The file contains three files in comma separated values (.csv) format. “Reyes_EHP_Phthalates_US_metabolites.csv” contains information about the National Health and Nutrition Examination Survey (NHANES) metabolite code names along with Tolerable Daily Intake (TDI), molecular weight of the parent phthalate, molecular weight of the metabolite, and names and abbreviations of the corresponding metabolites and phthalates. “Reyes_EHP_Phthalates_US_MCR.csv” contains the following information: • Data on the surveyed individuals from the original NHANES data files that includes • Identifying information for individual; • Demographic information used in defining the creatinine levels and in investigating sub populations based on age, gender, ethnicity; • Concentration of phthalate metabolites and creatinine in urine. • Calculated values for each individual; • Daily intake of each of the six phthalate; • Hazard Quotients associated with each phthalate’s daily intake; • Values of Hazard Index and the Maximum Cumulative Ratio. “Reyes_EHP_Phthalates_US_MCR_definitions.csv” and the definitions and units of the fields in “Reyes_EHP_Phthalates_US_MCR.csv”. This dataset is associated with the following publication: Reyes, J., and P. Price. An analysis of cumulative risks based on biomonitoring data for six phthalates using the Maximum Cumulative Ratio. ENVIRONMENT INTERNATIONAL. Elsevier B.V., Amsterdam, NETHERLANDS, 112: 77-84, (2018).

An Excel file including: raw data, data dictionary, and all final data sets. A PDF containing detailed equations for calculating the daily dose using the creatinine correction and UFR, figures comparing the HI between the creatinine correction and UFR, figures and tables comparing temporal trends in the MCR between the HI and potency-weighted approach, tables describing frequency of participants by cycle, temporal limit of detection by metabolite, tolerable daily intakes by phthalate, Group designation of the MCR, complete regression equations used in the regression analysis, comparison of Group counts by creatinine correction and UFR, and relative potency factors by phthalate.

The Chemical and Product Categories database (CPCat) catalogs the use of over 40,000 chemicals and their presence in different consumer products. The chemical use information is compiled from multiple sources while product information is gathered from publicly available Material Safety Data Sheets (MSDS). EPA researchers are evaluating the possibility of expanding the database with additional product and use information.
