Summary

Five-stage sequential extractions were performed on ultramafic soil from Bosque Susua and Guanica Dry Forest, stream sediment from Rios Loco and Yauco, and nearshore sediment from Guanica Bay in southwest Puerto Rico. Sequential extractions showed partitioning of geologically enriched metals and other elements among five phases: 1) adsorbed and calcium-bound, 2) iron-, manganese-oxyhydroxide-bound, 3) crystalline iron-oxide-bound, 4) sulfide-bound, and 5) residual. Total element contents are also reported. Soil and sediment were collected between June 19, 2017, and March 27, 2018.

Purpose

Partitioning of potentially toxic metals was investigated in serpentinite other types of soils in Rio Loco and adjacent watersheds to determine potential metal mobility, bioavailability, and environmental health risk from geologically enriched metals.
