    Inventory of air pollutants for the agriculture and animal husbandry sectors in Tanzania
    (University of Dar es Salaam, 2008) Kipasika, Honest John
    This thesis is concerns the development of inventory of key air Pollutants from m or in Tanzania from 1995 to 2005. Pollutants were detected using the methodologies provided by In Panel of Climate Change (IPCC for greenhouse gases and) Air Pollution Information Network for Africa (APINA) non for - greenhouse gases. Activity data were gathered from key ministries (Ministry of Agriculture, Food Security and Cooperatives and Ministry of Livestock and Developments) and others from research organizations, regulatory bodies and NGOs such as National Bureau of Statistics (NBS), National Environmental Management Council (NEMC) and Centre for Energy, Environment, Science and Technology (CEEST). Using the best estimate and reasonable assumptions, emissions factors were obtained from the established national and international sources. The main sources of air pollutants were domestic livestock, rice cultivation, savanna burning, agricultural soil management and field burning of agricultural residues. Based on analysis, the inventory of the CH4, NH3, N20, NOR, CO, NMVOC, SO2, PM10 and PM2.5 were developed. The results show that the total annual emissions of CO burning sub sector lead the emissions by 56% from 1995 to 2005. It is followed by methane emissions (22%) and PK () (8%). The trend of emissions varied across the years due to changes in activities data such as annual crop productions, application of mineral fertilizers, soil-natural process, farm management practices and annual livestock populations. For example, CH4 and NH3 were increasing throughout the years of study while those of CO, SO2 and NMVOC emission were almost constant. we’re fluctuating; the N20, NOx, PM10 and PM2.5 emissions were almost constant.
