The biosphere is the living objects’ natural world. It includes the planet and comprises surface portions of the lithosphere, the body and the hydrosphere. For species to live in the atmosphere, a reasonably homeostatic condition is important. To track any abnormal transition due to economic advancement and consequential growth of civilization, this includes the analysis of the chemical composition of air, water, and soil. Over the last few decades, the volume of water waste worldwide has risen. One of the most important water contamination sources is the application of extremely hazardous and non-degradable heavy metals (such as Lead, Cadmium, etc.) The effect on marine ecosystems is very fantastic. These heavy metals are taken explicitly from the water by water creatures, and indirectly by other animals belonging to the food chains. Since heavy metal ingestion is involved, certain physiological modifications are happening within the heavy metals such as reduction in growth and developmental defects and reduction in survival. Some organisms such as the Atlantic mackerel (Scomber scombrus) are used for calculation of heavy metal emissions as bioindicators and biomonitors. The purpose of this study is to discuss the significance of this organism in observing both the volume and quality aspects in relation to heavy metals, particularly lead and cadmium, in the water bodies' surroundings and how this heavy metal exposure can be avoided or managed.
