What is the difference between sulfur dioxide and carbon dioxide

They grow in exposed places such as rocks or tree bark, which means they easily absorb water and nutrients to grow there. Rainwater contains just enough nutrients to keep them alive. Air pollutants dissolved in rainwater, especially sulfur dioxide, can damage lichens and prevent them from growing. This makes lichens natural indicators of air pollution.

For example:. In places where no lichens are growing it is often a sign that the air is heavily polluted with sulfur dioxide.

The Journal of Chemical Thermodynamics , , Valderrama , Claudio A. How does SO 2 get in the air? SO 2 can affect both health and the environment. What are the health effects of SO 2? SO 2 emissions that lead to high concentrations of SO 2 in the air generally also lead to the formation of other sulfur oxides SO x.

SO x can react with other compounds in the atmosphere to form small particles. These particles contribute to particulate matter PM pollution. Small particles may penetrate deeply into the lungs and in sufficient quantity can contribute to health problems. SO 2 and other sulfur oxides can contribute to acid rain which can harm sensitive ecosystems.
