| Three types of pesticide degradation are microbial, chemical, and photodegradation. |
| However, some level of continued photodegradation down to the biphenyl ether could also likely occur. |
| Understanding the mechanisms by which photodegradation occurs may lead to more polymers that have environmental and medical applications. |
| The photodegradation which considerably speed up the visible skin ageing increases also a lot the risk of development of cutaneous neoplasm. |
| The flash photolysis technique can be used to determine the time of evolution of the products of photodegradation. |
| All operations were carried out on ice under a dim green safe light to prevent photodegradation, isomerization and structural changes of the pigments. |
