A direct current plasma spectrometer system has been used to determine specific trace elements in samples collected during several marine monitoring surveys. The data is currently being used to assess the impact on the environment of North Sea oil exploitation. The trace elements are routinely monitored in sediment and shellfish extracts and in oil terminal water effluents. The techniques used in conjunction with the d.c. plasma system are evaluated. Stray light and spectral interference problems from calcium and magnesium emissions are identified. Compensation for the interferences using simple linear corrections are described. Analysis of standard reference materials indicates that the direct current plasma system yields results comparable to other analytical techniques. © 1983.
