Abstract Advanced oxidation processes (AOPs) can degrade heavy metal complexes in wastewater to improve the removal efficiency of metals. However, the influences of AOP treatments on toxicity induced by metal complexes are not well understood. This study compared the toxicity induced by EDTA-copper (Cu) after UV/persulfate (PS) and UV/H2O2 treatments on luminescent bacteria and human HepG2 cells. The results showed that EDTA-Cu complexes decreased Cu toxicity in luminescent bacteria but increase...

Abstract Haloacetonitriles (HANs) are nitrogenous disinfection byproducts (N-DBPs) detected in drinking water that have high toxicity and are a high risk to human health. The cytotoxicity and genotoxicity as well as the oxidative stress of five HANs, namely chloroacetonitrile (CAN), dichloroacetonitrile (DCAN), trichloroacetonitrile (TCAN), bromoacetonitrile (BAN), and dibromoacetonitrile (DBAN) on a hepatoma cell line (HepG2) were determined by single, binary or ternary exposure. The median eff...

Abstract Pharmaceuticals are increasingly detected in environmental matrices, but information on their trophic transfer in aquatic food webs is insufficient. This study investigated the bioaccumulation and trophic transfer of 23 pharmaceuticals in Taihu Lake, China. Pharmaceutical concentrations were analyzed in surface water, sediments and 14 aquatic species, including plankton, invertebrates and fish collected from the lake. The median concentrations of the detected pharmaceuticals ranged from...

The individual and combined biochemical responses of erythromycin and ketoconazole have been examined in an organism representative of the aquatic environment, crucian carp (Carassius auratus). The possible interactions between erythromycin and ketoconazole were investigated on the bioaccumulation and the expression of biotransformation enzymes 7-ethoxyresorufin-O-deethylase (EROD) and glutathione S-transferase (GST), and an antioxidant defense enzyme superoxide dismutase (SOD) in fish tissues. ...

The tissue distribution, bioconcentration, metabolism and biological effects of the antifungal medication ketoconazole were investigated in fish, crucian carp (Carassius auratus) were exposed to a series of nominal concentrations (0.2, 2 and 20 μg/L) for 14 days. The ultra-high performance liquid chromatography tandem triple quadrupole mass spectroscopy (UPLC/MS/MS) analysis was used to determine the bioconcentration of ketoconazole and its metabolites in fish. The highest tissue concentration o...

Hydrophobic Fe3O4@SiO2@C18 magnetic nanoparticles (MNPs) composites were synthesized. Then it was characterized by TEM, SEM and FT-IR. In combination with HPLC-FLD/VWD, it was applied to extract extract 8 typical PAHs in water. The impact of extraction and analytical conditions on the extraction efficiency were studied in detail. The result shows that Fe3O4@SiO2@C18 MNPs has good extraction effect on the target PAHs. On optimum conditions, the limits of detection, linearity range and relative st...

ABSTRACTHealth risk assessments of As, Cr, Pb, and Zn in air in China were carried out from a national perspective. Concentrations of the four metals in air were gathered from published literature. Health risk assessment models recommended by the U.S. Environmental Protection Agency (USEPA) were applied to quantitatively characterize risk values of the metals by considering different age groups. Results showed that the atmospheric metal concentrations in most regions of China were lower than the...

Occurrence of five estrogens, including estrone (E1), 17β-estradiol (E2), estriol (E3), 17α-ethynylestradiol (EE2) and bisphenol A (BPA) in water, sediment and biota in Northern Taihu Lake, were investigated and their ecological risk was evaluated. Most of the target estrogens were widely distributed in the eight studied sampling sites, and their levels showed a regional trend of Gong Bay > Meiliang Bay > Zhushan Bay. The average concentrations of E1, E2, E3, EE2 and BPA ranged from 3.86 to 64.4...

A probabilistic carcinogenic risk assessment of atmospheric polycyclic aromatic hydrocarbons (PAHs) in four big cities (Beijing, Shanghai, Guangzhou, Xiamen) of China was carried out. PAHs levels in these cities were collected from published literatures and converted into BaP equivalent (BaPeq) concentrations. The health risk assessment models recommended by US EPA were applied to quantitatively characterize the health risk values of PAHs. Monte Carlo simulation and sensitivity analysis were app...

Adsorption behavior of 17α-ethinylestradiol (EE2) in northern Taihu Lake sediment was analyzed by using batch equilibrium experiment. Freundlich isotherm could describe the adsorption thermodynamic behavior of EE2 in sediment. Sediment organic matter (SOM) contents had important impacts on the adsorption capacity for EE2. The pH values also influenced the adsorption capacity for EE2. Increase of pH value could decrease the EE2 adsorption, which might be due to the electrostatic repulsion between...
