PERSISTENT ORGANIC POLLUTANTS AND VEHICLE POLLUTION

PERSISTENT ORGANIC POLLUTANTS AND VEHICLE POLLUTION

VEHICLE POLLUTION

  • Vehicle pollution (also known as transport pollution or motor pollution) is the introduction of harmful materials into the environment by motor vehicles.
  • These materials, known as pollutants, have several bad effects on human health and the ecosystem.
  • Examples of such pollutants include carbon monoxide, nitrogen oxide, sulphur dioxide, VOCs and particulate matter.
  • Transportation is a major source of air pollution in many countries around the world due to high number of vehicles.
  • The Government of India has adopted emission standards for transport vehicles.
  • Bharat Stage Emission Standards (BSES) are emission standards instituted by the Central Government to regulate the output of air pollutants from internal combustion engines and spark-ignition engine equipments, including motor vehicles.
  • The standards and the timeline for implementation are set by the Central Pollution Control Board under MoEFCC.
  • The standards, based on European Regulations were first introduced in 2000.
  • Progressively, stringent norms have been rolled out since then. All new vehicles manufactured after the implementation of the norms have to be in compliance with the regulations.

Present Status of Bharat Stage (BS) Norms

  • The BS-IV emission standards were introduced for 13 major cities in April 2010. At present, BS-IV norms are applicable in 30 major cities.
  • The BS-IV norms have come into force nation-wide on March 31, 2017.                    PERSISTENT ORGANIC POLLUTANTS AND VEHICLE POLLUTION

Future Progress in Implementation

  • The Centre has notified that the Bharat Stage BS-VI emission standards for two-wheelers and four-wheelers will be implemented from April 2020 across the country.
  • With this, the government has decided to skip the BS-V emission standards and move directly to BS-VI from the BS-IV norms currently being followed in various cities.

Resistance by Industry

Two major industries are resisting direct introduction of BS-VI norms:

  • Oil refineries will have to invest substantially to upgrade the refining process.
  • The shift from BS-IV to BS-VI demands approximately Rs. 50,000- Rs. 80,000 crore from oil refineries.
  • Automobile industries will also be required to make high investments to produce vehicles with Lower emission levels.

PERSISTENT ORGANIC POLLUTANTS

  • The Persistent Organic Pollutants (POPs) are organic compounds that are resistant to environmental degradation.
  • The POPs bioaccumulate within human and other animal tissues and biomagnify at various levels in the food chains.
  • Stockholm Convention is an inter-governmental convention which identifies POPs and requires the nations to bar the use of POPs.
  • Twelve POPs have been listed under Stockholm Convention and these POPs are called ‘dirty dozen. It includes dichlorodiphenyltrichloroethane (DDT).
  • The DDT is used as an insecticide in agriculture. Its use has been banned now.                    PERSISTENT ORGANIC POLLUTANTS AND VEHICLE POLLUTION
