For context, an Air Quality Index or AQI of 0-50 represents ‘good’ quality of air while 51-100 is considered ‘moderate’ and 101-150 is deemed ‘dangerous’. “When do we call the air pollution level hazardous? The air quality has been constantly low, at an unhealthy level after the winter set in. No regulation in the construction work, brickfields and, lack of control over vehicles causing air pollution, unplanned factories along with authorities not spraying water are the reasons behind the rise in air pollution, he said. Issuing an air pollution index will be helpful for people.”People should be more aware to evade the ill effects of air pollution, said Biswas Akhter Hossain, vice president of Asthma Association of Bangladesh.
