Hydrocarbons Associated with Suspended Particulate Matter in San Francisco Bay Waters,

Abstract

Suspended sediments were obtained at seven stations in San Francisco Bay during the summer of 1974 using a double settling tube device termed the 'biosampler.' One tube of the device passively collected suspended sediments which settled from ambient waters at the sampling sites. The top of the second tube contained bay mussels (Mytilus edulis) as biological agents for the active entrapment and deposition of suspended particulates occurring in the water. Presence of the mussels in the sampler was, in most cases, indispensable for collection of sufficient amounts of material for analysis over one-week sampling periods. A thin-layer chromatographic method was employed for analysis of total alkane and total aromatic hydrocarbons in recovered sediments. The sediments were found to contain 190-6188 ppm dry weight of total hydrocarbons, with alkane-aromatic ratios varying from 1.1 to 5.1.
