Question

What were the causes of air pollution in calcutta during mid 19th century

Answer 1

Causes of air pollution in Calcutta:

Calcutta is the capital of West Bengal. The major air pollution was attributed to urban urbanization combined with poor governmental response to urbanization.  If the pollutant is a volatile substance, but most of the time when the pollutant is dissolved or mixed with the water, when evaporation occurs any waste caught in the water will be left behind. This causes the water pollution to become worse with time.
