Description
Summary:Seasonal variations and proximity to polluted sites, among other factors, play a vital role in soil composition. The impact of spatio-seasonal changes on bacterial and heavy metal content on and around the platinum mine tailings dam, Rustenburg, South Africa, was assessed. Tailings and topsoils collected during summer and winter were examined for bacterial abundance, physicochemical parameters and metal contents using standard methods. Data were analysed using ANOVA, correlation and cluster analyses. Bacteria counts were 2.5 × 105 to 1.0 × 106 and 3.5 × 105 to 7.8 × 105 CFU g−1 in summer and winter, respectively. Molecular identification revealed the presence of the bacterial species Paenibacillus lautus and Stenotrophomonas maltophilia. Significant (p Cu > Cr was observed with significantly (p
