Table 4.
Spearman’s correlation coefficients (r) for the relationship of Pb ovary concentration to lead dose during exposure in different groups
| Exposure period | Depuration period | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| 3 | 6 | 12 | 15 | 18 | 24 | 3 | 6 | 12 | |
| r | 0.74*** | 0.62*** | 0.60*** | 0.28 | 0.66*** | 0.61*** | 0.48 | 0.17 | 0.01 |
| p | ns | 0.0008 | 0.0001 | ns | 0.005 | 0.007 | ns | ns | ns |
p expresses the level of significant differences for gonadal lead concentration between female groups exposed to different metal doses in different periods of the experiment (multiple comparisons Kruskall–Wallis test)
***p < 0.001
