| However, the mechanism of porphyrin photodegradation can be complex and differs in solution and in biological media. |
| All operations were carried out on ice under a dim green safe light to prevent photodegradation, isomerization and structural changes of the pigments. |
| The following qualifications refer to all types of degradation, including for instance biodegradation and photodegradation. |
| Three types of pesticide degradation are microbial, chemical, and photodegradation. |
| Riboflavin photodegradation and photosensitizing effects are highly dependent on oxygen and ascorbate concentrations. |
| However, some level of continued photodegradation down to the biphenyl ether could also likely occur. |
