“…we observed at cooler relative to warmer sites is in apparent contradiction to single species short-term laboratory studies that show a greater effect of salinity at higher temperatures (Cañedo Argüelles et al, 2013;Jackson & Funk, 2019;Moulding et al, 2022). Such inconsistencies between experiments and our findings reinforce the general point that context matters in determining the cumulative effects of multiple stressors.…”

“…For example, we found little evidence of a strong interaction between turbidity and temperature, in contrast to two mesocosm experiments where increased sedimentation and higher temperature had a strong antagonistic effect on EPT genus richness (Piggott et al, 2012 , 2015a ). Similarly, the greater effect of EC (salinity) on EPT family richness we observed at cooler relative to warmer sites is in apparent contradiction to single species short‐term laboratory studies that show a greater effect of salinity at higher temperatures (Cañedo Argüelles et al, 2013 ; Jackson & Funk, 2019 ; Moulding et al, 2022 ). Such inconsistencies between experiments and our findings reinforce the general point that context matters in determining the cumulative effects of multiple stressors.…”

“…We are unsure why elevated EC was associated with a greater reduction in EPT family richness at cool relative to warm sites. This outcome runs counter to single‐species short‐term laboratory experiments (Cañedo Argüelles et al, 2013 ; Dunlop et al, 2008 ; Jackson & Funk, 2019 ; Moulding et al, 2022 ), although outcomes may differ over the long term (Moulding et al, 2022 ; Orr & Buchwalter, 2020 ; Verberk et al, 2020 ). Much of the variation in scaled water temperature among sites was associated with changes in latitude (Figure S4 ).…”

“…However, they focus on marine aquatic life (Greenstein et al 2004 ; Schiff et al 2003 ), three freshwater species (water flea Ceriodaphnia dubia , fathead minnow Pimephales promelas , and green algae Pseudokirchneriella subcapitatum ) and the luminescent bacteria Photobacterium phosphoreum using Microtox™ (Kayhanian 2010 ; Kayhanian et al 2008 ). The toxicity of various products used for winter road maintenance on the freshwater biota mayfly Colobruscoides giganteus (Ephemeroptera: Colobruscoidea) was assessed by Moulding et al ( 2022 ).…”

Urban road dust (URD) is one of the most important non-point sources of pollution in agglomerations. The aim of this study was to assess the seasonal toxic effects of URD runoff in two regions of Poland. The concentrations of elements in URD and leachate were studied. The impact of pollutants in URD runoff on water organisms was evaluated using Daphtoxkit F and Rotoxkit F (LC50). The acute toxicity tests for crustaceans and rotifers were selected as the response of these taxa reflects the impact on zooplankton, a key component of aquatic ecosystem and the basis of most food webs. The concentrations of elements were found to vary depending on the site, although URD samples collected in Katowice agglomeration (Upper Silesia) had higher values of elements (Mn, Cu, Zn, As) compared to Wrocław (Lower Silesia). The concentrations of Mn, Zn, As, Cr, and Mg in water-soluble fraction of URD were higher in summer and winter in the Upper Silesia region due to rainwater runoff resulting from traffic, industries, post-industrial waste, and the presence of old heating systems. When comparing the content of elements in the water-soluble fraction between seasons, Zn, As, Cr, and Al concentrations were slightly higher in winter. The highest mortality of Daphnia magna and Brachiouns calyciflorus was observed in URD from both agglomerations in winter. However, the mortality is likely due to the concentration of elements or/and the coexistence of an unknown compound or a synergistic effect of the studied elements. This study highlights the alarming seasonal sources of elements in URD runoff, which will directly enter the food chain and affect the entire ecosystem, and human health.

Toxicokinetic–toxicodynamic (TKTD) modeling has received increasing attention in terms of the regulatory environmental risk assessment of chemicals. This type of mechanistic model can integrate all available data from individual‐level bioassays into a single framework and enable refined risk assessments by extrapolating from laboratory results to time‐variable exposure scenarios, based, for instance, on surface water exposure modeling (e.g., FOCUS). Dynamic energy budget (DEB) models coupled with TKTD modules (DEB–TKTD) constitute the leading approach to assess and predict sublethal effects of chemicals on individual organisms. However, thorough case studies are rare. We provide a state‐of‐the‐art example with the standard aquatic test species Ceriodaphnia dubia and the fungicide azoxystrobin, including all steps, from bespoke laboratory toxicity tests to model calibration and validation, through to environmental risk assessment. Following the framework proposed in the European Food Safety Authority Scientific Opinion from 2018, we designed bespoke good laboratory practice–compliant laboratory toxicity studies based on test guideline 211 of the Organisation for Economic Co‐operation and Development and then identified robust parameter values from those data for all relevant model parameters through model calibration. The DEB–TKTD model, DEBtox2019, then informed the design of the validation experiment. Once validated, the model was used to perform predictions for a time‐variable exposure scenario generated by FOCUS. A moving time‐window approach was used to perform the environmental risk assessment. This assessment method reduces uncertainty in the risk assessment while maintaining consistency with the traditional measures of risk.
