Oct 03, 2016 Related to : GS Paper-3

Ans :


According to data released by World Health Organisation, about 6 lakhs deaths being caused annually in India by fine particulate matter pollution in the air. Though WHO estimate is only modelled estimate, but it highlighted the cause which alarming to Indian public health system.

Highlights of WHO report-

  • About 6 lakhs deaths in India could be attributed to particulate matter 2.5 micrometres or less in size.
  • Comprehensive measurement of PM2.5 is not yet being done and the linkages between pollution, disease and deaths need further study.
  • In India, residents in many urban areas are forced to breathe unhealthy levels of particulates, and the smallest of these PM10 and less can penetrate and get lodged deep in the lungs.
  • Data on fine particulates in India show that in several locations the pollutants come from burning of biomass, such as coal, fuel wood, farm litter and cow dung cakes.


  • In India air pollution, particularly in urban centres has reached alarmingly high level. Virtual discarding of the Construction and Demolition Waste Management Rules, notified to sustainably manage debris that is dumped in the cities, creating severe particulate pollution.
  • Ever increasing construction activities, urban mismanagement and not following pollution control methods are important reasons. In highly built-up areas, construction debris, road dust and vehicular exhaust add to the problem.
  • Comprehensive measurement of these particulates is currently absent in many cities, and in its absence its impact also overlooked till now.


  • The Environment Ministry has highlighted the role that debris can play as a resource. Municipal and government contracts must utilise up to 20% materials made from construction and demolition waste, and local authorities must place containers to hold debris.
  • India must provide cleaner fuels and scientifically designed cook stoves to those who have no option but to burn biomass on priority basis.
  • Greening the cities could be made a mission, involving civil society, with a focus on landscaping open spaces and paving all public areas to reduce dust.


India being developing country, it cannot afford the impact of particulate matter and should act to curb these dust particulates without any delay. WHO report on particulate matter is cause to worry. The recent WHO report on the terrible toll taken by particulates, should lead to intensified action.
