PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

Based on comparison to the screening criteria, DTPA-Fe(NH4)2 is not B or vB. Based on comparison to the criteria in Annex XIII, the substance is also not T. Available data from screening tests do not allow concluding that the assessed substance is not a P / vP. Based on expected similar behavior and fate compared to EDTA (read across) and the lack of biodegradability, DTPA-Fe(NH4)2 is slowly biodegradable in surface water under specific environmental conditions. In addition, due to high water solubility and low adsorption, DTPA will eventually leach to ground- and surface waters and not accumulate in soil. Due to pH fluctuations in surface water, moderate substitution rates and the combined photodegradation and biodegradation, all DTPA salts will eventually disappear from surface water.

DTPA-Fe(NH4)2 is not considered a PBT or vPvB substance.
