Professor Frank Dorman, Associate Professor, Biochemistry & Molecular Biology, Penn State University, introduces the field of environmental forensics and describes how environmental exposure to harmful compounds can be linked to an increase in human disease state. For example, chemotherapeutic drugs can enter waste water and consequently drinking water, resulting in human exposure to a harmful low dose of the drugs. Hear how highly sensitive mass spectrometry technology can be used to detect and monitor low levels of emerging compounds of interest in human samples.
