This study presents the results of research on water exchange and the environmental capacities of total suspended sediment (TSS), inorganic nutrients (PO 4 3-, NO 3 and NH 4 + ), and heavy metals (As, Hg, Cu, Cd, Pb, and Zn) in the receiving water of the Bach Dang estuary area. The results showed that the volumes of TSS, nutrients, and heavy metals in the waters met their potential carrying capacities. During the aquaculture processes in the wet season, the TSS and NO 3 factors polluted the

During the dry season, only the NO 3 factor was polluted in the water body, with an average value of 0.096gN/m 3 , and the other factors were not polluted in the water environment.
