Jiang 2026 - Organotins in Hong Kong seafood

Jiang and colleagues assessed organotin compounds in Hong Kong seafood after the 2017 local ban on organotin antifouling systems on vessel hulls. The extracted source is a ScienceDirect article-preview printout, but the abstract and snippets report direct occurrence and exposure numbers for 23 marine species collected in 2023. The analytes are organotin compounds, including TBT and TPT; they are tin-organic species and should not be pooled as total tin.

Key numbers

The abstract reports the following organotin occurrence and exposure findings:

The abstract states that total organotins exposure via seafood consumption was generally within the source’s safety threshold of 1 for general adults, while high consumption of fish species with high TPT concentration, including Gerres septemfasciatus and Johnius taiwanensis, could increase health risk.

Methods (brief)

The preview states that 23 marine species from Hong Kong waters were collected in 2023 across molluscs, crustaceans, and fishes. It names six organotin standards used in the study: MBT, DBT, TBT, MPT, DPT, and TPT; di-n-heptyltin dichloride was used as a surrogate standard, and ethyltri-n-propyltin was also named in the standards snippet. The extracted text does not include the full analytical method, limits of detection, species-by-species tables, or sample counts by species. Concentrations in the abstract are reported in ng/g ww.

Implications

This source contributes post-ban Hong Kong seafood organotin occurrence and exposure context across fish, molluscs, and crustaceans. It is especially useful because it separates phenyltins and TPT dominance from total organotin burden; downstream routing should keep organotin species distinct from inorganic tin or total Sn. The page is evidence-tier B because the provided file is an article-preview printout and not the full article tables.

Verification notes

• PDF text extracted with pdftotext -layout; the file is a ScienceDirect article-preview printout. Title, DOI, abstract, highlights, introduction, section snippets, and conclusion snippets were readable; full tables were not present.
• DOI 10.1016/j.marpolbul.2026.119345, raw handle MFK_health-risks-of-exposure-to-organotin-compounds-vi, and cite-key checks found no existing source page before creation.
• All numeric values in ## Key numbers were checked against the extracted abstract/highlights/snippets. No species table was available in the extracted text, and no table-only values were invented.
• Units are preserved as ng/g ww and ng/kg bw/day; no conversion was performed.
• Speciation: organotin species are reported as MBT, DBT, TBT, MPT, DPT, and TPT. Frontmatter uses Sn for element-level routing following existing wiki convention, but this page explicitly documents that organotins must not be treated as inorganic tin or total Sn.
• Brand firewall: no brand-level seafood values were reported.
• Frontmatter product and ingredient slugs were checked against docs/gpt-collaboration/taxonomy-snapshot.md; no new slug was invented.
