Additional information


Key study: estimated by calculation: Koc = 2.738. It is concluded that sodium trichloroacetate showed a low soil sorption, so it is concluded that sodium trichloroacetateshowed a low soil sorption, in particular to the predominately negatively charged soil colloids, because of its physicochemical properties (high water solubility, strong dissociation in aqueous solution).

Henry's Law constant:

Key study: estimated by calculation (EPI Suite v3.20, EPA). The estimated Henry's Law constant for sodium trichloroacetate is 24x10-9atm.m3/mole at 25 ºC.

Distribution modelling:

Percent distribution in media: Air: 0.422%; Water: 50.1%; Soil: 49.4%; Sediment: 0.0973% Persistence time: 1110 h = 46 d. Half lifes; Air: 100,000 h = 4167 d =11 a; Water: 1440 h = 60 d; Soil: 2880 h = 120 d; Sediment: 13,000 h = 542 d; Volatilization from water; Half life vom Model river: 33,220 h = 1384 d; from Model Lake: 362,500 h = 15,104 d = 41 years.
