WebWhile MHBMA and DHBMA have been found in smokers and nonsmokers, THBMA has not been previously detected in humans. In the present work, an isotope dilution HPLC-ESI - -MS/MS methodology was developed and employed to quantify THBMA in urine of known smokers and nonsmokers (19-27 per group). Web14 Feb 2014 · Bis-BDMA was formed in a dose-dependent manner in urine of rats exposed to 0–200 p.p.m. BD by inhalation, although it was a minor metabolite (1%) as compared with DHBMA (47%) and THBMA (37%). In humans, DHBMA was the most abundant BD-mercapturic acid excreted (93%), followed by THBMA (5%) and MHBMA (2%), whereas no …
