“…Post exposure, changes in cell morphology were evaluated using a microscope before the cells were rinsed with L-15/ex solution following measurement of cytotoxicity by AlamarBlue (Invitrogen), 5carboxyfluorescein diacetate acetoxy methyl ester (CFDA-AM, Thermo Fisher Scientific), and Neutral Red assays performed as described elsewhere. 26 Fluorescence intensity was measured using a Spectramax Gemini M microplate reader at excitation/emission wavelengths of 532/590, 485/535, and 532/680 nm for AlamarBlue, CFDA-AM, and Neutral Red, respectively. Fluorescence values were normalized against the controls and presented as percentage of cell viability.…”

“…The generation of reactive oxygen species (ROS) during exposure and after 48 h of exposure to WEEE was measured by using the 6carboxy-2′7′-dichlorofluorescein diacetate (DCFH-DA) assay according to methods previously presented elsewhere. 26 Single-point fluorescence measurements were periodically made over 18 h, following direct WEEE exposure and kinetically measured 3 h following 48 h of exposure to WEEE at excitation/emission wavelengths of 485/535 nm using a Spectramax Gemini M microplate reader. Data was represented as the generation of ROS.…”

Manual dismantling, shredding, and mechanical grinding of waste from electrical and electronic equipment (WEEE) at recycling facilities inevitably lead to the accidental formation and release of both coarse and fine particle aerosols, primarily into the ambient air. Since diffuse emissions to air of such WEEE particles are not regulated, their dispersion from the recycling plants into the adjacent environment is possible. The aim of this interdisciplinary project was to collect and characterize airborne WEEE particles smaller than 1 μm generated at a Nordic open waste recycling facility from a particle concentration, shape, and bulk and surface composition perspective. Since dispersed airborne particles eventually may reach rivers, lakes, and possibly oceans, the aim was also to assess whether such particles may pose any adverse effects on aquatic organisms. The results show that WEEE particles only exerted a weak tendency toward cytotoxic effects on fish gill cell lines, although the exposure resulted in ROS formation that may induce adverse effects. On the contrary, the WEEE particles were toxic toward the crustacean zooplankter Daphnia magna, showing strong effects on survival of the animals in a concentration-dependent way.

“…By adding appropriate agents or substances to the wastewater, the concentration and/or toxicity of nano-ZnO in the wastewater can be reduced, thus reducing the adverse effects of nano-ZnO on the BNR treatment unit of the wastewater. For example, Khort and his colleagues found that adding natural organic matter mainly composed of fulvic and humic acid to the ZnO NPs solution could adsorb ZnO NPs to form colloids with higher stability, which helps aggregation and sedimentation [96]. It has also been reported that the addition of HA can reduce the concentration of zinc ions released by ZnO NPs, thereby alleviating the toxicity of ZnO NPs to bacteria [97].…”

Engineered nano-ZnO is extensively utilized in both production and daily life, leading to its inevitable entry into the wastewater treatment system through various pathways. Nitrogen removal microorganisms in wastewater treatment systems are highly susceptible to environmental impacts. The antibacterial properties of nano-ZnO can impede the biological nitrogen removal (BNR) process and adversely affect the nitrogen removal performance. A comprehensive understanding of the inhibitory effect and mechanism of nano-ZnO on the BNR process is crucial in devising appropriate countermeasures to ensure optimal nitrogen removal performance. This review provides an overview of the sources of nano-ZnO in the environment, its impact on the BNR process, and the inhibition mechanism, and proposes potential methods that can mitigate the inhibitory effect of nano-ZnO. Additionally, future prospects are also discussed. This review serves as a foundation for a deeper understanding of the inhibition of engineered nano-ZnO on the BNR process and aids in guiding efforts to maintain the nitrogen removal performance in the presence of engineered nano-ZnO.
