Summary

This study shows that a decrease in the TOX content of chlorinated dilute solutions of aquatic humic substances could be observed under neutral or basic conditions after storage and/or sulfite addition. The mutagenicity tests performed directly on chlorinated samples of AHS concentrated solutions showed that the addition of sulfite could also reduce significantly the mutagenicity. The results obtained with partially or fully dechlorinated samples of AHS dilute solutions showed that only a complete dechlorination treatment could decrease the TOX level and the mutagenic activity of XAD extracts.
