Trace metalloid and inorganic selenium concentrations in sediment pore water

URI http://vocab.nerc.ac.uk/collection/P02/current/MDPW/4/
Within Vocab SeaDataNet Parameter Discovery Vocabulary
Alternative Labels Metoid_SedPW
Definition Concentration parameters for trace metalloid elements and inorganic selenium species in water occupying the space between sediment grains. Trace metalloids are considered as B, Ge, As, Sb, Te, and Po (but not Si which is classed separately because of its major role in environmental chemistry).
