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”
