Results and discussion

Any other information on results incl. tables

Since this material is not volatile, the only potential photolytic reaction that needs to be considered is direct photolysis at the earth's surface. Direct photolysis is not possible because this material does not have a chromophore absorbing at a wavelength of 290 nm or above, and the presence of such a chromophore is a necessary condition for photolysis.

Applicant's summary and conclusion

Validity criteria fulfilled:
not applicable
Conclusions:
Direct photolysis of sodium formate is not possible, since the substance does not have a chromophore absorbing at a wavelength of 290 nm or above, which is a prerequisite for photolysis.
Executive summary:

Since this material is not volatile, the only potential photolytic reaction that needs to be considered is direct photolysis at the earth's surface. An expert judgement is available based on reliable handbook data for sodium formate, which describes that direct photolysis is not possible because this material does not have a chromophore absorbing at a wavelength of 290 nm or above, and the presence of such a chromophore is a necessary condition for photolysis (Lymanet al., 1990). Phototransformation testing would there be redundant for sodium formate.
