Because of its toxicity, persistence with in environment, and bioaccumulative behavior, heavy metals are known as environmental pollutants. Toxic contamination by heavy metals of terrestrial and aquatic ecosystems seems to be an ecological issue of concern to human health. Metals, as pervasive contaminants, remain within environment and harm food systems. The buildup of highly unsafe toxic metals in biosphere poses a health risk to its users, especially humans. This chapter thoroughly explains the many heavy metal components as toxic components, with a focus on environmental longevity, toxic effects for living organisms, and bioaccumulative potential. The bioaccumulation of such metals is explored, as well as the consequences for public health. The most dangerous metalloids and heavy metals in the environment comprise Nickel (Ni), Chromium (Cr), Copper (Cu), Cadmium (Cd), Zinc (Zn), Lead (Pb), Arsenic (As) and Mercury (Hg). Such components’ trophic transmission in terrestrial and aquatic food webs/chains has significant ramifications for animals and human beings. This is critical to analyze and analyze the quantities of possibly hazardous metalloids and heavy metals in multiple ecological sections as well as in indigenous biota. A thorough examination of ecotoxicology and environmental chemistry of dangerous metalloids and heavy metals reveals significant actions must be done to reduce their influence on public health and the environment.
