Sodium Fluoroacetate (compound 1080) - Lincoln University ...

A standard uptake and decay curve was not seen (Fig. 7). With the MDL in place, no 1080
appeared on Day 7 or Day 38; with the MDL removed, 1080 was detected on both of these
days at very low concentrations (Table 2). All levels of 1080 detected, regardless of plant or
sample day, were at very low concentrations.

Figure 7. Maximum 1080 concentrations (ppb) seen from puha tissue samples over duration of the study
When graphed with rainfall (Fig. 8) (mm/day) no pattern occurred between rainfall and 1080
concentrations seen from puha, as the rainfall events occurred after sampling. However,
plant tissue samples were not collected every day, and had daily sampling occurred a pattern
may have been observed.
