| 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. |
| However, some level of continued photodegradation down to the biphenyl ether could also likely occur. |
| Three types of pesticide degradation are microbial, chemical, and photodegradation. |
| The photodegradation which considerably speed up the visible skin ageing increases also a lot the risk of development of cutaneous neoplasm. |
| Even when indirect photolysis could occur with a photosensitizing agent, there is no clear evidence of lindane photodegradation. |
