Perfluorotributylamine : Most Powerful Greenhouse Gas

History : 

  1. The newly discovered gas, perfluorotributylamine (PFTBA), has been in use by the electrical industry since the mid-20th century such as transistors and capacitors.
  2. Concentrations of PFTBA in the atmosphere are low – 0.18 parts per trillion in the Toronto area – compared to 400 parts per million for carbon dioxide. So PFTBA does not in any way displace the burning of fossil fuels such as oil and coal as the main drivers of climate change.

Occurrence 

The chemical, that does not occur naturally.Radiative efficiency describes how effective a molecule of a gas is at preventing long-wave radiation from escaping back into space. The higher the radiative efficiency, the greater that molecule can influence climate. This value is then multiplied by its atmospheric concentration in order to determine the total climate impact of a substance.PFTBA is a manmade chemical used for various applications in electronic equipment, electronic testing and as a heat transfer agent since the mid 20th century.

Effects

PFTBA remains in the atmosphere for about 500 years, and unlike carbon dioxide.A new greenhouse gas that is 7,000 times more powerful than carbon dioxide at warming the Earth.
