Description Nowadays there is a continuously increasing attention for the treatment of recalcitrant compounds present in
water and wastewater due to their toxicity on both human health and the environment. Advanced oxidation processes (AOPs) are found to be effective for the degradation of recalcitrant compounds by increasing biodegradability and reducing toxicity. The present review focuses on the detoxification aspects of AOPs with special
emphasis on arsenic toxicity. Different bioassays employing bacteria, invertebrates, algae, plants, and fish have
been critically reviewed in this article as a valuable tool for assessing the toxicity as well as biodegradability of
the industrial wastewater post AOP treatment. Various toxicity tests employed during AOP treatment of wastewater with high toxicity revealed that AOPs are effective for reducing their toxicity significantly. These processes
are also effective to reduce arsenic toxicity by oxidizing arsenite to arsenate. By-products formed during AOP
treatment of wastewater are also found more toxic than its parent compound. Thus, toxicity tests are essential
for AOP treated wastewater before its disposal.
