Additional Provisional Elemental Values for LKSD‐1, LKSD‐2, LKSD‐3, LKSD‐4, STSD‐1, STSD‐2, STSD‐3 and STSD‐4

Provisional values related to element concentration derived from partial extractions as well as some additional total concentration data are reported for eight CCRMP sediment reference materials. These values are intended to supplement previously published data for these samples. The partial extractions for which data are reported include dilute HNO 3 ‐ dilute HCl, concentrated HNO 3 ‐concentrated HCl and concentrated HNO 3 ‐concentrated HClO 4 .
