Mar. 14, 2023 A research team demonstrates that increased levels of ozone resulting from anthropogenic air pollution can degrade insect sex pheromones, which are crucial mating signals, and thus prevent successful ...
Mar. 10, 2023 New evidence shows that exceeding the World Health Organization (WHO) ozone limit is associated with substantial increases in hospital admissions for heart attack, heart failure and stroke. Even ...
Mar. 8, 2023 A new study finds that smoke particles in the stratosphere can trigger chemical reactions that erode the ozone layer -- and that smoke particles from Australian wildfires widened the ozone hole by 10 ...
Feb. 14, 2023 Researchers have summarized the threats that future rocket launches would pose to Earth's protective ozone ...
Jan. 18, 2023 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 ...
Dec. 9, 2022 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 ...
Dec. 7, 2022 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 ...
Dec. 6, 2022 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 ...
Nov. 14, 2022 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 ...
Nov. 9, 2022 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 ...
Oct. 27, 2022 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 ...
Sep. 29, 2022 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 ...
Sep. 22, 2022 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 ...
Sep. 15, 2022 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 ...
Sep. 6, 2022 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 ...
Sep. 1, 2022 High levels of hydroxyl radicals (OH) can be generated indoors, simply due to the presence of people and ...
Aug. 24, 2022 Researchers have developed a new method for assessing the impacts of ozone-destroying substances that threaten the recovery of the ozone ...
July 28, 2022 New evidence from Antarctica shows that toxic 'fluorinated forever chemicals' have increased markedly in the remote environment in recent decades and scientists believe CFC-replacements ...
July 7, 2022 Researchers have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than ...
July 7, 2022 Researchers have discovered why reducing particle pollution is leading to a rise in photochemical smog in some emerging economies such as India, Africa and ...
