My understanding is it's based on pure chemical and the impact of the pure chemical, and not on the mixture and not on the amount used. If you had a fertilizer that needs very little used but it's a bit more toxic versus one that's not quite as toxic but needs a vast quantity to be used, that is not taken into account in CEPA, in my understanding. In terms of life-cycle analysis, it would be taken into account.
