- The largest source of SO2 in the atmosphere is the burning of fossil fuels by power plants and other industrial facilities. Hence, statement 1 is correct.
- Smaller sources of SO2 emissions include: industrial processes such as extracting metal from ore, natural sources such as volcanoes, and locomotives, ships and other vehicles and heavy equipment that burn fuel with a high sulfur content. Hence, statement 2 is not correct.
- SO2 can affect both health and the environment. Short-term exposures to SO2 can harm the human respiratory system and make breathing difficult. People with asthma, particularly children, are sensitive to these effects of SO2. Hence, statement 3 is correct.

With reference to Sulfur Dioxide(SO2) Pollution, consider the followin...
Statement 1: The largest source of SO2 in the atmosphere is the burning of fossil fuels by power plants and other industrial facilities.
This statement is correct. The burning of fossil fuels, such as coal and oil, by power plants and industrial facilities is the primary source of sulfur dioxide (SO2) pollution. When these fuels are burned, the sulfur present in them reacts with oxygen to form SO2. This gas is then released into the atmosphere, contributing to air pollution.
Statement 2: There are no natural sources of sulfur dioxide pollution.
This statement is incorrect. While human activities, particularly the burning of fossil fuels, are the major sources of SO2 pollution, there are also natural sources of this gas. Volcanic eruptions are one of the significant natural sources of sulfur dioxide. When a volcano erupts, it releases large amounts of SO2 into the atmosphere. Other natural sources include geothermal vents and marine emissions. However, compared to anthropogenic sources, natural sources contribute relatively less to overall SO2 pollution.
Statement 3: Short-term exposures to SO2 can harm the human respiratory system and make breathing difficult.
This statement is correct. Short-term exposure to SO2 can have adverse effects on human health, particularly on the respiratory system. When individuals are exposed to high levels of SO2, they may experience respiratory symptoms such as coughing, wheezing, shortness of breath, and chest tightness. SO2 can also exacerbate existing respiratory conditions such as asthma. Prolonged or repeated exposure to high levels of SO2 can lead to more severe respiratory problems and may increase the risk of respiratory infections and diseases.
In conclusion, statement 1 and statement 3 are correct. The largest source of SO2 in the atmosphere is the burning of fossil fuels by power plants and other industrial facilities. Short-term exposure to SO2 can harm the human respiratory system and make breathing difficult. However, statement 2 is incorrect as there are natural sources of sulfur dioxide pollution, although they contribute less compared to human activities. Therefore, the correct option is (c) 1 and 3 only.
