Heavy Metal Pollution in India: Current Trends and Perspectives

Heavy metal pollution represents a critical environmental and public health concern, particularly in rapidly developing regions of the world such as India. The increased rate of industrialization has accelerated the rate of release of heavy metals in the environment. This issue reverberates through various sectors, affecting not only the ecological balance but also the health and well-being of communities. Research on heavy metal pollution in India offers insights for policy-making, environmental management, and public health initiatives, addressing sources, distribution, ecological impacts, and health risks. A substantial body of research has documented the primary anthropogenic sources of heavy metals, which include industrial discharges, vehicular emissions, agricultural practices, and unregulated waste disposal. Observations show alarming concentrations of metals such as lead, arsenic, mercury, and cadmium in soil, water, and air in various regions across India Additionally, the health repercussions for local populations have been a focal point of research, with several studies linking heavy metal exposure to chronic diseases, neurological disorders, and developmental issues in children. Several environmental studies have been carried out in the earlier years of the century focusing on the contamination and the remediation methods. The current review paper aims to give an overview of the heavy metal pollution status in India for the past decade. A brief discussion on the regulations governing heavy metal pollution in India is included in the paper. Keywords: Heavy Metal, India, Pollution, Control Measures
