In this study, the simultaneous determination of Co, Cd, Ni, Cu, and Pb was carried out as a color complex with 4-(2-pyridylazo) resorcinol in an aqueous solution under the assesting of machine learning. A partial least-squares multivariate linear regression and artificial neuron network for the analysis of mixtures of metals were developed. MATLAB is a powerful software machine learning program that was used to support matrix calculations and displays.

The presence of various types of contaminants such as heavy metals, emerging organic contaminants, pesticides, organic waste, organic dyes, radionuclide’s, fluorides, etc. cause water pollution. These pollutants are of concern to engineers, environmentalists and scientists. Due to the lack of freshwater, it is very important to recycle the wastewater after treatment to remove organic contaminates and heavy metal pollutants.

The results identified that fly ash could be primarily considered as hazardous waste with 5/14 heavy metal parameters exceed the limit from 1.7 to 9.5 times and needs to be collected and treated properly. This result is also quite similar to the studies that have been done in China, the US or Viet Nam. Thus, SEM/EDX method could be used for analyzing heavy metal components in fly ash samples of solid waste treatment plants.

Estuary sediments contain toxic heavy metals which can pollute coastal wetlands. Ba Che river estuary is a coastal wetland with an area of 2,844 ha, which is affected by wastes in Ba Che river water and aquacultures. In this study, the accumulation of heavy metals in the Ba Che river estuary was assessed based on the enrichment factor (EF), the geo-accumulation index (Igeo), and the ecological risk index (RI).

The Cuu Long delta is affected strongly by mass water from rivers of the MeKong river system such as Tieu, Dai, Ham Luong, Co Chien, Cung Hau, Dinh An and Tranh De (Hau river). The estuaries of Cuu Long delta are large with a huge amount of sediment (about 100 million tons per year) and high tide (about 4.2m) made the large tidal flats with high level of biodiversity, which is an important resource for aquaculture.

In the study "Distribution, fate and ecological toxicity of some heavy metals in sediment: A case study from Day river downstream, Vietnam" the 50 surface sediment samples were collected along Day River downstream in July 2018 and January 2019 (25 sampling sites) to clarify the status, movement and potential risk of some heavy metals (Cr, Pb, Cu, Cd and Hg). The receptor model of Principal Component Analysis (PCA) was applied to track the source types of these metals.
