Professor, who measures air pollution when he starts coughing at the metro stops. Dr. Mikdat Kadıoğlu found that the stations were 3 times more dirty. Kadıoğlu called for “Get on the subway with a sensitive allergy to dust with a mask”.
While recent medical studies reveal that cardiovascular diseases are associated with air pollution, especially fine particle (PM2.5) pollution, the PM2.5 average should not exceed 25 micrograms / cubic meter, according to the World Health Organization. Another pollution measure PM 10 average should not exceed 50 micrograms / cubic meter for a healthy life.
However, Prof. According to the measurements shared by Kadıoğlu the day before, these values are exceeded in metro and Marmaray stations. Kadıoğlu, who measured his handheld device at his home in Üsküdar on Sunday, found that the PM 2,5 rate was 23.
After going to Marmaray Station in Üsküdar, Kadıoğlu made another measurement at the entrance of the station. The device stated here that the rate of PM 2.5 is 25 micrograms / cubic meter and the rate of PM 10 is 34 micrograms / cubic meter. While these values were below the WHO levels, the rate of pollution was tripled when the station was reached. At the station, PM 3 rate; Measuring the rate of 2.5 micrograms / cubic meter and PM 87 as 10 micrograms / cubic meter. Dr. Kadıoğlu found that the PM 124 level was 2,5 micrograms in the wagon.
Evaluating the tests he gave to Cihat Aslan from Milliyet newspaper, Kadıoğlu said, “There is a special air pollution in subways all over the world. I wanted to do this test because I was impressed. On the subway, I noticed that I cough more. Curious, I measured. My measurement is an instant measurement. The particulate matter 2.5 level increases as I approach the station. The reason may be insufficient ventilation. What are the countries in the world doing and how are they struggling, this should be asked to the experts. There may be solutions such as ventilation, cleaning, braking system. It is beneficial for those who are sensitive to dust to enter with a mask.”
President of Turkish Thoracic Society Dr. Hasan Yildirim said the following about the measurement in the stations:
“Particle pollution caused by friction can occur at subway stations. For this, ventilation should be good and pollution sources should be reduced as much as possible. In general, particle pollution is known to have very negative effects on human health, especially heart-lung health. PM 2.5 is a diameter that can go all the way to the end of the lung and then get into the bloodstream and affect the whole body. There is a risk of developing asthma, COPD and heart diseases when air pollution is taken intensely in an individual with no disease. Authorities need to take action. If the result is correct, this is an alarming situation. What are the sources, where should the particles come from? "
Professor of Meteorology Engineering, Istanbul Technical University (ITU). Dr. Hüseyin Toros pointed out that the air of all cities is dirty according to the World Health Organization. Toros said, “As the train moves in the metro station, dust gets into the air. Accumulation may occur at station waiting points. Along the train path inside, there is dust in the inner cabinets and it is carried by the wind. It can be accumulating where passengers are waiting. Dangerous situation for those with upper respiratory disease. The most important feature of PM 2.5 is that it can easily enter our respiratory systems since it is very small. Therefore, when he breathes, he can go from the lungs to the circulatory system and the brain. Serious dangers can be faced. The advantage is that the passengers do not wait too long. But the security guards there are good at wearing masks. We should lower the values of 20-30 in Istanbul in the coming periods. ”
Istanbul Metropolitan Municipality, Prof. After Kadıoğlu's sharing, it was learned that he started a study on air quality in the subways. – Nationality
