An Experimental-assessment of Human Exposure-levels to Aircraft Noise-hazards in the Neighbouring-environments of four Nigerian Airports

Post-Project Environmental Impact Evaluation of Ota Industrial Housing Estate on the Localized Environment and Environs in Ogun State, Nigeria

“…; which are aimed at achieving local consumerproduct sufficiency and balancing bilateral trade deficits with other nations, also come with adverse environmental impacts. More often than not, in most cases of unregulated industrialization, mining and natural resource exploration etc., the environment is at the receiving end, with man bearing the brunt, by paying the ultimate price with his health-due to the numerous associated hazardous environmental conditions including: Noise pollution [1], [2], [3]; low outdoor Air Quality Index [4], poor natural ventilation performance [5], inadequate indoor illumination [6], consumption of contaminated water [7] and [8], indoor exposure to radiological hazards from unexpected sources like building materials [9] and indiscriminate industrial waste disposal [10], [11], [12] [13], which can be significantly controlled by the safe recycling of wastes to transform them into useful products [14] and [15]. At the moment, these and a number of other factors are considered to be of critical importance, as both the Natural and the Built environmental experts clearly harp on the need to have them factored-in them in before, during and after the design and execution of developmental projects [16] and [17]; while prioritizing eco-friendly project execution methods & strategies over others [18].…”

A Study of Noise Pollution Measurements and Possible Effects on Public Health in Ota Metropolis, Nigeria

“…Notwithstanding, noise pollution remains a serious health concern in the study area (Ota, Nigeria) in particular and the entire planet [7], [8]. Some of the identified sources of noise pollution are loud music from concerts, religious buildings like churches and mosques, noise emitting generators [9], political rallies, road advertisement, traffic [10] and air transportation [11], sporting events, construction and industrial activities. In all the mentioned sources, areas that have high risk of noise pollution are residential places near to major roads [12] and airports and manufacturing industries [13]; for example, small scale industries [14], [15], steel rolling industries [16], oil and gas industry [17], [18] and so on.…”

City-wide Quality Assessment of Sandcrete Masonry Blocks Produced in Lagos, Ibadan and Abeokuta Metropolitan-cities in South-western Nigeria

“…The need to continuously study the effect(s) of minor and major variations in the 1:8 circa ratio and other constituents & their relative proportions in sandcrete blocks, has become critically important in many fields of engineering such as Noise (Sound) damping and Wireless telecommunication network (GSM) pathloss investigation in buildings. This is in view of the negative effects of exposure to hazardous Noise-levels from various sources including electricity generators, machineries and aerial vehicular systems [22], [23], [24], [25], [26]; and the usual/regular telecommunication network-improvement projects and activities [27], [28], [29], [30], [31], [32].…”

“…Furthermore, it is important to mention that, during the construction of a building with/without the use of sandcrete blocks [as the walling material], after the Structural-integrity evaluation-which is primarily considered, some other of issues of concern which are secondarily considered include Fire-resistance [37], [38] Safety & Ergonomics [39], [40], [41]; Natural illumination [42] and Thermal comfort/Ventilation [43]-which aside the relatively high amount of electric power required to electrify high-electricload household devices/appliances like water pumps, heaters, pressing-irons and refrigerators/freezers [44], [45]; will certainly help to reduce the overall electrical energy consumption of a building, particularly in highly populated (a 2019 estimate: > 200 million persons) and developing African country like Nigeria where constant supply of the yet inadequate electric-power generated still eludes the populace nearly six decades after independence from British imperialism [22], [25], [23], [46], [47], [48].…”
