Activity 3.3.1 Air Pollution Core Activity
Air Pollution Basics Sulfur Pollutants Sulfur dioxide or SO2 is one of the most important gaseous air pollutants that is colorless but pungent (Freedman, 2018). Humans are able to detect its bitter taste. Another sulfur gas is hydrogen sulfide or H2S and smells like rotten eggs. They become oxidized to other compounds when they enter the atmosphere and create sulfate. The typical time that sulfur dioxide stays in the atmosphere is four days which makes it more able to spread for long distances (Freedman, 2018). This is called long-range transportation of air pollution or LRTAP. Most atmospheric sulfate occurs in tiny particles. Volcanoes are natural sources of emission for sulfur gases. Haze is also a way of LRTAP. Anthropogenic emissions of sulfur dioxide have increased a lot over time ever since the Industrial Revolution began (Freedman, 2018). The number of emissions are different for every country depending on certain factors and criteria. Most developed countries have started...
