More About This Title Aerosol Science - Technology and Applications
English
Aerosols influence many areas of our daily life. They are at the core of
environmental problems such as global warming, photochemical smog and
poor air quality. They can also have diverse effects on human health, where
exposure occurs in both outdoor and indoor environments.
However, aerosols can have beneficial effects too; the delivery of drugs to the
lungs, the delivery of fuels for combustion and the production of nanomaterials
all rely on aerosols. Advances in particle measurement technologies have
made it possible to take advantage of rapid changes in both particle size and
concentration. Likewise, aerosols can now be produced in a controlled fashion.
Reviewing many technological applications together with the current scientific
status of aerosol modelling and measurements, this book includes:
• Satellite aerosol remote sensing
• The effects of aerosols on climate change
• Air pollution and health
• Pharmaceutical aerosols and pulmonary drug delivery
• Bioaerosols and hospital infections
• Particle emissions from vehicles
• The safety of emerging nanomaterials
• Radioactive aerosols: tracers of atmospheric processes
With the importance of this topic brought to the public’s attention after the
eruption of the Icelandic volcano Eyjafjallajökull, this book provides a timely,
concise and accessible overview of the many facets of aerosol science.
