“…Factors such as soil pH and organic matter content directly affect Cd availability to the soil (Liu et al, 2018;Mortensen et al, 2018). At higher pH, Cd availability decreases due to the increase in its adsorption to the charges of the soil and less accessible sites of organic matter, reducing its availability in the soil matrix (Mortensen et al, 2018).…”

“…Thus, the results found indicate that ash application in soils such as the Entisol, in addition to directly affecting soil pH, which exceeded the tolerance of the organisms at the highest concentrations tested, affecting their reproduction (Table 3), may also be promoting the availability of elements such as Cd. Authors such as Liu et al (2018) found EC 50 from 41.4 to 146.9 mg Cd kg -1 of soil for F. candida when assessing the effect of Cd toxicity on different soils, and found a high correlation of the toxicity response associated with the values of pH and organic matter of these soils. For earthworms, similarly, studies indicate that soil pH and organic matter content affect the bioaccumulation and toxicity (Irizar et al, 2015).…”

The forest biomass ash used in agriculture as fertilizer has characteristics that can negatively affect the terrestrial environment. This study aimed to evaluate the effect of the application of eucalyptus forest biomass ash on springtails and earthworms in subtropical soils through ecotoxicological tests. The subtropical soils Oxisol and Entisol were used for the ecotoxicological tests of survival and reproduction of springtails (Folsomia candida) and earthworms (Eisenia andrei). The concentrations of forest biomass ash were 0, 5 10 and 20 t ha -1 , based on the recommendation of the application of plant ash as fertilizer. The ecotoxicological results obtained in Oxisol demonstrate that earthworms and springtails are not affected by the presence of ash. In Entisol, the results of sensitivity of the organisms were more evident, and effects were observed from the dose of 5 t ha -1 for springtails with estimated LC 50 of 15.68 t ha -1 (CI: not calculated) and EC 50 of 7.36 t ha -1 (CI: 7.11-7.62 t ha -1 ). Earthworms were affected from 10 t ha -1 , with an estimated EC 50 of 11.97 t ha -1 (CI: 9.49-14.46 t ha -1 ). Application of forest biomass ash in the soil negatively affects springtails and earthworms, but the magnitude of the effects is mainly related to characteristics of the soil, amount applied and sensitivity of the species; negative effects of ash application are directly related to the change in soil pH.

“…Therefore, the standard single-species test should not be generalized for a wide range of soil pH values. Instead, the standard single-species test animal should be speci ed for certain ranges of pH values (Fountain and Hopkin, 2005;Howcroft et al, 2009;Liu et al, 2019). An alternative explanation is hormesis effects, demonstrating stimulatory or bene cial effects occurring at a lower dose, but inhibitory or toxic effects at a higher dose (Mark, 2008;Gospodarek et al, 2020).…”

“…Notably Folsomia candida, because of its sensitivity to pollutants, ease of culture, short life cycle, and high reproduction rate et al (Coyle et al, 2017). Laboratory studies show that high Cd concentrations signi cantly decreased collembolan survival and reproduction rates, growth (body weight and body length), and locomotor behavior (Lock and Janssen, 2001a, b; Kim and An, 2014; Liu et al, 2019).…”

“…Studies indicate that soil organic matter content, soil pH, and clay, iron, and manganese oxide contents, etc. have signi cant relationships with Cd toxicity to and accumulation in collembolans (Lock and Janssen, 2001a, b;van Gestel, 2008;Liu et al, 2019). In addition, these soil properties are commonly incorporated into empirical models (single and multiple linear regression equations) to build empirical equations for the prediction of Cd toxicity to and accumulation in collembolans (Liu et al, 2019).…”

Accurate prediction of cadmium (Cd) ecotoxicity to and accumulation in soil biota is important in soil health. However, very limited information on Cd ecotoxicity on naturally contaminated soils. Herein, we investigated soil Cd ecotoxicity using Folsomia candida, a standard single-species test animal, in 28 naturally Cd-contaminated soils, and the back-propagation neural network (BPNN) model was used to predict Cd ecotoxicity to and accumulation in F. candida. Soil total Cd and pH were the primary soil properties affecting Cd toxicity. However, soil pH was the main factor when the total Cd concentration was ˂ 3 mg kg− 1. Interestingly, correlation analysis and the K-spiked test confirmed nutrient potassium (K) was essential for Cd accumulation, highlighting the significance of studying K in Cd accumulation. The BPNN model showed greater prediction accuracy of collembolan survival rate (R2 = 0.797), reproduction inhibitory rate (R2 = 0.827), body Cd concentration (R2 = 0.961), and Cd bioaccumulation factor (R2 = 0.964) than multiple linear regression models. Then the developed BPNN model was used to predict Cd ecological risks in 57 soils in southern China. Compared to multiple linear regression models, the BPNN models can better identify high-risk regions. This study highlights the potential of BPNN as a novel and rapid tool for the evaluation and monitoring of Cd ecotoxicity in naturally contaminated soils.

The interaction of Cd and other heavy metals with soil colloidal particles controls the sequestration, mobility and bioavailability of Cd in soils. In this study, the binding (△Gbi) and adsorption (△Gad) energies of Cd on colloidal particles of 18 soils were determined by the Wien effect method. The binding energy of Cd on soil colloidal particles varied from 5.3 to 9.9 kJ mol−1, depending on the soil characteristics including pH, Mn‐oxide content and dissolved organic carbon in the soil. The Cd adsorption energy correlated positively with Mn‐oxide content and pH. In parallel, the extended X‐ray absorption fine structure (EXAFS) spectroscopy was used to determine the speciation of Cd in Cd‐saturated soil samples, which revealed that the outer‐sphere Cd was the predominant species, accounting for 32.2–73.7% of the total adsorbed Cd, and positively correlated to the binding and adsorption energies. Humic acid‐Cd (10.4–42.2%) and montmorillonite‐Cd (2.5–51.2%) were also major species that were identified by EXAFS spectroscopy. The toxicity (log EC50) of Cd in soils to three organisms (earthworm, Collembola and Chinese cabbage) was found to correlate positively with the binding energies, indicating the predictive capability of using binding energies of Cd in different soils as an indicator for evaluating Cd bioavailability and toxicity in soils.
