dinitrotoluene mixture has a cancer slop factor, why don the individual isomers use the same slope factor?
It was determined for this website that the IRIS toxicological profile did not adequately address this issue. • Do the fish tissue SLs apply to wet-weight or dry-weight data? The fish SLs represent the concentration that can be consumed at the rate indicated in the Technical Background Document. Therefore, wet or dry weight is not an inherent assumption of the SL numbers. Rather, users of the Table should consider whether their population of interest is more likely to consume the fish using a preparation method that is better simulated by a wet or dry weight. (For example, consumption of raw or fried fish would be more likely represented by wet weight, whereas consumption of smoked or dried fish might be better represented by dry weight.) In other words, the use of a site-specific sample as wet or dry weight should be governed by its representativeness for the population of interest. • Why do some of the numbers on the SL Table exceed a million parts per million (1E+06 mg/kg)? That’s n
