Abstract
This research work determined the emission characteristics and elemental composition of selected PVC ceiling
materials common in Nigerian markets especially during service. This research work determined the emission
characteristics and elemental composition of selected PVC ceiling materials common in Nigerian markets. The
emission data and elemental structure gave insight to appraise their suitability as ceiling materials. Three PVC
ceiling materials were used for this analysis: Nigerian made PVC, layered Composite PVC and white PVC.
Rutherford Backscattering Spectrometry (RBS) was performed to obtain the elemental structure of the ceiling
materials using Ion Beam Analysis facility. 0.05 kg of the samples were combusted in a controlled fire chamber
and the gasses emitted; CO, SO2, NO, and volatile organic compounds (VOC) were identified using four gas
analyzers. Elements were detected in total and data collected from the experiment were analyzed. Results
showed that Nigerian made PVC has the highest total noxious gas among the three samples with value of
3732.5 ppm while layered composite PVC has the lowest among the PVCs with the value of 1477.5 ppm. The
elemental make-ups of the samples influence their emission characteristics. The study established that PVC
samples were noxious in terms of their emission characteristics due to the effects of their elemental basis.
