It was a busy week for Adam and Graham participating in the virtual SETAC North America 41st Annual Meeting - SETAC SciCon2 between the 15th and 19th of November 2020. wca were involved in a number of presentations and posters on topics ranging from the read-across approach for endocrine disrupters to the reliability of bio-met for the site specific bioavailability normalisation of the environmental quality standards (EQS) for a number of metals. Adam was also one of the moderators for the water quality criteria discussion session and more details on this session can be found here.
The full list of posters:
- The read-across approach and data-gap fulling for endocrine disrupters: Case studies were used to illustrate the strengths and limitations on the use of read-across in endocrine disrupter assessments.
- Demonstrating the reliability of bio-met for the site-specific bioavailability normalisation for the EQS for nickel. Explaining the link between the 72 BLM validation tests for nickel, covering 9 different species in 20 different natural waters to the outputs provided by the simplified bioavailability tool bio-met*.
- Demonstrating the reliability of bio-met for the site-specific bioavailability normalisation for the EQS for copper. Explaining the link between the 62 BLM validation tests for copper, covering 11 different species in 22 different natural waters to the outputs provided by the simplified bioavailability tool bio-met*.
- Demonstrating the reliability of bio-met for the site-specific bioavailability normalisation for the EQS for zinc. Explaining the link between the 86 BLM validation tests for zinc, covering 14 different species in 24 different natural waters to the outputs provided by the simplified bioavailability tool bio-met*.
*More detail on this work can be found in a recent ET&C publication
The full list of presentations:
- A continent-wide, bioavailability-based environmental quality standard compliance assessment for metals, a European case study. Performing an indicative compliance assessment for Cu, Ni, Pb, and Zn in European freshwaters using bioavailability based Environmental Quality Standards.
- Urban run-off sources of several trace metals to wastewaters. Illustrating the importance of road transport as an important source of several trace metals into wastewaters from urban runoff.
- Derivation of an ecologically relevant nickel water quality standard in New Caledonia. A project being conducted assessing the applicability of bioavailability concepts for nickel developed in Europe, North American and Australia to New Caledonia, using local species and waters.
- Using field monitoring data to evaluate potential impacts of trace metals on Lymnaea stagnalis. Using ecological monitoring data from England and The Netherlands to assess whether the freshwater snail Lymnaea stagnalis is as sensitive to trace metals in the field as it appears to be from laboratory tests.
