Conclusion on classification

The following relevant key results are currently available for deriving the classification of the pure target substance for the environment:

- marine fish Cyprinodon variegatus: 96h-LC50: >32 mg/L

- marine copepod Acartia tonsa: 48h-EC50: 1503 mg/L

- marine phytoplankton Skeletonema costatum: 72h-ErC50 = 74.1 mg/L; NOErC: 32 mg/L

- Readily biodegradable based on an OECD 306 study

- Log Kow: << 4 (low potential for bioaccumulation)

However, as the target substance is an aqueous solution with 45 to 86% water, these values need to be multiplied at least by a factor of 1.8

Acute (short-term) aquatic hazard

As the acute E(L)C50 values are >1 mg/L, the substance does not need to be classified for this hazard category according to Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP).

 

Chronic (long-term) aquatic hazard

One chronic value is available, for phytoplancton. As there are no chronic values available for fish and crustacea, the chronic classification has to be determined with the available chronic data for phytoplanctone based on CLP Table 4.1.0 (b)(ii), as the substance is readily biodegradable, and with the available acute data for fish and invertebrates based on CLP Table 4.1.0 (b) (iii). The most stringent classification is valid;

 

- CLP Table 4.1.0 (b)(ii): As the NOErC is > 1 mg/L, the substance does not need to be classified based on this key result.

- CLP Table 4.1.0 (b)(iii): As the substance is readily biodegradable and has low potential for bioaccumulation, the substance does not need to be classified.

 

It is therefore concluded that based on the currently available data, the substance does not need to be classified for environmental hazards according to CLP.
