Expert advice in designing fish and amphibian tests for endocrine disruption

February 19, 2019 by Becky Brown

At wca we specialise in Endocrine Disrupter (ED) assessments for chemicals. In recent years we have conducted ED assessments for pharmaceuticals, general chemicals under REACH, and for multiple plant protection products (PPPs). The European Commission (EC) is strengthening regulation in this area through the introduction of ED criteria for biocides and PPPs, with associated guidance. The draft new guidelines for the environmental risk assessment of pharmaceuticals also includes special provision for endocrine active substances.

Comparison of the chronic toxicity of nickel to temperate and tropical freshwater species

February 13, 2019 by Iain Wilson

Reliable ecotoxicity data are required to derive thresholds protective for aquatic life that are scientifically defensible and practically implementable as environmental risk assessment and management tools. Adam Peters, Graham Merrington, Dean Leverett and I, along with Chris Schlekat and Emily Garman of NiPERA have recently published a paper regarding this issue in the journal Environmental Toxicology and Chemistry.

January 18, 2019 by Olivia Tran

The UK’s plan for ecolabelling after Brexit was briefly discussed in the Resources and Waste Strategy, published in December 2018.

Latest updates


March 17, 2020 by Dean Leverett

At this difficult and testing time for everyone, I thought it might be useful to highlight the arrangements that wca are putting in place to deal with the Covid-19 outbreak.

March 3, 2020 by Ed Stutt

ECHA has recently published a report based on a project conducted by wca at the end of last year. Working in collaboration with ECHA, Ed and Olivia carried out market research to estimate the number of applications for 11 substances of very high concern (SVHCs) that the European Commission added to the Authorisation List in February 2020.

February 10, 2020 by Sylwia Kosmala-Grzechnik

ECHA’s concerns that companies are not keeping their REACH registrations up to date has led to the drafting of an Implementing Regulation, setting out a deadline of 3 months for submitting administrative updates, and deadlines of 6 or 12 months for updates which are considered more complex and require generating new data or changes in the safety assessment.
