Overview of the assessment procedure to identify
PMT/vPvM substances.
First, if the substance contains an identifiable organic structure,
it is assessed for persistence, with possible conclusions being very
persistent (vP), persistent (P), Potential P/vP++ (very likely to
meet the P or vP criteria), Potential P/vP (not readily/inherently
biodegradable, but unknown if P/vP), and Not P. Unless the substance
is “Not P” or there is "insufficient data"
because of
“no data or conflicting data” for persistency, it is
assessed for mobility (with conclusions being very mobile (vM), mobile
(M), potentially M/vM, and “not M”). Unless the substance
is “not M” or there is "insufficient data"
because of
“no or conflicting data” for mobility, it is assessed
for toxicity. Final conclusions can be “vPvM & PMT”,
vPvM, PMT, “Potential PMT/vPvM”, PM, “Not PMT/vPvM”,
or “insufficient data”. More information on the persistence
and mobility assessment can be found in Figures 4 and 9.
