Supplementary Figure 1. LC-MS/MS chromatograms for BMAA, DAB
and AEG standards (a, b), extracts of phytoplankton (c, d) and
zooplankton (e, f) using HILIC direct analysis (a, c, e) and precolumn
AQC-derivatization method (b, d, f).
Supplementary Figure 2. Percent of diatom and dinoflagellate
(%), and cell density (cell m-3) in the phytoplankton
net samples collected in (a) January, (b) March, (c) June, and (d)
September, from the Jiaozhou Bay.
Supplementary Figure 3. Average concentrations of BMAA in
phytoplankton and zooplankton samples collected from 12 sampling
stations in Jiaozhou Bay during four seasons.
Supplementary Figure 4. The highest trophic magnification
factor (TMF) from phytoplankton to zooplankton at different sampling
stations during four seasons. The sampling station C1 has not been given
TMF value because BMAA was not detected in zooplankton in January and
not detected in phytoplankton in other seasons.
