What did the prayer tunnel reveal about Tehran's air pollution? | When car tires and brakes also pollute the air.
Three scientific studies on the beer addressed the issue of air pollution from different angles.
In one of the latest studies related to Tehran's air pollution, the researchers chose Tehran's Nayaish Tunnel to study the pollutants caused by traffic.
According to the results of this study, traffic pollution is not only a product of burning gasoline. Even a car that performs better in terms of emissions can still contribute to particle production through tires, brakes and traffic on the asphalt.
According to the results of another study, subway passengers received the lowest inhalation dose of PM2.5 with an average of 2.5 micrograms, but of the groups studied, pedestrians had the highest inhalation dose with an average of 20.7 micrograms.
Air pollution should be considered as a kind of hidden urban cost; Part of the cost is transferred to the treatment system, part is paid by the households and the other part appears in the form of reduced work productivity.
