“…Previous studies found that JP of B. calyciflorus was prolonged in the treatments with bromate [27], fenitrothion [28], and dieldrin [29]. In the present study, under the algal densities of 1.0 × 10 6 cells/mL, compared with the control, JP was prolonged at 30-75 mg/L TBM (p<0.01), and both RP and LS were shortened at 30-75 mg/L TBM (p<0.01).…”

One of the most adopted methods to inactivate coronaviruses (COVID-19) is to use chlorine-containing disinfectants. Unfortunately, as a result, large amounts of disinfection byproducts (DBPs) containing chlorine can enter the river through the sewage treatment system [1]. It is even worse that chlorination is still the most widely applied disinfection method to inactivate pathogenic microorganisms for water treatment. Trihalomethanes (THMs), e.g. trichloromethane (TCM), bromodichloromethane

“…This activity in the CAS effluent combined with soluble nutriments could be the reason for the strong stimulation of the rotifer reproduction observed with this sample. Huang et al (2012) showed that dieldrin and 17β-estradiol at concentrations as low as 1 ng/L were prone to cause a shortening in the duration of embryonic development and an increase in the reproductive period, post-reproductive period, net reproduction rate, generation time, and life expectancy at hatching of B. calyciflorus.…”

A mixture of urban and hospital effluents (50% v/v) was evaluated for ecotoxicity with an advanced bioassay battery. Mixed effluents were tested before any treatment, after biological treatment alone, and after biological treatment followed by a tertiary ozonation (15 mg O3/L). Laying a high value on the continuance of organisms' fitness, essential to preserve a healthy receiving ecosystem, the main objective of this study was to combine normalized bioassays with newly developed in vivo and in vitro tests in order to assess alteration of embryo development, growth and reproduction, as well as genotoxic effects in aquatic organisms exposed to complex wastewater effluents. Comparison of the bioassays sensitivity was considered. Contrary to the lack of toxicity observed with normalized ecotoxicity tests, endpoints measured on zebrafish embryos such as developmental abnormalities and genotoxicity demonstrated a residual toxicity in wastewater both after a biological treatment followed or not by a tertiary O3 treatment. However, the ozonation step allowed to alleviate the residual endocrine disrupting potential measure in the biologically treated effluent. This study shows that normalized bioassays are not sensitive enough for the ecotoxicological evaluation of wastewaters and that there is a great need for the development of suitable sensitive bioassays in order to characterize properly the possible residual toxicity of treated effluents.
