A new sensitive determination method of domoic acid based on the chemiluminescent reaction of tris(2,2′-bipyridine)ruthenium(III) has been developed. The method exhibited good reproducibility. The relative standard deviation of six replicate measurements was 1.6% for 10 ng ml<sup>-1</sup>. A calibration graph, based on a standard domoic acid solution, was linear over the range of 1 - 500 ng ml<sup>-1</sup> (coefficient of correlation, <i>r</i><sup>2</sup> = 0.9995) and the detection limit was 8 pg (signal-to-noise ratio = 3) without any preconcentration and derivatization steps. This new method was successfully applied to a real sample of blue mussels spiked with 2 µg g<sup>-1</sup> domoic acid.
