Tóm tắt:

As a consequence of rapid urbanization and industrialization, pollutants have increased in both quantity and diversity in the water environment. Monitoring plays a key role in prevention of negative impacts from potential environmental risks. Currently, physical and chemical analysis is considered as the popular methods for monitoring. Yet it is obvious that these methods require costly expenditure, high sampling frequency and difficult to evaluate the environmental status as well as to forecast the movement of chemical concentration. Using macro-invertebrates as bio-indicators has been evaluated as the advantageous method for testing water quality since the processed data can mirror water quality based on the ecological and biological characteristics. Biological indices named BMWP (biological monitoring working party) and ASPT (average score per taxon) have been initialized and adopted in temperature-countries and have shown remarkable advantages in assessment of water quality. In this paper, we present the initial results in applying BMWP and ASPT to monitor water quality of rivers in Central Region during 5 years from 2007 to 2011.

Abstract:

Using macro-invertebrates as bio-indicators has been evaluated as the advantageous method for testing water quality since the processed data can mirror water quality based on the ecological and biological characteristics.
