The bright orange flames of kerosene wick lamps used in millions of impoverished households around the world are significant sources of global warming and pollutants linked torespiratory diseases, according to a new study.
Lab and field work led by researchers at UC Berkeley and the University of Illinois at Urbana-Champaign showed that 7% to 9% of the kerosene consumed by the crude burners is converted to black carbon — a 20-fold increase over previous estimates, the study published online this month in the journal Environmental Science & Technology said.
One kilogram of black carbon, a byproduct of incomplete combustion that absorbs light and heats the atmosphere, produces as much warming in a month as 700 kilograms of carbon dioxide does in a century, the study said…
