Dear Colleague, We are writing to bring to your attention a session of potential interest to you at the December 3-7, 2012 AGU meeting in San Francisco. As detailed in the abstract below, our session will be an exploration of the impact of contaminants on biogeochemical processes in human-impacted ecosystems. We hope that you can contribute to stimulating discussion in this session that will engage speakers with interdisciplinary expertise on the impacts of development. We have invited an exciting array of speakers including Daniel Bain (University of Pittsburgh), Brian Bergamaschi (USGS), Thomas Cuffney (USGS) and Emma Rosi-Marshall (Cary Institute of Ecosystem Studies). Abstracts must be submitted by August 8, 2012 23:59 UT (fallmeeting.agu.org/2012/). Please share this announcement with students and colleagues who may wish to contribute a presentation. If you have any questions feel free to contact either of us. Sincerely, Joe Bushey and Tim Vadas [email protected]; [email protected] Session link: http://fallmeeting.agu.org/2012/session-search/single/impacts-of-urban-contaminants-on-biogeochemical-processes/
B032: Impacts of Urban Contaminants on Biogeochemical Processes Urban stream syndrome describes the typically degraded conditions in urban aquatic environments, including increased loading of trace metals, inorganic anions (e.g., chloride), pharmaceuticals, and endocrine disrupting compounds. Investigations typically focus on acute and/or chronic toxicity thresholds, yet many of these compounds are not regulated or are below thresholds but still exhibit adverse effects on ecosystems. Sub-lethal impacts on biogeochemical processes are critical to assess. This symposium will highlight laboratory or field-based research examining impacts of single or mixed contaminants other than nutrients (e.g. N, P) on biogeochemical cycles, microbial activity, and community composition. Co-Organizers: Joseph Bushey, Civil and Environmental Engineering, University of Connecticut, Storrs, CT 06269, [email protected]; Timothy Vadas, Civil and Environmental Engineering, University Of Connecticut, Storrs, CT 06269, [email protected].
