  • Gases covered under the norms are: Carbon monoxide, Hydrocarbons, oxides of nitrogen (NOx) and Particulate matter

BS VI vs BS IV

  • NOx for BS VI-grade diesel engines and petrol engines will be brought down by 70% and 25%.
  • Reduces the particulate Matter (PM) limit by 80% from BS IV for diesel vehicles and introduces PM limit for petrol vehicles.
  • The sulphur traces in BS VI fuel is five times lower- a reduction of 80%.

Related Terms

Black Carbon

  • It is a solid particle or aerosol (and not a gas).
  • It results from incomplete combustion of fossil fuels and biomass.
  • They absorb light and about a million times more energy than CO2. 
  • Considered as the second largest contributor to climate change after CO2.
  • It is short-lived  in the atmosphere and when it falls to earth, it darkens the surface of snow and ice, reducing their albedo (the reflecting power of a surface), warming the snow and hastening melting.
  • BC concentration in the Gangotri region increased by 400 times during summer- resulting from agriculture burning , forest fires etc.

Brown Carbon

  • Brown carbon (BrC) is a carbonaceous aerosol which absorbs solar radiation over a broad range of wavelengths .

Vizag gas leak: What is styrene?

It is a flammable liquid that is used in the manufacturing of polystyrene plastics, fiberglass, rubber, and latex. Styrene is also found in vehicle exhaust, cigarette smoke, and in natural foods like fruits and vegetables.

Short-term exposure to the substance can result in respiratory problems, irritation in the eyes, irritation in the mucous membrane, and gastrointestinal issues.

Long-term exposure could drastically affect the central nervous system and lead to other related problems like peripheral neuropathy. It could also lead to cancer and depression in some cases.

Report on Lead Poisoning by UNICEF

  • UNICEF and  Pure Earth have released a report- “The Toxic Truth: Children’s exposure to lead pollution undermines a generation of potential”.

Key Findings

  • Lead poisoning is affecting children on a “massive and previously unknown scale”.
  • Around 1 in 3 children – up to 800 million globally – have blood lead levels at, or above, 5 micrograms per decilitre (µg/dL), the amount at which action is required.
  • Nearly half of these children live in South Asia.
  • The report notes that informal and substandard recycling of lead-acid batteries is a leading contributor to lead poisoning in children living in low and middle-income countries, which have experienced a three-fold increase in the number of vehicles since 2000.

Lead

  • Lead is a potent neurotoxin that causes irreparable harm to children’s brains.
  • It is particularly destructive to babies and children under the age of 5 as it damages their brain before they have had the opportunity to fully develop, causing them lifelong neurological, cognitive and physical impairment.
  • WHO has identified lead as 1 of 10 chemicals of major public health concern.
  • WHO has joined with  the United Nations Environment Programme to form the Global Alliance to Eliminate Lead Paint. 
  • Sources of childhood lead exposure – Lead acid batteries, lead in water from the use of leaded pipes; lead from active industry, such as mining and battery recycling; lead-based paint and pigments; leaded gasoline,  lead solder in food cans; and lead in spices, cosmetics, toys and other consumer products.

The effect of the total (anthropogenic + natural) aerosols is called aerosol radiative effect or total aerosol forcing. 

Effect of Aerosols

  • Aerosols affect climate in multiple ways. Aerosol absorbs or scatters radiation in the atmosphere (so-called direct effect).
  • Aerosols, except dust, interfere mainly with solar radiation.
  • Some aerosols act as cloud condensation nuclei (CCN), thus affecting cloud albedo and lifetime (so-called indirect effect).
  • Dark color aerosols can be deposited on sea ice, snow packs and glaciers, thus darkening the snow and ice surfaces, and enhancing the absorption of sunlight (so-called surface darkening effect).
  • Some of the aerosols can absorb sunlight efficiently and heat the atmosphere. This heating can burn cloud (so-called semi-direct effect).
