Abstract
The study on the development of air pollution inventory for the industrial sector in Tanzania from 1995 to 2005 was done to estimate the key pollutants which are emitted during production processes. Pollutants were identified using the methodologies provided by Intergovernmental Panel on Climate Change (IPCC) for greenhouse gases (GHG) and Air Pollution Information Network for Africa (APINA) for non-greenhouse gases. Activities data were gathered from the Ministry of Industry, Trade and Marketing, National Bureau of Statistics. Other sets were from the Centre for Energy, Environment, Science and Technology (CEEST).
The main pollution sources of Greenhouse gases (GHG) from this sector include cement production, metal production, alcohol beverages and solvent production. The gases considered were: NOx, CO2 CO, NMVOC, 502 and PM10. Generally, the results showed that the amount of emissions from this sector increased from year to year. Furthermore the percentage total annual emissions of CO2 from cement production topped the list with 90% contribution. It was followed by CO (7%), PM ° (2%), and 502 (1%), while NOx was almost zero. From this study, it can be concluded that the contribution of the industrial sector in the emissions of GHG or non-GHG is low compared to other sectors. Furthermore it is observed that the emissions trend was increasing annually and CO2 is the most significant pollutant.
