Unexpected High Blood Lead Levels in a Remote Indigenous Community in the Northeastern Peruvian Amazon

Recent studies suggest that Pb-based ammunition could be an important route of Pb exposure for Indigenous Peoples in tropical rainforests. We analyzed blood lead levels (BLL) and isotopic signatures in 111 humans, 97 wild animals, 81 fish, and potential environmental Pb sources in an Indigenous comm...

We analyzed blood lead levels (BLL) and isotopic signatures in 111 humans, 97 wild animals, 81 fish, and potential environmental Pb sources in an Indigenous community in the remote and well-preserved Peruvian Amazon with no history of industrial activity. Median BLL was 11.74 μg dL -1, with BLL ≥ 5 µg dL -1 in 95.8% children <12-yo and 94.5% adults. Pb concentrations in wild animals were 7.00 ± 22.40 mg kg -1 DW in liver, 0.06 ± 0.09 mg kg -1 DW in fish muscle tissues, 17.1 ± 10.8 mg kg -1 in soils and 3.4-3.8 mg L -1 in the main river, although 0.43-0.53 mg L -1 were the Pb levels in decanted water used for drinking and cooking. The similarity of isotopic signatures (207/206 Pb and 208/206 Pb) shows that the main Pb sources for humans are river waters (97.6%) and Pb-based ammunition (78.7%). Fish and wildlife act as Pb transporters from water, and wildlife act as Pb transporter from ammunition. Evidence of high human BLL in a remote, non-industrialized Amazonian area demonstrates the urgency of designing regional policies that include health prevention measures, focused on drinking water filtration systems and the use of non-toxic, Pb-free ammunitions. 22025-01-0120252025-01-01Articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/322089https://dx.doi.org/urn:doi:10.3390/toxics13100826reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengInstituto de Salud Carlos III https://doi.org/10.13039/501100004587 CNPq-400800/2019-5Agencia Estatal de Investigación https://doi.org/10.13039/501100011033 RYC-2016-21366Agencia Estatal de Investigación https://doi.org/10.13039/501100011033 RTI2018-095949-B-I00Agencia Estatal de Investigación https://doi.org/10.13039/501100011033 PID2022-141463OB-I00Ministerio de Economía y Competitividad https://doi.org/10.13039/501100003329 MDM-2015-0552Ministerio de Ciencia e Innovación https://doi.org/10.13039/501100004837 CEX2019-000940-M"la Caixa" Foundation https://doi.org/10.13039/100010434 LCF/BQ/DI24/12070014open accesshttp://purl.org/coar/access_right/c_abf2Aquest document està subjecte a una llicència d'ús Creative Commons.
