The particulate air pollution is a growing
problem in cities with emissions generating activities. Size and chemical
composition of ambient particulates strongly influence on human health,
visibility and ecosystem etc.
This study looked into the origin of the
particles in the atmosphere, and divided particles into groups based on
morphology and elemental composition. These particles morphology and chemical
composition, illustrate an abundance of natural elements within the zone. It is
suggested, though, some of the elements presented are directly related with
human activities, and are of much interest from the public health and
environmental perspectives.
