Sulfur Isotope in Plants and Atmospheric Environmental Change

The sulfur is not merely one kind of air pollutant, but also is the plant growth essential nutritive elements. Sulfur isotope in plants can provide important information about the plants to absorb atmospheric sulfides as well as the metabolism of sulfur in plants. It plays an extremely important role in monitoring the short-term and long-term environmental change of the terrestrial biosphere. With the aid of the information of sulfur isotope, it can clarify the environmental change and its historical trend of the terrestrial ecosystem. Sulfur isotope in plants has already become a unique and powerful tool to study and analyze the sources and migration mechanisms of atmospheric sulfur pollution in the regional environment.
