In the beginning of the interview, Zhang Weifemg started bydescribing the general information about China’s use of fuels.Weifemg stated that, “China is a very industrial country. Most ofthese industries consume fossil fuels such as coal and petroleum”.From my knowledge, I established that it is the combustion of fossilfuels leads to emission of greenhouse gases including CO2, SO2, andNO2.
Weifemg further illustrated that the numerous motor vehicles in Chinaare notorious for CO2 emissions. “For instance, in Beijing alonethere are over 4 million automobiles emitting greenhouse gases”.The construction industry is also another source of air pollution inChina. Although on a smaller scale, construction work raises dustthereby polluting the air. Another pollutant worth mentioning is theAsian dust from Gobi desert and other deserts in Northern China.
From the discussion in the interview, I established that smog is atoxic type of fog caused by particulate matter made up of S02,Cadmium, Mercury and lead. On asking the source for the smog inChina, Weifemg stated that, “The main source of smog in China isthe industrial emissions due to the combustion of fossil fuels”.Using the Weifemg’s response, the issue of smog could be a timebomb considering the high population density in China’s cities.
The emission of greenhouse gases leads to the formation of acid rain.For instance, when S02 in the air mixes with rainwater, it comes downas weak sulfuric acid that corrodes the roofs of buildings and thechlorophyll of green plants. Smog contains toxic elements and heavymetals that are responsible for respiratory diseases and cancer ofthe lungs. Smog also impairs visibility and it may lead to airaccidents. There is no major step taken by Chinese authorities tostop air pollution. It is only recently that the government raised ared flag regarding the issue of smog in China.
