Polycyclic aromatic hydrocarbons in rock oysters: a baseline study.
International Journal of Environmental Analytical Chemistry
|January 1, 1985
Summary
Polycyclic aromatic hydrocarbons (PAHs) in oysters from Mermaid Sound, Australia, were analyzed. Levels were generally low, with higher concentrations near the Port of Dampier, potentially from shipping activities.
Area of Science:
- Marine biology
- Environmental chemistry
- Ecotoxicology
Background:
- Mermaid Sound is a significant marine ecosystem in North-Western Australia.
- Assessing polycyclic aromatic hydrocarbons (PAHs) in marine bivalves is crucial for environmental monitoring.
- Oysters are effective bioindicators of marine pollution.
Purpose of the Study:
- To quantify polycyclic aromatic hydrocarbon (PAH) levels in coral-rock oysters from Mermaid Sound.
- To investigate the distribution and potential sources of PAHs in the study area.
- To assess the impact of port activities on marine pollution.
Main Methods:
- Oysters were collected from six sites in Mermaid Sound.
- Sample analysis involved digestion, solvent extraction, and High-Performance Liquid Chromatography with Ultraviolet Fluorescence detection (HPLC-UVF) and Gas Chromatography-Mass Spectrometry (GC-MS).
Main Results:
- Two- and three-ring aromatic hydrocarbon levels ranged from very low to low across sites.
- Higher PAH concentrations were observed at sites within Mermaid Sound closer to the town and port.
- PAHs with four or more rings were generally below detection limits.
- Parent PAHs constituted a larger proportion of the total PAH assemblage near the port.
Conclusions:
- PAH levels in oysters from Mermaid Sound are generally low.
- Port activities, including shipping and vessel operations, are likely contributors to observed PAH levels.
- The presence of parent PAHs suggests contributions from high-temperature processed materials.
