Trace metals composition of the sediments from the Birmingham Canal Navigations

The fast urbanization is causing pollution of the water environment with trace metals (TMs) and these TMs are readily absorbed in sediments since they are not very soluble in water. With an emphasis on concentration levels, dispersion patterns, and possible environmental ramifications, this study examines the trace metal content of sediments from the Birmingham Canal Navigations (BCN). Using X-ray fluorescence (XRF) spectroscopy, 20 sediment samples were taken at 100-meter intervals along the canal and examined for heavy metals such as arsenic (As), cadmium (Cd), chromium (Cr), mercury (Hg), lead (Pb), and selenium (Se). Lead (Pb) had the highest concentration, surpassing soil guideline values (SGVs) for commercial, residential, and allotment exposures, according to the results, while selenium (Se) had the lowest concentration. Pb and Cr posed the greatest ecological and health threats, according to statistical studies such as ANOVA and Pearson correlation, which revealed notable variation in metal concentrations among the sampling sites. According to the findings, urbanization and industry are the main causes of sediment contamination. To mitigate these concerns, it is advised to implement land-use management techniques to reduce the buildup of trace metals, increase monitoring, and dredge more frequently. This study emphasizes how crucial canal sediment management is to safeguarding aquatic ecosystems and public health.
