Abstract Seston samples were collected at 42 surface stations located in the Quoddy Region, New Brunswick, Canada. In an attempt to separate ecologically important components, the seston samples were divided into two size fractions: 20 to 64 μm and 0.7 to 20 μm. Particulate organic carbon, particulate aluminum, chlorophyll a, particulate cadmium, and particulate lead concentrations were determined for both size fractions. Cadmium was found to be associated almost entirely with the organic detrital component of the seston, for both size fractions. In contrast, lead was associated with several seston components. For the 20 to 64 μm size fraction, lead was partitioned between the organic detrital and suspended clay aggregate components of the seston. Within the 0.7 to 20 μm fraction, lead was partitioned, in descending order of importance, between the organic detrital, suspended clay aggregate, and phytoplankton components. These partitioning characteristics of the two metals were used to predict accumulation trends of cadmium and lead in the calanoid copepod species which form the primary consumer level of the marine food web of the Quoddy Region.
