"Episodes of air pollution throughout the 20th and 21st centuries have had a huge influence socially, economically and politically. From the Great Smog of London to the Kuwait Oil Fires, and from the ashes of Mount St Helens to air pollution in Beijing, this book chronicles their enduring legacies in medicine, science and public policy. Using technical information and insight from witnesses directly involved in the incidents, ten key episodes are brought together to allow comparison and analysis. Written for students, academics and professionals of atmospheric physics and chemistry, environmental science, public policy and other clinical disciplines, Air Pollution Episodes provides the unique opportunity to understand and learn from the most famous and sometimes devastating incidences of air pollution globally."--Publisher's website

First published in 1987, Peter Brimblecombe's book provides an engaging historical account of air pollution in London, offering a fascinating insight into the development of air pollution controls against a changing social and economic background. He examines domestic and industrial pollution and their effects on fashions, furnishings, buildings and human health. The book ends with an intriguing analysis of the dangers arising from contemporary pollutants and a glimpse of what the future may hold for London.

June 2019 saw large-scale street protests in Hong Kong that impeded traffic flow along streets in areas around to the Legislative Council building. These had the potential to reduce overall air pollutant emissions from traffic and lower their concentrations. Two roadside monitoring stations relatively close to the Legislative Council reveal that measured concentrations of nitrogen dioxide declined during the protests compared with measurements from other sites by at least 50% on many occasions. There were only subtle changes in particulate loads and no evidence of any reduction in carbon monoxide concentrations. Pedestrianisation and bus route rationalisation are often seen as methods to reduce exposure in congested areas, but the observations here suggest that the substantial improvements in the nitrogen dioxide levels might not be matched by improvements in other pollutants. Plans for changes to street layouts to improve air quality need careful investigation before they are implemented.

Written by natural scientists and historians, The Silent Countdown explores relations between societies and their natural environment from the Middle Ages to the present. Global views of ecological history in the long term are provided as well as sophisticated models quantifying the flow of energy across regional ecosystems. The impact of processes of production and consumption upon the natural habit (clearing of forests, soil erosion), of high pollution densities in urban centers (smoke, stench, water pollution) are demonstrated: it is shown, how people reacted to it and how efficient the measures were to control it. Battles between the owners of iron works and chemical industries, the local councils, the experts and the suffering peole suggest a surprisingly early concern of a loss of natural environment in the face of industrialization
