EC number: 925-259-5
CAS number: 140921-24-0
PNEC freshwater sediment:
K_(susp-water) = 959
RHO_(susp) = 1150
Conversion factor (wwt -> dwt) = 4.6
PNEC freshwater sediment
= (K_(susp-water)/RHO_(susp)) * PNEC_water *
= (959/1150)* 0.029 * 1000
= 24.2 mg/kg wwt
= 111.2 mg/kg dwt
PNEC marine water sediment:
PNEC marine water sediment
= (K_(susp-water)/RHO_(susp)) * PNEC_marine
water * 1000
= (959/1150)* 0.0029 * 1000
= 2.42 mg/kg wwt
= 11.1 mg/kg dwt
K_(soil-water) = 1.15E+03
RHO_(soil) = 1700
Conversion factor (wwt -> dwt) = 1.13
= (K_(soil-water)/RHO_(soil))* PNEC_water *
= (1.15E+03/1700)* 0.029 * 1000
= 19.6 mg/kg wwt
= 22.2 mg/kg dwt
Algae is the most sensitive species to the
