1. For substances and tested mixtures:
L(E)C50 ≤ 1mg/1 where L(E)C50 is either fish 96hr LC50, crustacea 48hr EC LC50 or aquatic plant 72 or 96hr ErC50.

2. If data for a mixture are not available, use bridging principles (see 4.1.3.4). Exit EPA disclaimer

3. If bridging principles do not apply,

(a) For mixtures with classified ingredients: The summation method (see 4.1.3.5.5) Exit EPA disclaimer reveals:
  • [Concentration of Acute 1] × M > 25% where M is a multiplying factor (see 4.1.3.5.5.5). Exit EPA disclaimer
(b) For mixtures with tested ingredients:
The additivity formula (see 4.1.3.5.2 and 4.1.3.5.3) Exit EPA disclaimer reveals:
  • L(E)C50 ≤ 1mg/l.
(c) For mixtures with both classified and tested ingredients: The combined additivity formula and summation method (see 4.1.3.5.2 to 4.1.3.5.5.3) Exit EPA disclaimer reveal:
  • Concentration of Acute 1 × M > 25%.

4. For mixtures with no usable information for one or more relevant ingredients, classify using the available information and add the statement: “x percent of the mixture consists of component(s) of unknown hazards to the aquatic environment”.
