Air Pollution - Sources and Classification

Anthropogenic air pollution sources

What one experiences today as atmosphere is a transient snapshot and result of its evolutionary history. Much of the development and present status was explained based both on scientific knowledge, and combined with established facts, even speculation. The planet Earth was formed around 4600 million years ago by the gravitational accretion of relatively small rocks and dust, within the solar ne...

Quantification of Air Pollution Sources

RESUMO – Quantificação de Poluição do Ar – A atividade industrial é uma das principais causas da poluição do ar urbano. Várias técnicas são utilizadas para monitorar e analisar os agentes poluidores. A técnica de modelamento de receptor é uma delas. A aplicação de programação linear para a quantificação de fontes poluidoras do ar, utilizando o modelamento de receptor, é apresentada neste artigo...

Residential and Local Sources of Air Pollution

Since the early 1970s, environmental agencies have focussed most of their attention on large point sources and transport sources of air pollutants. The myriad of small sources scattered throughout suburban Australia, such as people’s heating appliances, lawnmowers and suburban restaurants, have received little attention. Perhaps this is simply because they are so dispersed or they may have been...

Local Arctic air pollution: Sources and impacts

Local emissions of Arctic air pollutants and their impacts on climate, ecosystems and health are poorly understood. Future increases due to Arctic warming or economic drivers may put additional pressures on the fragile Arctic environment already affected by mid-latitude air pollution. Aircraft data were collected, for the first time, downwind of shipping and petroleum extraction facilities in t...
