NO2 exposure can lead to premature death, respiratory & circulatory illness: Report

  • Nitrogen dioxide (NO2) can have a significant impact on health. The air pollutant can lead to premature death from respiratory and circulatory illness, confirmed a new scientific review.
  • It can also deteriorate the health of people living with respiratory or cardiovascular diseases, stated the review commissioned by Health and Environment Alliance (HEAL), a European non-profit.
  • NO2 exposure can lead to respiratory and circulatory premature death (from both short- and long-term exposure), to the development of asthma in children and adults, to bronchitis in children
  • The review, recently published on HEAL website, also observed that the knowledge about the health effects of NO2 has increased significantly over the last 10-15 years.
  • In addition, studies are now able to distinguish between health impacts caused by NO2 and that by other pollutants, including particulate matter or PM2.5, it further stated.
  • Other sectors of NO2 emissions include energy production and agriculture, as well as industry and utility service. The briefing also zooms in on Poland, one of the most polluted countries in Europe. NO2 pollution here has been leading to a high health burden.
  • Given the urgency to act on the large health burden from air pollution, HEAL advocated for a change in the legally binding limit of NO2 to 10 micrograms per cubic metre (μg / m3) annual average for the maximum concentration by 2030. This aligns with the recommendation of the World Health Organization (WHO).
  • In 2021, WHO redefined the threshold of NO2 and made it more stringent. The annual NO2 guideline is now four times tighter than the 2005 limit of 40 μg / m3.
  • The review also advocated improved information dissemination by sending out alerts on NO2 peak pollution levels and associated health risks, as well as regular information on the health effects of NO2.
  • Moreover, it suggested improving air quality indices to include information on health risks and vulnerable groups. The review also recommended monitoring of smaller geographic areas and locations frequented by vulnerable groups (such as children) and air pollution hotspots.
  • High levels of NO2 were observed in seven Air Quality Index monitoring stations of Kolkata
  • The primary pollutants of concern are NO2, carbon monoxide, ozone, sulphur dioxide and methane.

Nitrogen Dioxide(NO2):

  • Nitrogen Dioxide(NO2) belongs to one of the highly reactive gases known as oxides of nitrogen or nitrogen oxides (NOx). Other nitrogen oxides include nitrous acid and nitric acid.
  • Formation: NO2 is formed when fossil fuels like coal, oil, gas and diesel are burned at high temperatures. It is also formed during the burning of wood and natural gases.

Effects of NO2

Health effects

  • Breathing air with a high concentration of NO2 can irritate airways in the human respiratory system. Such exposures can aggravate respiratory diseases particularly asthma.
  • NO2 along with other NOx reacts with other chemicals in the air to form both particulate matter and ozone. Both of these are also harmful to the respiratory system.

Environmental effects:

  • NO2 and other NOx interact with water, oxygen and other chemicals in the atmosphere and form acid rain. Acid rain harms sensitive ecosystems such as lakes and forests.
  • The nitrate particles make the air hazy and create visibility challenges.
  • NOx in the atmosphere contributes to nutrient pollution in coastal waters.

Leachate spill in Aravalis: activists write to Haryana rights body

  • A group of environmental activists has written to the Haryana Human Rights Commission (HHRC) drawing its attention to the alarming levels of toxic pollutants caused by leachate spilling over to the Aravalis from the Bandhwari landfill site in Gurugram.
  • The samples were collected from an abandoned mining pit measuring around 2.5 acres during the visit of HHRC chairman Deep Bhatia in May.
  • The high presence of toxic substances, such as fluoride and chloride, in the Aravalis due to the leachate spill.
  • “The substances were present several times over permissible limits, posing health hazards to residents of neighbouring villages by way of contaminating the groundwater and wild animals drinking the leachate,” the letter said.
  • While chloride is harmful for human consumption, the high level of fluoride could damage the bones of humans and animals, it pointed out.
  • The activists added that the leachate collecting in the mining pit was close to the underground aquifers and led to contamination of ground water.

43 new implementing partners empanelled under SAMARTH

All-gold performance! India tops medals tally; all 4 students bag gold at International Biology Olympiad

International Biology Olympiad

  • It is a biological Olympiad for pre-university students under the age 20, and is one of the most well-known International Science Olympiads.
  • The first IBO was held in Czechoslovakia in 1990, and it has since been held annually.
  • The competition has gradually expanded to include more than 75 participating countries across five continents.
  • All participating countries send the four winners of their National Biology Olympiad to the IBO, usually accompanied by two adults who are members of the international jury, for the duration of the competition.
  • To select these top four life science contestants for this international competition, all member countries host Biology Olympiad competitions in typically 3-5 consecutively more difficult national competition rounds.
  • As a consequence, this leads to a trickle-down effect, engaging more than 1 million students worldwide in life science each year.
  • Every year it is being organised by a different country.
  • India organized this Olympiad in 2008

Life on Venus? Here''s what new evidence of phosphine in clouds indicates

Phosphine

  • Phosphine on Earth is developed naturally by bacteria that live in very low-oxygen environments.
  • To produce phosphine, Earth bacteria take up phosphate from minerals or biological material and add hydrogen.
  • It is also called as hydrogen phosphide.
  • Properties
    • It is a colourless, flammable, extremely toxic gas with a disagreeable garlic like odour.
    • It is formed by the action of a strong base or hot water on white phosphorus or by the reaction of water with calcium phosphide (Ca3P2).
    • It is structurally similar to ammonia(NH3), but phosphine is a much poorer solvent than ammonia and is much less soluble in water.
  • Uses of Phosphine
    • It is used in semiconductor and plastics industries, in the production of a flame retardant, and as a pesticide in stored grain.

Venus

  • It is Earth’s closest planetary neighbour.
  • Similar in structure but slightly smaller than Earth, it is the second planet from the sun.
  • It is wrapped in a thick, toxic atmosphere that traps in heat.
  • Its surface temperatures reach a scorching 880 degrees Fahrenheit (471 degrees Celsius).
  • It rotates very slowly on its axis – one day on Venus lasts 243 Earth days.
  • Unlike the other planets in our solar system, Venus spins clockwise on its axis.

In a first, Navy submarine periscope refurbished indigenously with CSIO in Chandigarh executing the project

Periscope

  • It is an optical instrument used in land and sea warfare, submarine navigation, and elsewhere to enable an observer to see his surroundings while remaining undercover, behind armor, or submerged.
  • Submarines have periscopes so that people inside can see what is on the surface of the water.
  • Construction and Working Principle:
    • Periscopes can be constructed using a pair of flat mirrors or prisms and a rectangular hollow tube that has a viewing window at the top and bottom of the tube.
    • The mirrors within this structure are fixed at an angle of 45o at the two ends of the rectangular hollow.
    • A periscope is a useful example of the law of reflection at work. It’s important that your mirrors are placed at a 45° angle, because light always reflects away from a mirror at the same angle that it hits it.
    • In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle.
    • This sends light directly down the tube and onto the lower mirror. This mirror, also at a 45° angle, reflects light directly to your eye.
  • A simple periscope only requires mirrors, whereas a more complicated periscope utilizes prisms rather than mirrors.
  • The periscopes used in submarine applications are complex, typically requiring the use of tubes that are at least 10 meters in length to achieve a greater range of scope.

India had the second highest Schengen visa rejection in 2022, costing INR 90 crore

Schengen Visa

  • It is an official document mandatory for some non-Europeans to travel to all the 27 countries which are part of the Schengen area.
  • Once granted, this visa allows the traveller to cross the borders of the other member-states without going through identity checks at the border.
  • This type of visa is issued by one of the Schengen States and allows you to visit any of the Schengen countries for a duration of up to 90 days in total within 180 days.

Schengen Area

  • The Schengen Area, or Schengen Countries Zone, is a group of 27 European nations that have abolished their internal borders, for the free and unrestricted movement of people.
  • Members of this area include: 23 of the 27 EU member states (except for Bulgaria, Cyprus, Ireland and Romania) and all members of the European Free Trade Association (Iceland, Liechtenstein, Norway and Switzerland).
  • Switzerland, Iceland, and Norway are not in the EU but are inside of the Schengen Area.
  • Being part of this area means that countries:
    • do not carry out checks at their internal borders, except in cases of specific threats;
    • carry out harmonized controls at their external borders, based on clearly defined criteria.

''Fifth of suspected money mule cases involve under-21s''

Money Muling

  • A money mule is someone who transfers or moves illegally acquired money on behalf of someone else.
  • Criminals recruit money mules to help launder proceeds derived from online scams and frauds or crimes like human trafficking and drug trafficking.
  • Money mules add layers of distance between crime victims and criminals, which makes it harder for law enforcement to accurately trace money trails.
  • Money mules can move funds in various ways, including through bank accounts, cashier’s checks, virtual currency, prepaid debit cards, or money service businesses.
  • Some money mules know they are supporting criminal enterprises; others are unaware that they are helping criminals’ profit.
  • When such frauds are reported, the money mule becomes the target of police investigations.
  • Money mules often receive a commission for their serviceor they might provide assistance because they believe they have a trusting relationship with the individual who is asking for help.

''E-way Bill will bring big change in gold trade,'' says Finance Minister K N Balagopal

  • An e-way bill, short form for electronic way bill, is a permit needed for inter-state and intra-state transportation of goods worth more than Rs. 50,000.
  • It contains details of the goods, the consignor, the recipient and the transporter.
  • It can be electronically generated through the Goods and Services Tax Network (GSTN).
  • When an eway bill is generated, a unique E-way Bill Number (EBN) is allocated and is available to the supplier, recipient, and the transporter.
  • Working:
    • E-way bill must be raised before the goods are shipped and should include details of the goods, their consignor, recipient and transporter.
    • Though check-posts have been abolished under GST, a consignment can be intercepted at any point for the verification of its E-way bill, for all inter-State and intra-State movement of goods.
    • If a consignment is found without an E-way bill, a penalty of ₹10,000 or tax sought to be evaded, whichever is greater, can be levied.
  • Coverage:
    • The GST e-way bill became mandatory from April 1, 2018 for all inter-state transport of goods valued above Rs 50,000.
    • Starting from April 15, 2018, it was made compulsory for the moving goods within a state in a phased manner.
  • Validity: The e-way bill’s validity varies depending on the distance that the goods have to travel. Typically, the bill’s validity is one day for every 100 km of movement of goods.
  • Goods excluded from e-way bill’s ambit: Perishable items (such as meat, milk and milk products and fruits and vegetables), gold and silver jewellery, cooking gas cylinders, raw silk, wool and handlooms.
  • Who should generate an eWay Bill?
    • Registered Person: E-Way bill must be generated when there is a movement of goods of more than Rs 50,000 in value to or from a registered person. A Registered person or the transporter may choose to generate and carry EWay bill even if the value of goods is less than Rs 50,000.
    • Unregistered Persons: Unregistered persons are also required to generate e-Way Bill. However, where a supply is made by an unregistered person to a registered person, the receiver will have to ensure all the compliances are met as if they were the supplier.
    • Transporter: Transporters carrying goods by road, air, rail, etc. also need to generate e-Way Bill if the supplier has not generated an e-Way Bill.
