# SSD library — wishlist (want, but not retrievable)

*Tracked per the library goal. Correct DOIs (from Crossref) are noted so a retry / institutional pull is easy.

## Three critique papers — ✓ ALL RETRIEVED 2026-06-14 (operator Taildrop); earlier OA sweep (2026-06-13) had failed
*Lawful-route sweep on 2026-06-13 (publisher OA, government/EPA, university repositories incl. White Rose &
WUR, RUCforsk, VIMS author self-archive, core.ac.uk, Semantic Scholar, OpenAlex/Unpaywall, Wayback). All three
are flagged **`oa_status: closed`** by OpenAlex/Unpaywall with **no open-access PDF anywhere**. Per CLAUDE.md
they were **NOT** taken from any shadow library. Citation + abstract held below for the essay; flip to
RETRIEVED only via lawful institutional access (T&F / Wiley / Oxford-ETC subscription).*

  (doi 10.1.1.334.2212) has no live PDF. *Abstract:* lognormal fit rejected for **15 of 30** datasets; a
  **bootstrap** (distribution-free) gave accurate HCp; adequate HC5 needed **15–55 species (median 30)** —
  more than regulators then required. *Key sample-size / distribution-type critique — HIGH PRIORITY.*

  composition** of the assemblage significantly shifts the hazard estimate, whereas **habitat and geography do
  not**; guideline-recommended species gave SSDs no different from non-recommended ones; recommends a **safety
  factor ≥5 on the median HC5** for repeated/continuous exposure. *Test-species-selection / selection-bias

  (`forskning.ruc.dk/.../83ebd170-…`) but is **metadata-only — no attached file**; T&F paywalled. *Abstract:*
  SSDs are "typically based on **haphazard collections of species endpoints**"; adjusting them toward realistic
  trophic structure shifts the threshold "in a direction and extent that is **not predictable**"; the "uses all
  available data" claim is false — common applications "**only use a small fraction of the species data**."
  ***The single most important critical-appraisal paper.* HIGHEST PRIORITY** — needs T&F institutional access.

- **✓ RETRIEVED (2026-06-11) — Solomon et al. (1996)** atrazine ERA — the SETAC DOI served a wrong PDF, but the
  **Wiley DOI `10.1002/etc.5620150105`** fetched the correct 46-pp paper. Now in `papers/`. *(Lesson: when a
  pre-2010 SETAC/Allen-Press `10.1897` DOI mismatches, try the Wiley `10.1002/etc.5620…` alternate.)*

  any assumptions about the distribution," *Ecotoxicology* 10:25–34. DOI `10.1023/A:1008998405241` — "not
  found on Sci-Hub mirrors." *Non-parametric alternative.*
