Item type:Publication, Heavy metal contents in soils and native flora inventory at mining environmental liabilities in the Peruvian Andes(Elsevier, 2020-12-16)Inadequate waste management in Mining Environmental Liabilities (MEL) represents a risk for the environment and human health and generates social problems. The aim of this article is twofold: i) to evaluate the environmental quality of soils from a geo-ecological perspective; and ii) to inventory native flora around two MEL in the Hualgayoc district in the Peruvian Andes. Soil samples collected for topsoil (upper 30 cm; i.e., soil arable layer) and subsoil (30–60 cm) were classified as Gleyic Cambisols and showed extremely acid pH (3.50–4.19 in site #1 and 2.74–4.02 in site #2). The mineralogical composition of soils is dominated by illite, kaolinite, quartz, and jarosite. The concentrations of six potentially toxic elements (Pb, Zn, As, Cu, Ag, and Cd) were determined. High concentrations of Pb (4683 mg kg−1), Zn (724.2 mg kg−1), Cu (511.6 mg kg−1), Ag (33.4 mg kg−1), and As (3611 mg kg−1) exceeded the maximum permissible limits for agricultural soils according to Peruvian and Canadian regulations. Applied geochemical indexes classified some of the soils as extremely polluted and therefore the studied MEL represent a very high ecological risk. Twenty-two species of native flora belonging to 12 family species were inventoried in such contaminated sites thus having the potential to be used for phytoremediation purposes. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Continuity and change in the cult of the dead: Shaping kin formation in the Peruvian Andes (A.D. 1000–1600)(Taylor and Francis Ltd., 2024-01-01)This paper presents the results of archaeological investigations within funerary contexts at the site of Marcajirca (a.d. 1000–1600) in the north-central highlands of Peru. The results suggest the existence of various population groups, or ayllu members, that were buried at this site. Two contemporary types of tombs are predominant, funerary caves and chullpas, along with two belowground tombs, which are atypical in the region. Bioarchaeological analyses indicate that all the tombs were collective and that the remains were manipulated over time. The evidence from Marcajirca points to important changes in funerary patterns with respect to the previous period, including tombs being incorporated into residential places and, later in time, tombs as created, extra, private spaces by enclosing the chullpas within patios where rituals such as burning of offerings were practiced. The results are discussed within the context of the cult of the dead and the formation of ayllus. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Resource Booms and Entrenched Gender Roles in the Andes(Wiley, 2025-11-01)This paper examines the effects of mining booms on local labor markets in contexts where traditional gender roles limit women's participation. Results show that job creation is primarily driven by increased male employment in mining, with spillovers into construction and local services. Female employment responses are mixed, while some women gain access to these jobs, others shift toward unpaid domestic work. The expansion of mining appears to benefit men and unmarried women, while married women and those with caregiving responsibilities face reduced opportunities. Women are also more affected by heterogeneity in age and education. The findings underscore the role of the care economy and gender dynamics in shaping labor market outcomes during resource booms.1
