Since the city was built on marshy land, the resulting fog combined with smoke, and generated a thick black smog.
High levels of pollution was due to the huge population that used dung and wood as fuel in their daily lives.
Main pollutants were the industries and establishments that used steam engines run on coal.
Rice mills of Tollygunge began to burn rice husk instead of coal, leading to black soot which fell like drizzling rain.
