AIR EMISSIONS FROM IN-LAND ACTIVITIES OF CHITTAGONG PORT OF BANGLADESH

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 NOx, CO, SO2, Particulate matters and Black carbon, and greenhouse pollutants consisting of CO2, CH4 and N2O. Head trucks are the major sources of all air emission (NOx 91.35%, CO 94.83%, PM1062.11%, PM2.5 60.47%and CO2e 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 NOx, 1134.22 tonne CO, 31.09 tonne PM10, 30.97 tonne PM2.5, 22.82 tonne SO2, 23.88 tonne Black carbon, and 5141319.71 tonne of CO2e were released in the atmosphere during the study period due to the in-land port activities.
