Priority questions from the SETAC Science Committee

Posted By Tamara L. Sorell, Sunday, February 12, 2017

The SETAC Science committee, on behalf of the SETAC Board, has asked the IGs to assist in identifying priority research questions that might warrant a SETAC Focus Topic Meeting or workshop. 

 

Please take a few minutes and respond to this blog with your thoughts this week.

 

1.       What are the best methods to measure bioavailable/freely-dissolved/chemical activity of organic chemicals and metals in environmental media?

2.       How do we develop methods to identify and quantify nano- and microplastics in different environmental compartments (water, sediment, soil, biota) associated with potential toxicity or interactions with other contaminants?

3.       How can we strengthen the environmental quality criteria system (e.g, water, sediment, soil, air) to adequately protect ecosystems that are experiencing multiple stressors and changing climate?

4.       Do you have any other ideas or research priorities that may pertain to sediments?

 

The Ecological Risk IG has sparked a lively discussion on research questions for that IG and I look forward to a similar response on sediments!

Hi Tamara,
I would fully agree that topic number 1 in this list is worthy of a SETAC focus topic meeting or workshop. I think it would be important to emphasize not just the best methods to get a number but the best methods in terms of how the number obtained relates to organism response. I think incorporated into this could also be the discussion of sediment spiking methods that has already be started within SEDAG. I would also like to hear from those working on updating the draft USEPA AVS/SEM method.

The sediment spiking question applies also to topic number 3 on the list above which I also think is a very important topic. I would be interested to know how much work has been done on sediment guideline improvement/development in the last decade and where the data gaps are.

I would like to propose a session/workshop to discuss sediment guideline development methodologies, sediment guideline uses and limitations, and application guidance (site specifics, field to lab comparisons etc.). This is like a subset of the idea 3 expressed above.

Cheers,
Trudy

1. What are the best methods to measure bioavailable/freely-dissolved/chemical activity of organic chemicals and metals in environmental media?

Just as an FYI, the PWG (Pyrethroid Working Group) has quite a lot of experience here, using the solid phase microextraction (SPME) method to measure bioavailable fractions of pyrethroids in water/sediment studies. There are a number of SEDIG members that are also PWG members (myself included), so this is certainly a topic of potential interest for a workshop/focus meeting.

Hi Tamara,

thank you for starting this survey.

4. Do you have any other ideas or research priorities that may pertain to sediments?

Is there any progress ongoing, how we could harmonize the OECD and EPA sediment guidance for a unique RA?
Best regards, Daniel
