Determination of Toxic Elements in Botanical Dietary Supplement Ingredient Reference Materials.

ABSTRACT:

Background

The National Institute of Standards and Technology (NIST) has produced over 40 botanical dietary supplement Standard Reference Materials (SRMs) and reference materials (RMs) with values assigned for chemical markers and/or active compounds. Although environmental accumulation or inadvertent introduction of toxic elements (arsenic, cadmium, lead, and mercury) is a potential source of exposure in botanical dietary supplement products, the majority of the dietary supplement SRMs/RMs do not have values assigned for the four major toxic elements.

Objective

To determine As, Cd, Pb, and Hg content in the current inventory of NIST botanical dietary supplement SRMs/RMs.

Methods

Fifteen SRMs/RMs suites of plant part, extract, and finished products (i.e., solid oral d
