Abstract In this cross-sectional study, inductively coupled plasma mass spectrometry (ICP-MS) was used to determine the levels of Cu, Pb, Cd, and As in 55 chicken breast samples collected in Shenyang, China. The estimated daily intake (EDI), target hazard quotient (THQ), total hazard index (HI), and target cancer risk (TCR) were calculated to evaluate potential health risks from broiler breast consumption in different age groups. Heavy metal concentration in broiler breast samples was below the maximum residue limit (MRL) set by national and international regulations. Principal component analysis (PCA) results were similar to those of the hierarchical cluster analysis (HCA), mutually validating the two distinct groups of Pb-Cd-As and Cu, which indicated that there were similar sources for Pb, Cd and As but differ from that of Cu. EDI values for these metals in broiler breasts were far below the corresponding provisional tolerable daily intake values. THQ and HI were well below 1, indicating that there were no non-carcinogenic health risks for residents. The TCR from Pb was negligible in different age groups and the TCR of children exposed to As and Cd were acceptable. However, due to the non-degradability and bioaccumulation of metals, it is recommended that children, especially female children, should be the focus of future long-term surveillance when assessing the carcinogenicity of these metals.

Abstract Investigation of microbial community structures is critical for situ-remediation of heavy metal contaminated soils. For this purpose, we used high-throughput 18S rRNA sequencing method to analyze soil fungal communities in the Shanping village (SPC) and Yanzibian (YZB) tailings situated in northwestern China. The relationships of the fungal community and the environmental factors, including heavy metals and soil chemical properties were analyzed. The results showed that the fungal community richness and diversity in the soils were both trending as control soil > contaminated soil. The compositions and relative abundances of the fungal populations in the two tailings were different, however the dominant fungal phyla of which were almost the same, mainly including Ascomycota, Basidiomycota, Calcarisporillomycota, Mortierellomycota, and Rozellomycota. Further, the Canonical correlation analysis and spearman correlation analyses revealed that Cd, Pb, Cu, Zn, Cr, TP, NO3 −-N, TN, and/or pH were predominantly positive correlation factors for the most abundant fungal phyla Ascomycota and Basidiomycota. Together, we have sorted out certain fungal species, such as s_unclassified_p_Ascomycota, s_unclassified_c_Sordariomycetes, s_Talaromyces_solicola, and s_Cutaneotrichosporon_curvatus, which are probably tolerant to heavy metals in these specific tailing soils. Overall, our results have provided an initial perspective of the fugal community variations of these specific tailing ponds.

Abstract In this work, the kiwifruit branch, a kind of agricultural waste, was reused as a raw material to prepare biochar adsorbent for the removal of Pb(II) from aqueous solution. Then pristine biochar (BC) was further modified to form acid–alkali modified biochar (OBC) and chitosan modified biochar (CBC) to enhance adsorption efficiency toward Pb(II). Characterization experiments with SEM, FTIR and XRD suggested that surface functional groups and crystallization degree of OBC and CBC were all increased in comparison with BC. Batch sorption experiments showed that, compared with BC, the adsorption capacity of Pb(II) by OBC and CBC were improved by 19.57 and 8.37%, respectively. The pseudo-second-order model and the Freundlich model were better for describing the kinetics and isotherms for Pb(II) adsorption onto OBC and CBC, respectively. Accordingly, chemisorption on the heterogeneous adsorption surface played a dominant role in Pb(II) removal.

Abstract It is challenging to estimate the health risks posed by exposure to particulate pollutants due to limited information for chemicals bound to particles in toxicity databases. This study predicted the cancer risks posed by the vapor-phase and fine particulate matter (PM2.5)-bound polycyclic aromatic hydrocarbon (PAH) emissions during diesel combustion in an industrialized city in southern Taiwan by using two different approaches. In the first approach, the cancer risks were estimated based on the vapor-phase and PM2.5-bound PAH concentrations in the exhausts, while the observations of the vapor-phase and PM2.5-bound samples in the in vitro cell toxicity tests, including Ames test, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and tumor necrosis factor-alpha (TNF-alpha) detection were employed to modify the risks posed by the PM2.5-bound emission in the second approach. The results show that the vapor-phase concentrations of total PAH (30,944-118,565 ng/m3) and benzo(a)pyrene toxic equivalence quotient (BaP-TEQ; 8.2–69.1 ng/m3) were significantly higher than the PM2.5-bound concentrations (the total concentration and BaP-TEQ were 11.9–45.0 and 0.27–12.94 ng/m3, respectively), resulting in the dominance of the vapor-phase risk (71–98%) over the total risk (8.92 × 10−9–1.03 × 10−7). With the modification of the cell test results, the total risks were increased to 1.62 × 10−8–1.33 × 10−7. The ratios of the PM2.5-bound risk to the total risk in different conditions have been increased by 2–26 times (from 2–29% to 45–61%), suggesting the mixture effect of PM-bound pollutants on health risk assessment.

Abstract The lockdown, commencing in India from March 23, 2020 to control the escalation of Covid-19 cases, exhibited a positive impact on the air quality. The study attempts to assess the outcome of lockdown on the air quality of Kolkata, India followed by the comparison of six priority pollutants during pre-lockdown, lockdown, and unlock phases. Averaged concentrations of PM10 (72%), PM2.5 (73%), NOx (84%), SO2 (48%), and CO (61%) showed reduction throughout lockdown in comparison with pre-lockdown phase, although no significant reduction was observed in ground-level Ozone. Unlock Phases I and II showed similar concentrations of the pollutants as that in the lockdown period whereas, in unlock Phase-III, the air quality became comparable to that before lockdown. Statistical analysis confirmed that the reduction in air pollution is attributed to atmospheric factors. PCA analysis established significant positive correlation between particulate matters, CO, SO2, and NO x ; however, no significant correlation was observed between NO x and O3. January and December showed the highest load of most of the pollutants. Health risk was evaluated by calculating the Relative risk and Health Air Quality Index, which showed maximum health risk during the pre-lockdown and minimum during lockdown and unlock Phase-II with the highest contributor being PM10. The study outcome manifests a reduction in environmental pollution as a result of controlled anthropogenic activities.

Abstract Objectives Heavy metal exposure has been associated with lung function decline, but there is still a lack of evidence on preschoolers. In this study, we evaluated cross-sectional associations between urinary metal levels and slow vital capacity (SVC) in preschoolers. Methods A total of 1284 children were selected from seven-kindergartens. Urinary concentrations of 23 metals were measured by inductively coupled plasma mass spectrometry. Utilized least absolute shrinkage and selection operator penalized regression was used to select the metals independently associated with SVC. Generalized linear models were used to evaluate the association between urinary metals level and SVC. Result In the single-metal model, we observed negative associations between urinary aluminum, copper, zinc, rubidium, lead and SVC, comparing extreme quartiles the regression coefficients β (95% CI) were −41.01 (95% CI: −78.02, −4.01, P for trend = 0.029), −62.91 (95% CI: −99.85, −25.96, P for trend = 0.004), −33.48 (95% CI: −69.95, 3.00, P for trend = 0.042), −49.45 (95% CI: −86.10, −12.81, P for trend = 0.012) and −55.64 (95% CI: −91.88, −19.40, P for trend = 0.005), respectively. Urinary copper was negatively associated with SVC in boys, urinary zinc and lead were negatively associated with SVC in girls. Similar results were obtained in the multiple-metal model, the β for copper comparing extreme quartiles was −98.90 (-95% CI: −165.50, −32.29, P for trend = 0.006) in boys, the β for zinc and lead comparing extreme quartiles were −54.50 (95% CI: −107.60, −1.41, P for trend = 0.012), −84.32 (95% CI: −151.40, −17.24, P for trend = 0.016) in girls. Conclusions The levels of urinary aluminum, copper, zinc, rubidium, lead were negatively associated with SVC in preschoolers. These associations were different between boys and girls. Further prospective and experimental studies are warranted to clarify the underlying mechanisms.

Abstract Since the modern industrial revolution, the speed of urbanization has accelerated, resulting in a series of ecological environment problems. Fujian province will begin to implement the policy of strengthening the provincial capital in October 2021. Therefore, it is crucial to analyze the ecological maintenance status of Fuzhou and provide a relevant reference for Fuzhou to be built into a national central city. This article takes Fuzhou city as the research area, collects land use data in 2000, 2010, and 2020 from Globeland30, combines remote sensing image data, statistical yearbook data, and Digital Elevation Model (DEM) data, and based on Pressure-State-Responses (PSR) model. A total of 15 indicators were selected to construct the ecological security evaluation system of Fuzhou in 2000, 2010, and 2020, and the weight of each indicator was determined by analytic hierarchy process. Spatial autocorrelation was used to analyze the correlation degree of the land use ecological security index in Fuzhou. The concept of ecological maintenance was introduced to analyze the status of ecological maintenance in Fuzhou during the third period. Finally, the diagnostic model of obstacle factors was used to determine the main obstacle factors affecting ecological security in Fuzhou. The results showed that from 2000 to 2020, the area of cultivated land, grassland and bare land decreased year by year, and transferred 320.63 km2, 25.34 km2 and 9.85 km2 to the artificial surface respectively. The high-value ecological security indexes in 2000, 2010 and 2020 were 27.54%, 28.67% and 30.93% respectively. Therefore, the overall level of ecological security in Fuzhou has improved, but there is a large gap in local ecological security. The area with moderate ecological maintenance degree accounted for 60.15%. From the perspective of the whole city, the very poor ecological maintenance degree mainly concentrated in the downtown area and Pingtan Island, while the very good ecological maintenance degree accounted for very little, mainly distributed in the northwest of Fuzhou. The ecological security index showed the characteristics of high and low-value agglomeration, and the distribution of four clusters in three periods was similar. The main obstacle factors of ecological security in three periods are highway density, population density, surface temperature, intensity of human interference, landscape diversity, GDP per capita, and regional development degree. The ecological security evaluation and ecological maintenance of Fuzhou city is beneficial to provide an efficient decision support tool for the ecological environment protection of Fuzhou City.

Abstract To reasonably ensure good groundwater quality for the safety of users, it is necessary to monitor the evolution of physicochemical parameters of water. This study assessed the evolution of groundwater quality in Xianyang City (Central China) for 6 years and forecasted the water quality index (WQI) using the automatic exponential smoothing model (AESM). The results revealed that pH, Mn, NH4 +, HCO3 − and Ca2+ increased significantly within 6 years. However, there was a slight decrease in K+, NO3 −, SiO2, and Mg2+. Over the course of 6 years, seven out of fourteen wells maintained excellent or good water quality, whereas groundwater quality in the remaining wells fluctuated from excellent to good or from good to poor. The WQI index increased for nine wells, and five of them including well 173, well 457, well 46, well 26, and well C4 manifested an exponential increase of WQI, which was mainly caused by high concentrations of Mn, NH4 +, and NO3 −. The forecast accuracy verified by MASE and sMAPE, which ranged from 0.35 to 1.06 and from 0.04 to 0.69, respectively, demonstrated that the predictions were reliable. The AESM was tested in groundwater quality prediction, indicating that it might be used for actual scientific studies.

Abstract The polycyclic aromatic hydrocarbons’ (PAHs) exposure through day to day cooking activities has been a serious concern for human health due to their carcinogenic nature. Given the Covid-19 conditions, where people are spending extended time indoors, the likely exposure to these compounds will increase for the members involved/not involved in cooking. In this context, this review summarizes different studies undertaken worldwide on PAHs from cooking activities, the sources of exposure (fumes/emissions, dust/depositions), effect of scale (households/restaurants/neighborhoods) of cooking, monitoring process, risk assessment (air sampling and urinary metabolites), global distribution pattern. Proportionately higher number of studies was focused on cooking fumes and emissions while very limited studies aimed at kitchen depositions and dust. Most of the studies have not reported the size of particulate matter considered for determining PAHs exposure from cooking fumes and emissions. The evaluation of reported data becomes more complicated due to difference in sampling and expression units, the number and types of PAHs (parent, oxygenated-PAHs, i.e., o-PAHs, nitro-PAHs, i.e., n-PAHs) studied/found, lack of other intrinsic information (site and control parameters), lack of specific regulations etc. Therefore, such studies require method standardization for future policy development. This review also highlights the gaps and challenges in existing knowledge and future prospects. Graphical Abstract

Abstract Ecological vulnerability is one of the core issues in the study of achieving sustainable development and is important for ecological conservation and environmental management, especially for ecologically vulnerable regions. Scientific assessment of ecological vulnerability can improve decision-making capacity and provide appropriate information for sustainable development. The Hexi Corridor is located in the inland northwest of China, and its ecological environment is very fragile. Under the influence of climate change and human activities, the Hexi Corridor is facing a crisis of ecological degradation. Therefore, this paper assessed the influence of various factors on ecological vulnerability, followed the principles of scientificity and data accessibility, and constructed a comprehensive assessment framework to reflect the spatio-temporal characteristics of ecological vulnerability in the Hexi Corridor from three aspects: natural factors, socio-economic factors and human interference factors so as to provide theoretical and practical guidance for regional ecological protection. The results showed that: (1) The ecological vulnerability of the Hexi Corridor was dominated by extreme vulnerability, mainly in the arid desert region, while mildly and lowly vulnerable areas were mainly distributed in the southern Qilian Mountains and the plain oasis region, which was closely related to its physical geography. The index values showed an overall decreasing trend, and the environmental situation was improving from 2000 to 2020. (2) The distribution of ecological vulnerability had obvious directional characteristics, and it gradually decreased from north to south. Moreover, it exhibited a significant positive spatial correlation, and its spatial aggregation pattern was basically consistent with the spatial distribution state. (3) Based on the spatio-temporal patterns of ecological vulnerability, the Hexi Corridor was divided into five zones: ecological core protection zone, integrated ecological monitoring zone, ecological optimization concern zone, ecological restoration management zone and ecological potential governance zone. Different environmental protection policies have been taken for different zones according to its basic conditions. Graphical Abstract Highlights Spatial principal component analysis (SPCA) method was used to analyze the ecological vulnerability factors based on the GIS technology. The partitions of ecological vulnerability for configuration and optimization has been classified and practical application. Geographic detector and national policies were considered for ecological vulnerability driver factors.
