Abstract: A comprehensive analysis of heavy metals contamination was carried out in the marble building materials collected from di erent stores in Riyadh, Saudi Arabia, in which is subject to rapid construction development. In Riyadh, it has been observed environmental issues due to heavy metal pollution from new construction projects of underground metro as well as other new infrastructural developments. Therefore, it is very important to carry out an investigation of presence of heavy metals in marble materials as major unit of construction building materials. The bene t of full statistical evaluation was conducted to represent relationship models of the contents of heavy metals (Cr, Cd, Pb, Ga, and U)in marbles used in Saudi building. Four di erent methods of matrix correlations were used to obtained full spectra of relationship between studied heavy metals and other elements. Normality tests were conducted to help the statistical performance to treat the results as parametric. Moreover, Shewhart con dence limit tests were also applied to the reported data of each heavy metals to tell us the sample out of con dence limits. Lucky, all the statistical tests were within good agreement with critical values. The obtained data were compared with the value of heavy metals in upper earth crust reported by Muller. Geo-chemical indexes calculations were performed using geochemical hazard index, background enrichment index and other useful indexes. The values of hazard indexes were compared with tabulated or recommended values. The present study was found that marbles did not possess any signi cant hazard in term of heavy metals to the residents of Riyadh.
