Mitigation of bottlenecks in ecotoxicological EDC testing capacities

 

Dr. Viktoria Urban (Regulatory Scientific Expert Ecotoxicology at Vali) was one of the speakers at the virtual conference Biocides Europe 2021.

Her presentation “Mitigation of bottlenecks in ecotoxicological EDC testing capacities“ dealt with capacity issues and challenges of labs for ecotoxicological EDC testing as well as mitigation options for potential bottlenecks:

 

Since 2018 there are scientific criteria for ED applicable for biocides and pesticides. After three years of ED testing in European labs, most labs established level 3 studies, are able to run fish level 4 studies (which are rarely conducted), but are not prepared for fish level 5 and frog level 4 studies. To get a study done, expect 2 years of waiting time.

 

Challenges in the test capacity contain space and equipment of the laboratories. More diluter systems, water capacity and space are often needed, but not every lab can afford this.

There are also challenges concerning test organisms: Fatheads are not available in Europe and are shipped from only a few suppliers in US. A high number of animals is needed and the time to reproduction stage is 4 to 6 months. So, in house-breeding and large breeding capacities are needed.

Another challenge is the fish health: Pathogens in fish are common. So, there is a high risk with each import. Regular controls of fish health are necessary.

Further challenges lie in long-term studies, because there is no data requirement in EU from before 2018. So, only little experience is available. There are also high costs for implementation and lab capacities are already booked up, which complicates establishing long-term studies.

 

To avoid bottlenecks it is important to start early with study preparation, evaluate available data and tailor an appropriate test strategy. If data and substance properties allow, the use of short embryo-based tests might be helpful. To avoid repetition of testing, ensuring health of test organisms and experience of histopathological partner labs are important. Increasing output of studies by setting appropriate test concentrations and considering inclusion of liver histopathology to check for systemic toxicity are an approach. A faster update and development of guidelines as well as realistic validity criteria for the labs in the guidelines could help to avoid bottlenecks.

Biocides in UK/Resubmission for ongoing applications

 

With regard to Brexit the United Kingdom has implemented its own system to regulate biocides.

As a consequence, as of 1 January 2021 UK has no longer access to EU IT systems such as R4BP3, thus, it is no longer posssible for UK authorities to access ongoing applications in the EU and the respective data sets.
