The PCDD/PCDF emission inventory in Jordan: Aqaba city


​It is essential to develop proper emission inventories for the PCDD/PCDFs pollutants in Jordan in order to assess the possible effects of these pollutants on the environment. This study presents PCDD/PCDF emission inventory in Aqaba using a standardized toolkit developed by UNEP Chemicals. The total emission rate in Aqaba was estimated as 0.875 g TEQ yr–1. The reference date for this inventory is the year 2012. The category with the highest estimated emission is the transport sector (i.e. Diesel engines). Transport sector was ranked first to contribute to nearly 64.3% of total emissions to air. Heat and Power Generation contribute to nearly 5.6% of the total emission to air. Disposal and land filling is estimated to be the only source of dioxin emissions to water and highest estimated emission to residues with annual release of 0.007 g TEQ yr–1 for water and 0.110 g TEQ yr–1 for residues. Sewage/sewage treatment contributes to nearly 43% of the total emission to water and 98% to residue. Open water dumping contributes to nearly 57% of the total emission to water. Open Burning Processes is estimated to be the only significant source of dioxin emission to land through the 77 accidental fires in houses and factories, and 50 accidental fires in vehicles which annually release 0.003 g TEQ yr–1.
