Abstract: Preliminary investigation of air quality parameters in Calabar was undertaken by the Atmospheric Research Team at the Department of Physics, University of Calabar under the sponsorship of Tertiary Education Trust Fund, TETFund in Nigeria. The investigation was initially designed to determine air quality indices in three major cities of the oil producing Niger Delta region of Nigeria where gas flaring and other environmental abuse have gone unabated for over four decades. However, due to paucity of funds, the study was limited to Calabar and its environs. This paper is a report of preliminary findings of a comprehensive data collection and analysis of criteria gases and particulate matter in Calabar. Both mobile and stationary equipment were used in the data collection process. The stationary facility consist of AQM65 which was mounted at the geo-environmental field station at the University of Calabar. The station lies at the heart of the city. The automated facility was programmed to

Abstract: This work aims in developing a technique to be used at large scale for treating leachates which are produced by compaction of Municipal Solid Waste (MSW) of Mohammedia city (Morocco). In order to avoid environment pollution, the MSW effluents are usually stored in basins before their treatment. However, sometimes these effluents are dumped directly in the landfill without any treatment, causing, hence, environmental problems. In the present work, anaerobic biological treatment, followed by aeration, were both used, to achieve removal of pollution load of fresh leachates from the MSW. Thus, high organic load effluents were treated by anaerobic process during 43 days, followed by intensive injection of 3.5 L of air per minute in 10 liters of leachate over a period of 30 days. The resulting characteristics of the treated leachate such as the COD, the BOD5 and the turbidity, were found to depend on the importance of the pollution load, and on the nature of the inorganic constituents initia
