A total of 109 samples of urban, peri-urban and rural soils were analyzed with X-ray fluorescence to determine most of the elemental concentrations analyzed. The C and S analyses were performed with the high-temperature combustion method, and a MERCUR mercury analyzer was used for Hg. The study shows that the distribution patterns for most major elements and some trace elements are controlled by the lithologic substrate. This study identified areas with metals and metalloids in high concentrations, which are a risk to the environment and health according to established international regulations. Some of these components correspond to Cu (2500\u00a0ppm), Mo (26,5\u00a0ppm), As (134,6\u00a0ppm), Cr (206.6\u00a0ppm), Hg (0.2\u00a0ppm), Ni (26.4\u00a0ppm), Pb (61.7\u00a0ppm), V (227,2\u00a0ppm) and Zn (180.3\u00a0ppm). Through an elementary association analysis, most of these elements resulted from extractive activities of Cu, metal alloys and oil combustion. It was also possible to trace the use of fertilizers and pesticides in agricultural soils, as well as the combustion of oil related to vehicles in the study area. This information is relevant to implement environmental management strategies to control possible exposure to toxic compounds to human health.<\/jats:p>","DOI":"10.1007\/s10653-021-01098-4","type":"journal-article","created":{"date-parts":[[2021,10,10]],"date-time":"2021-10-10T16:09:44Z","timestamp":1633882184000},"page":"3173-3189","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["The environmental geochemical baseline, background and sources of metal and metalloids present in urban, peri-urban and rural soils in the O\u00b4Higgins region, Chile"],"prefix":"10.1007","volume":"44","author":[{"given":"Ana","family":"Vald\u00e9s Dur\u00e1n","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillermo","family":"Aliaga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katja","family":"Deckart","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cyrus","family":"Karas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dante","family":"C\u00e1ceres","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriana","family":"Nario","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,10,9]]},"reference":[{"key":"1098_CR1","doi-asserted-by":"publisher","first-page":"1615","DOI":"10.1081\/CSS-120038558","volume":"35","author":"I Ahumada","year":"2004","unstructured":"Ahumada, I., Escudero, P., Ascar, L., Mendoza, J., & Richter, P.
