摘要：
The concept of traceability implies that measurement data are linked to stated references through an unbroken chain of comparisons, all with stated uncertainties. This paper discusses how traceability can be conceived in the context of environmental measurements, in particular the various elements of the traceability chain (e.g., Sl units, documented standards, reference materials) to which chemical environmental data may be linked.
