| Three types of pesticide degradation are microbial, chemical, and photodegradation. |
| Understanding the mechanisms by which photodegradation occurs may lead to more polymers that have environmental and medical applications. |
| The flash photolysis technique can be used to determine the time of evolution of the products of photodegradation. |
| However, the mechanism of porphyrin photodegradation can be complex and differs in solution and in biological media. |
| Riboflavin photodegradation and photosensitizing effects are highly dependent on oxygen and ascorbate concentrations. |
| All operations were carried out on ice under a dim green safe light to prevent photodegradation, isomerization and structural changes of the pigments. |
