Which standard should be followed for calculating the toxicity of mixed media?

If that’s the case, there’s no need to calculate. I just don’t want to be so conservative; I just want to find a basis for it

In accordance with TSG D0001-2009: When the medium is a mixture, the acute toxicity of the mixture should be determined using the weighted average method, based on the composition proportions of the toxic chemicals and their acute toxicity values. Subsequently, the toxicity hazard level of the mixture is determined based on the highest toxicity hazard level among them.

Hello! Is there a reference clause for this calculation method? Is there a specific explanation?
