Environmental Toxicology Laboratory submits Testimony to the EPA Expert Panel on WTC Contaminant Monitoring. On November 15, 2004 Dr. Robert Jaffe submitted a proposal, to the WTC Expert Panel, for inclusion of the Tetramitus Particle Assay for consideration as one of the tests to be used in monitoring for WTC Dust Contamination.

The issues of whole particle toxicity and the possible synergistic effect of mixtures were raised.

Environmental Toxicology Laboratory Tests Deutsche Bank WTC Contaminated Dust Samples Dr. Nancy Adams, of the EPA Department of Homeland Security/Consequences and Decontamination Division, has provided ETL with Deutsche Bank, WTC contaminated dust samples in order to examine toxicity results using the Tetramitus Growth Inhibition and Glaucoma chattoni Swimming Behavior Assays.

The complete report and a short version have been submitted on 23 February 2005. A feasibility study is proposed which would demonstrate the utility of the Glaucoma Swimming Behavior Assay for monitoring worker exposure during the upcoming Deutsche Bank Deconstruction.

An additional study is proposed which would confirm DNA Damage as the mechanism of action for the growth inhibition of Tetramitus flagellates exposed to particle suspensions prepared from the Deutsche Bank Dust Samples.
