摘要

采石场是一个小型工业,生产用于建筑的材料,从而为该国的国内生产总值(GDP)做出贡献。开展这项研究是为了评估采石场对奥贡州奥达达地方政府地区Kenta Logemo村居民的社会经济和健康影响。采样在采石场周围的三个不同距离(100,200,300米)和1000米(对照)进行。监测的空气质量是(气体成分)CO2 NO2, CO,火山有机化合物(VOC)和颗粒物(PM)和噪音水平。向工人和居民发放了30份调查问卷。结果表明,气体污染物在100 m处更为明显,不同距离间差异不显著(p > 0.05),均低于联邦环境部(FmEnv)的限值。在监测的三种颗粒物和距离中,200 m处的PM10 (137.1 ug/m3)最高。与采石场的距离无显著差异(p > 0.05)。噪音水平为59.3至86.3分贝(A),高于对照组(50分贝)。8db (A),但低于FmEnv限制(90db (A))。调查问卷分析显示,植被(40.0%)和动物(46.7%)濒临灭绝和受到威胁,粮食或经济作物被沙尘覆盖(30.0%)。水体受味道、颜色和浑浊度影响(63.3%)。所患疾病为卡他炎(53.3%)和眼睛刺激(46.7%)。综上所述,采石场周围没有受到CO2 NO2, CO, VOC, PM和噪音的污染,但采石场的活动对居民的健康和社会经济有显著影响,从而提高了经济地位。

Assessment of the Socio-Economic and Health Impact of Quarrying on the Inhabitants of Kenta Logemo Village in Odeda Local Government Area, Ogun State, Nigeria
Quarry is a small scale industry generating materials used for construction, thus contributing to the Gross Domestic Product (GDP) of the country. This study was carried out to evaluate the socio-economic and health impact of quarry on the inhabitants of Kenta Logemo Village in Odeda Local Government Area, Ogun State. The sampling was carried out in three different distances (100, 200, 300 m) around the quarry site and 1000 m (control). The air quality monitored are (gaseous component) CO2 NO2, CO, volcanic organic compound (VOC) and particulate matters (PM) and noise level. Thirty copies of questionnaire were administered to the workers and inhabitants. The result showed that the gaseous pollutants were more pronounced at 100 m and there were no significant differences (p > 0.05) among the distances and they were below Federal Ministry of Environment (FmEnv) limit. The PM10 at 200 m (137.1 ug/m3 ) was highest among three types of particulate matters and distances monitored. There were no significant differences (p > 0.05) across distances from the quarry. Noise level ranges from 59.3 to 86.3 dB(A) and higher than the control (50. 8 dB(A) but below FmEnv limit (90 dB(A). The analysis of the questionnaire revealed that the vegetation (40.0 %) and animal (46.7 %) were into extinction and threatened and dust (30.0 %) covered food or cash crops. Water bodies were affected by taste, colour and turbidity (63.3 %). Among the diseases suffered were catarrh (53.3 %) and eye irritation (46.7 %). In conclusion, the surrounding of the quarry is not polluted with CO2 NO2, CO, VOC, PM and noise but there is significant effect of the activity of quarry on the health and socio-economic of the inhabitants hence, improved the economic status.
