“…Our group identified the PbO 2 and PbO particles in the sediment of tap water by SEM/EDS and XPS (Figure S6, see the Supporting Information). Meanwhile, the micro- and nanosize particles of lead compounds were also in fine particulates (<1 μm) or in dust and soil. ,, The fine particulates (<1 μm) bound with lead compounds had the transport capacity into the maize plant . Although hydroponic experiments do not simulate the field condition and might overestimate the toxicity of nanoparticles, the hydroponic system is still the most used method to evaluate the toxicity of NPs due to their easy to control plant growth condition .…”

“…The mass application of lead products has greatly increased the possibilities for environmental release and their potential risks. Researchers have found that lead oxide nanoparticles (LONPs) usually exist in aerosol particles (particulate matter), urban soil/dust, agricultural fields, ,, and domestic drinking water . Lead can cause serious injury to the human brain, nervous system, red blood cells, and kidneys, especially for children under 6 years of age.…”

PbO x (PbO 2 and PbO, x = 1, 2) nanoparticles are emerging contaminants in dust, soil, and water due to extensive application of commercial lead products. As far as we know, the current studies are first conducted to understand the phytotoxic effects of PbO 2 (10 ± 3 nm) and PbO NPs (20 ± 5 nm) on maize (Zea mays L.) grown in hydroponic treatments. The exposure assays indicated that phytotoxic effects were dose-and size-dependent on PbO x NPs. Water uptake would be the crucial mechanism to govern the effects of PbO x on maize seed germination and root elongation, while the nanosize of particles and water transpiration processes would control maize growth and biomass production. PbO x NPs significantly influenced the macro-and micronutrients in roots and shoots of maize and significantly affected the maize growth and grain development. Our findings provide clear-cut evidence that PbO/PbO 2 NPs can bioaccumulate in maize cell organelles via apoplastic and symplastic routes from the seed and root pathways along with water uptake and transportation. The significance of this research elucidates the impacts of PbO/PbO 2 NPs on food security and indicates the threat of emerging PbO/PbO 2 NPs to human dietary health.

“…In addition, in recent years, the notion of risk‐based security design has been increasingly promoted as an alternative to the more traditional prescriptive approach, which makes it even more important to establish appropriate risk acceptance criteria (Papanikolaou, 2009; Vanem, 2012; Van Coile, Hopkin, et al., 2019; Van Coile, Jomaas, et al., 2019). At the same time, research on the impact of risk aversion on risk acceptability and related decision‐making and the mechanism of this impact (Cannella et al., 2019; De Silva et al., 2017), as well as the application of acceptable risk theory in environmental health risk assessment, has attracted considerable attention in recent years (Ai et al., 2019; Gonzales‐Gustavson et al., 2019; Madruga et al., 2019).…”

Exploring acceptable risk in engineering and operations research and management science by bibliometric analysis

View full text Add to dashboard Cite

As the decision-making basis for "safety" in risk management and risk assessment activities, acceptable risk has always been an important topic of risk-related research. Based on the records in the Science Citation Index Expanded database and Social Sciences Citation Index database via the Web of Science Core Collection, 1124 articles or reviews related to acceptable risk in engineering and operations research and management science were retrieved. These documents, published between 1961 and 2021, covered 3056 authors, 75 countries/territories, 1296 institutions, and 323 journals. In this study, bibliometric data such as annual growth trends were analyzed by using descriptive statistics. Through the co-occurrence maps created by CiteSpace and Gephi, the most productive and influential countries/territories, institutions, and authors as well as their cooperation networks were identified. Further analysis was conducted to determine the core publications and publication sources in this field through cocitation analysis. Insights into focus areas and research topics over time were obtained through keyword co-occurrence analysis. This study provides a macroscopic overview of acceptable risk research and may help researchers better understand this research field and predict its dynamic directions.

The direct ingestion of indoor dust particles at historical heritage sites is a primary exposure pathway for employees to heavy metals. Water-soluble ions (WSIs) and heavy metal levels, sources, bioaccessibility, and health risks associated with indoor dust in the Mogao Grottoes were analyzed using comprehensive methods to determine the differences in the concentrations and distribution characteristics of WSIs and heavy metals between statue dust and floor dust. The concentrations of WSIs and heavy metals and the magnetic values of χ lf and SIRM in indoor dust were higher than those in street dust and topsoil. The mean χ lf and SIRM of statue dust particles were 100.3 × 10 − 8 m 3 k g − 1 and 1686.9 × 1 0 − 5 Am 2 k g − 1 . Specifically, the concentration of Pb was 277 mg k g − 1 , 15-fold higher than the background value, indicating the continual receipt of heavy metals with high magnetic minerals during dust deposition. WSIs mainly originate from the weathering of surrounding rocks and earthen plaster; Pb originates from the shedding of paint of murals and sculptures; and Zn, Cu, and magnetic minerals originate from traffic sources. The bioaccessibility of heavy metals is high in the gastrointestinal phases of indoor dust. Overall, the health risks posed by heavy metals in indoor dust were low, with moderate to high risks in individual caves. Ingestion presents the highest noncarcinogenic and carcinogenic risk to employees. These results provide essential knowledge on indoor dust characteristics in the Mogao Grottoes, facilitating strategies for dust pollution mitigation and employee health risk control.
