Upcoming Sediment Meetings at SETAC Vancouver

Posted By Trudy Watson-Leung, Monday, October 27, 2014

Hello Everyone,

Stuart Simpson (Chair of the SETAC SEDAG) and Paul Sibley and Chris Ingersoll (Members of the SETAC SEDAG Steering Committee) would like to highlight some of the sediment meetings and sediment sessions planned for the upcoming meeting of SETAC at the Vancouver Convention Center.

 

Please contact the individuals listed below for additional information regarding these planned events.

 

1. SETAC SEDAG

When: Tuesday November 11 from 7 to 8 am in Room 116/117

Discussion topics: (1) Introduce new members of the SEDAG steering committee and future plans for the SEDAG; (2) Draft revisions planned to USEPA/ASTM freshwater sediment toxicity methods; (3) Development of a sediment-spiking toxicity database. Point of contact: Paul Sibley (psibley@uoguelph.ca)

2.  ASTM Subcommittee E50.47 on Biological Fate and Effects

When: Wednesday November 12 from 7 to 8:30 am in Room 116/117

Discussion topics: (1) Status of E50.47 standards; (2) Draft revisions planned to USEPA/ASTM freshwater sediment toxicity methods; (3) Methods for culturing and conducting chronic toxicity tests with the midge Chironomus dilutus. Point of contact: Chris Ingersoll (cingersoll@usgs.gov; see attached agenda)

3. Methods for conducting whole-sediment toxicity tests with the amphipod Leptocheirus plumulosus

When: Thursday November 13 from 2 to 4 pm in Room 306 (refreshments courtesy Maxxam Analytics)

Discussion topics: Challenges facing labs conducting chronic Leptocheirus 28-d sediment toxicity tests with spiked sediments for pesticide registrations. The meeting will provide an opportunity for interested parties to share information. Discussions will include potential reasons for why the test has been difficult to conduct and ideas about how to make the test more successful and easier to perform by multiple laboratories. Point of contact: Curtis Eickhoff (ceickhoff@maxxam.ca)

4.  Refining Methods for Conducting Laboratory Whole-Sediment Toxicity Tests (platform session and poster session). Point of contact: Christian Picard (cpicard@smithers.com)

When: Platform session, Thursday November 13 from 8 to 11:15 am in Ballroom C

1.     649: Inter-lab testing of Hyalella azteca water and sediment methods. 1: Background and overview of the 42-d survival, growth and reproduction test, T. Norberg-King

2.     650: Inter-lab testing of Hyalella azteca water and sediment methods. 2: Results from 10- to 42-d tests conducted with water-only and sediment substrates, C. Ivey

3.     651: Measuring up: how does a Hyalella azteca reproduction test conducted entirely in sediment compare?, L. Taylor

4.     652: Feasibility of using Centroptilum triangulifer larvae in sediment toxicity tests, J. Lazorchak

5.     653: Chronic sediment toxicity testing with the estuarine amphipod Leptocheirus plumulosus; trials and tribulations, M. Bradley

Hardness tolerance of different strains of Hyalella azteca

Posted By Trudy Watson-Leung, Tuesday, November 19, 2013
I was wondering if anyone has done an assessment of hardness tolerance of the common laboratory (US and Canada, as per Major et al 2013) strain of Hyalella azteca?
