Heavy metal toxicity is a big hazard to water resources and is a regional problem for our four main areas of the planet. There are important benefits of bio associating contaminants using renewable sources such as microalgae. The diatoms are the most predominant and diverse phytoplankton community, representing 45% primary ocean productivity. In both fresh and marine water environments they have a ground-breaking impact in the biogeochemistry of metals. Diatoms are essential to degrade, detoxify and detoxify chemical waste and hazardous metals from contaminated sites. A diatom is primarily distinguished by the silicon-cell wall's unique ornamentation which is sustained and consistently replicated over generations. If the diatom cell outline and striation patterns will change, create teratological shapes, if subjected to various kinds of stress during reproductive processes. The goal of this review is to link abnormal morphology of the diatom cells to heavy metal stress with a view to greatly improving river assessment.
