TLDR
These studies suggest relative high acute toxicity of ZnO NPs (in the low mg/l levels) to environmental species, although this toxicity is highly dependent on test species, physico-chemical properties of the material, and test methods.About:

Generation and Detection of Reactive Oxygen Species in Photocatalysis
Yoshio Nosaka,Atsuko Y. Nosaka +1 more
TL;DR: The detection methods and generation mechanisms of the intrinsic reactive oxygen species (ROS) in photocatalysis were surveyed comprehensively and the major photocatalyst used in heterogeneous photocatalytic systems was found to be TiO2.

Toxicity of Ag, CuO and ZnO nanoparticles to selected environmentally relevant test organisms and mammalian cells in vitro: a critical review
Olesja Bondarenko,Katre Juganson,Katre Juganson,Angela Ivask,Kaja Kasemets,Monika Mortimer,Monika Mortimer,Anne Kahru +7 more
TL;DR: The toxic range of all the three metal-containing NPs to target- and non-target organisms overlaps, indicating that the leaching of biocidal NPs from consumer products should be addressed.
Journal ArticleDOI
Review on the improvement of the photocatalytic and antibacterial activities of ZnO
TL;DR: In this paper, a review of the application of photocatalytic degradation and the antibacterial properties of zinc oxide (ZnO) nanomaterials is reviewed, and the main methods that improve antibacterial activities are coating inorganic or organic antimicrobial agents, doping ZnO, and tuning the size, morphological characteristics, and concentration of ZnOs.

Nanoparticle colloidal stability in cell culture media and impact on cellular interactions
Thomas Moore,Laura Rodriguez-Lorenzo,Vera Hirsch,Sandor Balog,Dominic A. Urban,Corinne Jud,Barbara Rothen-Rutishauser,Marco Lattuada,Alke Petri-Fink +8 more
TL;DR: The factors that determine NP colloidal stability, the various efforts to stabilize NP in biological media, the methods to characterize NP colloid stability in situ, and a discussion regarding NP interactions with cells are examined.

Modeled Environmental Concentrations of Engineered Nanomaterials (TiO2, ZnO, Ag, CNT, Fullerenes) for Different Regions
TL;DR: The results of this study indicate that risks to aquatic organisms may currently emanate from nano- Ag, nano-TiO(2), and nano-ZnO in sewage treatment effluents for all considered regions and for nano-Ag in surface waters.

TL;DR: The results demonstrate that metal oxide nanoparticles induce a range of biological responses that vary from cytotoxic to cytoprotective and can only be properly understood by using a tiered test strategy such as that developed for oxidative stress and adapted to study other aspects of nanoparticle toxicity.
