An egg abandoned by a tern (a seabird) after the egg failed to hatch. The research is a partnership between Diana Aga, UB chemistry professor, and Alicia Pérez-Fuentetaja, SUNY Buffalo State biology professor and research scientist at SUNY Buffalo State’s Great Lakes Center.

The abandoned tern eggs that scientists are studying were collected in Western New York by a biologist with the New York State Department of Environmental Conservation.

With a glass pipette in hand, UB chemistry PhD student Steven Travis carefully weighs out 1 gram of egg white from an abandoned tern egg. This task is one of many steps in preparing the sample for chemical analysis.

UB chemistry PhD student Steven Travis measures the volume of a chemical standard, a solution that contains known amounts of a certain chemical. Chemical standards act as a reference, enabling scientists to accurately quantify traces of chemicals found in analytical testing.

A vortex mixer is used to shake vials holding egg whites or egg yolks, along with a liquid solvent that extracts chemicals from the egg. This process helps to separate the biological content of samples (the whites and yolks) from the chemicals (flame retardants and pesticides) the scientists are hoping to analyze.

From mother to child?

UB chemists are studying how chemicals such as flame retardants and pesticides accumulate in the local ecosystem, including in fish, birds and bird eggs. One goal is to learn whether chemicals can pass from mother birds to their young, to eggs. Photos: Meredith Forrest Kulwicki
