Estimation Programs Interface

In a study by Andersson et al. [30], the possibilities to use quantitative structure-activity relationship (QSAR) models to predict physical chemical and ecotoxico-logical properties of approximately 200 different plastic additives have been assessed. Physical chemical properties were predicted with the U.S. Environmental Protection Agency Estimation Program Interface (EPI) Suite, Version 3.20. Aquatic ecotoxicity data were calculated by QSAR models in the Toxicity Estimation Software Tool (T.E.S.T.), version 3.3, from U.S. Environmental Protection Agency, as described by Rahmberg et al. [31]. To evaluate the applicability of the QSAR-based characterization factors, they were compared to experiment-based characterization factors for the same substances taken from the USEtox organics database [32], This was done for 39 plastic additives for which experiment-based characterization factors were already available.

The standard deviation is expected to be about 0.3 log units, corresponding to a factor of 2. For a narrower class of substances, using the equations in Table 7.1, the standard deviation is expected to fall to about 0.2 log units or a factor of 1.6. The Syracuse Research Corporation offers an estimation nethod WSKOWWIN as part of its Estimation Program Interface for Windows (EPI/WIN) details are available at the web site http //syr-res.com/interskow/epi.htm. 

Methods for the prediction of the physicochemical properties of molecules are summarized in Chapter 3. The SRC methods form an integrated package run through an integrated estimation programs interface (EPIWIN). Because they are very widely used, some aspects of their function are discussed further below.
