In urine, OPFR metabolites have been detected, but the median concentrations of the diaryl and dialkyl phosphates remained mostly below the quantification limit. Ranges of concentrations of dialkyl and diaryl phosphates are shown in Table 4. In the study of Schindler et al. [302, 303], the detection frequency was highest for BCEP (50%), followed by DPP (30%), BCPP (12%), and DBP (3%). Di-w-cresyl and di-/7-cresyl phosphate were not found in any sample, probably due to lower exposure in the indoor environment. Reemtsma et al. [304] found also monoaryl and alkyl phosphates in human urine, of which the monobutyl phosphate was the...

Materials used in the atomic energy industry are liable to decomposition by radiation the y-radiation products from tributyl phosphate, for example, include dibutyl and monobutyl phosphate and small quantities of hydrogen, methane and ethane. 

It is obvious that during separation the organic phase is under the effect of intensive y, P, and a radiation fields. Therefore, radiation resistance is a very important issue. TBP decomposes to products dibutyl phosphate (G 0.2 pmol J ), monobutyl phosphate (0.02 pmol J ), and gaseous hydrogen (0.15 pmol J ). In addition to these main components some minor products, butane, butene, C1-C3 hydrocarbons, butanol, and phosphoric esters are also observed. Dibutyl phosphate is suggested to form in solvated electron reaction... 

The degradation of TBP may primarily form butanol and butyl nitrate. The butanol formed via the hydrolysis of TBP, monobutyl phosphate (H2MBP) and dibutyl phosphate (HDBP), may subsequently undergo nitration to form butyl nitrate. Alternatively, butanol may undergo oxidation to yield carboxylic acids and gases (carbon dioxide and nitrogen monoxide).
