Even though the state is inching close to a kerosene-free status, the existing supply of the combustible oil is far from meeting the Centre’s directive of bringing down the sulphur content from 2.5% (2,500 parts per million) to 0.10% (100 parts per million), a reduction of 96%. As a result, up to 15% of the sulphur and carbon monoxide load in Mumbai’s air is due to domestic burning – mainly kerosene used in slums and surrounding rural areas – forcing Mumbaikars to breathe the poisonous gas.
It’s been almost four years since the central Environment ministry’s notification directed petroleum companies to bring down sulphur content in kerosene. However, only a miniscule quota of kerosene alloted to the army has been converted to the expected sulphur standards, say activists.
Sulfur dioxide emitted from kerosene use irritates skin and mucous membranes of eyes, nose, throat, and lungs. High concentrations of SO2 can cause inflammation and irritation of the Respiratory System. In addition tosulphur dioxide, kerosene heaters also emit carbon dioxide, carbon monoxide and nitrogen dioxide. Breathing these substances can pose Health risks.
