Sulfur dioxide is considered a serious air pollutant. SO2 emissions that lead to high concentrations of SO2 in the air generally also lead to the formation of other sulfur oxides (SOx). SO, can react with other compounds in the atmosphere to form small particles, and
these particles contribute to particulate matter (PM) pollution. Small particles may penetrate deeply into the lungs and in sufficient
quantity can contribute to health problems. Which of these is NOT a source of SO2 pollution?
A)
manufacture of cement
B)
extracting metal from ore
burning fossil fuels by power plants
D)
trains, ships and heavy equipment that burn high sulfur content fuel
