When he started coughing at the metro stops, he started measuring air pollution. Dr. Mikdat Kadıoğlu has determined that the stations are more dirty than 3 floors. Kadıoğlu, "Dose allergy sensitive to dust with a mask on the subway," he called.

While recent medical studies have shown that cardiovascular diseases are associated with air pollution, particularly fine particle (PM2.5) pollution, the PM2.5 average should not exceed 25 micrograms / cubic meter, according to the World Health Organization. Another measure of pollution PM 10 average for a healthy life should not exceed 50 micrograms / cubic meter.

However, Prof. According to the measurements shared by Kadıoğlu the previous day, these values ​​are surpassed in metro and Marmaray stations. Kadıoğlu, who made a measurement with his handheld device at his home in Üsküdar on Sunday, determined that the ratio of PM 2,5 is 23.

Kadıoğlu then went to Marmaray Station in Üsküdar and made a measurement again at the station entrance. Here, the PM 2.5 ratio is 25 micrograms / cubic meter and the PM 10 ratio is 34 micrograms / cubic meter. While these values ​​remain below WHO levels, the pollution rate multiplied by 3 when landing at the station. At the station, PM shows the ratio of 2.5; 87 microgram / cubic meter, PM 10 ratio is measured as 124 microgram / cubic meter. Dr. Kadıoğlu, PM 2,5 level in the wagon 49 micrograms were determined.

Milliyet newspaperKadıoğlu evaluated Cihat Aslan's tests and said, “There is a special air pollution in the subways all over the world. I wanted to do this test because I was impressed. On the way to the subway I noticed that I cough more. I was wondering, measuring. My measurement is an instant measurement. The 2.5 level of particulate matter increases when I approach the station. The reason may be insufficient ventilation. What the countries in the world are doing, how it is struggling to be asked to experts. Ventilation, cleaning, braking systems, such as solutions. Those who are sensitive to dust should benefit from the mask. ”

President of Turkish Thoracic Society Dr. Hasan Yildirim said the following about the measurement in the stations:

“There may be a friction-induced particle pollution in subway stations. This requires good ventilation and reduced pollution sources as much as possible. Particulate pollution in general is known to have very negative effects on human health, especially on heart-lung health. PM 2.5 is a diameter that can affect the whole body by going to the extreme end of the lungs and then entering the bloodstream. There is a risk of asthma, COPD and heart disease when air pollution is intensely removed in an individual without any disease. The authorities need to take action. This is an alarming condition if the result is correct. We need to look at what the sources are and where the particles come from. ”

“Staff should wear a mask”
Istanbul Technical University (ITU) Meteorological Engineering Department Professor. Dr. Hüseyin Toros, according to the World Health Organization, drew attention to the polluted air of all cities. Os As the train moves in the subway station, the dust mixes with the air. Accumulation may occur at station waiting points. There is dust in the inner cabins and carried by the wind along the train track inside. It may mean that it is accumulating in places where passengers are waiting. Dangerous for people with upper respiratory distress. The most important feature of PM 2.5 is that it can easily enter our breathing systems because it is very small. Therefore, when you breathe, it can go from the lungs to the circulatory system and the brain. Serious hazards may be encountered. The advantage is that passengers do not wait long. But the security guards there should be wearing masks. We have to reduce the values ​​of 20-30 in Istanbul in the coming periods ”.

Istanbul Metropolitan Municipality, Prof. Following the sharing of Kadıoğlu'un learned that the study of air quality in the subway.
