Toxic effects of disinfection by-products on Pseudokirchneriella subcapitata and co-cultured algae community

Jinjie Li et al.

Summary: The widespread use of disinfectants due to the COVID-19 pandemic can lead to increased levels of disinfection by-products (DBPs) in surface water, posing ecological risks. This study assessed the acute toxicity of haloacetic acids and halophenols DBPs on Pseudokirchneriella subcapitata and evaluated their impact on co-cultured algae communities. The results showed that exposure to DBPs significantly reduced the photosynthetic pigments of Pseudokirchneriella subcapitata and increased MDA content and antioxidant enzyme activity. The ecological risk assessment indicated medium to high risks for TBAA, 2,4-DBP, and 2,6-DBP. However, high-risk DBPs had minimal effect on the community structure of co-cultured algae, while low-risk DBPs had a greater impact and promoted the growth of cyanobacteria, potentially causing new ecological risks.

Effect of chlorine disinfectant influx on biological sewage treatment process under the COVID-19 pandemic: Performance, mechanisms and implications

Chenyuan Dang et al.

Summary: This study investigated the effect of chlorine on the microbiome and microbial chlorine resistance in the activated sludge of the aerobic treatment process. The results showed that chlorine had a dose-dependent negative impact on nitrogen/COD removal in the aerobic treatment process, and the microbial community in activated sludge was influenced by both chlorine dose and interaction time. Some microorganisms were able to survive in chlorinated conditions by up-regulating the expression of chlorine resistance genes (CRGs).

Chlorination of phenol, bisphenol A, and methylparaben in the presence of bromide: Kinetic simulation and formation of brominated aromatic byproducts

Jing Zhang et al.

Summary: The rising sea level and seawater intrusion have caused an increase in bromide levels in coastal cities. Adding bromide improves the degradation of phenol, bisphenol A, and methylparaben by chlorine. The reactions between bromide, chlorine, and phenols are described by a kinetic model. The rate constants of active bromine with phenols are higher than those of chlorine, resulting in a bromide enhancement effect. The model accurately predicts the change in oxidant concentration over time. Developing techniques to remove bromide and phenolic components is important for controlling the formation of toxic brominated aromatic byproducts.

Effects on rumen microbiome and milk quality of dairy cows fed a grass silage-based diet supplemented with the macroalga Asparagopsis taxiformis

Sophie J. Krizsan et al.

Summary: The effects of adding Asparagopsis taxiformis to the diets of dairy cows on rumen microbiome and milk quality were investigated. The results showed that the addition of Asparagopsis taxiformis significantly reduced methane production and altered rumen fermentation parameters. Milk quality was also affected, with an increase in bromine and iodine concentrations.

Responses of aquatic organisms downstream from WWTPs to disinfectants and their by-products during the COVID-19 pandemic, Wuhan

Chuan Wang et al.

Summary: The outbreak of COVID-19 has resulted in the widespread use of chlorinated disinfectants in cities. The impact of these disinfectants on water ecosystems and aquatic organisms was investigated in the Hanjiang, Fuhe, and Qinglinghe Rivers in Wuhan. The study found that despite the use of chlorine-containing disinfectants, the density of aquatic organisms in the water sources was not harmed.

Occurrence of Iodophenols in Aquatic Environments and the Deiodination of Organic Iodine with Ferrate(VI)

Xian-Shi Wang et al.

Summary: This study identified the presence of milligram per liter levels of iodophenols and micrograms per liter to milligrams per liter levels of iodide and total organic iodine in river water, wastewater treatment plant effluent, and medical wastewater. Oxidation experiments showed that ferrate could oxidize iodide, total organic iodine, and iodophenols, leading to their deiodination. Pre-oxidation with ferrate was effective in inhibiting the formation of iodinated disinfection by-products.

Occurrence and Distribution of Disinfection Byproducts in Domestic Wastewater Effluent, Tap Water, and Surface Water during the SARS-CoV-2 Pandemic in China

Zhigang Li et al.

Summary: The study investigated the occurrence and distribution of disinfection byproducts (DBPs) in domestic wastewater effluent, tap water, and surface water in China. Results showed that DBP concentrations were higher in wastewater effluents than tap water and surface water, with haloacetic acids (HAAs) and trihalomethanes (THMs) being the most dominant categories. Additionally, the study revealed that HAAs in wastewater effluents had higher risk quotient values for green algae.

Formation of disinfection byproducts during chlorination of mixed nitrogenous compounds in swimming pools

Fangyuan Peng et al.

Summary: Studies have shown that tryptophan has the highest DBP formation potential during chlorination of mixed precursors in swimming pools; urea and ammonia restrain the formation of C-DBPs but promote the formation of more toxic N-DBPs; under all experimental conditions, C-DBP yields were significantly higher than N-DBP yields.

Full insights into the roles of pH on hydroxylation of aromatic acids/bases and toxicity evaluation

Zexiu An et al.

Summary: This study investigated the mechanistic and kinetic insights into the roles of pH on the hydroxylation of five aromatic acids and bases in UV/H2O2 process. The reactivity of center dot OH towards the species is positively correlated with electron-donating effect of substituents, contributing to the positively pH-dependent reactivity of aromatic acids and bases. The optimal degradation pH values are around 5.5 to 7.5.

Pool water disinfection by ozone-bromine treatment: Assessing the disinfectant efficacy and the occurrence and in vitro toxicity of brominated disinfection by-products

Fatima El-Athman et al.

Summary: The study demonstrates that the disinfection efficacy of hypobromous acid is comparable to hypochlorous acid, but may not always meet the disinfection level required by the German DIN standards in certain situations. The formation of brominated disinfection by-products primarily depends on bromide concentration, with no significant impact on in vitro cytotoxicity or genotoxicity.

Chlorination decreases acute toxicity of iodophenols through the formation of iodate and chlorinated aliphatic disinfection byproducts

Xian-Shi Wang et al.

Summary: HOCl was found to effectively convert iodinated phenolic disinfection byproducts into non-toxic iodate and less toxic chlorinated aliphatic DBPs, reducing the acute toxicity of water samples containing iodophenols. Further investigations on the transformation and toxicity alteration of emerging DBPs during chlorination/booster chlorination are warranted due to the widespread use of chlorine as a disinfectant.

Toxicity of 17 Disinfection By-products to Different Trophic Levels of Aquatic Organisms: Ecological Risks and Mechanisms

Huijun Cui et al.

Summary: Different types of DBPs have specific toxicities to different trophic levels of organisms, with potential mechanisms for toxicity to microalgae involving damage to photosystems and oxidative stress. Multiple bioassays with organisms at different trophic levels are necessary to determine the ecotoxicity of DBPs. The ecological risks of DBPs are high, as indicated by risk quotients greater than 1.0 for all organisms in wastewater effluents.
