文摘The changes of 109 analytical methods for surface water in the past 20 years since the implementation of Environmental Quality Standards for Surface Water(GB 3838-2002)were analyzed.Concidering with the analysis of specific items in the quality standard,it is suggested that the monograph method and the general method(the general method is moved to the standard collection of general rules and standards)can be combined when the analytical method is newly formulated and revised in the future;the limit table of the quality standard or pollution source emission standard is moved to the collection of general rules and standards,and the referenced analysis method standards are deleted.The description of analysis method standard is more succinct,and the structure of the whole ecological environment standard system is clearer.
