Water Quality Assessment Using Benthic Macroinvertebrates In Saigon River and Its Tributaries, Vietnam

Abstract

This study to enhance the discussion about the usefulness of benthic macroinvertebrates for water quality assessment in Saigon River and its tributaries. Data from 16 sites were used as a representative example for Saigon River and its tributaries in the area of basin over 4,500 km², the length through provinces of Tay Ninh, Binh Phuoc, Binh Duong, and HoChiMinh City of about 280 km. The data covered the period of dry and rainy seasons in 2015, the survey sampled 16 sites (32 events) of the Saigon River and its tributaries selected. To implement this evaluation, the analyses were based on MRC methods and classifications these improved by the scientific group.

Both univariate and multivariate analysis were used to examine the spatial patterns of water quality and biological groups. The results demonstrated that these organisms could be applied to describe the ecological health in the Saigon River and its tributaries
