Results are in parts per billion by volume(ppbv) <br /> 3. U indicates the constituent is less than the laboratory method detection limit(MDL). <br /> 4. 1 indicates the result is greater than the laboratory MDL and less than the practical quantitation limit. <br /> 5. 1 indicates surrogate recovery was outside of the limit. <br /> 6. NA indicates not applicable. <br /> Table 2 <br /> FR0766H <br /> 1 of 1 May 2014 <br />
