VILLAGE SMOKE

ACTIVITY 2: Pick up your pencils and match the fuel with its correct fuel efficiency % and its CO2

How many cigarettes does Rani‘s kitchen smoke in a day?
p78_1.jpg (1750 bytes)Rani has six people in her family. Cooking for everyone requires 1kg of fuel wood per head. Now every kg emits as much as 129 mg of Carbon Monoxide (CO). A cigarette, on the other hand, emits 58.8 mg of CO. So now all you have to calculate is, in terms of CO emissions, how many cigarettes would have to be smoked in the kitchen to match the wood smoke emissions?

black_arrow.jpg (1709 bytes) America’s Environmental Protection Agency (EPA) estimates that wood smoke is 12 times more carcinogenic than tobacco smoke and it attacks the body cells 40 times longer than tobacco smoke.

black_arrow.jpg (1709 bytes) A fireplace operating for an hour, burning 4 kg of wood during that time, generates 4,300 times more carcinogenic particles than 30 cigarettes.

ACTIVITY 2: Pick up your pencils and match the fuel with its correct fuel efficiency % and its CO2 emissions (gms per megajoule of energy delivered). How many did you get right?
