Factors Controlling the Distribution of Contaminant Metals inConnecticut Coastal Harbors
Since 2001, Werth Center for Coastal and Marine Studies student and faculty researchers have collected and analyzed the chemical and physical characteristics of surface sediments from fourteen Connecticut harbor and river estuaries. The goal of this research was to conduct a high spatial resolution sampling within each harbor to determine factors contributing to variations in sediment composition and metal contamination. Harbors examined in this study represent a range of demographics, land use, urbanization and industrialization, and are geographically located in eastern Long Island Sound.
Sediment metal concentrations (iron, copper, zinc, arsenic, cadmium) were determined using flame or graphite furnace atomic absorption spectrometry following acid digestion using US EPA Method 3050B. Mercury analyses were performed on sediment directly using a DMA-80 mercury analyzer.
Measured sediment metal concentrations within each harbor are highly variable, and for many harbors, crustal abundances of contaminant metals are exceeded by 5-20 fold of natural abundances. Sediment organic carbon content (loss on ignition), mean grain-size and iron content are strongly correlated with metal concentrations in all harbors/rivers studied. Knowledge of the spatial variation of contaminant metals within harbors is important for assessing current and future impacts to commercial activities and living marine resources.
Vincent T. Breslin, Professor of the Environment, Geography and Marine Sciences at Southern Connecticut State University (SCSU), teaches undergraduate courses in Marine Studies, Environmental Studies, the SCSU Honors College, and the graduate Environmental Education MS program. Dr. Breslin received the J. Phillip Smith Award for Outstanding Teaching at SCSU and was elected a SENCER Leadership Fellow for his work in science and civic engagement. He is co-founder and coordinator of the Connecticut State Colleges and Universities Werth Center for Coastal and Marine Studies that promotes Marine Science Study especially having to do with the Long Island Sound environment. Dr. Breslin’s laboratory research and field-based studies examine the biogeochemical behavior of contaminant metals in coastal sediments. His research studies have been important in understanding the spatial distribution of contaminant metals in Connecticut harbors and the potential accumulation of these metals in living marine resources.
he New Haven section is pleased to host the Third Annual Student Research Symposium on Saturday April 28th, 2018 at Quinnipiac University.
Time: 8:15 AM to 2:30 PM
The symposium program will feature both oral and poster presentations given from undergraduate students conducting research at local universities within New Haven County. Presentation topics will cover research in fields such as pharmaceuticals, nanotechnology, analytical chemistry, forensics, biochemistry, polymer science, green chemistry and sustainability.
Awards will be given for best oral and best poster presentations
A campus map can be found on the (Free parking is available on campus)
Registration and Abstract Submission:
Symposium attendance is FREE and open to all local students, academic faculty, and industry professionals. Lunch and coffee breaks will be provided.
We ask all interested attendees to pre-register for the event. Attendees who sign up on or before Friday April 13th will be eligible for the raffle drawing at the end of the day!
Event Schedule (Tentative):
8.15: Registration opens and breakfast

Need suggestions for designing your poster? Watch this video created by ACS Webinars on the basics of impactful scientific posters.
Oral presentations should be prepared for a presentation length of 20 minutes: 15 minutes to cover all material and 5 minutes for questions.
Presentation rooms will come equipped with a projector, screen, microphone and laser pointer. Please arrive at your assigned room prior to the start of the session to ensure compatibility with the projector.
