TM93-08 New Inorganic Tissue Method

The Methods Research and Development Program recently completed development work on a method for analysis of trace metals in tissue. The method was tested and approved on an interim basis for the following tissues: fish liver, corbicula, bovine liver, oyster tissue, and peach leaves. The fish liver and corbicula homogenates were prepared at the NWQL, while the bovine liver, oyster tissue and peach leaves standard reference materials were obtained from the National Institute of Standards and Technology. The method was developed for the NAWQA Program Occurrence and Distribution Phase of sampling but can be utilized by other District projects. A number of questions concerning the method have surfaced over the last few months. The purpose of this tech memo is to clarify those questions and let WRD employees know how to request and use this method.
