  • Arunachali yak the first to be registered as new breed


  • Yaks, found in the mountainous regions of Arunachal Pradesh, have been registered by the Karnal-based National Bureau of Animal Genetics Resources (NBAGR) as a distinct breed known as Arunachali yak, this being the first instance of such a registration in the country. Union agriculture minister Radha Mohan Singh will formally award the recognition in New Delhi on Wednesday to the representatives of National Research Centre on Yak (NRCY) based at Dirang in Arunachal Pradesh.


  • The study found that Arunachali yaks are characterized by their predominantly black body colour and the high fat content in their milk which sometimes goes up to 7.45%. A lactating Arunachali yak produces, on an average, 1.3 kg milk per day. Though the milk is comparatively of poor quantity, it is compensated by the high fat content which makes it useful to produce different milk products.


  • However, scientific interventions, especially in the areas of breeding and rearing, have been able to slow down the decline of population as Arunachali yaks still remain the main source of livelihood for many Brokpas (yak rearers). West Kameng and Tawang are mainly dominated by the Monpa community, which treats the yaks as an asset for the rural economy, and rears these animals in organized farms or semi-migratory systems.

  • Dust mitigation plan must for firms


  • The Environment Ministry has made it mandatory for companies seeking environment clearance to ensure that they put in place a dust mitigation plan.


  • The requirements, specified in a gazette notification on January 25, say that roads leading to or at construction sites must be paved and black-topped. There could be no soil excavation without adequate dust mitigation measures in place. No loose soil, sand, construction waste could be left uncovered. A water sprinkling system was mandatory, and the measures taken should be prominently displayed at the construction site. Moreover, the grinding and cutting of building materials in open area were prohibited and no uncovered vehicles carrying construction material and waste would be permitted.


  • The standards were developed by the Central Pollution Control Board as part of the National Ambient Air Quality Standards (NAAQS), and will now empower the organisation to fine companies and agencies for not complying with norms.


  • Road dust contributed 56% of all PM10 pollution, while it was 38% for PM2.5.


  • Before PM2.5 became the focus of attention — for its role in lodging itself in the lungs and for being a key component of diesel emissions — dust was the key villain for a long time. Dust is a generic term for a vast mix of metals and non-metals — silicon, aluminium, titanium, manganese, copper, barium, antimony, selenium and zinc.


Gk bit  – PM (particulate matter)


  • PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope.


Particle pollution includes:



  • PM10 : inhalable particles, with diameters that are generally 10 micrometers and smaller; and


  • 5: fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller.



  • The average human hair is about 70 micrometers in diameter – making it 30 times larger than the largest fine particle.
