A Note on Remobilization of Heavy Metals from Beachrocks to Costal Water as Consequence of Sea Water Acidification

摘要

Sediments are considered as reservoirs of metals, many studies have shown the ability of beachrocks "rocks that form on the beaches" for trapping metals during the process of formation and cementation. The beachrocks are chemically composed primarily of calcium carbonate "CaCO3" which easily allows the weathering of rocks and releasing metals trapped before "washing" as a result of acidity. In this note we highlight the probable remobilization of metals form beachroks to coastal waters by leaching due to rising acidity of seawater.
