Refinery effluent assessment: Options for using effects-based tools in combination with passive samplers

September 19, 2018 by Becky Brown

wca has conducted a critical evaluation of available “effects based tools” (EBTs) that could be used in conjunction with passive samplers in monitoring surface waters associated with the oil and gas industry. The study is based on a literature review of monitoring data for twenty-two assays, including some novel whole organism bioassays (or surrogate for whole organism effects), and in vitro or bacterial assays designed to assess the potential for endocrine (oestrogen, androgen and thyroid), genotoxicity, oxidative stress, and metabolism effects from polyaromatic hydrocarbons (PAHs).

Updating and upgrading NONS registrations under REACH

August 8, 2018 by Rhiannon Smith

NONS substances (Directive 67/548/EEC) can be regarded as REACH registered, however maintenance of the registration is necessary to keep it up to date, to change tonnage bands, to join a joint submission, or in response to a request from ECHA. wca can assist companies who have submitted NONS notifications.

Beyond registration…what next for REACH?

July 24, 2018 by Becky Marks

With the passing of the final REACH registration deadline for phase in substances in May, many breathed a sigh of relief at having accomplished the successful registration of their substances. But we all know registration was only the start of the REACH process, so what next?

Endocrine disruptors and biocides

June 19, 2018 by Becky Brown

The new endocrine disrupter criteria for biocides apply from the 7th June 2018 under Regulation (EU) No 528/2012 . This means that new biocides and biocides currently going through the authorisation process will need to have an endocrine disrupter assessment included as part of their application.

Nanosilver less toxic than ionic silver in standardised ecotoxicity tests

May 3, 2018 by Dean Leverett

During 2017, Dean was part of a team of scientists supporting a REACH testing programme aimed at comparing the ecotoxicity of the ionic and nano forms of silver using standardised tests. As part of the REACH Substance Evaluation for silver, a read-across approach from ionic silver to silver nanoforms was proposed based on existing ecotoxicity data. However, further justification of this read-across approach was requested and therefore standardised ecotoxicity and fate/ behaviour tests were undertaken to directly compare the toxicity of ionic silver and the smallest silver nanoform with the highest specific surface area registered under REACH. A paper detailing the results of the comparative testing programme in soil will shortly be published.

Under UK REACH, all companies producing or importing substances into Great Britain at ≥ 1 tonne per annum must submit a registration to the UK Health and Safety Executive (HSE). Substances which have been grandfathered or have been notified by a Downstream User Import Notification (DUIN) need to have a full registration submitted by the transitional registration deadlines.
