    (Department of Environmental Management, Nasarawa State University Keffi, 2021-01-04) Inyaka, Godwin Igie; Alkali, Mohammed; Emeodilichi, Mba H.; Alfred, Udofia Udeme
    This study assessed dust concentration, elements and compounds at limestone quarry site and the aim was to determine the level of air pollution due to dust generated from quarrying activities, the elements and risks it poses to health and the environment. Dust samples were collected using a 224-PCXR4 sample pump and analyzed for concentrations and harmful elements/compounds constituents. The results shows that dust concentration at the quarry site was quite high on the average 51.56 mg/m3, when compared with the limit 10 mg/m3 and the study revealed that the crushing plant had more dust concentration of 92.5 mg/m3 than all the other working areas. Quarry pit had the second highest concentration, followed by garage and the office areas in descending order, three main harmful elements/compound detected in the sampled dust are; silicon dioxide with a mean concentration of 0.62 mg/m3, chromium 5.92 mg/m3 and lead 9.24 mg/m3 respectively. The study recommends that environmental management systems, which include a dust management plan, should be employed at the quarries in order to mitigate dust generation. Particularly during drilling/blasting of rocks and at the crushing plant.

    CHARCOAL ENERGY CONSUMPTION PATTERN IN URBAN HOUSEHOLDS OF FCT ABUJA, NIGERIA
    (Department of Environmental Management, Nasarawa State University Keffi, 2021-01-06) Emeodilichi, Mba H.; Alkali, Mohammed; Alfred, Udofia Udeme; Inyaka, Godwin Igie
    This paper considers those factors contributing to charcoal consumption in the urban households in capital city of Nigeria using in-house questionnaire data collection from ninety households. Thirty households each from three study areas namely; Maintam a, Garki and Kubwa, mapped out in three categories based on building designs; duplex houses, Terrence/flat apartment and bungalows, and demographic information like (marital statues, income, education and employment). The results shows that duplex and bungalows house designs consumes more of charcoal 39% and 51% respectively than 10% of terrence/flat apartment, same with married and high and low income earners which shows that charcoal consumption rates were higher for the households with more family members, high/low income and cooking frequency. This study shows the relevancy of charcoal in the urban area, also that income is an important variable and this study also suggest need for other variables like food choice, cost of living, household size and preference, same time recommend policies and means to address this charcoal consumption that poses great threats to our forest reserves which serves as carbon storage, water, air purification and also reduces the intensity of flooding events.
