For her honors thesis, biology major Hannah Fink  ’09 (Whitehall, Pa.) is putting together lab studies that will  measure the toxicity of the herbicide atrazine. Fink, who is also a  member of the College’s women’s soccer team, is working with Nancy  Waters, associate professor of biology, and Steve Mylon,  assistant professor of chemistry.
Atrazine is a common herbicide used in corn production that previous  studies have shown to be an endocrine disruptor at low concentrations.  My thesis will establish a method to measure atrazine and desethyl atrazine, one of atrazine’s  degradation byproducts, for use in ecological toxicity studies on  Hyalella azteca, a tiny crustacean related to the crayfish. I am looking  at the fate of the two chemicals in the experimental aquatic system as  well as the reproductive and developmental effects on the crustaceans.
My honors thesis is a crucial first step in preparing me for a career  in aquatic toxicology. Next fall, I will be in the Ph.D. program in  toxicology at University of Maryland. My purpose in pursuing a doctoral  degree is with the long-term objective of conducting meaningful and  novel research in either an academic setting or for the Environmental  Protection Agency that will positively impact the health of the human  race and the environment we live in. I am interested in studying the  effects of emerging contaminants on aquatic systems and the method of  toxicity for such organisms.
Since I am currently working with an aquatic system, I am learning  methodology and techniques that can be applied to my graduate studies  and future career. The analytical chemistry skills that I have acquired  and am utilizing will also be a huge asset when entering a graduate  program. In addition, conducting an honors thesis is beneficial in  helping me to advance my writing skills and preparing me for a Ph.D.  thesis.
Working with my thesis adviser, Professor Waters, has been a  wonderful experience. She has been instrumental in helping me work  through my initial experimental ideas in order to design a project that  would be feasible given the time constraints of an undergraduate thesis.  While Professor Waters is always available to provide advice and  guidance on the project, she also allows me the independence I need to  conduct the research. She is an inspiring person to work for and very  knowledgeable in her field.
As a secondary adviser, Professor Mylon  assists me in all of the chemistry aspects of my research. His knowledge  and assistance in these chemical techniques has been a tremendous asset  for my project. It has truly been a pleasure to work with him on this  project as well as my previous EXCEL Scholars research.
