Additional information
NEC freshwater sediment:
K_(susp-water) = 1.87E3 = 1870
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment = (K_(susp-water)/ RHO_(susp))*PNEC_water * 1000
= (1870/1150)* 0.0872 *1000
= 141.7948 mg/kg wwt
= 652.256 mg/kg dwt
PNEC marine water sediment:
K_(susp-water) = 1.87E3 = 1870
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine water sediment = (K_(susp-water)/ RHO_(susp))*PNEC_marine water* 1000
= (1870/1150)* 0.00872 * 1000
= 14.17948 mg/kg wwt
= 65.2256 mg/kg dwt
PNEC soil:
K_(soil-water) = 2.24E3 = 2240
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil = (K_(soil-water)/ RHO_(soil))*PNEC_water * 1000
= (2240/1700)* 0.0872 * 1000
= 114.8989 mg/kg wwt
= 129.8357 mg/kg dwt
Conclusion on classification
Acute aquatic toxicity:
Fish were the most sensitive species in acute aquatic toxicity tests with SIKA Hardener LI, according to EU method C.1 and OECD guideline 203, resulting in a 96-hour EC50 of 87.2 mg/L. Based on acute aquatic toxicity results obtained, SIKA Hardener LI was not classified and labelled for acute aquatic toxicity according to Directive 67/548/EC (DSD) and Regulation (EC) No 1272/2008 (CLP).
Chronic toxicity:
SIKA Hardener LI was tested in an aquatic toxicity test with algae, according EU-method C.3 and OECD guideline 201. The 72-hour EC50 for growth rate was 180.4 mg/L and the 72-hour NOEC 25 mg/L. SIKA Hardener LI was shown to be ready biodegradable failing the 10-day window and hydrolysis was rapid, with a half-life of 99 min at 25°C. Thus, the substance has to be classiffied with R52/53 according to Directive 67/548/EEC (DSD) and as environmental chronic toxic cat. 3 according to Regulation (EC) No 1272/2008 (CLP). This classification is in line with the data and the classification of both hydrolysis products (for details see IUCLID5 sections 6.1.1, 6.1.3 and 6.1.5).
