    Air pollutants in/ from waste management sector in Tanzania
    (University of Dar es Salaam, 2008) Nkuwi, Imani Richard
    This study was to study was to develop inventory for the key air pollutants (CH4, NOx, ), N20, CO and NH3) for ) and NH3) for Waste Management Sector in Tanzania from 1995 to 1 emissions for greenhouse for greenhouse gases and non-greenhouse gases were calculated Intergovernmental Panternmental Panel on Climate Change (IPCC) and Air Pollution )n Network for Africa (rk for Africa (APINA) guidelines respectively. Municipal solid d amount of wastewater `of wastewater were estimated using the population of the inventory e the emission from collision from clinical waste used primary data on amount of clinical lected at Muhimbili National hospital. Generally, the results showed that the if emissions estimated frcns estimated from these key pollutants in this sector increased with 1 1995 to 2005. For exan2005. For example emission of methane from solid waste disposal from 13.30Gg in 1995.30Gg in 1995 to 18.18Gg in 2005 which 36%. Methane from 1 wastewater rose from Ater rose from 1.55Gg in 1995 to 2.00Gg in 2005 which is 29%. ,xide from human sewage i human sewage increased from 1.18Gg in 1995 to 1.74 in 2005 which whereas NH3 from defecatF13 from defecation urination practices rose from 40.1Gg in 1995 to in 2005 which is 39%.TI-vhich is 39%.The emissions from incineration of clinical waste was ly for 2005 since managers since management method started in late 2004. The P11410 emitted 3-g followed by S02 (266qd by SO2 (266Gg), NOx (262Gg) and CO (24.9Gg). Thus, emissions ste management sector cement sector contribute to the pollution of the atmosphere but not nt to cause alarm. This stut alarm. This study may have uncertainty due to adoption of emission times from IPCC and AP ,m IPCC and APINA guidelines because (i) country-specific emission (ii) there is inadequate data for quantities of solid wastes are not available. (ii) The available and disposed of (iii) there(used of (iii) there is inadequate information on amount of waste water candled at disposal sites. disposal sites. .-refore recommended that commended that air pollution inventory should be done for the waste ment sector in Tanzania an, r in Tanzania annually so as to keep track of emission problems for decisions making. Further making. Further studies on country-specific emission factors, activity of waste managed should be done. This can minimize the level of d statistics of waste manage inties and hence in prove reliability in inventories. Prove reliance im xm
