Many emerging contaminants have not undergone thorough ecotoxicity testing\, since they have only recently come to the attention of scientist s\, government\, and the public. Earthworm toxicity tests play a key role in determining the risk of a contaminant to the health of soil organisms. Metabolomics is emerging as a useful tool for assessing toxicity\, since i t provides a snapshot of the physiological state of an organism and yields a greater depth of knowledge than traditional endpoints. This thesis uses standard earthworm toxicity testing methods combined with targeted gas ch romatography-mass spectrometry (GC-MS) metabolomics to assess the toxicity to earthworms of three emerging contaminants (triclosan\, methyltriclosan \, and metformin) present in biosolids.\n\nEveryone in the ºÚÁϲ»´òìÈ communit y is welcome to attend a PhD oral defense. Please join us in celebrating t he accomplishments of our PhD candidates.\n\n \n\n \n DTSTART:20180321T153000Z DTEND:20180321T153000Z LOCATION:MS2-022\, Macdonald-Stewart Building\, CA\, QC\, St Anne de Bellev ue\, H9X 3V9\, 21111 Lakeshore Road SUMMARY:PhD Oral Defense: Assessment of emerging organic contaminant toxici ty to the earthworm Eisenia fetida using GC-MS metabolomics URL:/macdonald/channels/event/phd-oral-defense-assessm ent-emerging-organic-contaminant-toxicity-earthworm-eisenia-fetida-using-g c-285323 END:VEVENT END:VCALENDAR
