Passengers cover their noses and station attendants cry out...the air pollution of diesel vehicles entering Kaohsiung Station exceeds 17 times the limit
After the Kaohsiung Railway underground project, which cost nearly 100 billion , was opened to traffic in October last year, the PM2.5 concentration of fine suspended particulates on the underground platforms of Kaohsiung and Fengshan stations soared due to exhaust gas when the diesel-powered train on the South Loop line passed by. Passengers Covering the nose makes the station attendants even more miserable. It was detected on the spot that the PM2.5 concentration at Kaohsiung Station's train entering the station was the highest, which was 17 times the standard value.
"It's horrible!" said Huixiang Hong, founding chairman of the Pingtung Branch of the Environmental Protection Alliance. Taiwan Railway Fengshan Station and Kaohsiung Station are almost dangerous workplaces for Taiwan Railway employees. Wearing masks for self-protection is only a negative act, and the replacement should be accelerated. Diesel trains and stations with underground stations should not run diesel trains. "Don't expose passengers and staff to health risks."
In order to check the health of passengers, the United Daily News cooperated with Sun Yat-sen University on September 4th and 7th to carry out the "PM2.5 detection of fine aerosols at Kaohsiung Station and Fengshan Station."
The two-day monitoring results show that regardless of the type of vehicle, when the train enters Kaohsiung Station, the PM2.5 value will increase by an average of about 10 to 50 micrograms per cubic meter, but if it is a diesel train, the PM2.5 concentration in the station It can reach one hundred to six hundred in an instant, of which the highest instantaneous value at Kaohsiung Station is 611 micrograms, which is 17 times the air quality standard 35 of the Environmental Protection Agency. It takes five to ten minutes after the train leaves the station for the concentration to drop to General value.
It is understood that Taiwan Railways is also setting up air quality monitors at various stations. The locations of the Kaohsiung Station and Fengshan Station are near the ventilation equipment, and the data is relatively "beautiful". Associate Professor Chia C. Wang, the Director of the Aerosol Science Research Center at National Sun Yat-sen University, said that it is questionable whether it can represent the situation of the entire platform under the condition of good ventilation and diffusion, because the empty products will have different regional distribution.
