comparison study is needed prior to any substantial work on statistical analysis of the benzene regulatory (i.e. IPHS) database. Exposure Simulations Data analysis and report preparation continues for the interior redecoration painting and small part degreasing simulations summarized in the previous progress report. Optimal use of the data from the simulations depends to a large degree on information about the time trends and changes in composition for paint solvents and solvents used in degreasing. To date, the availability of compositional information has been limited due to lagging of science and technology development on product quality controls. Although information does exist for at least for some time periods and for some relevant materials, access has been severely restricted. As described above, efforts to assemble composition information will continue. Questionnaire Administration and Analysis The CC/DP exposure assessment process, which has been described in previous reports, is again outlined in Figure 2. To date, 8300 EA questionnaires have been collected, 8000 entered into the database, 7600 have been validated and 7300 have had preliminary EA completed. The difference between the total number validated and EA reviewed generally reflects EA questionnaires in process, some excluded cases, and shortfalls in documentation previously described. Translations Progress on translations continues on track with a total of 19,749 out of 24,183 work history entries having been updated during the last 6 months. (A worker with a single jobexposure scenano = 1 work history entry; a worker with 2 job-exposure scenarios = 2 work history entries, etc.) 5 SHELL-MCCLURG-059318
