Soot comes from the incomplete combustion or coal, oil, woo d and other fuels In other words diesel engines, vehicle exha ust pipes, farming machines, construction equipment, or simp ly fires in grills, fireplaces, and stoves are potential sources of soot It appears in our daily life and can easily affect every on e of us a  Soot and global warming 2. _ Soot like all black things absorbs sunlight and heats u p the atmosphere According to recent research, it is t he second most damaging greenhouse gas after C02, a nd twice as harmful to the climate Although black ca rbon remains in the atmosphere for no more than seve n days it is particularly damaging to frozen areas Soo t emissions might be responsible for the quick meltin g of the Arctic Controlling black carbon can help to s low down global warming b  The effect of soot on human health 3. _ Soot does not only have an impact on globs warming and climate change, but is also unhealthy A soot parti cle is very tiny - smaller than dust and mould, and ab out 1/30 the width of a human hair It can easily go int o our bloodstream and lungs via the nose and throat.  As a result, breathing in the tiny particles car cause as thma attacks, heart disease, bronchitis and many other respiratory illnesses d  Ways to reduce soot emissions 4. _ Large quantities of man-made soot enter the atmosphere every year The effects are most damaging regionally, es pecially in South and East Asia, Latin America and part s of Africa In developing countries, reducing soot emis sions can be achieved by replacing traditional stoves wit h clean, alternative fuel cookers and heaters Installation of filters to remove black carbon from diesel vehicles ca n also reduce soot Changing to electric or hydrogen ve hicles will also reduce the impact on the environment • In conclusion, reducing black carbon will have immedia te benefits in slowing down global warming and the mel ting of the Arctic snow and ice It would also prevent m any soot-related deaths and illnesses Activity 3: Complete the sentences with no mo re than words know little about soot oil, wood, and other fuels second most damaging greenhouse gas smaller than dust and mould/very tiny clean, alternative fuel stoves Activity 4: Discussion Question: Are soot emissions a proble m in your community in Vietnam in general? • the effect of soot on the environment and human health • Soot does not only have an impact on glo bs warming and climate change, but is als o unhealthy.  • It can easily go into our bloodstream and l ungs via the nose and throat.  As a result, breathing in the tiny particles can cause a asthma attacks, heart disease, bronchitis a nd many other respiratory illnesses Consolidation soot emission absorb sunlight heat up the atmosphere SOOT POLLUTION The origin of soot Soot and global warming The effect of food on human health CONTENT Ways to reduce soot emission THANK YOU FOR YOUR ATTENTION ... respiratory illnesses d  Ways to reduce soot emissions 4. _ Large quantities of man-made soot enter the atmosphere every year The effects are most damaging regionally, es pecially in South and East Asia,... have immedia te benefits in slowing down global warming and the mel ting of the Arctic snow and ice It would also prevent m any soot-related deaths and illnesses Activity 3: Complete the sentences... of filters to remove black carbon from diesel vehicles ca n also reduce soot Changing to electric or hydrogen ve hicles will also reduce the impact on the environment • In conclusion, reducing
