Taking into account the instability of sodiumdithionite under environmental conditions (decomposition/hydrolysis to sulfite and sulfate) and its physicochemial properties which make adsorption to soil unlikely, the derivation of a PNEC for the terrestrial compartment is not feasible/appropriate.
into account the instability of sodiumdithionite under environmental
conditions (decomposition to sulfite and sulfate) and its physicochemial
properties which make adsorption to soil unlikely, the derivation of a
PNEC for the terrestrial compartment is not feasible/appropriate:
to rapid oxidation of sodium dithionite, no relevant test design and
toxicity data can be generated
to the lack of a relevant adsorption
coefficient for dithionites to soil, the equilibrium partitioning method
for deriving a PNECterrestrial is not applicable
into account the industrial use, exposure pathways and environmental
fate of sodium dithionite, long-term exposure of sediment organisms to
this substance can be excluded.
there is no need to derive a PNECterrestrial for
