How much time will it take for the dust and pollution to dissipate?
The time period of particles being suspended in the air depends on nature; if there is heavy rainfall the next day, then the particles will come down to the ground much faster, and if we don’t have rainfall, then they will remain suspended for many days. In fact, another thing they could have done is to have a layer of showers all around this building, which would have prevented these particles from dissipating into the surroundings. When buildings are demolished in western countries, they create a circle, a ring of showers all around, which traps the particles from getting out. So, if there is heavy rain tomorrow evening, a lot of particles will come down and the pollution levels will decline. On the other hand, if it continues to remain dry, then it will remain suspended and will travel long distances.
