ANNEX IIIU.K.METHODS FOR THE EVALUATION OF THE ENVIRONMENTAL HAZARDS OF PREPARATIONS IN ACCORDANCE WITH ARTICLE 7

PART BU.K.Concentration limits to be used for the evaluation of environmental hazards

I.For the aquatic environmentU.K.

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 substance(s) present whose classification is also shown.

[F1Table 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 C n ≥ 25 % 2,5 % ≤ C n < 25 %
R52-53 C n ≥ 25 %

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

For preparations containing substances with a lower LC 50 or EC 50 value than 0,00001 mg/l, the corresponding concentration limits are calculated accordingly (in factor 10 intervals).]
