INTRODUCTION 9 This situation requires the development of better methods for managing the increased quantity and the quality of the data. For the former -- the recording, storage, and digesting of the data -- computer techniques are available and are becoming more common.

INTRODUCTION 11 solutions, the majority of materials discussed are "compositional" or matrix reference materials. Such materials are based on "natural" substances (e.g., seawater, sediments, or biological materials such as phytoplankton)

12 CHEMICAL REFERENCE MATERIALS als. Furthermore, reference materials are costly to produce -- particularly if they are certified for a number of constituents -- and it has not always been clear that this cost is repaid with significant added value.

INTRODUCTION 13 provided a basis for future committee discussions during the preparation of this report. However, the costs of developing new certified reference materials are substantial and new projects should not be entered into lightly.

14 CHEMICAL REFERENCE MATERIALS analytes, would represent stable homogeneous samples for a far wider range of additional constituents than is currently available. The committee recommends that these reference materials be investigated further by the scientific community to ascertain their usefulness for a wide range of constituents such as trace metals, organic compounds, and radioisotopes.
