Exposure to Particulate Matter from Kerosene Lamps James Apple, Ryan Vicente, Andrea Yarberry, Nathan Lohse, Jenny Tracy and Dustin Poppendieck, Ph.D.
Health Issues Associated with Kerosene Lamps Burns Child poisoning due to inadvertent consumption Exposure to unburned fuel Compromised visual health due to sub- standard luminance Indoor air pollution?
How bad is indoor air in developing countries? PM 10 concentration ( g/m 3 ) Indoor Air – Biomass Stoves300-3,000 Outdoor Air – Major Cities in Developing Countries 150 USEPA50 European Union40 Geo Year Book 2006
Problem 1: Big Picture PM 2.5 health standards can be exceeded by an order of magnitude in homes using kerosene lamps Migration to improved lighting sources reduces exposure to particulate matter –Simple Wick => Hurricane => LED lights PM2.5 Ultrafines
Problem 2 What is the relative contribution to particulate matter inhalation if you use both a kerosene light and fuel based cook stove?
Take Home Message : Cook Stoves –10 th Global Disease Burden Intake of Particulate Matter from Simple Wick Lamps –~5 times less than cook stoves –~5 times more than ambient air Likely ancillary health benefits from transition to LED lighting
Health Issues Associated with Kerosene Lamps Burns Child poisoning due to inadvertent consumption Exposure to unburned fuel compromised visual health due to sub- standard luminance Indoor air pollution
Bottom Line: Indoor air pollution –Impacting health Marketing LED Lamps –Fewer respiratory health issues for consumer if NOT using fuel based cook stove Impacting countries GDP? –Subsidies? –Economic Incentives?
Problem 3 ~1.6 billion people ~1.5% of the worlds crude oil –38-77 billion liters of Kerosene Do kerosene lamps contribute a measureable amount to global warming?
What about Global Warming? After carbon dioxide what do we care about? –Methane –Black Carbon Removed in weeks rather than decades
Global Warming and Black Carbon Emissions 0.04- 0.33 Tg/year. –Global: 8 Tg/year –~ 2 Tg/year by residential solid fuel burning 0.5-4% of the global black carbon
