Effectiveness of Solutions The issue of air quality is handled fairly well by the different levels of governments as there are drops of the main air pollutants. On the right, it can be seen that annual maximum 1 hour average and 4 hour average concentrations for ozone are continually dropping. Also the graph below shows the reduction of the sources of air pollution are being reduced and the projection of the next ten years is also good with further reductions. These two graphs gives evidence that air pollution is declining rapidly and has been addressed effectively. |
