New Zealand Food Safety has issued a public health warning urging people not to collect or consume shellfish along the Bay of Plenty coastline, from just

“Generally, the more algae there are in the water, the more toxic the shellfish get,” he said.

ABSTRACT Okadaic acid is a fatty acid polyether biotoxin that poses a significant threat to global human health. In this work, a type of heterogeneous microporous organic network films was synthesized using a surface-initiated polymerization method, which was employed to control the growth of microporous organic network onto the bromine-functionalized surface of a polymer film. The resulting microporous organic network films feature a porous structure, a strong hydrophobic surface, excellent chemical stability, a large specific surface area, and abundant adsorption sites. These films were then applied in film-based solid-phase extraction, and showed outstanding extraction performance for okadaic acid. Under optimized conditions, the film-based solid-phase extraction method was combined with high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) to establish a new analytical method with high sensitivity and efficiency. The developed method offers a wide linear range (2.0–1000.0 pg mL−1) with good linearity (r ≥ 0.9998), a low detection limit (0.5 pg mL−1), and high precision (RSDs ≤ 5.2%, n = 5). This method was further utilized for the determination of okadaic acid in seafood, successfully detecting trace levels of okadaic acid (5.4 and 13.9 pg mL−1) with satisfactory recoveries (85.4%–105.8%). The results indicate that the microporous organic network films hold great application potential in sample pretreatment, and provide a novel synthesis strategy for microporous organic network films.
