Ambient air pollution has gained recognition as an important source of cardiovascular morbidity and mortality (Brook et al. 2004; Dockery et al. 1993; Pope et al. 1995).
Its remoteness and lack of light pollution led to its recognition as Britain's first dark sky park.
But Dr. Joshua S. Apte, an assistant professor of environmental engineering at the University of Texas at Austin, who has studied Delhi's air pollution since 2007, said recognition was a start.
When water pollution incidents occur, the recognition of pollution sources (including source location and amount of pollutant) is a primary task in emergency response, which has attracted the attention of many researchers and governors.
The recognition of pollution sources with the aid of an optimization algorithm combined with mathematical analysis methods is simple, practical and has been widely applied (Cao et al. 2010; Yin et al. 2011).
Since the images from the previous stage could not provide information about more than three elements in recognition of pollution hot-spots, the anomalies of elements (distribution of a combination of elements in each area) were determined using the zoning map of elements obtained from FCC, map overlay, and identification of heavy metal hot-spots.
Action came after a belated recognition of the pollution caused by shipping, with sulphur emissions held responsible for thousands of premature deaths each year.
As for India, Professor Apte said he believed public opinion had shifted, and that there was a much broader recognition of air pollution as a problem.
It also demonstrates the recognition of plastic pollution as a contaminant of concern in the United States, which is a critical step for future prevention and cleanup.
Recognizing that the global economy links us all together, thereby making us all responsible to some extent for each other's pollution, and then acting on that recognition -- that is truly remarkable.
