phenolic antioxidants (SPAs) are widely used in foodstuffs,
cosmetics, plastics, and rubber products. Little is known about their
spatiotemporal distribution in the marine environment. In this study,
a total of 144 surface sediments and three sediment cores were collected
from the coastal areas of northern China to determine the spatial
and vertical distributions of SPAs. For surface sediments, the total
concentrations of five SPAs and their four metabolites (∑9SPAs) ranged from 133 to 4800 (mean: 588) ng/g dry weight
(dw). The ∑9SPAs in surface sediments showed a decrease
trend with the distance from the coast to the open sea. For sediment
core samples, the ∑9SPAs in the inner-shelf mud
(core-1 and core-3) showed a slight increase trend from the bottom
to upper layers, whereas that in the central-shelf mud (core-2) did
not. The principal component analysis suggests that the composition
profiles of SPAs in both surface sediment and sediment core samples
were similar, while the sediments close to the coast were obviously
affected by the human activities. This is the first study to report
the spatial and vertical distributions of SPAs and their metabolites
in sediments from the coastal marine environment.
