Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years; researchers believe chlorofluorocarbons (CFCs) aren't the only things to ...
The Hunga Tonga-Hunga Ha'apai volcano changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to unprecedented losses in the ozone layer of up to 7% over large areas of the Southern Hemisphere. ...
Researchers have studied the effects of elevated O3 on five C3 crops (chickpea, rice, snap bean, soybean, wheat) and four C4 crops (sorghum, maize, Miscanthus × giganteus, switchgrass). Their ...
Using tools hitched to the nose cone of their research planes and sampling more than 11 miles above the planet's surface, researchers have discovered significant amounts of metals in aerosols in the ...

Researchers have summarized the threats that future rocket launches would pose to Earth's protective ozone ...

Long-term measurements in the urban area of Innsbruck, Austria, show that the fraction of ozone near the surface tends to be overestimated in atmospheric models. Consequently, a fundamental ...

Assuring that a growing global population has access to clean water will require new water treatment methods. One of these next-generation methods involves a form of iron called ferrate, which ...

When winter chill strikes, people stay indoors more often, giving airborne pathogens -- such as SARS-CoV-2 and influenza -- prime opportunities to spread. Germicidal ultraviolet (GUV) lamps can help ...

Researchers have simulated how climate change will affect the distribution of two leading allergens -- oak and ragweed pollens -- across the contiguous United States. The results may make your eyes ...

A new experiment conducted at the world's largest particle physics laboratory, demonstrates the mechanism for how the gas-phase form of iodine -- known as iodic acid -- forms, and suggests it ...

When fields of oilseed rape are exposed to diesel exhaust and/or ozone -- both found in emissions from diesel burning vehicles and industry -- the number of parasitic insects available to control ...

The annual Antarctic ozone hole reached an average area of 8.9 million square miles (23.2 million square kilometers) between Sept. 7 and Oct. 13, 2022. This depleted area of the ozone layer over the ...

Over the past decades, rising levels of ozone pollution have been interrupting pollination, impacting the livelihood of both plants and the animals that pollinate them. Researchers now explain how an ...

At the beginning of the year, the World Health Organization (WHO) announced that the Middle East ranks among the regions with the worst air quality. There is a common misconception that desert dust ...

Dirty windows can harbor potentially harmful pollutants under protective films of fatty acids from cooking emissions -- and these can hang around over long periods of ...

The 2019/20 wildfires in Australia transported more smoke into the atmosphere than observed ever before anywhere in the world. In the so-called Black Summer, three times as many particles reached ...

High levels of hydroxyl radicals (OH) can be generated indoors, simply due to the presence of people and ...

Researchers have developed a new method for assessing the impacts of ozone-destroying substances that threaten the recovery of the ozone ...
