“…The present study is the first published in the open literature that deals with sedimentspiked toxicity tests conducted with an insecticide using sufficient benthic arthropod species to allow an SSD approach in the sediment effect assessment procedure as proposed by EFSA (2015). SSDs constructed with toxicity data derived from sediment-spiked bioassays and benthic invertebrates belonging to various taxonomic groups have so far only been published for copper (Roman et al, 2007;Van der Meer, 2017), nickel (Besser et al, 2013) and the biocide tributyltin (Diepens et al, 2017).…”

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.

“…However, although PFAS are generally rather soluble in water (including those that sorb to solids), C free may not represent all potential uptake routes. Organisms interact with the abiotic environment through complex processes ( Van der Meer et al, 2017). Some organisms might be simultaneously exposed to the freely available fraction of PFAS in the porewater, and the accessible fraction sorbed onto solids (Jager, 1998).…”

Per‐ and polyfluorinated substances (PFAS) are a group of thousands ubiquitously applied persistent industrial chemicals. The field of PFAS environmental research is developing rapidly, but suffers from substantial biases towards specific compounds, environmental compartments, and organisms. The aim of this perspective was therefore to highlight current developments, and to identify knowledge gaps and subsequent research needs that would contribute to a comprehensive environmental risk assessment for PFAS. To this end, we consulted the open literature and databases, revealing that knowledge of the environmental fate of PFAS is based on the analysis of less than 1% of the compounds categorized as PFAS. Moreover, soils and suspended particulate matter (SPM) remain largely understudied. PFAS bioavailability, bioaccumulation and food web transfer studies also focus on a very limited number of compounds and are biased towards aquatic biota. Fish are predominantly studied, while aquatic invertebrates and macrophytes are included less frequently. The available ecotoxicity data revealed that only a few PFAS have been well‐studied for their environmental hazards, and that PFAS ecotoxicity data are strongly biased towards aquatic organisms as well. This emphasizes the need to catch up with ecotoxicity studies in the terrestrial environment. Considering the persistency and bioaccumulation of PFAS, more chronic, multigeneration and community ecotoxicity studies are needed. Finally, we identified the urgent need to unravel the relationship between sorption, bioaccumulation and ecotoxicity on the one hand and molecular descriptors of PFAS chemical structures and physicochemical properties on the other, to enable prediction of exposure, bioaccumulation and toxicity.
