Linear regressions with 2019 data for phycotoxins in oysters versus phycotoxins in solid phase adsorption toxin tracking devices (SPATT), particulate organic matter (POM, >1 μm), and whole water samples.

|---|---|---|---|
| No lag | SPATT | −0.02 | 0.1 |

| POM | – | 0.3 | |

| Whole water | −0.02 | 0.6 | |
| (p = 0.8, n = 40) | (p < 0.0001, n = 40) | ||
| Two-week lag | SPATT | −0.02 | 0.1 |

The R2 is reported with the p-value and sample size. Significant linear regressions are bolded.
AZA1 = azaspiracid-1, DA = domoic acid.
Azaspiracid-1 (AZA1) was not detected in POM samples.
