The study was undertaken at Mfamosing to evaluate the pre and post-cement production activities' impact on the environment. Data on climatic variables were obtained from Nigeria meteorological stations (NIMET) at Margaret Ekpo International Airport from 1966 - 2020. Insitu data on temperature, rainfall and relative humidity were collected for the study. Questionnaires were further distributed to the inhabitants of the area to actually identify the major problems associated with cement production in the study area. Direct observations were also done to determine changes in the immediate environment. The research findings revealed that the pre-production era 2002, showed a mean rainfall amount of 2719.98mm and 2832mm for the 1 st and 2 nd decade, which was lower than the post- production era that is the 3 rd , 4 th and 5 th decades with a rainfall amount of 2963.62mm, 2944.92mm and 3300.21mm respectively. Also, the pre-production era mean temperature during the 1 st and 2 nd decades from 1966 - 1985 were 26.7℃ and 26.84℃ respectively and were lower than the mean temperature during the post- production era by the 3 rd , 4 th and 5 th decades with temperature values of 26.98℃, 26.80℃, 27.23℃ respectively. Furthermore, the mean relative humidity for the 1 st and 2 nd decades were 85.55 percent and 85.77 percent which were also lower than that of the post- production era with values of 84.5 percent, 84.63 percent and 85.6 percent respectively. The researchers concluded that there is a difference in microclimatic conditions between the pre-cement and post-cement production area. We further recommended that the industry producing cement in the area should attach a chimney to its evacuation chamber to reduce the emission of greenhouse gases into the atmosphere.

Introduction The advent of industrial revolution in the seventeenth century presented itself with an unprecedented increase in the volume of pollutants in the atmosphere. Since then, their impacts have not only been felt in many urban centres * Corresponding Author: JoeObiefuna@Gmail.com, JoeObiefuna@Unical.edu.ng
