  • For the first time, ‘Geochemical Baseline Atlas of India’ developed by CSIR-National Geophysical Research Institute (NGRI) for use by policy makers to assess environmental damage was released.
  • The atlas consisting 45 maps of metals, oxides and elements present in top and bottom soils across India will serve as a reference against which future generations of the country would be able to assess the chemical compositional changes on Earth’s surface.
  • These maps help in finding out future contamination caused by industries or other bodies which cause pollution.
  • The maps have been prepared for 22 metals. With a glance at it, one can get to know regions with high and low concentrations of a metal. For instance, tanneries release chromium. By going through the map of chromium, policy makers will get to know regions with high concentration of it. Policy makers should not allow tanneries in those regions.
  • The atlas will be given to International Union of Global Sciences (IUGS), which is preparing global maps.
  • IUGS is a non-governmental scientific organization of 121 member nations which promotes and encourages the study of geological problems, and facilitates international and interdisciplinary cooperation in the earth sciences. India is a member.
