ND, not detected. Although variability in total mercury across samples was large, organic mercury was consistently absent.
a
Determined for only samples 6–11.
b
Samples were digested normally with sodium hydroxide and cysteine and then collected on silver traps to detect the presence of mercury.
c
Samples were dissolved in 10% nitric acid and then collected on silver traps to detect the presence of mercury.
