Description of key information
Additional information
Mecoprop-P n-octyl ester hydrolyses rapidly in natural water. Therefore, the hydrolysis product Mecoprop-P acid (MCPP-P acid) was used for further risk assessment of Mecoprop-P n-octyl ester in the environment.
Mecoprop-P acid (MCPP-P acid) has a low sorption potential to soil and sediment, and a moderate migration potential to groundwater.
The Henrys law constant of Mecoprop-P acid (MCPP-P acid) is 5.74E-05 Pa*m3/mol. Therefore, Mecoprop-P acid (MCPP-P acid) is considered nonvolatile from the aqueous phase, and no potential for long-range transport is given.
The distribution of Mecoprop-P acid (MCPP-P acid) in a "unit world" was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for Mecoprop-P acid (MCPP-P acid) is water with 99.98 %, followed by soil and sediment with 0.008 % and air with 0.002 %, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
