The aquatic environment
1. The concentration limits fixed in the following tables, expressed as a weight/weight percentage, determine the classification of the preparation in relation to the individual concentration of the substances present whose classification is also shown.
Table 1a
Acute aquatic toxicity and long term adverse effects
Classification of the substance | Classification of the preparation |
---|
| N, R50-53 | N, R51-53 | R52-53 |
---|
N, R50-53 | see Table 1b | see Table 1b | see Table 1b |
N, R51-53 | | Cn ≥ 25% | 2.5% ≤ Cn < 25% |
R52-53 | | | Cn ≥ 25% |
For preparations containing a substance classified with N, R50-53, the concentration limits and the resulting classification given in Table 1b are applicable.

Acute aquatic toxicity and long-term adverse effects of substances very toxic to the aquatic environment
LC50 or EC50 value (“L(E)C50”) of substance classified as N, R50-53 (mg/l) | Classification of the preparation |

0.1 < L(E)C50 ≤ 1 | Cn ≥ 25% | 2.5% ≤ Cn < 25% | 0.25% ≤ Cn < 2.5% |
0.01 < L(E)C50 ≤ 0.1 | Cn ≥ 2.5% | 0.25% ≤ Cn < 2.5% | 0.025% ≤ Cn < 0.25% |
0.001 < L(E)C50 ≤ 0.01 | Cn ≥ 0.25% | 0.025% ≤ Cn < 0.25% | 0.0025% ≤ Cn < 0.025% |
0.0001 < L(E)C50 ≤ 0.001 | Cn ≥ 0.025% | 0.0025% ≤ Cn < 0.025% | 0.00025% ≤ Cn < 0.0025% |
0.00001 < L(E)C50 ≤ 0.0001 | Cn ≥ 0.0025% | 0.00025% ≤ Cn < 0.0025% | 0.000025% ≤ Cn < 0.00025% |
For preparations containing substances with a lower LC50 or EC50 value than 0.00001 mg/l, the corresponding concentration limits are calculated accordingly (in factor 10 intervals).
