| Research Abstract |
Fifty-three groundwater samples were collected from springs, confined and unconfined aquifers in Tokyo. Thirteen species of perfluorinated carbons (PFCs), as well as pharmaceuticals, were analyzed. High concentrations of PFCs were detected in springs and unconfined aquifers, but PFCs were also detected in confined aquifers, which indicated the wide-spread contamination of groundwaters in Tokyo by PFCs.
