The objective of setting criteria for persistence in the environment is to avoid situations where the substance will accumulate to greater and greater amounts over time.

Finally, based on the estimated substance properties and in combination with the defined criteria for persistence, bioaccumulation potential and LRTP, SVHC and borderline chemicals are identified within the organic non-ionic compounds of the REACH database.

Of the infections that cleared, 42 (71%) recurred, 27 (46%) of which again met criteria for persistence.

Consistent with such fluctuation around the limit of assay sensitivity is our finding that the majority of cleared infections under the two-week definition subsequently recurred and met criteria for persistence.

In order to successfully use metadata from different systems in a heterogeneous environment for data integration, systems that serve as sources of truth would have to meet the above criteria for persistence, and historical data and metadata, such as those typically stored in an EDW would have to be readily available.

None of these geometric mean values exceeds the criterion for persistence (60 days) in water for classification as a POP under the SC or as persistent (40 days) under EC Regulation No. 1107/2009.

Since the half-life of CPY in water does not exceed the criterion for persistence in water (see the 'Water' section), it is unlikely that LRT in water would be a significant issue.

Canada and the USA recognised the need for elimination of persistent toxic substances from the Great Lakes and introduced the concept of half-life of a substance in water as a measure (criterion) for persistence [31, 50]: "Half-life means the time required for the concentration of a substance to diminish to one-half of its original value in a lake or water body".

This, along with its short half-life in water (4.7 days at pH 7), supports the conclusion of Mackay et al. [15] that CPYO is less persistent than the parent compound, CPY, and therefore does not trigger the criterion for persistence under the SC and EC Regulation No. 1107/2009.

The authors stated that DAS28-CRP remission criteria allowed for persistence of pain in more than 10% of patients, whereas there were very few complaints of pain among patients in ACR/EULAR remission.
