Nitrate exposure’s impact

  • A new World Bank report looks at the impact of water pollution worldwide.
  • In that one aspect covered is the long-term impact of ‘Nitrate’ exposure experienced during infancy.
  • Short-term exposure has almost negligible effect on adult height, but cumulative exposure over the first 3 years of life has considerable impact.
  • Nitrate pollution is caused by the overuse of nitrogenous fertilisers to boost yields.
  • It can be harmful if they leach into water or air.
  • In India, the Green Revolution of the 1960s kick-started the use of synthetic fertilisers.
  • An infant girl who has been exposed to nitrate levels above the safety threshold in the first 3 years experiences a 1-2cm decrease in her adult height.
  • Female adult height in India has increased by approximately 4cm over the last century.
  • A 1-2 cm loss means that nitrate exposure in infancy can wipe out almost half of this gain in height.
  • The report also found  that nitrate levels in groundwater aquifers exceeded permissible levels in more than 50% of the districts across 19 states.
