Rationale for reliability incl. deficiencies:
other: Even if not GLP, there is no guideline for this type of test. This paper provides an example of the contamination of kraft paper mill wastewater by salicylic acid, and its removal through the the treatment systems.

Applicant's summary and conclusion

Conclusions:
Salicylic acid does not appear to be a problem in the waste waters from paper mills.
Even if it is not absolutely clear that "-" means "not detected", the low levels observed at stage 1 and 2 in Mill A, and the decrease between stage 1 and stage 2, tends to demonstrate that salicylic acid is present at low levels and that it is apparently well removed by the waste water treatment process.
Executive summary:

Wastewaters from two kraft paper mills in Georgia (US) were sampled at various points in the waste treatment systems to extract and identify specific chemical components.
