| Abstract: | Coastal aquaculture contributes significantly to the local economy of many countries however water quality issues in the coastal regions are threatening the sustainability of this economic activity. This paper presents the analysis of seven heavy metals (HM) in surface seawater and wastewater from the Red River coastal aquaculture zone during 2019-2020. HM concentrations (μg.L-1) from 72 seawater samples were: Zn: 60.76 (0.5-188.0); Cu: 26.91 (0.10-96.0); Pb: 7.27 (0.8-31.2); Cr: 6.71 (0.6-28.4); As: 1.38 (0.15-5.78); Cd: 0.44 (0.04-2.41); and Hg: 0.34 (0.02-1.39). All mean values of HM in seawater were lower than the Vietnam regulatory limits for aquaculture seawater although high individual HM concentrations were found in some isolated seawater samples. Concerning wastewater quality, only mean As concentration was higher than the Vietnam regulatory limit for surface water quality, despite the fact that high concentrations of other individual HM were observed. The PCA analysis on the entire dataset of seawater and wastewater samples revealed that HM concentrations in seawater originate from various sources including human activities and natural conditions. The total potential ecological risk index (averaging 18.6; from 7.48 to 39.05) for the Red River coastal zone is in the low range. These results provide a scientific basis for better management of the coastal environment which is important for the sustainable development of the aquaculture industry in this area.; (Copyright © 2022 Elsevier Ltd.
