Polycyclic aromatic hydrocarbons (PAHs) in mangrove ecosystems: A review

Area of Science:

• Environmental Science
• Ecotoxicology
• Marine Biology

Background:

• Polycyclic aromatic hydrocarbons (PAHs) are priority pollutants with mutagenic and carcinogenic properties.
• Their hydrophobicity and stability lead to environmental persistence and long-range transport.
• PAHs pose toxicological risks and bioaccumulate in food webs, impacting ecosystems and human health.

Purpose of the Study:

• To provide a comprehensive review of existing knowledge on PAHs in mangrove ecosystems.
• To elucidate the dynamics of PAH transfer, accumulation, and degradation within these critical environments.
• To identify knowledge gaps and suggest future research directions for understanding PAH behavior in mangroves.

Main Methods:

• Literature review synthesizing studies on PAHs in mangrove ecosystems.
• Analysis of data concerning PAH transfer, accumulation, and degradation processes.
• Identification of research trends and areas requiring further investigation.

Main Results:

• Significant research exists on PAH accumulation and degradation in soils, but mangrove-specific dynamics are less understood.
• PAHs are persistent environmental pollutants with known toxicological effects and bioaccumulation potential.
• Mangrove ecosystems represent a unique environment for studying PAH fate and transport.

Conclusions:

• A comprehensive understanding of PAH dynamics in mangrove ecosystems is crucial due to their environmental and health concerns.
• Further research is needed to fully comprehend PAH transfer, accumulation, and degradation in these vital habitats.
• This review highlights the current state of knowledge and outlines perspectives for future scientific inquiry.
