“…Lipophilic pesticides are frequently detected in sediments of edge-of-field freshwater ecosystems (e.g., Warren et al, 2003;Stehle and Schulz, 2015;Li et al, 2017;, potentially leading to long-term toxic effects on benthic organisms and communities (e.g., Ding et al, 2010;Schäfer et al, 2011;MacKnight et al, 2015;Hunt et al, 2016;Moran et al 2017). These potential ecological risks of sediment-bound pesticides were confirmed by a few micro-/mesocosm experiments conducted with spiked sediment (Boyle et al, 2016;Brock et al, 2016;Rogers et al, 2016;Yin et al, 2018).…”

This paper deals with species sensitivity distributions (SSDs) for the lipophilic insecticide lufenuron and benthic arthropods based on sediment-spiked laboratory toxicity tests. This compound that inhibits chitin synthesis and moulting of arthropods persists in sediment. Using field-collected sediment, toxicity tests were conducted with three macro-crustaceans and six insects. The Hazardous Concentration to 5% of the tested species, the HC5 (and 95% confidence limit), derived from an SSD constructed with 10d-LC50's was 2.2 (1.2-5.7) μg/g organic carbon (OC) in dry sediment. In addition, HC5 values derived from SSDs constructed with 28d-LC10 and 28-d LC50 values were 0.13 (0.02-1.50) μg/g OC and 2.0 (1.3-5.5) μg/g OC, respectively. In 28d toxicity tests with Chironomus riparius and Hyalella azteca, a higher sensitivity was observed when using lufenuron-spiked field-collected sediment than in lufenuron-spiked artificial sediment. Overall, the non-biting midge C. riparius appeared to be a representative and sensitive standard test species to assess effects of lufenuron exposure in sediment. The Tier-1 (based on standard test species), Tier-2 (based on standard and additional test species) and Tier-3 (model ecosystem approach) regulatory acceptable concentrations (RACs) for sediment-spiked lufenuron did not differ substantially. The Tier-2 RAC was the lowest. Since to our knowledge this study is the first in the open literature that evaluates the tiered approach in the sediment effect assessment procedure for pesticides, we advocate that similar evaluations should be conducted for pesticides that differ in toxic mode-of-action.

“…Although the use of these endpoints provides a more sensitive evaluation of risk, in many cases the use of Chironomus may still underestimate risk because this species is considered very tolerant (Carew et al 2011;Mehler et al 2017). Studies have also shown increases (Boyle et al 2016) and decreases (Hatakeyama and Yasuno 1981;Goedkoop et al 2010) in mean development rate attributable to the presence of contamination; hence, characterizing risk using this endpoint alone is difficult and should be done with caution. For example, amphipods (i.e., Hyalella azteca) have also shown reduced growth and in some cases mortality with the addition of the nonpolar organic amendment (US Environmental Protection Agency 2007).…”

“…However, the proposed alterations could also be used with more sensitive species. For instance, wing length has been used successfully in multiple studies to characterize fitness of Chironomus when exposed to contaminants (Frouz et al 2002;Goedkoop et al 2010;Boyle et al 2016). Adding endpoints (perhaps ability to molt and/or reproduction) and activated carbon treatments could further enhance the accuracy and influence of whole-sediment TIEs for this species as well.…”

“…The increased mean development rate of the sediment when compared with control could have been attributable to a combination of factors, such as organic carbon differences, nutrient loadings, or other sediment factors (Ristola et al 1999). Studies have also shown increases (Boyle et al 2016) and decreases (Hatakeyama and Yasuno 1981;Goedkoop et al 2010) in mean development rate attributable to the presence of contamination; hence, characterizing risk using this endpoint alone is difficult and should be done with caution. Further work to understand the significance of an alteration in mean development rate and its implications in understanding risk is needed before this could be used as a suitable endpoint in whole-sediment TIE testing.…”

“…Additional evaluations using biomarkers (such as lipid content), metabolomics, or other behavioral/physiology endpoints may make the use of Chironomus more environmentally relevant. For instance, wing length has been used successfully in multiple studies to characterize fitness of Chironomus when exposed to contaminants (Frouz et al 2002;Goedkoop et al 2010;Boyle et al 2016). Further work to better understand the overall sensitivity of these additional endpoints to contaminants as well as their sensitivity to activated carbon would enhance the accuracy of wholesediment TIEs.…”

Resolving the false‐negative issues of the nonpolar organic amendment in whole‐sediment toxicity identification evaluations

Three common false-negative scenarios have been encountered with amendment addition in whole-sediment toxicity identification evaluations (TIEs): dilution of toxicity by amendment addition (i.e., not toxic enough), not enough amendment present to reduce toxicity (i.e., too toxic), and the amendment itself elicits a toxic response (i.e., secondary amendment effect). One such amendment in which all 3 types of false-negatives have been observed is with the nonpolar organic amendment (activated carbon or powdered coconut charcoal). The objective of the present study was to reduce the likelihood of encountering false-negatives with this amendment and to increase the value of the whole-sediment TIE bioassay. To do this, the present study evaluated the effects of various activated carbon additions to survival, growth, emergence, and mean development rate of Chironomus tepperi. Using this information, an alternative method for this amendment was developed which utilized a combination of multiple amendment addition ratios based on wet weight (1%, lower likelihood of the secondary amendment effect; 5%, higher reduction of contaminant) and nonconventional endpoints (emergence, mean development rate). This alternative method was then validated in the laboratory (using spiked sediments) and with contaminated field sediments. Using these multiple activated carbon ratios in combination with additional endpoints (namely, emergence) reduced the likelihood of all 3 types of false-negatives and provided a more sensitive evaluation of risk.

Information on the effects of pollutants in sediments at an ecosystem level to validate current and proposed risk‐assessment procedures is scarce. The most frequent criticism of these procedures is that responses of surrogate species in the laboratory are not representative of responses of natural populations. A tiered approach using both laboratory and microcosm exposures (96‐h and 21‐d laboratory bioassays and a 3‐mo field microcosm) was conducted to compare the impacts of sediment‐spiked cadmium on the mortality, development, and abundance of Chironomidae larvae. The 96‐h and 21‐d lethal concentrations of sediment‐spiked Cd to 50% of the species Chironomus riparius were estimated to be 201.07 and 172.66 mg/kg, respectively. In the 21‐d laboratory bioassay, the endpoints, including the development rate and emergence ratio, were compared, and the lowest‐observed‐effect concentration (LOEC) values were 325.8 and 10.7 mg/kg, respectively. The abundance, richness, and biomass of field‐collected larvae were compared among the different treatments in the field microcosm, and it was found that the order of sensitivities using different endpoints was biomass (2.6/5.2 mg/kg of no‐observed‐effect concentration/LOEC) > diversity (10.7/21.2 mg/kg) > abundance (41.2/82.7 mg/kg). The toxicity values based on lethal/sublethal changes in the laboratory bioassays might not fully protect field organisms against damage from chemicals, such as Cd, unless an assessment factor of 5 is used. These findings highlight the need to conduct field validation of criteria/guidelines before they are introduced to protect organisms/ecosystems in the field and provide a preliminary template for future field validation of criteria elsewhere.
