Professor Frank Dorman describes environmental forensics and how environmental exposure can be linked to an increase in human disease state. Chemotherapeutic drugs enter waste water either via improper disposal by patients or hospitals.

Detection of such drugs can be monitored using highly sensitive mass spectrometry and methodology for this is currently being developed. Interview filmed by SelectScience at ASMS 2014.
