This study assessed the chemical composition, antioxidant capacity, and bioaccumulation of heavy metals (Cd, Pb, Ni) in Boletus edulis, Imleria badia, and Leccinum scabrum collected from two forested regions of north-western Poland differing in anthropogenic influence and soil characteristics. The analysis encompassed structural polysaccharides (\u03b2- and \u03b1-glucans, chitin), carotenoids, L-ascorbic acid, phenolic and organic acids. B. edulis exhibited the highest \u03b2-glucan and lycopene contents, but also the greatest cadmium accumulation. I. badia was distinguished by elevated ascorbic and citric acid levels and the strongest DPPH radical scavenging activity, while L. scabrum showed the highest ABTS and FRAP antioxidant capacities and accumulated quinic acid and catechin. Principal component analysis indicated strong correlations between antioxidant activity and phenolic acids, while cadmium levels were inversely associated with antioxidant potential and positively correlated with chitin. Although all metal concentrations remained within EU food safety limits, B. edulis showed consistent cadmium bioaccumulation. From a practical perspective, the results highlight the importance of species selection and sourcing location when considering wild mushrooms for consumption or processing, particularly in the context of nutritional value and contaminant load. Importantly, regular or excessive consumption of B. edulis may result in exceeding the tolerable weekly intake (TWI) levels for cadmium and nickel, which warrants particular attention from a food safety perspective. These findings underscore the influence of species-specific traits and environmental conditions on mushroom biochemical profiles and support their potential as functional foods, provided that metal contents are adequately monitored.<\/jats:p>","DOI":"10.3390\/molecules30153277","type":"journal-article","created":{"date-parts":[[2025,8,5]],"date-time":"2025-08-05T13:44:32Z","timestamp":1754401472000},"page":"3277","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Bioactive Compounds and Antioxidant Activity of Boletus edulis, Imleria badia, Leccinum scabrum in the Context of Environmental Conditions and Heavy Metals Bioaccumulation"],"prefix":"10.3390","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8303-9044","authenticated-orcid":false,"given":"Zofia","family":"Sotek","sequence":"first","affiliation":[{"name":"Institute of Marine and Environmental Sciences, University of Szczecin, Adama Mickiewicza 16 Street, 70-383 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5536-4114","authenticated-orcid":false,"given":"Katarzyna","family":"Malinowska","sequence":"additional","affiliation":[{"name":"Department of Bioengineering, West Pomeranian University of Technology in Szczecin, S\u0142owackiego 17 Street, 71-434 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9367-9275","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Stasi\u0144ska","sequence":"additional","affiliation":[{"name":"Institute of Marine and Environmental Sciences, University of Szczecin, Adama Mickiewicza 16 Street, 70-383 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3606-1927","authenticated-orcid":false,"given":"Ireneusz","family":"Ochmian","sequence":"additional","affiliation":[{"name":"Department of Horticulture, West Pomeranian University of Technology in Szczecin, S\u0142owackiego 17 Street, 71-434 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"95","DOI":"10.1615\/IntJMedMushr.v14.i2.10","article-title":"The role of culinary-medicinal mushrooms on human welfare with a pyramid model for human health","volume":"14","author":"Chang","year":"2012","journal-title":"Int.
