Comment on An assessment of heavy metal contamination in the surface sediments of Ha Long Bay, Vietnam by Dang Hoai et al. (2020)

In a recent article, Dang Hoai et al. (Environ Earth Sci 79:436, 2020) present an assessment of heavy metal contamination in the surface sediments of Ha Long Bay. However, there are some inaccuracies in the analytical data used in their article. In addition, their approach for calculating the enrichment factor of elements is also inaccuracy caused by unreliable assumptions. Consequently, their assessments can influence the process of decision making regarding environmental management.
