Organic contaminants detected in sediments from Geoscience Australia's marine survey S282 in the Arafura Sea. The dataset likely contains identified compounds such as fatty acid amides, antioxidants, and UV absorbers, along with their potential sources from sampling materials. The data was collected by the Australian Ocean Data Network.
Use Cases
- Identify contamination sources in geochemical sampling based on described compound profiles.
- Assess the impact of plastic bags and sunscreen on sediment samples based on the described contamination pathways.
- Distinguish anthropogenic hydrocarbons from natural seepage evidence based on the described branched alkane and alkyl cyclohexane series.
Strengths
- Description identifies specific contaminants (fatty acid amides, butylated hydroxytoluene, Irganox 1076, octabenzone, octyl methoxycinnamate).
- Description identifies specific contamination sources (two brands of plastic bags, sunscreen on hands).
- Description includes analysis of hydrocarbons (branched alkanes with quaternary carbon atoms, alkyl cyclohexanes) that could mimic petroleum.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
