Heavy metals (HMs) contamination in soils and sediments (river/marine) and its impact on human health have induced a global consideration due to their bioaccumulation, non-biodegradability, toxicity and perseverance. The ecological risk assessment of HMs in soils and sediments have well studied in different countries, however there are very few studies in which ecological risk assessment of HMs has been compared in different countries. Therefore, the ecological risk of HMs (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn) in soils and sediment was assessed using the studies published during 2020 and 2021. The available data was for 308 sediment sampling sites in 17 countries (Australia, Azerbaijan, Bangladesh, China, Colombia, Egypt, Greece, India, Iran, Kenya, Malaysia, Mexico, Saudi Arabia, Sri Lanka, Nigeria, Pakistan and Turkey) and for 799 soil sampling sites in 17 countries (Belgrade, Brazil, Chile …
