Description of key information

The overall persistence for l-Glutamic acid, N-coco acyl derivs., monosodium salts (Sodium Cocoyl glutamate), oxidized is 27 days using the default emission scenario of the level III multimedia model. The overall persistence using different release scenarios is provided in the following section :

The estimation persistence is based on a standard release scenario emitting equal amounts to soil, water, and air.  A in-depth assessment may utilize a release scenario that is more representative of an individual chemical's life cycle. The seven release scenarios mentioned below are based on a more realistic total release of 300 kg/hr to the environment. Since the fugacity model is linear, the percent in each compartment does not change based on the total release to the environment, but only on the relative amount released to air, water, and soil.

The following table provides the percent estimated in each environmental compartment using different release scenarios. The media (water, soil, and sediment) the chemical is expected to be found in predominantly (the predominant compartment) is underlined. The color of each estimate indicates if the EPA criteria have been exceeded in that specific medium. Therefore, by determining the color of the underline value in each row, the persistence ranking for each different scenario can be compared directly to the default persistence value,P, estimated. The overall persistence, Po(days), calculated for each release scenario is also provided.
