Impact of Volcanic-Derived Polycyclic Aromatic Hydrocarbons on Apoptosis, Necrosis and p53 Expression in Hawaiian Green Turtle Lung Cells

Abstract

Polycyclic aromatic hydrocarbons (PAHs) are common environmental pollutants that are known for their cytotoxic, mutagenic, and carcinogenic effects on human health. However, compared to their known effects on human health, their impact on marine species remains relatively unexplored. In this study, we investigate the cellular toxicity of volcanic-derived PAHs on green turtle (Chelonia mydas) lung cells, particularly under the broader concerns of the recent Kīlauea volcanic eruption on Hawaii’s Big Island. In the experiment, isolated green turtle lung cells are treated with various concentrations of PAHs and assessed by cell viability, apoptosis, and p53 expression. Under analysis and discussion, the literature review highlights the potential adverse effect of volcanic pollutants to marine life and also underscores the need for conservation strategies to protect the green turtle and other vulnerable species.
