2. National Pollution Control Day

Context: National pollution control day is observed every year on the 2nd of December in memory of the people who lost their lives due to the Bhopal gas tragedy. it is a day to instil awareness among people about environmental pollution and its disastrous consequences.

All You Need to Know About National Pollution Control Day


  • The ruins of the union carbide chemical plant in Bhopal are a testimony to the biggest industrial disaster in India.
  • On the intervening night of December 2nd and 3rd the accidental leak of poisonous methyl isocyanate gas from the same plant took away the lives of thousands within a few.
  • Taking lessons from this incident December the 2nd was marked as the national pollution control day. The day has become even more relevant today due to the ever-increasing pollution in the country.
  • It aims to create awareness about the pollution of water air soil and environment in general besides creating awareness about the industrial disasters.
  • The problem of air pollution and water pollution have worsened in the past few years in cities like Delhi. The smog appears as soon as the winters start and affects routine activities in many ways.
  • The combined effect of industrial emissions vehicular pollution and stubble burning transform the cities into a gas chamber.
  • Urban waste and industrial effluents are also affecting precious water resources as a result the graph of diseases like heart disease diabetes, lung cancer is rising consistently.
  • According to the state of global air 2020 report, in the year 2019 there have been more than one and a half million annual deaths in India due to such diseases across every age group.
  • The covet 19 pandemic has also highlighted the urgency to address the chronic problem of air pollution as the severity of the air pollution is also a reason behind the recent rise in the covet 19 cases in cities like Delhi.
  • There is significant impact both on mortality and morbidity and particularly several diseases are linked to air pollution for example
    • Chronic obstructive pulmonary disease,
    • Lung cancer,
    • Stroke ischemic,
    • Heart disease,
    • Diabetes mellitus and
    • Lower respiratory infections.
  • We need to really be serious and take adjacent you know actions to reduce air pollutions to protect only our health and just to summarize that means that we need to consider air pollution as a health problem.
  • Many acts and rules are in place to control pollution at different levels and many programs are also being run under the central pollution control board but the effective implementation of these acts and rules calls for public participation people have to be aware of the impacts of the pollution 

3.  IIT Kanpur- New hourglass-shaped meta-structure

Context:  According to the religious beliefs of Hindus, the very first sound in the universe was produced by the Damru of Lord Shiva. Now inspired by the shape of the Damru of Lord Shiva, scientists at IIT Kanpur have developed a new hourglass shaped meta structure that can be used in the lattice unit for controlling sound wave propagation.

IIT Kanpur Researchers develop 'Damaru' Inspired Lattice that finds  applications in stealth submarines,high speed trains


  • The micro structured hourglass shaped structures have been developed in the smart materials laboratory of IIT Kanpur using additive manufacturing.
  • These structures were found to absorb and control different frequencies of sound waves during lab testing.
  • If you look at this structure this is an hourglass structure. what is unique in this particular case is that the entire structure is actually micro structured inside and if you look at this microstructure in a bigger scale what you would find is that it is going to have some such structures which are like honeycomb structures.
  • We have prepared this as the lattices so you can imagine that in a real-life system once we scale it down to a very very small scale these situations will be something like this that is there are there will be many many units of these types of systems which will be there and it will work like a waveguide such that we can control the transmission of waves at our will to them.
  • Applications:
    • Defence sector like in developing stealth helicopters and submarines to go undetected by radars  
    • To control the vibrations generated by high-speed vehicles like bullet trains future hyperloops etc as vibrations generated by vehicles are known to damage the constructions
    • To protect structures like bridges and buildings built along the tracks of high-speed vehicles by controlling the frequencies.
    • Effective in detecting the smallest tumor present in the body  
  • This work of IIT Kanpur is sponsored by a SPARC project of the ministry of education government of India.

4.  ISR, Gandhinagar

Context:  With the devastation caused by the 2001 Bhuj earthquake an acute need was felt for dedicated seismological research in the state of Gujarat to enable the sustained accelerated development that was envisaged across the state as a result the institute of seismological research was established by the Gujarat government as a centre of excellence in modern seismological research today we'll visit this institute to see how it is pursuing dedicated research in the field of seismology to minimize damage due to earthquakes.


  • Institute of seismological research situated in Gandhinagar Gujarat is a premier research center dedicated exclusively to earthquake studies run under the department of science and technology government of Gujarat.  
  • After the devastating 2001 earthquake and budge the establishment of the institute was approved by the state government in 2003 and ISR was established in 2006 as a center of excellence and modern seismological research.
  • Since its inception the institute has made unprecedented progress in its facilities to conduct R&D in near
    • Real time seismology
