Chemometric techniques for distribution and source identification of PAHs in selected coastal zones of Malaysia

Key Points

• Distribution patterns of polycyclic aromatic hydrocarbons were analyzed using advanced chemometric techniques, revealing significant insights.
• Key metrics indicated variations in pollution levels across selected coastal zones, emphasizing the area's vulnerability.
• Assessment using chemometric analysis across multiple sample sites showed distinct sources contributing to PAH levels in these environments.
• Highlighting the pressing need for further monitoring, this study underscores the potential risks posed by PAH contamination in coastal ecosystems.
