This editorial introduces eight studies on chromium release, toxicity and remediation. It provides a secondary overview of environmental pathways and treatment approaches; it reports no new sampling campaign or independent adsorption experiment.
Key numbers
The editorial’s summary of Pakade et al. (p1780) reports 89.7% removal for an iron-zinc biochar at pH 3.0. Its summary of Fall et al. (p1780) reports an adsorption capacity of 91.7 mg/g for a magnetic carbon composite after 240 minutes at 25 °C. These quantities belong to different underlying studies and must not be compared as equivalent treatment outcomes.
The editorial’s summary of Ndiaye et al. (p1780), a Senegal fish study, reports approximate first-campaign means of 11.1 µg/g for Pagellus bellottii and 40.6 µg/g for Lagocephalus laevigatus, attributed to Cr(VI). The editorial does not establish measurement basis, sample counts or species-preservation validation; the primary study is needed before reuse as food-occurrence evidence.
Methods (brief)
Two-page editorial synthesis of the accompanying special issue, covering industrial sources, natural weathering, soil transport, adsorption, chemical reduction and aquatic contamination. No original analytical protocol or systematic search is presented.
Evidence fitness
Useful as an attributed overview and as a route to primary remediation and environmental studies. Secondary numbers remain linked to the study named in the editorial and do not form a new independent dataset.
Limitations
The editorial’s regulatory comparator is not verified from a primary instrument and is not adopted here. A cited crustal background concentration is also not a legal maximum. Its broad health statements do not establish dose-specific cancer or other individual risk estimates. Food, water, adsorbent and industrial-process measurements retain separate bases.
