Expanded uncertainty with a coverage factor of 2 (μk=2) in parentheses.

Between-bottle standard deviation (sd) on the second row.

*1:The concentrations will be monitored 1 year after the date of last availability.

*2:The values are below quantifiable detection limit (QDL); therefore please use these values as a guide.

*3:The nitrite value is entered as a reference value because an increasing trend (0.004 ± 0.002 μmol/kg nitrite per year) has been confirmed.

*4:A separate expiration date is allocated for this nitrite value because of the increasing trend (0.004 ± 0.002 μmol/kg nitrite per year).
