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.
