Transport evaluation

Uncertainty on tlie other hand, represents lack of knowledge about factors such as adverse effects or contaminant levels which may be reduced with additional study. Generally, risk assessments carry several categories of uncertainly, and each merits consideration. Measurement micertainty refers to tlie usual eiTor tliat accompanies scientific measurements—standard statistical teclmiques can often be used to express measurement micertainty. A substantial aniomit of uncertainty is often inlierent in enviromiiental sampling, and assessments should address tliese micertainties. There are likewise uncertainties associated with tlie use of scientific models, e.g., dose-response models, and models of environmental fate and transport. Evaluation of model uncertainty would consider tlie scientific basis for the model and available empirical validation.

Mode/container size The quantity of material that can be released is dependent on the size of the shipping container, which in turn is dictated by the mode of transport. Evaluating the container size enables a comparison of the extent of the potential consequences between different modes as well as different transportation amounts for the same mode.

Bioanalytical sample analysis by LC/MS/MS remains a rate-limiting step in many ADME processes, including transporter evaluation. The number of injection samples and MS run time can escalate rapidly and depend on whether compounds are tested in duplicate or triplicate and the number of points generated for a standard curve. For example, if one compound is evaluated in parental and MDRl-transfected cell lines in triplicate in both directions, 12 samples are generated from both apical and basolateral compartments. Add in an eight-point standard curve (1 500 nM), dose solutions, wash injections in-between triplicates, and approximately 58 injection samples per compound would result If each injection were approximately 3 min per run, then each... 

One recent and detailed study sponsored by the U.S. Department of Transportation evaluated the effectiveness and practicality of four different devices that are either already available on the market or are at various stages of marketing (Carroll, 2005 Dinges et aL, 2005). The evaluation included two driver-based devices and two vehicle-based devices ... 

Unfortunately, the lack of integrity of the 1,1-6FDA-DIA homopolymer film prohibited transport evaluation in the uncrosslinked state. Crosslinking improved mechanical strength and allowed for transport analysis. As shown in Table I, the crosslinked 1,1- DA-DIA homopolymer shows decreased permeabilities and increased selectivities when compared to the blends with lower 1,1-6FDA-DIA contents.
