Cáceres Ciencias de la Tierra PM2 tailings Human risk metalloids heavy metal The non-carcinogenic hazard index (HI) and the carcinogenic risk index (CRI) due to exposure to metal(loid)s were assessed in children and adults living adjacent to a beach contaminated with mine tailings. Chromium (Cr), nickel (Ni), cadmium (Cd), arsenic (As), zinc (Zn), copper (Cu), lead (Pb) and manganese (Mn) were determined in fine particulate matter (PM2.5) and sedimented dust (SD) in school and residential microenvironments. The HI in children was 13.8, 8.1, 5.4, 2.4, 2.3 and 1.8-times greater than the safety threshold (1.0) for Cr, As, Pb, Mn, Cu, and Cd, respectively; 84.1 % explained by dermal contact and 10.9 % by ingestion of SD. The CRI for Cr and As was 3.7 and 3.2 times above the acceptable risk (> 1 × 10-4), explained by the inhalation of PM2.5 and SD, respectively. In adults, the CRI for As and Cr was 46.0 and 2.8 times greater than 1 × 10-4; As risk is explained by dermal contact and inhalation of SD, and Cr by inhalation of PM2.5. This study reports a high risk of potential adverse health effects on children and adults due to exposure to these elements present in the particles and dust studied. 2021 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37072384021 https://www.redalyc.org/journal/370/37072384021/ https://www.redalyc.org/journal/370/37072384021/html/ https://www.redalyc.org/journal/370/37072384021/37072384021.epub https://www.redalyc.org/journal/370/37072384021/movil 10.20937/RICA.53830 en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Vol.37 |
