Abstract
The enormous increase in the usage of mobile phone telecommunication has led to the growing number of telecommunication Base Transceiver stations (BTS) commonly located within residential areas, thereby exposing residents to their possible negative effects. These effects, especially on residents in Osogbo, Nigeria, have not been given adequate attention in the literature. Hence, the study set out to investigate perceived environmental effects of BTS on the residents in Osogbo, Nigeria. Both stratified and convenience sampling techniques were used in collecting data for the study. The study adopted the statutory stratification of the
study area into three zones, such as the core, intermediate/transition zones and the periphery. Six neighbourhoods having TBS, comprising two from each zone, were purposively selected: Oja Oba and Gbemu in the Core, Kelebe and Uniosun area in the intermediate and GRA and Oroki Estate in the periphery. One BTS was purposively selected from each of the six selected communities. All buildings within 300 metre radius of the existing 34 telecommunication base transceiver stations in Osogbo were identified to be 1900. However, there were 355 residential buildings within 300m radius of the BTS in the selected communities. Therefore 150 residential buildings representing 42.3% were selected through systematic random sampling technique, from where household heads were purposively selected and sampled with the aid of a set of pre-tested questionnaire. Data collected were analyzed using descriptive and inferential statistics such as frequency count, percentages, cross tabulation, Relative Impact
Index (RII) and correlation. Findings revealed that t residents considered Noise emanating from the BTS generating plant (RII = 3.75 and MD = 1.00) and Vibration (RII = 3.61 and MD = 0.86) as the major environmental effect of BTS. The study also revealed a statistically significant correlation between BTS location and headache (r = 0.168** at p = 0.000 levels, and BTS location and sleeplessness (r = 0.063** and p = 0.000) indicate that the more the residents are closer to the BTS the higher the level of occurrence of headache and sleeplessness. The study concluded that BTS should not be located in areas less than 300 meters to
residential buildingsĀ
