Results and discussion

Any other information on results incl. tables

RS-Freetext:
In the study the abiotic degradation of DEHP through OH-
radicals was determined. Under the test conditions
(aerosol-smog-chamber-technique) a mean tropospheric
lifetime of ca. 1 day was analysed with kOH=1,5x10-11 cm3/s.

Degradation in % (for indirect photolysis): ca. 100 after 1 day(s)
