Software: Computer Algorithms Implemented:

            Sielken & Associates develops software primarily for internal and client use and does not for distribute software for sales purposes.

Exposure Assessment Tools:

8. Quantitative cancer risks and contaminant standards for multipathway and multimedia exposures.
                       OFFSITE
   
    
9. Distributional characterizations of the cancer risks and contaminant standards for populations and subpopulations exposed via multiple pathways to a single medium.
                       ONSITE
   
    
10. PRObabilistic Methodology for Improving Solvent Exposure Assessment is the interface that assists the user in organizing the input data and that subsequently activates the Sielken, Inc., DistGEN software in order to determine how the distributions of measured and assumed input values affect the resulting uptake distributions for particular populations and subpopulations.  DistGEN utilizes Monte Carlo simulation in order to determine the uptake distributions.

11. Maximum Likelihood Imputation Procedure for Imputing Single-Serving Residue Concentration Distributions from Composite Samples.  MaxLIP is a two-step procedure that uses maximum likelihood estimation techniques and Monte Carlo simulation to estimate the distribution of residue concentrations in single units from a database of composite residue concentration values.
