Brown carbon ‘tarballs’ found in the Himalayan atmosphere

A study has found Tarballs found in the Himalaya-Tibetan Plateau.

The percentage of the tarballs increased on days of upper levels of pollution and will contribute to the hastening of glacial melt and global warming.


  • Tarballs are small light-absorbing, carbonaceous particles formed because of the burning of biomass or fossil fuels that deposit on snow and ice.
  • They hasten glacial melt.
  • They are formed from brown carbon, emitted during the burning of fossil fuel
  • Tarballs were emitted from biomass burning in the Indo-Gangetic Plain.


Tarballs from long-range transport are often a crucial component affecting the climatic effect and would correspond to a considerable influence on the glacial melting of the Himalayas region.

Bio-decomposer technique

The bio-decomposer technique also known as Pusa Decomposer has shown success in converting stubble into manure.

Developed under:

The guidance of the PUSA Institute  


  • Pusa Decomposer is a mix of seven fungi that produce enzymes to digest cellulose, lignin, and pectin in paddy straw.
  • The fungi thrive at 30-32 degrees Celsius, this is also the temperature when paddy is harvested and wheat is sown.


  • A liquid formulation is formed using decomposer capsules and fermenting it over 8-10 days 
  • The mixture is then sprayed on fields with crop stubble to ensure speedy bio-decomposition of the stubble.
  • For 25 liter of the liquid mixture is mixed with 4 capsules, jaggery, and chickpea flour is to be mixed, and the mixture is sufficient to cover 1 hectare of land.
  • The process completes in about 20 days. 


  • Improves the fertility of soil and productivity of the soil as the stubble works as manure and compost for the crops and lesser fertilizer consumption is required in the future.
  • It is practical, efficient, and effective, cheaper, doable, and to stop stubble burning.
  • This is an eco-friendly and environmentally relevant technology.

SMOG levels witness an unprecedented rise

The national capital experienced unprecedented levels of smog due to increased pollution levels. 


  • Smog is an extremely harmful mixture of fog, dust, and air pollutants
  • These air pollutants may be volatile organic compounds, sulfur dioxide, nitrogen dioxide, carbon monoxide, and PM10s, etc.
  • Smog can be caused by:
  1. Large amounts of coal-burning in an area
  2. Slash-and-burning of crops (a major source in Delhi)
  3. Pollutants that form smog arise and generate from power plants, automobile exhausts, fireworks, even paint, hairspray, charcoal starter fluid, and plastic popcorn packaging.
    • They combine with sunlight to form a dense layer of ground-level ozone.
    • Smog formation depends on is also closely linked with temperature, sunshine, and calm winds. 
    • Smog formation is faster on warmer days than other days.

  • Smog causes lung damage 

Additional Information:

  • Ozone present high in the atmosphere is beneficial, but when nearer the surface, it can cause irritating health effects.


  • Sulfurous smog, or the London smog, develops due to the high concentration of sulfur oxides in the air.
  • Photochemical smog can be found when sunlight reacts with oxides of nitrogen and at least one volatile organic compound (VOC) in the atmosphere.

Health impacts:

  1. Long time inhalation of the smog  of time can inflame your breathing passage
  2. Smog causes inflamed lungs which leads to the secretion of interleukin-6 which can cause blood clots in people, cardiac and respiratory disorders, leading to heart attacks or strokes.
  3. Smog can dry out the mucous membrane 
  4. It affects the body’s ability to resist infection, hence, increasing susceptibility to illness.
  5. It can decrease the level of UV radiation, leading to low production of important elements like Vitamin D.


Recently, a museum has been announced, which reflects the culture and heritage of the people living in char-chaporis, the ‘Miyas’ 


  • A char is a floating island 
  • Chaporis are low-lying flood-prone riverbanks.
  • Depending on the push and pull of the Brahmaputra, a char can become a chapori or vice versa, thus they are used interchangeably as they keep changing shapes
  •  These areas are marked by low development indices as they are prone to floods and erosion,
  • These areas are primarily occupied with  Bengali-origin Muslims, other communities like  Misings, Deoris, Kocharis, Nepalis also live here.

Additional Information:


  • The ‘Miya’  often used with a   derogatory connotation is used for the community comprising of the descendants of Muslim migrants from East Bengal (now Bangladesh) to Assam and form the Bengali speaking Muslim community, often also referred to as ‘char’ because of their habitat, ie., char-chapori.


  • Are a series of floating islands
  • Exclusive to the Loktak Lake in Manipur.
  • They are spread over a substantial part of the lake 
  • They are heterogeneous masses of soil, vegetation, and organic matter, in different stages of decay

Upwards of 100 beached whales saved off near the Sri Lankan coast 

More than 100 beached pilot whales saved off Sri Lanka


The rescue operation was conducted by the navy and received help from environmental protection officers, police, and local residents.

Additional Information:

Cetacean stranding, popularly known as beaching, refers to the phenomenon of dolphins and whales stranding themselves on beaches.

The reason is often unknown but there exist  a range of theories, including:

  • Changes in water temperature.
  • Irregularities in whales’ echolocation.
  • Geomagnetic disturbances.
  • Errors made in navigation.
  • Hunting too close to shore.
  • Sonar interference.
  • Inclement weather.
  • cetaceans to live in large groups with intricate social systems where communication plays an important role., The members of a group can respond to distress calls of members in distress and follow them to the beach, causing mass stranding.

Other  instances:

  • Tasmania in Australia - In September, one of the largest in the world.
  • The Chatham Islands, a New Zealand in 1918 The largest mass stranding in modern record 

Pilot Whales:

There are two species of pilot whales: 

  • Short-finned in tropical and warm-temperate regions, 
  • and long-finned pilot whales, inhabit colder waters.
  • IUCN Red List of Threatened Species: Data Deficient
