“…Although plants can modulate the local availability of HM in the rhizosphere, for example due to root exudation [130]- [132], their effect was likely masked by the extreme loads of Cu and Cd oversaturating the soil. Indeed, the modulation of HM availability by soluble organic ligands has been shown at low concentrations [133], [134].…”

A Matter of Metals: Copper but Not Cadmium Affects the Microbial Alpha-Diversity of Soils and Sediments — a Meta-analysis

et al. 2022

Heavy metal (HM) accumulation in soil affects plants and soil fauna, yet the effect on microbial alpha-diversity remains unclear, mainly due to the absence of dedicated research synthesis (e.g. meta-analysis). Here, we report the first meta-analysis of the response of soil microbial alpha-diversity to the experimental addition of cadmium (Cd) and copper (Cu). We considered studies conducted between 2013 and 2022 using DNA metabarcoding of bacterial and fungal communities to overcome limitations of other cultivation- and electrophoresis-based techniques. Fungi were discarded due to the limited study number (i.e. 6 studies). Bacterial studies resulted in 66 independent experiments reported in 32 primary papers from four continents. We found a negative dose-dependent response for Cu but not for Cd for bacterial alpha-diversity in the environments, only for Cu additions exceeding 29.6 mg kg−1 (first loss of − 0.06% at 30 mg kg−1). The maximal loss of bacterial alpha-diversity registered was 13.89% at 3837 mg kg−1. Our results first highlight that bacterial communities behave differently to soil pollution depending on the metal. Secondly, our study suggests that even extreme doses of Cu do not cause a dramatic loss in alpha-diversity, highlighting how the behaviour of bacterial communities diverges from soil macro-organisms.

“…Similar changes in soil acidity were observed by John et al [ 61 ]. The soil reaction is considered to be one of the principal factors influencing the quantities of phytoavailable forms of trace elements [ 62 ]. A decrease in the soil reaction to slightly acidic and acidic elements stimulates the mobility of available forms of trace elements, thereby raising the risk of increasing the indicator of their translocation to shoots [ 63 , 64 ].…”

Sewage Sludge as a Tool in Limiting the Content of Trace Elements in Avena sativa L. on the Soil Polluted with Diesel Oil

The aim of the research was to determine the effect of soil contamination with diesel oil (0; 5; 10 and 15 cm3 kg−1 of soil) on the content of trace elements in the aboveground parts of oat (Avena sativa L.). Stabilised sewage sludge was used to mitigate the likely negative impact of diesel oil on the plant. Growing soil contamination with diesel oil had a significant impact on the content of trace elements in the aboveground biomass of oat. In the series without sewage sludge, the contents of the analysed elements, except for chromium, zinc, copper and cobalt, were positively correlated with the increasing doses of diesel oil. The largest increase in the content was recorded in the case of manganese. The sewage sludge used to reduce the influence of diesel oil on the chemical composition of oat had a positive effect on the content of the analysed trace elements. Compared to the series without the addition of a stabilised sewage sludge, it contributed to a reduction in the average content of chromium, nickel, copper, manganese and cobalt in the aboveground parts of oat plants. No significant effect of the applied remediation treatment was noted for cadmium, and the results were equivocal for iron.
