What is Nitrogen Dioxide NO2?
Nitrogen Dioxide (NO2), accounts for more than 70% of the air present in the environment. And it is the most abundant gas present. For instance, Traffic on the road and the burning of fossil fuels result in poisonous NO2 air pollution. Hence, it is harmful to humans, plants, and animals.
Sources Of Nitrogen Dioxide (NO2) Gas
NO2 is present in the environment in a very small quantity. But due to our excessive use of resources and other activities, nitrogen dioxide level is increasing to a troublesome level. There are both natural and men-made causes of the formation of the no2 gas.
Natural causes include:
Volcano eruption or
active volcanic sites.
Biological decay of
waste for fertilizer
Lightning strikes-
facilitates the formation
of the NO2 gas.
Oceans
Manmade means of production of Nitrogen Dioxide (NO2) gas are:
Car, truck, boots,
and airplane emissions
Power
plants
Ammonia-emitting fertilizers
Diesel-powered
heavy machines
Kerosene and
gas stoves
The main source of nitrogen dioxide produced by human activity is the combustion of fossil fuels. Such as the fuel used in automobiles, the creation of nitric acid, welding, explosives, refinement of petrol and metals, and commercial and food processing.
Health & Environmental Impacts of NO2 Gas
NO2 is part of the NOx group of highly reactive gases. Whereas NO2 is a brownish acidic gas with and pungent odor. It reacts with O2 to form nitric acid responsible for corrosion. And it also plays role in the formation of other pollutants like smog, PM, and acid rain. It is a flame accelerator but itself not combustible.
Health Impacts Due to Nitrogen Dioxide (NO2)
Altered lungs
function
Breathing
problem
Asthma
Reduced
immunity
Irritation in
airways
Coughing, breathing
difficulty, wheezing
Heart
failure
Reduced birth
weight, high risk
of premature death
Environmental effects are severe due to
excessive concentration of this gas:
Hazy air (smog)
Polluting water
Generates ground
level O3
Increases
PM levels
Acid rain- forming
an acidic compound
with moisture present
in the air
Affects the vegetation,
growth of plants
NOx + other
chemicals leads
to formation of PM.
Acts as a stressor to
plants and results
in chlorophyll content
reduction.
Corrective Measures To Reduce Nitrogen Dioxide (NO2) Gas
The primary preventive measure is to monitor the concentration of NO2 which our Prana air sensor and Air quality monitors are quite useful. Other than that there are some corrective measures that could help us keep safe from the respiratory repercussion of this gas:
Vehicles with low emission rates can help us with the reduced production of NO2
Alternate fuels including hydrogen cells and electric-powered cars can be useful in bringing down the overall footprint of NO2 production.
Avoid traffic congestion. Improving engines to be more efficient
Using public transport
Use of a closed environment for the production of fertilizer and processing of the gases produced in it.
