The Earth’s atmosphere contains substances called greenhouse gases (GHGs), which store and reflect heat to contribute to the greenhouse effect. “Greenhouse gases” are a broad category of chemical substances present in Earth’s atmosphere. This natural phenomenon is essential for maintaining Earth’s temperature at a level favorable to life.
The most common greenhouse gas is carbon dioxide (CO2), mostly emitted by human activity like burning fossil fuels and deforestation. A powerful greenhouse gas released during the digesting of animals, the growing of rice, and the extraction of fossil fuels is methane (CH4). Another important greenhouse gas emitted by industrial and agricultural processes is nitrous oxide (N2O).
When considering the possibility to cause global warming, nitrous oxide (N2O) is known as a considerably stronger greenhouse gas than carbon dioxide (CO2). The greenhouse gas potential (GWP) measures the amount of heat a greenhouse gas retains in the atmosphere over a certain amount of time about carbon dioxide. According to estimates, nitrous oxide has a global warming potential (GWP) that is around 298 times more than that of CO2 over 100 years. This indicates that nitrous oxide contributes much more to the greenhouse effect and climate change than carbon dioxide.
The production of nitrous oxide from agricultural operations is one of the main causes of emissions. The main cause of these emissions is the usage of fertilisers based on nitrogen, which can go through processes that produce nitrous oxide. Nitrous oxide emissions are also a result of several industrial operations, such as burning fossil fuels and some waste treatment procedures.
Despite its immense strength, it’s crucial to remember that nitrous oxide has a significantly lower atmospheric concentration than carbon dioxide. CO2 is the most common greenhouse gas released by humans, mostly from the use of fossil fuels for energy and deforestation. Because of its enormous concentration, CO2 is the principal cause of long-term climate change.
From Where Does Nitrous Oxide Originate?
Several natural and human-related activities produce nitrous oxide (N2O). Using fertilizers based on nitrogen in agriculture is one of the main sources of nitrous oxide. Through nitrification and denitrification, soil bacteria may transform nitrogen molecules into nitrous oxide when farmers apply fertilizers to their fields.
Another responsible for nitrous oxide emissions is livestock, particularly ruminant animals like cows. These animals’ digestive tracts produce nitrogen molecules through microbial activity, which may eventually culminate in nitrous oxide production. Emissions of nitrous oxide may also originate from wastewater treatment facilities. Nitrous oxide is a result of microbial activity in these facilities that breaks down organic materials.
Nitrous oxide is also released into the atmosphere by some industrial operations, such as the nitric acid manufacturing process and the burning of fossil fuels. Nitrous oxide is a byproduct of the chemical events that occur during the formation of nitric acid.
Soils and seas are two natural sources of nitrous oxide. Microbial activity in marine habitats produces oceanic emissions. Microbial activity in soils can create nitrous oxide, especially in environments with low oxygen levels, such as wet or compacted soils.
Is Nitrous Oxide more harmful than CO2?
Carbon dioxide emissions constitute a large, unsolvable, and rapidly approaching problem in terms of global climate calamity. It’s not the only issue, though. Scientists are racing to comprehend the consequences of other pollutants’ fast warming of the planet before it’s too late. Nitrous oxide is one pollution about which specialists have been warning for years, but there hasn’t been much worldwide action because it is closely related to food.
Not only can nitrous oxide weaken the ozone layer, but also it is 300 times more powerful than carbon dioxide. Its shorter lifespan suggests that cutting it might have a bigger, quicker effect on global warming.
However, agriculture especially fertilised soil and animal waste is the main source of nitrous oxide, making it more difficult to control. But NO2, a secondary pollutant from combustion processes, especially in cars and industrial settings, is produced. As a primary cause of smog, it has a more direct effect on human health and air quality. In addition to causing respiratory disorders, NO2 may worsen pre-existing medical issues and irritate the respiratory system.
