| Thus, it is difficult to derive meaningful estimates of exposure to individual congeners or congener groups. |
| North American populations of Hypomesus transpacificus, a congener of H. pretiosus, spend the entire life-cycle in freshwater. |
| The habits of the house cricket are nocturnal, like those of its congener of the fields. |
| The consultation concentrated its deliberations on 2, 3, 7, 8-TCDD as this was the most toxic congener and was carcinogenic in animals. |
| However, the congener composition differed from the original PBB mixture, indicating partial degradation of the PBB residue in the soil samples. |
| Tannins are one form of congener, so red wine will be worse for you than white wine. |
