Air Pollution in NCR
Abstract
Since the past two decades, air pollution has become a global public health issue and identified as a major
environmental health hazard. Due to rapid development, society is facing serious challenges such as:
climate change, global warming, ozone hole, acid rain and smog. Increasing energy demand and growing
per capita energy consumption has led to such serious challenges. Their notoriety is evidence for the
growing concern about the human impacts on climate. Recently, the onset of winter in every year Delhi
and National capital Region (NCR) of India witnessed hazy and dusty condition or smog, which prolonged
for many days (October to November). In present investigation, on the basis of air quality monitored by
various Government organizations for the years 2009 – 2015, the occurrence of smog in Delhi is studied
and fog is categorized as mixture of Classical and Photochemical Smog. In present investigation the overall
scientific aspects driving the research are as: important processes controlling levels of smog and surface
exchange, impacts of smog on human health and the environment and important processes controlling
the interaction between climate and air pollution.
