Abstract
This study delves into the multifaceted impacts of ocean acidification on Paphia undulata shells, elucidating the interconnected consequences of increased carbon dioxide (CO2) emissions. As a major driver of climate change, CO2 is absorbed by the ocean, inducing a chemical transformation termed ocean acidification. The altered seawater chemistry affects the alkalinity of the ocean and leads to a decline in the concentration of calcium carbonate in Paphia undulata shell powder, impacting the calcination process in bivalves. SEM analysis reveals a reduction in the size of Paphia undulata shell powder. GCMS analysis identifies pharmacologically important compounds, such as thymol-TMS and demelcolcine, in the shell biomineral. XRD analysis demonstrates changes in crystallinity due to ocean acidification. Additionally, the biomedical properties of powdered Paphia undulata shells offer valuable insights for developing alternative antiviral drugs. The comprehensive findings underscore the far-reaching consequences of ocean acidification on the thickness, strength and integrity of economically and ecologically vital Paphia undulata shells, emphasizing the urgency of addressing this environmental challenge. Embracing sustainable practices, adopting circular economy models and minimizing carbon emissions are emphasized as crucial steps in averting further ocean acidification and preserving marine environments.
