The results of toxicity experiments showed that R32 would not cause acute, chronic, cumulative and genetical toxicity effect on algae, Allium cepa, Zebra, fish and mice before it absorbed Cr. The recovery and sterilization measurement in routine water treatment could reduce most of the R32 in effluent. This may ensure that the effluent would not cause any ill effect on all kinds of biology in the environment after it was discharged into the river.

With it, simple, mechanistically significant and highly predictive QSAR models were developed. These QSARs successfully model and predict the short-term phytotoxicity of substituted phenols involved both polar narcosis and bio-reactivity, the growth inhibition toxicity to Saccharomyces cerevisiae of substituted nitrobenzenes with mixed mechanisms of toxic action based on electrophilicity and the growth inhibition toxicity to Saccharomyces cerevisiae of large set of substituted benzenes with complex molecular structures and multiple mechanisms of action.
