 emissions

Gradually replacing 20 percent of global beef and lamb consumption with meat-textured proteins grown in stainless steel vats could cut agriculture-related CO2 emissions and deforestation in half by 2050, researchers reported ...

Unexpected wildfire emission impacts air quality worldwide

In lab studies of wildfire, nitrous acid seems like a minor actor, often underrepresented in atmospheric models. But in the real-world atmosphere, during wildfires, the chemical plays a leading role—spiking to levels significantly ...

Scientists measure HONO and NOX flux in farmland

Researchers at the Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science, developed an automated dynamic chamber system to simultaneously measure the HONO flux and NOX flux in farmland ecosystems. ...

Where does bad air come from?

Auchencorth Moss is one of Scotland's distinctive moorlands, which for generations have provided people with a lifesaving source of peat to burn to keep warm.

Research links soil mineral surfaces to key atmospheric processes

Research by Indiana University scientists finds that soil may be a significant and underappreciated source of nitrous acid, a chemical that plays a pivotal role in atmospheric processes such as the formation of smog and determining ...

Chemists identify role of soil in pollution control

Scientists have long known that air pollution caused by cars and trucks, solvent use and even plants, is reduced when broken down by naturally occurring compounds that act like detergents of the atmosphere. What has not been ...

Clean air: Fewer sources for self-cleaning

Up to now, HONO, also known as nitrous acid, was considered one of the most important sources of hydroxyl radicals (OH), which are regarded as the detergent of the atmosphere, allowing the air to clean itself. A research ...
