How to analyse and account for interactions in mixture toxicity with toxicokinetic-toxicodynamic models.

Sci Total Environ 2022 Jun 29:157048. Epub 2022 Jun 29.

Department of Environment and Geography, University of York, Heslington, York YO10 5NG, UK; Syngenta Crop Protection AG, Basel, Switzerland.

The assessment of chemical mixture toxicity is one of the major challenges in ecotoxicology. Chemicals can interact, leading to more or less effects than expected, commonly named synergism and antagonism respectively. The classic ad hoc approach for the assessment of mixture effects is based on dose-response curves at a single time point, and is limited to identifying a mixture interaction but cannot provide predictions for untested exposure durations, nor for scenarios where exposure varies in time.

Investigating the mechanisms of dissolved organic matter protection against copper toxicity in fish of Amazon's black waters.

Sci Total Environ 2022 Jun 29:157032. Epub 2022 Jun 29.

Department of Zoology, University of British Columbia, Vancouver, BC V6T 1Z4, Canada.

We investigated how natural dissolved organic matter (DOM) of the Rio Negro (Amazon) affects acute copper (Cu) toxicity to local fish: the cardinal tetra (Paracheirodon axelrodi) and the dwarf cichlid (Apistogramma agassizii). It is established that Cu2+ complexation with DOM decreases Cu bioavailability (and thus toxicity) to aquatic organisms, as conceptualized by the Biotic Ligand Model (BLM). However, we also know that Rio Negro's DOM can interact with fish gills and have a beneficial effect on Na + homeostasis, the main target of acute Cu toxicity in freshwater animals. Read More
