Lanthanum oxide

Lanthanum fluoride

Hydrolysis

Waived based on low water solubility

No data

Biodegradation

Waived based on inorganic nature

Bioaccumulation

No data

Low potential for bioaccumulation

Low potential for bioaccumulation

Low potential for bioaccumulation

Adsorption/desorption

Waived as technically not feasible due to low water solubility

Koc = 5480283

Koc,des = 358213

Strong potential to adsorption to soil

No data

 

Based on the similar physico-chemical properties of the reaction mass and its constituents (i.e.inorganic nature, very low to low water solubility), one can expect similar fate and behaviour in the environment for the four substances.
