This chapter discusses the structure and composition of the Earth's atmosphere. The Earth's atmosphere is a reservoir of several gases. The gas molecules in this reservoir are continuously exchanged because of the interaction of different sources and sinks. The average time spent in the atmosphere...
For many people, the state of the atmosphere is a key measure of the health of the environment. Climate affects Australia's animals and plants as well as the economic, social and medical wellbeing of our society. The composition of the atmosphere dictates air quality, which affects human heal...
Environmental Impact Assessment (EIA) was rigorously followed during setting of new industries and environmental modelling has been used to carry out future foresting of pollution and resorting to effective control measures of pollution. Basically, our environment is composed of atmosphere, earth, water...

Measurement and modeling of vertically resolved aerosol optical properties and radiative fluxes over the ARM SGP Site during the May 2003, 2004 In order to meet one of its goals - to relate observations of radiative fluxes and radiances to the atmospheric composition - the Department of Energy's...
or from the imperfect reconcilement in the writer's own mind of the struggling elements of thought which are now first brought together by him; or, perhaps, from the composition of the work at different times—are questions, like the similar question about the Iliad and the Odyssey, which ...
Neither is the soul variable and diverse; for that which is immortal must be of the fairest and simplest composition. If we would conceive her truly, and so behold justice and injustice in their own nature, she must be viewed by the light of reason pure as at birth, or as she is ...

and proofs of provenance and origin. This would be for a product where essentially it is impossible to distinguish with certainty the origin of the product based upon its chemical composition (impurities). It is quite possible to change the impurities in the product with post-production processing...
