Researchers measured extractable organohalogens like PCBs, DDTs, and chlordanes in Weddell seal blubber from 1980 to 1982. The dataset shows age-trend accumulation of compounds like EOBr and EOI, with known organic chlorine in EOCl increasing gradually but remaining below 1%. The data was collected by SCIOPS at Syowa Station in Antarctica.
Use Cases
- Analyze age-trend accumulation of extractable organobromine (EOBr) and organoiodine (EOI) in seal blubber.
- Compare concentrations of known pollutants like PCBs and DDTs against unidentified organic halogen compounds.
- Investigate the percent composition of known organic chlorine in EOCl relative to seal aging.
- Model the estimated concentration range (from pg/g to μg/g) of halogenated compounds across different species.
Strengths
- Data provides specific temporal coverage from 1980 to 1982.
- Includes measurements for multiple compound classes: PCBs, DDTs, chlordanes (CHLs), EOBr, and EOI.
Limitations
- Sample size and row count are unknown.
- Data is temporally stale, with the last update in 1982.
- Geographic coverage is limited to a single location: Syowa Station, Antarctica.
