Just lately the South Asian nation ranked probably the most polluted nation globally whereas its capital Dhaka grew to become the 2nd worst polluted metropolis, stated World Air High quality Index (AQI) Report revealed earlier this week.
Home and transboundary air pollution
The 2 main causes of air pollution are home and transboundary air air pollution, Dr. Shahriar Hossain, an setting knowledgeable, instructed Anadolu Company.
Referring to a latest discipline research, he stated, “Transboundary motion of air contributes a lot of the airborne pollution that journey a protracted distance and trigger undesirable air high quality degradation.”
