Ulsan Bay sediments (Onsan refineries)
Ulsan, East Sea, Corée du Sud
Sediments
- Type
- Sediment
Sediments contaminated in Cu, Zn, Cd and Pb mainly by the Onsan non-ferrous refineries (Korea Zinc, LS Nikko), then by shipyards at the Taehwa River mouth. Three anthropogenic lead sources, ascribed to ores imported from Australia, Peru and the United States: 207Pb/206Pb of about 0.905 (S1), 0.878 (S2) and 0.840 (S3). Indicative coordinates.
207Pb/206Pb isotope ratio, no unit Values of the same system
Standard : NIST SRM 981
