Screening and estimating of toxicity formation with photobacterium bioassay during chlorine disinfection of wastewater

Ecotoxicological screening of reclaimed disinfected wastewater by Vibrio fischeri bioassay after a chlorination–dechlorination process

“…Wang et al [25] have also reported a decrease in the toxicity of disinfected wastewater when ammonia nitrogen increased from 2 to 30 mg/L. However, Abdullah et al [26] found no correlation between DBPs and nitrogen in Malaysian drinking water, mainly due to the absence of ammonium in almost all samples.…”

Toxicity assessment of chlorinated secondary effluents by theVibrio fischeribioluminescence assay

“…Sorlini and Collivignarelli [18] reported similar results in artificial lakes and rivers. Wang et al [19] have also reported a decrease in the toxicity of disinfected wastewater when ammonia nitrogen increased from 2 to 30 mg/L.…”

Achieving biodegradability enhancement and acute biotoxicity removal through the treatment of pharmaceutical wastewater using a combined internal electrolysis and ultrasonic irradiation technology

“…The principle of the method quantifies the decrease in light emission from the bioluminescent bacteria, photo-bacterium phosphoreum, resulting from exposure to pollutants. The extent of luminescence inhibition after 5 min of exposure was standardized into an equivalent concentration of Zn 2+ , which was used to express the degree of the pollutants' effects on the test bacteria [16]. Thus, greater luminescence inhibition corresponded to a higher equivalent concentration of Zn 2+ .…”
