In a series of three experiments, the researchers subcutaneously injected mice with TBBPA
, triclosan, or both; the study used doses much larger than typical human exposures.
Mimo ze TBBPA
jest stosowany na olbrzymia skale na calym swiecie, jego produkcja i zastosowanie nie podlegaja monitoringowi czy ograniczeniom.
IPC director of environmental policy Fern Abrams "strongly suggests" that the subcommittee begin to gather data on the use, difficulties in replacing and of TBBPA
in materials used in electronics, Newton added.
Although early studies were focused on the use of triple quadrupole mass spectrometers, the high selectivity of ion-trap MS was applied for the determination of TBBPA
in sediment and sewage sludge scanning the range from m/z 145-543 after LC separation .
