Abstract Groundwater contamination by heavy metals is a worldwide serious issue due to its severe risks to human health. In the present study, a total of 49 groundwater samples were collected and analyzed for eleven trace elements (Al, Cr, Cd, As, Zn, Se, Sn, Ni, Pb, Mn, and Cu) in the west of Minia area, Egypt, to determine groundwater contamination by heavy metals and their impact on groundwater use for drinking and human health as a result. Multivariate statistics, geospatial mapping, and health risk assessment approaches are used to evaluate the potential non-carcinogenic and carcinogenic hazards in the research area and determine both natural and anthropogenic consequences of identified trace elements on local groundwater quality. The heavy metal concentrations (in µg/l) in the groundwater samples were found to be in the following order: Zn (154.5) > Al (40) > As (37.4) > Sn (32) > Cr (28.4) > Hg (25.6) > Cu (21.8) > Cd (16) > Ni (15.4) > Pb (6.5). Heavy metals measurements revealed that As, Hg, and Cu do not meet WHO Guidelines Values, indicating a risk to human health from the consumption of groundwater. Zn > Al > As > Sn > Cr > Hg > Cu > Se > Cd > Ni > Pb was shown to be the order of the mean values of chronic daily heavy metal consumption for new-borns, children, and adults. Continuous oral intake of groundwater loaded with heavy metals could result in carcinogenic and non-carcinogenic concerns, posing serious health dangers to people throughout the life course.
地下水重金属污染严重危害人类健康，是一个世界性的严重问题。本研究在埃及Minia地区西部采集了49份地下水样品，分析了11种微量元素(Al、Cr、Cd、As、Zn、Se、Sn、Ni、Pb、Mn和Cu)，以确定地下水重金属污染及其对地下水饮用和人体健康的影响。采用多元统计、地理空间制图和健康风险评估方法评估研究区域潜在的非致癌性和致癌性危害，并确定已确定的微量元素对当地地下水质量的自然和人为后果。地下水样品中重金属浓度(µg/l)的大小顺序为:Zn (154.5) > Al (40) > As (37.4) > Sn (32) > Cr (28.4) > Hg (25.6) > Cu (21.8) > Cd (16) > Ni (15.4) > Pb(6.5)。重金属测量显示，砷、汞和铜不符合世卫组织准则值，表明地下水的消耗对人类健康构成风险。新生儿、儿童和成人慢性每日重金属摄取量平均值的顺序为Zn > Al > As > Sn > Cr > Hg > Cu > Se > Cd > Ni > Pb。持续口服含有重金属的地下水可能导致致癌和非致癌问题，对人的一生构成严重的健康危害。

Abstract In order to investigate drinking water sources of inhabitants residing in the South coastal area of Cambodia, fifty-nine and twenty-three water samples were collected from Kampot and Kep provinces, respectively. On-site and chemical measurements were performed following USEPA methods. Analytical results revealed that 28.6% of tube well, 28.6% of dug well and 40% of pond were saline. Approximately, 2.6% of tube well and 17.9% of dug well had As > 10 ppb. Likewise, 29.3% of tube well, 28.6% and 60% of pond had Fe > 0.3 mg L−1 whereas 47.5% of tube well, 45.7% of dug well and 20% of pond had Mn > 0.1 mg L−1. Moreover, 2.5% tube well had F- > 1.5 mg L−1; 5.7% of tube well and 14.3% of dug well had NO3 - > 50 mg L−1. This study suggests that some inhabitants residing in the Southern coastal area of Cambodia are exposed to contaminants of health concern (As, F-, NO3 -) and experienced water salinization and esthetic properties through their water consumption. As such, water treatment technologies for removing As, F- and NO3 - are necessary for coastal inhabitants to minimize their potential health risks.

Abstract The ecological aspects such as environmental factors, socioeconomic constraints and demographic parameters are one of the key aspects to examine the health benefits of human subject and used as ready reference in eco system modeling. Presently, there are various kinds of deadly diseases and disorders who are liable for affecting the human health and impacting the eco framework of whole world. The virus such as Corona, Swine Flu, omicron and others are one of the best examples for the research community to understand the vulnerability of human health in relation to these unpredictable causes. As per report of world health organization every year, more than 10 million people are affected by such ecological and environmental disbalance. The burden of ecological aspects apparently affecting the working of various organs in human subject. There is a need to understand this ecological model in relation to health of human subjects. In this study, a cohort-based data set of ecological pollutants and physiological signals such as ECG and anthropogenic data of human subjects were extracted from Maharashtra from 2015 to 2021. As per neural network-based hazard ratio was calculated and observed to be deplorable among unhealthy and health categories of human subjects. It has been concluded that the accumulative eco system is responsible for overburden to organs of living beings and policy makers must focus on the facts of study for modern management framework designs.

Abstract Polychlorinated biphenyls (PCBs) are banned toxic contaminants according to the Stockholm Convention of persistent pollutants (2001); however, they continue to be prevalent in the environment of Pakistan. The current study evaluates the risk to infants exposed to PCBs in breast milk from urban centers of Pakistan. The ∑14PCB concentrations ranged from ND to 118.36 ng/g lipid weight (l.w.) with a mean of 11.76. ± 4.88 ng/g l.w. These levels are greater than concentrations previously reported from Asia. The quantified PCB profile was also significantly (p < .05) related to the age of the mother while a negative correlation was observed with diet pattern (−0.26), fat content (−0.63), number of children (−0.185), and lactation (−0.19). There were significant differences among test locations with greater bioaccumulation observed in breast milk collected from urbanized Rawalpindi compared to less urbanized Jhang. The calculated estimated daily intakes of dioxin-like PCBs for infants were considerably higher than the recommended daily intake suggested by different organizations. The calculated hazard ratio (HR > 1) indicates health risks to infants in selected study regions.

Abstract The present study was taken with a primary objective to estimate the groundwater quality and its suitability toward sustainable crop productivity in an agriculturally dominant semi-urban area. Elevated levels of nitrate have severe health impacts and affect the human health. Hence, health risks associated with the consumption of nitrate contaminated water were estimated for adults and children in Sonipat district, Haryana. In general, the groundwater was found to be slightly alkaline and moderately hard. The anionic abundance was verified as F– < NO3 – < HCO3 – < SO4 2– < Cl–, whereas, the cationic abundance was verified as Ca2+ < Mg2+ < K+ < Na+. Concentration of nitrate varied from 1.34 mg/L to 565 mg/L, with an average value of 47.6 mg/L, and 46% of the groundwater samples had nitrate concentration of more than 45 mg/L. As per the results of Wilcox plot, only 34% of samples were suitable for crop productivity, whereas 23% of the samples fell in category-II of the permeability index. The non-carcinogenic health risk assessment further suggested that hazard quotient values for nitrate reached as high as 18.35 (children), and 13.57 (adult male), suggesting that health risk degree of children has greater health risk than adults in the study region. Overall results suggest an urgent need for intervention to adopt suitable health risk measures to reduce exposure toward nitrate contaminated drinking water. Moreover, agricultural practices must be improved to increase the crop productivity in the affected areas.

Abstract Indoor environmental quality is an important parameter in determining the occupant’s health status in the office environment. To show the important connection between human health and environmental quality, this study was carried out to investigate the relationship between Indoor Air Quality (IAQ), the prevalence of health symptoms, selected personal factors, and office characteristics among university office workers. Six parameters of IAQ, including air temperature, relative air humidity, formaldehyde, particulate matter, carbon monoxide, and carbon dioxide, were measured by a direct reading instrument. We found eye irritation, dryness, and itching were the most common health symptoms, and the prevalence of weekly dermal, mucosal, psychological, and general symptoms were 60.9%, 75.4%, 60.8%, and 64.7%, respectively. Age, and working experience were associated with general symptoms, while gender was related to dermal symptoms. Furthermore, we observed that the prevalence of health symptoms in 15–30 years old office rooms was significantly higher than others, and health symptoms among employees with 11–20 years of working experience were higher than other age groups. Strategies like using a proper ventilation system, air cleaners, maintaining social distance, humidity, and temperature control can help to improve indoor air quality and protect us from the risk of airborne transmitted diseases.

Abstract An overview of recent European background inorganic arsenic (iAs) levels and related human health risks is given. The main aim was to summarize and confront the existing concentration data, unresolved low dose-response issues (linearity, nonlinearity, threshold, adaptation, hormesis), and methodological approaches hampered by several uncertainties on several levels. Daily doses are calculated from dietary intake (food, water As content multiplied by intake frequencies) and compared by reverse calculated doses from urine iAs metabolites (iAs + dimethylarsenic acid + monomethylarsonic acid) from human biomonitoring data (both in a range 0.05–0.60 μg kg−1 bw/day for children, adolescents and adults). With data obtained a health risk assessment is performed by existing regulation norms. Several flaws are addressed. For instance, urine DMA used as iAs metabolite is overestimated as its source can also be food items. Further, existing regulation norms (which are under reevaluation by US EPA) are based on a linear dose-response approach valid for high exposure only and highly questionable at low exposure levels. Nevertheless, even by using the conventional approaches with discussed flaws leading to anticipated overestimation, the potential cancer risk was estimated to be of low concern regarding the margins of exposure (MOE) for investigated age groups with average food intake and average iAs concentration in diet (15.3–40.6), supported by MOE calculated from human biomonitoring data (21.4).
摘要概述了最近欧洲背景无机砷(iAs)水平和相关的人类健康风险。主要目的是总结和面对现有的浓度数据，未解决的低剂量反应问题(线性，非线性，阈值，适应，激效)，以及在几个层面上受到几个不确定因素阻碍的方法方法。每日剂量根据膳食摄入量(食物、水中砷含量乘以摄入频率)计算，并与人体生物监测数据中尿液砷代谢物(砷+二甲基larsenic酸+单甲基larsonic酸)的反向计算剂量进行比较(儿童、青少年和成人的剂量范围均为0.05-0.60 μg kg - 1 bw/天)。根据获得的数据，根据现有法规规范进行健康风险评估。解决了几个缺陷。例如，作为iAs代谢物的尿液DMA被高估了，因为它的来源也可能是食物。此外，现有的监管规范(正在由美国环境保护局重新评估)基于线性剂量反应方法，仅对高暴露有效，对低暴露水平非常可疑。然而，即使使用常规方法(存在讨论过的缺陷，导致预期的高估)，根据人类生物监测数据计算的MOE(21.4)，对于平均食物摄入量和饮食中平均iAs浓度(15.3-40.6)的被调查年龄组，潜在的癌症风险估计与暴露边际(MOE)有关。

Abstract PM10 levels, concentrations of trace metals, source apportionment, and potential health risks exposed to PM10-bound metals via inhalation pathway were investigated at industrial, traffic and residential sites in Bac Giang, Vietnam. The average PM10 concentration exhibited the highest value at the industrial sites, followed by the traffic sites, and the residential sites. The PM10 mass was 1.38 to 3.39 times higher than the National Air Quality Standard (QCVN 05:2013/BTNMT) (150 µg/m3 for 24 h). The concentrations of non-crustal trace elements (As, Cd, Cr, Ni, Pb, V, and Zn) at industrial sites were at a higher level than at the traffic and residential sites. Enrichment Factors analysis and principal component analysis (PCA) were performed for source apportionment of PM10 in Bac Giang. Four potential emission sources including traffic-related emissions, industry, use of pesticides, and coal combustion were identified. The results of pollution load index and health risk assessments showed higher contamination levels and higher non-carcinogenic and carcinogenic risks posed to children and adults in the vicinity of the industrial sites than the traffic and residential sites. The HQ value for Cr greater than 1 at industrial sites expressed the adverse health effects among humans should be a concern.

摘要研究了越南北江地区工业、交通和住宅场所PM10水平、微量金属浓度、来源分配以及吸入途径暴露于PM10结合金属的潜在健康风险。PM10平均浓度以工业场所最高，交通场所次之，居住场所次之。PM10质量比国家空气质量标准(QCVN 05:13 13/BTNMT) (24 h 150µg/m3)高1.38 ~ 3.39倍。非地壳微量元素(As、Cd、Cr、Ni、Pb、V、Zn)在工业场所的浓度高于交通和居住场所。利用富集因子分析和主成分分析(PCA)对北江地区PM10污染源进行了解析。确定了四种潜在的排放源，包括交通相关排放、工业、农药使用和煤炭燃烧。污染负荷指数和健康风险评估结果表明，工业场地附近的污染水平和对儿童和成人构成的非致癌性和致癌性风险高于交通和居住场地。工业场所铬的HQ值大于1表明，对人类健康的不利影响应引起关注。此外，在所有采样点，通过吸入接触接触有毒元素的成年人的健康风险比儿童更明显。

Abstract To identify the status of the water resources carrying capacity in Taizhou City in China, this article selected 17 evaluation indicators and used principal component analysis to analyze the factors influencing that capacity. Then, an evaluation model was established to assess the water resources carrying capacity in Taizhou City from 2011 to 2020, and a multiple linear regression model was established to predict the total water consumption from 2021 to 2026. The results showed that as Taizhou has constructed a water-saving society, its water resources carrying capacity has gradually increased. As a result, the total water consumption is predicted to show a downward trend from 2021 to 2026. Based on the evaluation and prediction results of water resources carrying capacity, some water resources management and control measures for Taizhou were proposed, such as strengthening strict water resources management, upgrading to the water consumption structure and securing the ecological flow of downstream rivers. This research can provide scientific support for the rational development and utilization of water resources in the Taizhou City and can also set an example to similar studies over the world.

Abstract Chinese Farming-pastoral Ecotones (CFPE) is the largest ecologically fragile zone in China. The dynamic prediction and impact factors analysis of landscape ecological risk based on LUCC have an important significance for effectively resolving ecological and environmental risk . In this paper, CA-Markov and BRT models were used to quantitatively analyze dynamic change, evolution characteristics, and influencing factors of landscape ecological risk.The results showed that: (1) LUCC types significantly changed from 2000 to 2040, especially in the bareland regions, which decreased by 1.64 times from 2000 to 2020, mainly transferred out to grassland and farmland. (2) The overall ecological risk showed a trend of increasing first and then decreasing. The highest ecological risk regions reached an area of 192,000 km2 in 2020 and decreased by 1.78 times from 2020 to 2040, these areas showed high spatial correlation and aggregation. (3) Topographical, climate, and socioeconomic factors had certain impacts on landscape ecological risk. Elevation (24.4%) was the most important factor affecting ecological risk, followed by temperature (19.1%), precipitation (15.7%), slope (13.6%) and GDP (8.4%). The study not only proposes a novel method regarding prediction and quantitative assessment of ecological risk based on influencing factors, but also provides a more precise and specific decision-making basis for sustainable development of ecological safety and social economic in the CFPE.
