“…Regulations and legalization for controlling TiO 2 NPs and other engineered NPs (ENPs) are unsure, living the interpretation of the scientific data challenging to the government, agencies, industry, and consumers. Recently, suggestions for the safe handling of TiO 2 NPs and other engineered NPs (ENPs) were proposed by Besha et al [ 153 ], highlighting the mitigation approaches to curtail the possible hazard effects of ENPs.…”

Nanotechnology has enabled tremendous breakthroughs in the development of materials and, nowadays, is well established in various economic fields. Among the various nanomaterials, TiO2 nanoparticles (NPs) occupy a special position, as they are distinguished by their high availability, high photocatalytic activity, and favorable price, which make them useful in the production of paints, plastics, paper, cosmetics, food, furniture, etc. In textiles, TiO2 NPs are widely used in chemical finishing processes to impart various protective functional properties to the fibers for the production of high-tech textile products with high added value. Such applications contribute to the overall consumption of TiO2 NPs, which gives rise to reasonable considerations about the impact of TiO2 NPs on human health and the environment, and debates regarding whether the extent of the benefits gained from the use of TiO2 NPs justifies the potential risks. In this study, different TiO2 NP exposure modes are discussed, and their toxicity mechanisms—evaluated in various in vitro and in vivo studies—are briefly described, considering the molecular interactions with human health and the environment. In addition, in the conclusion of this study, the toxicity and biocompatibility of TiO2 NPs are discussed, along with relevant risk management strategies.

“…On the basis of the conducted review of research results published so far, it can be assumed that a significant number of companies adjust their operations to the applicable legal requirements; that is why various systemic solutions (e.g. Neves et al , 2017) or investment activities (Rode et al , 2010; Damian et al , 2019; Besha et al , 2020) are undertaken. Furthermore, pro-environmental behaviours are fostered by personal relationships with nature (Whitburn et al , 2020), health awareness (Shimoda et al , 2020) and a sense of guilt (Muralidharan and Sheehan, 2018).…”

PurposeThe aim of this paper is to identify factors moderating the process of managing environmental objectives and to develop potential behavioural scenarios related to this process.Design/methodology/approachThe main research method used by the authors was a systematic literature review. The applied procedure was consistent with the general methodology of conducting research and the methodology of research in management sciences. The conducted literature review was supplemented with an analysis of grey literature.FindingsA number of factors influence the process of managing environmental objectives. Legal factors can stimulate the introduction of pro-environmental measures. The lack of universal legal regulations encourages unethical actions. The ethical values deserve special attention. If their level is high, then even the factors embedded in the environment that foster unethical behaviours are of little importance. In this sense, the performed literature review confirms the theory proposed by Locke. Managerial factors, including remuneration for the achievement of environmental objectives, may be the reason for weakening the process of minimising the negative impact on the environment.Originality/valueOn the basis of the conducted research and various theories of objectives, the authors formulated practical managerial recommendations aimed at reducing the number of errors in the process of setting environmental objectives.

“…With the rapid development of nanotechnology in recent years, nanoparticles (NPs) have exhibited various special properties due to their extremely small size, such as the surface effect, quantum size effect, small size effect, and macroscopic quantum tunneling effect. NPs have been widely used in the fields of optics, electronic biomedicine, food, cosmetics, environmental energy, and chemistry [1][2][3]. Additionally, the biological effects of NPs have also attracted the interest of researchers.…”

Development of a Strategy for Enhancing the Biomass Growth and Lipid Accumulation of Chlorella sp. UJ-3 Using Magnetic Fe3O4 Nanoparticles

In this study, magnetic Fe3O4 nanoparticles (NPs) were used as an effective enhancer to increase the biomass and total lipid production of Chlorella sp. UJ-3. It was found that the biomass of algal cells increased significantly when they were exposed to low concentrations of Fe3O4 NPs (20 mg/L), while the best total lipid content of algal cells was achieved when they were exposed to high concentrations of Fe3O4 NPs (100 mg/L). Therefore, we established a strategy to promote the growth and lipid accumulation of microalgae by initially exposing the algal cells to low concentrations of Fe3O4 NPs and then treating them with an increased concentration of Fe3O4 NPs after 12 days of culture. For this strategy, the biomass and total lipid production of algal cells increased by 50% and 108.7%, respectively, compared to the untreated control. The increase in lipid production and change in the fatty acid composition of Chlorella cells were found to help them to cope with the increased number of reactive oxygen species produced due to oxidative stress in alga cells after the addition of Fe3O4 NPs. This study provided a highly efficient way to improve the lipid production of microalgae using nanoparticles.
