This document discusses smog and air pollution in Delhi, India. It provides background on smog, noting that it is a mixture of smoke and fog composed of pollutants from coal emissions, vehicular emissions, industrial emissions, and more. It then outlines some health effects of smog like irritation of the eyes and respiratory system, worsening of asthma symptoms, and lung damage. Charts and data show the main sources of particulate matter pollution in Delhi and dangerously high levels of various pollutants beyond permissible limits. The document concludes with information on air quality indices and images related to the smog conditions in Delhi.

CHAMBER

2.  Smogis a form of Air Pollution. It is a mixture of smoke and fog and
refers to smoky fog, its opacity, and odour. This kind of visible air pollution
is composed of nitrogen oxides, sulphur oxides, ozone, smoke or
particulates among others (less visible pollutants include carbon monoxide,
CFCs and radioactive sources).
 Human-made smog is derived from coal emissions, vehicular emissions,
industrial emissions, forest and agricultural fires and photochemical
reactions of these emissions.

3.  Harmful for eyes.
 Coughing and throat or
chest irritation:High levels of ozone
can irritate your respiratory system, generally lasting
for a few hours after you’ve been exposed to smog.
However, ozone can continue to harm your lungs even
after symptoms disappear.
 Worsening of asthma
symptoms: If you suffer from asthma,
exposure to high levels of ozone from smog can trigger
asthma attacks.
 Difficulty breathing and
lung damage: Smog can make it feel
difficult to inhale deeply, especially during a workout
due to reduced lung function, according to the Mayo
Clinic.

4. The national capital shares it’s borders with farming
states like Haryana and Uttar Pradesh, therefore, one
of the main reasons why Delhi is experiencing such
high pollution levels is due to CROP BURNING,
lit garbage and road dust.
Secondly, despite the ban, there were many areas
in Delhi-NCR where people burst firecrackers,
which has added to the smog build-up.
The vehicular pollution caused by cars, trucks,
buses and industrial pollution combined adds up
and creates unsuitable living conditions.

8.  An air quality index (AQI) is a number used by government agencies to
communicate to the public how polluted the air currently is or how polluted it is
forecast to become. As the AQI increases, an increasingly large percentage of
the population is likely to experience increasingly severe adverse health effects.
 Air Quality Index measures five major pollutants for which it has established
National Ambient Air Quality Standards under the Clean Air Act. The
pollutants are sulphur dioxide, carbon monoxide, nitrogen dioxide
and ozone.AQI VALUES HEALTH CONCERN COLORS
0-50) GOOD GREEN
(51-100) MODERATE YELLOW
