“…Thus, the potential use of ash is influenced by its contaminants (e.g. metals), which depend on the source of biomass used (Cruz-Paredes et al, 2017;Khan et al, 2009), and may cause negative environmental impacts when incorrectly disposed (Anderson et al, 2013;Huotari 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.

“…A similar approach was employed with the toxicity dataset as an independent external validation. This study [28] may be regarded as an attempt to develop a "universal" methodology to estimate metals bioavailability for soil-dwelling organisms and to formulate the decision rule for corresponding ecological risk assessment.…”

“…Recently, a quantitative assessment tool has been proposed that characterizes typical aerobic soils in terms of their potential to sequester common divalent metal cations and mitigate their bioavailability to soil-dwelling biota [28]. Two representative datasets were established from relevant literature; one included data from studies related to bioaccumulation, while the other contained data from studies related to toxicity.…”

Definitions and terms related to bioavailability and bioaccessibility of trace metals/metalloids and organic contaminants in soil are briefly discussed and critically evaluated. Main distinguishing features of estimating the bioavailability by biological (in vivo) methods are characterized. Assessment of bioaccessibility using biomimetric (in vitro) methods and existing correlations with in vivo tests are summarized. The most promising biomimetric methods can be as follows: CaCl 2 extraction for the assessment of metals biouptake into plants; solid-phase micro extraction, supercritical fluid extraction (SFE) under mild conditions as well as Tenax and hydroxypropyl-beta-cyclodextrin (HPCD) extractions for the estimation of biouptake of persistent organic compounds (e.g., polynuclear aromatic hydrocarbons and polychlorinated biphenyls) by soil-dwelling organisms (mainly earthworms); SFE under mild conditions, HPCD and Tenax extraction for the prediction of biodegradability (microbial degradation) of organic contaminants. However, method development should be extended to further classes of substances. In addition, multidisciplinary approaches are needed for (i) standardization and round-robin studies of the most promising biomimetric methods and protocols so that the data obtained in different laboratories can be compared; (ii) further assessment and critical evaluation of correlations between in vitro and in vivo tests; application of chemometric techniques for handling sets of data obtained both by biomimetric and biological methods is of particular importance in order to evaluate new criteria for risk assessment.

“…Translating the latter factors to field‐contaminated soils still has shortcomings because metal(loids) in the field have different speciation from those in spiked soils, even after sufficient equilibration or leaching is included (Alvarenga et al 2012; Hamels et al 2014). A potential solution to this variable speciation is to use specifically calibrated soil extractions as a proxy of the so‐called “available dose” (Anderson et al 2013; Kim et al 2015). The key prerequisite for this approach is that it needs sufficient calibration data.…”

The validity of soil toxicity databases for predicting ecological impacts in the field is rarely explored. The present study was set up to test whether laboratory toxicity data and the combined concepts of metal availability and mixture toxicity can predict ecological impact in mining‐affected soils. Metal and As contamination gradients were sampled approximately 5 different mines in Mexico where plant cover and abundances exhibited clear dose‐related responses. Soils were analyzed for total and isotopically exchangeable (labile) concentrations of Ni, Cu, Cd, Pb, and As and for soil properties affecting the availability of these elements. Six different indices of toxic doses were compared to evaluate their accuracy in describing the field response expressed as relative abundance and cover. Each index was based on a different method to calculate the sum of toxic units (normalΣTUs) in soil, with 1 toxic unit equal to the concentration of the element in soil yielding 50% adverse effect on plants with median sensitivity as recorded in a recent database of salt‐spiked soils. Toxic concentrations in the mine‐impacted soils were dominated by Zn and As. In the field, 50% reduced cover or abundance was found at 10 to 13 normalΣTUs if these were based on total soil concentrations and thresholds derived from freshly spiked soils, indicating a largely overestimated toxic effect. If thresholds were corrected for differences in availability among freshly spiked soils and spiked and laboratory‐aged soils, the overestimation of field toxicity was 5‐ to 6‐fold, irrespective of the consideration of soil properties. Finally, the normalΣTU calculated only with labile metals and As overestimated the field toxicity by factors 1.1 to 1.6 (95% confidence interval 1–7; i.e., rather accurate and indicating some Zn–As antagonism as confirmed in experimental studies). That latter index of dose yielded a bell‐shaped response on species richness peaking at approximately 1.6 normalΣTU. Overall, the present study shows that the current toxicity databases of metals can predict the impact of metal contamination on plant communities within factor 2, expressing the dose as soil‐labile concentrations and using the concentration addition concept in these mixed polluted environments.
