The WHO’s plan of action for reducing indoor pollutants is based on new findings, which show that the use of toxic(有毒的) fuels in inefficient stoves, space heaters or lights is to blame for many of these deaths.
Carlos Dora, an official in the WHO, says people should not use unprocessed coal indoors.He says, “Opening a window or door to let out the harmful air will not correct the situation. It will only pollute the outdoors. You can’t expect that a bit of ventilation(通风) is going to get rid of this. It is really about clean technologies and clean fuels. And, the fuel story has not been stressed enough so far in the global debate. So, that is the new thing. We should be going for clean fuels, avoiding coal and going for the solar.”
WHO officials say indoor pollution leads to early deaths from stroke, heart and lung disease and childhood lung cancer. These diseases can often result from high levels of fine particulate matter and carbon monoxide(一氧化碳) released by the burning of solid fuels. These fuels include wood, coal, animal waste, crop waste and charcoal. Women and girls are the main victims.
The United Nations found that more than 95 percent of households in subSaharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatemala and Peru, are also at risk.
WHO experts note some new, safe and lowcost technologies that could help are already available. But this is just a start. They are urging developing countries to use cleaner fuels and increase access to cleaner and more modern cooking and heating appliances.
