Akther Institute of Forestry and Environmental Sciences, University of Chittagong Received: 02 September 2019 / Accepted: 26 November 2019 / Published online: 01 January 2020 ABSTRACT The study was conducted to estimate and describe air emissions generated from April 2017 to March 2018 by the in-land activities and cargo transportation of the Chittagong Port of Bangladesh, using activity-based approach. These emission sources include cargo handling equipment, head trucks and locomotives. The pollutants focused in this study are categorized into two groups: criteria pollutants consisting NO x , CO, SO 2 , Particulate matters and Black carbon, and greenhouse pollutants consisting of CO 2 , CH 4 and N 2 O. Head trucks are the major sources of all air emission (NO x 91.35%, CO 94.83%, PM 10 62.11%, PM 2.5 60.47%and CO 2 e 98.73%), demanding serious consideration to this sector.The locomotives cause the least emission among all sources and can be used as a tool to reduce emission from head trucks. About 3478.04tonne NO x , 1134.22 tonne CO, 31.09 tonne PM 10 , 30.97 tonne PM 2.5 , 22.82 tonne SO 2 , 23.88 tonne Black carbon, and 5141319.71 tonne of CO 2 e were released in the atmosphere during the study period due to the in-land port activities. Keywords:In-port shipping activity, Port emission, Criteria pollutant, Air pollution, CO 2 .
