Fossil fuel burning and industrial operations are the main sources of sulfur oxide emissions into the environment. Sulfur oxides are mostly composed of sulfur dioxide (SO₃) and sulfur trioxide (SO₃). These oxides are important for the chemistry of the atmosphere and the environment.The main form of sulfur oxide released into the atmosphere is sulfur dioxide (SO₂). It is created by burning fossil fuels that include sulfur, like coal and oil, as well as by industrial operations like refining and smelting metal. Although there are some natural sources of SO₂ emissions, such as volcanic eruptions, human sources predominate, particularly in urban and industrialized regions. Colorless and odorous, SO₂ poses a serious threat to human health and the environment when it is present in the atmosphere.Sulfate aerosols and sulfuric acid (H₂SO₄) can be produced in the atmosphere via chemical interactions between sulfur dioxide and sulfur. Acid rain is a result of these substances, and it can harm lakes, forests, and aquatic ecosystems. In addition to harming the environment, acid deposition corrodes infrastructure and buildings, resulting in financial expenses.In terms of health, breathing in sulfur dioxide aggravates respiratory ailments including bronchitis and asthma. Extended exposure can worsen lung function and cause respiratory disorders, especially in susceptible groups like the elderly and children.Although it is not as frequently released into the atmosphere as sulfur dioxide (SO₂), sulfur trioxide (SO₃) plays a vital role in the creation of secondary aerosols. Sulfuric acid is created when it quickly combines with water vapor and other atmospheric substances, which furthers acid deposition and the production of fine particulate matter (PM₂.₅). These tiny particles have the ability to enter the lungs deeply, which can cause respiratory and cardiovascular issues.Technological advancements like flue gas desulfurization (FGD) systems, which extract sulfur dioxide from industrial emissions before releasing it into the environment, are one way to lessen the impact of sulfur oxides. Reducing sulfur oxide emissions from the transportation and industrial sectors is another goal of legislation like emission limits, as well as the use of cleaner fuels and lower sulfur energy sources.To mitigate environmental deterioration, improve air quality, and safeguard human health, it is imperative to comprehend and manage sulfur oxides. In order to effectively address this major environmental concern, policies and technology pertaining to emission sources, atmospheric processes, and the interaction of sulfur oxides with ecosystems will be informed by ongoing study.
