Progress in Research on Stable Isotopes in Precipitation in China: A Review
At present,acid rain is one of the most serious environmental problems in the world.China has become the third largest heavy acid rain region in the world,behind Europe and North America.It is of great importance to study the chemical compositions,sources and their relative contribution of precipitation,which can provide scientific references for controlling the development trend of acid rain and formulating the corresponding policies.The isotopic composition is an effective method to identify the sources of substances in the precipitation.Acid deposition is resultant from SO2 and NOx emitted to the atmosphere.In addition,alkaline dust is another important component.Such alkaline dust can neutralize much of the acidity of the rain water.The application of S,N,and Sr isotope tracing sources of substances in precipitation is overviewed in this paper.Finally,future research is suggested.
