- Bioaccumulation
- T6: Food-Web Structure and Biomagnification Paradox. Biomagnification is often described as a strict up-the-chain multiplication, but real food webs are complex: omnivory, ontogenetic (age-based) dietary shifts, detrital pathways, and variable trophic transfer efficiencies all modify the simple trophic-level multiplication, as Kelly, Ikonomou, Blair, Morin, and Gobas (2007) demonstrated in their Science analysis of food-web–specific biomagnification of persistent organic pollutants across an Arctic marine food web.
This sourceDemonstrates that biomagnification and trophic magnification depend on food-web structure, with the headline result that K_OA-driven biomagnification reaches air-breathing animals; analyzed in an Arctic marine food web
Supported in partVerified against the publisher's abstract
The abstract shows biomagnification is food-web–specific: chemicals that do not biomagnify in aquatic webs do so in webs with air-breathing animals; the listed mechanisms are not stated.
“poorly metabolizable, moderately hydrophobic substances with a K OW between 100 and 100,000, which do not biomagnify (that is, increase in chemical concentration in organisms with increasing trophic level) in aquatic food webs, can biomagnify to a high degree in food webs containing air-breathing animals (including humans) because of their high octanol-air partition coefficient ( K OA ) and corresponding low rate of …”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
