Abstract
Aim: There is increasing ecological and global health concern associated with environmental contamination by heavy metals. The main objective of the study was to analyze the spatial distribution of heavy metals in soil, water and anurans (frogs and toads) from four sites in Al-Hayr, Riyadh city.
Methodology: Seven heavy metals (Cu, Cr, Cd, Ni, Zn, Pb and Mn), were estimated to determine the concentration levels in Heavy metals were assayed soil, water and anuran (Cu, Cr, Cd, Ni, Zn, Pb and Mn) in: liver tissues obtained from Al-Hayr region and arranged in descending order. Relative accumulation indices (RAI) were used to determine the bio-accumulation rate in anuran liver tissues.
Results: Soil and water results showed that no values appeared to be unusual, while two types of anurans (frogs and toads) were found having same RAI distribution and showed the same descending order. All values were statistically insignificant.
Interpretation: The perusal of data revealed that Al-Hayr was considered a non polluted area.
