“…Firmicutes are normally more resistant to heavy metal contamination and heavy metal shifts in the soil, while Proteobacteria are more sensitive to these changes [3]. Considering this, the decrease in the relative abundance of classes belonging to Proteobacteria observed in this study could be related to climate-heavy metal interactions [71]. The class Acidobacteriia was also affected in the absence of invertebrates, increasing its relative abundance after exposure to increased air temperatures and drought and flood conditions.…”

“…Changes in DOC concentration can directly affect the reduction and oxidation of heavy metals in the soil, contributing to the transformation of these heavy metals into a more toxic form [77]. It is known, for instance, that a flood situation may reduce As(V) to the more toxic form As(III) [71]. Additionally, the increase in soil moisture content is normally associated with an increase in heavy metals bioavailability and, consequently, in their ecotoxicity in soil [71].…”

The interplay between metal contamination and climate change may exacerbate the negative impact on the soil microbiome and, consequently, on soil health and ecosystem services. We assessed the response of the microbial community of a heavy metal-contaminated soil when exposed to short-term (48 h) variations in air temperature, soil humidity or ultraviolet (UV) radiation in the absence and presence of Enchytraeus crypticus (soil invertebrate). Each of the climate scenarios simulated significantly altered at least one of the microbial parameters measured. Irrespective of the presence or absence of invertebrates, the effects were particularly marked upon exposure to increased air temperature and alterations in soil moisture levels (drought and flood scenarios). The observed effects can be partly explained by significant alterations in soil properties such as pH, dissolved organic carbon, and water-extractable heavy metals, which were observed for all scenarios in comparison to standard conditions. The occurrence of invertebrates mitigated some of the impacts observed on the soil microbial community, particularly in bacterial abundance, richness, diversity, and metabolic activity. Our findings emphasize the importance of considering the interplay between climate change, anthropogenic pressures, and soil biotic components to assess the impact of climate change on terrestrial ecosystems and to develop and implement effective management strategies.

“…Although many mechanisms of metal toxicity have not yet been elucidated, some points of consensus are emerging from the literature. Firstly, interactions between metals can occur outside the organism (including interactions with the environment (Grobelak and Kowalska, 2020;Noyes and Lema, 2015)), and during uptake into the organism, leading to potentially toxic processes of speciation, absorption, binding, transport and distribution (Wu et al, 2016).…”

Environmental pollutants can exert sublethal deleterious effects on animals. These include disruption of cognitive functions underlying crucial behaviours. While agrochemicals have been identified as a major threat to pollinators, metal pollutants, which are often found in complex mixtures, have so far been overlooked. Here we assessed the impact of acute exposure to field-realistic concentrations of three common metal pollutants, lead, copper, arsenic, and their combinations, on honey bee appetitive learning and memory. All treatments involving single metals slowed down learning and disrupted memory retrieval at 24 h. Combinations of these metals had additive negative effects on both processes, suggesting common pathways of toxicity. Our results highlight the need to further assess the risks of metal pollution on invertebrates.

“…Human health risk from heavy metals in soils might even increase due to a changing climate. Changing climate can alter the physicochemical soil properties and soil processes resulting in an increase of dissolved and bioavailable heavy metals (Rieuwerts et al 1998;Gonzalez-Alcaraz and van Gestel 2015;Grobelak and Kowalska 2020;Jarsjö et al 2020). In particular, soil metals from anthropogenic sources are more bioavailable than those of pedogenic origin (Kaasalainen and Yli-Halla 2003;Kabata-Pendias 2010).…”

Soils in the Lower Swansea Valley, (United Kingdom) contain elevated level of metals, enough to cause direct or indirect effects on human health. This study assesses the severity of soil pollution and bioavailability of Cu and other metals (Ni, Zn, Co, Pb and Cr) in soils with various distances from a Ni refinery. We compare Cu concentrations in operationally defined soil fractions (bioavailable, bound to Fe/Mn oxide and incorporated in organic matter) with other metals (Ni, Zn, Pb, Co, Cr) usually occurring in ores used in metallurgic processes and report their pollution and geoaccumulation indices (PI and I geo ). Further, we use Cu stable isotope ratios (d 65 Cu) to trace the fate and mobility of Cu in soils. Our data suggest a point source of contamination for some of the heavy metals including Ni (I geo = 1.9), Zn (I geo = 0.28) and Cu (I geo = 3.6) near the Ni refinery. However, Co (I geo = 0.15) and Pb (I geo = 3.3) contaminations are likely to be linked to different sources. No elevated Cr levels (I geo = -0.07) occur in any of the studied soils. All soil metals are predominantly associated with organic matter ([50%) which reduces their bioavailibility and thus their risk for ecological and human health. The Cu isotope data show that Cu in soil organic matter is enriched in 65 Cu, while the lighter isotopes ( 63 Cu) remain in the dissolved bioavailable Cu fraction (D 65 Cu organic-bioavailable is ?0.12 ± 0.13%). This suggests the preferential complexation of 65 Cu with soil organic matter after dissolution of Cu deposited to the soil. Thus, Cu isotope data can effectively indicate pathways of metal migration in polluted soils.
