Influence of metal speciation on soil ecotoxicity impacts in life cycle assessment

Comparison of three typical lithium-ion batteries for pure electric vehicles from the perspective of life cycle assessment

“…The Toxicity and Ecotoxicity Potential (TETP) aims to assess the impact of various toxic and harmful factors on soil ecosystems (Sydow, Chrzanowski et al 2020). Fig.…”

Identification of dissipative emissions for improved assessment of metal resources in life cycle assessment

“…The multimedia fate module of USEtox® 2.1 (LC‐Impact version) was used to calculate steady state environmental concentrations resulting from global emissions corresponding to the current annual emission rate (Fantke et al., 2017; Verones et al., 2020). It considers metal speciation in solid and liquid phases of the soil and is applicable to elements emitted from anthropogenic sources (Owsianiak et al., 2013, 2015; Sydow et al., 2020). It allows for simulation of environmental concentrations in six environmental compartments (i.e., rural air, urban air, freshwater, sea water, natural soil, agricultural soil) resulting from emissions to any compartments.…”

Trace contaminants in the environmental assessment of organic waste recycling in agriculture: Gaps between methods and knowledge

“…They observed that CTP values and concomitant impact scores calculated with the speciation-based method were not systematically markedly lower than those calculated with IMPACT 2002+ or ReCiPe 2008 methods. Sydow et al (2020) further found that, when accounting for their solid and solution speciation in soils, trace elements still contributed to more than 90% of the total terrestrial ecotoxicity impact score (with less than 10% due to organic contaminants). These authors thus concluded that increasing the substance coverage of LCIA methods would be as beneficial as increasing their environmental relevance by considering trace element speciation in soils.…”

“…Most of risk assessment methodologies point out trace elements as the type of contaminants that dominates the impacts on human health and, even more so, on aquatic and terrestrial ecotoxicity (Pettersen and Hertwich, 2008;Pizzol et al, 2011aPizzol et al, , 2011bTarpani et al, 2020). The robustness of these methodologies has, however, been questioned as they do not account for the speciation and bioavailability which are essential factors in determining the toxicological and ecotoxicological impacts of trace elements (Plouffe et al, 2016(Plouffe et al, , 2015a(Plouffe et al, , 2015bSydow et al, 2020). It would therefore be essential to develop robust risk assessment methodologies specifically focused on the input of trace elements from raw and transformed OW in agricultural soils to ensure the sustainability of agricultural recycling of OW.…”

“…Concomitantly, these overall results suggest that the contribution of trace elements to the terrestrial ecotoxicity impact score derived from current LCIA approaches is overestimated, thus highlighting the need to further account for trace element speciation and bioavailability. This conclusion was, however, recently challenged by the findings of Sydow et al (2020) based on a comparison of the speciationbased method developed by Owsianiak et al (2015Owsianiak et al ( , 2013 and the toxicity models implemented in the widely used IMPACT 2002+ and ReCiPe 2008 methods for ˜13 000 life cycles of unit processes.…”
