Abstract

This study was carried out in Odual Clan in Abua/Odual local government area of Rivers State, Nigeria, to determine the effect of deforestation on air quality and wildlife. Three air pollutants were measured at the study sites (CO2, CH4, PM) It was observed that the mean concentrations of CO2 (970.5000000ppm, 548.1250000ppm, 690.2500000ppm) in all the study sites were above the permissible limits by WHO. The mean concentration of Pm7 (17.6250 µg/m3) in the deforested area was significantly higher than those of the control (7.1250 µg/m3) and the residential area (11.2500 µg/m3). The mean concentration of PM10 ranges from 9.2500 µg/m3 to 21.1250 µg/m3 with the deforested area having the highest concentration. T-test revealed a significant difference in the mean concentration of TSP with the deforested area having the highest concentration of 24.5000 µg/m3. Results (68% of respondents) also revealed that there is a loss of wildlife species. The causes of degradation according to the results obtained are chain sawing, illegal farming, over exploitation and illegal mining; 36%, 2%, 26% and 6% respectively

河流州odual氏族主要毁林地点周围的空气质量评估和野生动物发病率

这项研究是在尼日利亚河流州Abua/Odual地方政府地区的Odual Clan进行的，以确定森林砍伐对空气质量和野生动物的影响。在研究点测量了3种空气污染物(CO2、CH4、PM)，发现所有研究点的CO2平均浓度(970.50000ppm、548.1250000ppm、690.2500000ppm)均高于WHO的允许限值。毁林区Pm7平均浓度(17.6250µg/m3)显著高于对照(7.1250µg/m3)和居民区(11.2500µg/m3)。PM10平均浓度在9.2500 ~ 21.1250µg/m3之间，以毁林区浓度最高。t检验显示，TSP平均浓度差异显著，毁林区浓度最高，为24.5000µg/m3。调查结果(68%的受访者)还显示，野生动物物种正在减少。根据所获得的结果，退化的原因是链锯，非法耕作，过度开采和非法采矿;分别为36%、2%、26%和6%
