College (affiliated to Kazi Nazrul University), Raniganj, Paschim Bardhaman, West Bengal, India > Case Study 2020 9 1 2021 01 22 Air pollution in urban India has become a great concern now-a-days. Most of the Indian cities and metropolis are situated on the edge of health risk because of atmospheric contamination. Patna - the capital of Bihar - is notorious for air pollution. The main culprit of air pollution of this city is vehicular emission. The present study has been carried out to assess the air pollution load of Patna city that resulted mainly due to vehicular emission and to propose some remedial options to the planners and decision makers to solve this issue. It is a survey based study that has been carried out at different sampling locations of Patna city and necessary primary data were collected. The study revealed that the atmospheric condition of Patna city is deteriorating day by day due to vehicular emission and if this situation persists for long the inhabitants of the region will fall in great distress. Hence immediate and fruitful steps should be taken to remediate this situation. Copyright@ International Science Community Association
