In urban areas, especially megacities such as Beijing and Shanghai, emissions from vehicles have become an increasing problem.In recent years, it has been observed that the emissions of long-regulated sulfur dioxide (SO2) and total suspended particulates (TSP, including particulate matter [PM10]), have passed their peak and are diminishing. The situation of fine particulate matter (PM2.5) and ground-level ozone (O3) concentration, however, is worsening. Regional air pollution problems are becoming significant. Sometimes vast regions, such as all of eastern and central China, are under very high concentrations of PM2.5 and O3.
