For example, if you live in the traffic-intensive Greater Taipei area and the less-traffic-intensive Pingtung area, there will be a significant difference in the proportion of emissions from pollution sources. Following the above principles, we compiled the relevant information from the latest TEDS10.0 emission query system provided by the Air Protection Department of the Environmental Protection Agency and the statistics on the number and density of motor vehicles in the environmental database of the Environmental Protection Agency.
Taking Taipei City, which has the highest color correction services density of locomotives in Taiwan, as an example, the proportion of locomotives in PM2.5 emission sources has increased to 8.28%, and Chiayi City, which has the second highest density, accounts for 9.24%, and its contribution to fine suspended particles is obvious. rise. chart1 Taiwan Smart Mobility Industry Association Watchmaking Percentage of PM2.5 in counties and cities with the highest locomotive density | Source: National Air Pollutant Emissions Inventory Information System of the Air Protection Department of the Environmental Protection Agency, Environmental Database of the Environmental Protection Agency In the same way, in the same county and city, due to the differences in population and traffic between different regions, the contribution of locomotive PM2.5 is also very different.
For example, according to the 104-108 editions of the Taichung City Air Pollution Control Plan , the total amount of PM2.5 emitted by locomotives is 310.51 metric tons per year. There are 29 administrative districts in Taichung City, and the highest emission proportion is Taiping District, which accounts for 28.53 metric tons per year. (9.2%), followed by Xitun District with 25.57 metric tons (8.2%). On the contrary, the lowest proportion of emissions is only 2.28 metric tons (0.7%) per year in the Eastern District, and the second lowest is only 3.17 metric tons (1%) per year in Daan District, showing that even within the same county and city, there is still a huge gap in the distribution of pollution sources.
