Additional information

PNEC freshwater sediment:

K_(susp-water) = 0.9

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_freshwater sediment

= (K_(susp-water) / RHO_(susp)) * PNEC_water * 1000

= (0.9/1150) * 0.0222 * 1000

= 0.01737 mg/kg wwt

= 0.07992 mg/kg dw

 

PNEC marine water sediment:

K_(susp-water) = 0.9

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marine water sediment

= (K_(susp-water) / RHO_(susp)) * PNEC_marine water * 1000

= (0.9/1150) * 0.00222 * 1000

= 0.001737 mg/kg wwt

= 0.007992 mg/kg dw

 

PNEC soil:

K_(soil-water) = 0.203

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

PNEC_soil

= (K_(soil-water) / RHO_(soil)) * PNEC_water * 1000

= (0.000119) * 0.0222 * 1000

= 0.00265 mg/kg wwt

= 0.002996 mg/kg dw

 

The K_(susp-water) and K_(soil-water) values were calculated using EUSES 2.1.2.

Conclusion on classification

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be readily biodegradable. The most sensitive test for the aquatic compartment was the toxicity test to algae. The test to marine algae revealed an EC50 value of 0.5 mg/L, but it is important to note that the marine test is likely to overestimate the toxicity to KMPS triple salt, because in salt water oxidation of KMPS triple salt generates chlorine from sodium chloride, increasing the biocidal activity of test solutions. Based on the behaviour of KMPS triple salt in sea water and the marginal ErC50-values obtained, classification and labelling with Acute env. tox. cat. 1, H400, according to Regulation (EC) No 1272/2008 (CLP), respectively, does not apply. The test with freshwater algae revealed an EC50 of >1mg/L. Based on these results, the substance is not classified for short-term (acute) aquatic toxicity.

Chronic data is available for all three trophic levels, with the most stringent outcome of a 37-day NOEC in Cyprinodon variegatus of 0.222 mg/L, a Cat 3 (H412: harmful to aquatic life with long lasting effects) is warranted for KMPS (triple salt) according to Regulation (EC) No 1272/2008 (CLP), as amended for the twelth time in Regulation (EC) No 2019/521.
