Additional information

PNEC sediment

 

Ksusp-water: 0.295 (according to EUSES)

RHOsusp: 1150 kg/m3(according to the CSA Guidance document equation R10-2)

 

PNECsediment-freshwater= (Ksusp-water/RHOsusp) * PNECfreshwater*1000

PNECsediment-freshwater= (0.295/1150) * 0.025 mg/L * 1000

PNECsediment-freshwater= 0.0064 mg/kg wwt

 

PNECsediment-freshwater= 0.0295 mg/kg dwt (factor 4.6)

 

PNECsediment-marine water= (Ksusp-water/RHOsusp) * PNECmarine-water*1000

PNECsediment-marine water= (0.295/1150) * 0.0025 mg/L * 1000

PNECsediment-marine water= 0.00064 mg/kg wwt.

 

PNECsediment-marine water= 0.00295 mg/kg dwt (factor 4.6)

PNEC soil

 

Ksoil-water: 0.979 (according to EUSES v. 2.1.2)

RHOsoil: 1150 kg/m3(according to the CSA Guidance document, chapter R.10, May 2008, equation R10-2)

 

PNECsoil= (Ksoil-water/RHOsoil) * PNECfreshwater*1000

PNECsoil= (0.979/1150) * 0.025 mg/L * 1000

PNECsoil= 0.021 mg/kg dwt

PNECsoil= 0.021 mg/kg soil dwt

Conclusion on classification

Based on the results obtained, Sodium ethylenesulphonate was not classified and labelled for environmental hazards according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP).
