Consider the following statements about black carbon:1. Black carbon is long lived climate pollutant.2. It is formed after incomplete combustion of fossil fuels.3. Southern India has a high burden of black carbon emission.Which of the statements given above is/are NOT correct?

[A] 1 and 2only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: C

Notes:

According to a study, Black Carbon has a significant adverse effect on human health and leads to premature mortality.

Key Findings of the Study:

The Indo-Gangetic plain has a high burden of black carbon with serious implications for regional climate and human health.
A 10-point increase in air pollution from black carbon led to an average 5% increase in mortality.
On the other hand, a similar rise in PM 2.5 led to an average 1% increase in mortality. Nitrogen dioxide (NO2) and Sulphur Dioxide (SO2) were both associated with a 2.3% and 1.3% increase in mortality.

About Black Carbon (BC):

Black carbon (BC) is a short-lived climate pollutant. It is the second-largest contributor to warming the planet after carbon dioxide (CO2).
Black carbon is formed through the incomplete combustion of fossil fuels, biofuel, and biomass.
Primary sources include emissions from diesel engines, cookstoves, wood burning and forest fires.
