Multifunctional roles of water in the ozonolysis of limonene aerosols

Written by

Limonene, a monoterpene found in citrus peel oils and many household products, readily undergoes ozonolysis to form secondary organic aerosols. Researchers investigate the role of water in the process and the environmental implications.

Aerosols are suspensions of tiny solid particles or liquid droplets, which significantly impact Earth’s atmosphere by influencing the planet’s energy balance, global climate, and public health. Secondary organic aerosols can be formed due to various physicochemical processes involving natural and human-made aerosols, or their gas-phase precursors. Limonene, a type of monoterpene, often found in citrus peel oils and many household and […]

Air pollution monitoring and its role in public health

Written by

Air pollution monitoring is an important factor in air quality management. Both established long-term monitoring stations and short-term seasonal atmospheric field measurements are required to understand how atmospheric chemistry changes in response to air pollution regulation. Professor Schwab and his team from the University at Albany maintain long-term rural monitoring stations as well as highly specific mobile air pollution measurements […]

Digital holography: Unlocking the mysteries of aerosols

Written by

Aerosols are diverse and complex particles in our atmosphere. Varying hugely in both size and shape, scientists have faced significant technical challenges in measuring how these particles scatter and absorb the sun’s light, making it difficult to accurately assess their influence on the Earth’s atmosphere. Dr Matthew J. Berg at Kansas State University and his colleagues are now combatting the issue through the cutting-edge […]
