Authors: Bollino Ruggero , Yu Helen , Luppi Davide , Zizzo Maurizio
Published: May 2024

Enhanced Recovery After Surgery (ERAS) protocols reduce the length of hospital stay (LHS), complications, and costs for many elective surgical procedures. The ERAS protocol concerns a multimodal, multidisciplinary, standardized, evidence-based approach to minimize stress for patients undergoing surgery. A similar, structured approach appears to improve outcomes, including mortality, for patients undergoing high-risk emergency general surgery, and emergency laparotomy, in particular. Recently, several studies have been published, including new guidelines, analyzing the benefits of ERAS protocols in emergency surgery and trauma patients. The aim of this chapter is to analyze the available data and the benefits of using ERAS protocols in patients undergoing emergency and trauma surgery.
Biomaterials-Based Hydrogels for Therapeutic Applications
Authors: Chelu Mariana , Magdalena Musuc Adina
Published: May 2024

Conventional therapeutic models based on the premise of a universal solution are facing a decrease in efficiency, emphasized by the large number of patients who show resistance or who do not respond positively to classic treatments. This perspective highlights the urgency for more precise approaches based on personalized treatments that are adaptable to the specific complexities and unique challenges faced by each patient. Hydrogels are biocompatible and biodegradable systems for well-controlled and targeted administration of therapeutic agents, being formed by 3D reticulated networks of water-soluble polymeric biomaterials, of natural, synthetic, or hybrid origin, with specific intrinsic and extrinsic properties. Due to the easily adjustable porous structure, hydrogels allow the encapsulation of macromolecular drugs, proteins, small molecules, cells, hormones, or growth factors in the gel matrix and their subsequent controlled release. The biomaterials used, the crosslinking methods, the design, and the functionalization strategies in obtaining hydrogels with improved properties are presented. The different possibilities of application are described transdermally, as dressing materials, oral, ocular, spray-able, or injectable, up to the intracellular level. This chapter extensively investigates the advances and unique advantages of hydrogels that enable effective, noninvasive, personalized treatments and provide greater patient comfort for a wide range of applications.

Authors: Çakmak Demir Selin , Yazıcı Dilek
Published: May 2024

Immunotherapy has recently emerged as an important tool in the treatment of various malignancies. However, increased use of immune checkpoint inhibitors (ICIs) has brought attention to the associated adverse events, with hypothyroidism being a noteworthy complication. This review explores the mechanisms underlying immunotherapy-induced hypothyroidism and its management. The importance of distinguishing between primary and secondary hypothyroidism in the context of immunotherapy is emphasized, as timely intervention is critical in preventing adrenal crises. Not all patients with immune-related hypothyroidism are treated with levothyroxine. Additionally, only in severe toxicities, ICIs are hold. So, determining the management strategy is important for endocrinologists and oncologists. Therefore, multidisciplinary approach is crucial for immune-related adverse reactions (irAEs). In conclusion, this review provides a comprehensive overview of immunotherapy-induced hypothyroidism, encompassing its mechanisms, diagnostic considerations, and management strategies. By enhancing our understanding of this adverse event, endocrinologists can manage potential complications associated with immunotherapy.
From Fluids to Forecasts: The Promise of Small Extracellular Vesicle miRNAs in Revolutionising Cancer Diagnostics
Authors: Kartik Kumar Sarwareddy , Venkata Sasidhar Manda
Published: May 2024

Small extracellular vesicle (sEV) RNAs, particularly microRNAs (miRNAs), have emerged as pivotal biomarkers for cancer diagnosis and prognosis. Encapsulated within sEVs, these miRNAs reflect specific cellular characteristics and disease states, offering a window into cancers’ molecular underpinnings. Notably, miRNAs, such as miR-7977, miR-98-3p, miR-620, and miR-17-5p in lung cancer and miR-373, miR-1246, miR-223-3p, and miR-21 in breast cancer, have been identified in sEVs extracted from various bodily fluids, including blood, urine, and saliva. Their remarkable stability and ease of isolation make them prime targets for non-invasive cancer detection strategies. The fold change of these miRNAs is intricately linked with cancer progression, metastasis, and therapeutic responses, underscoring their potential as diagnostic and prognostic markers. Traditional detection methods like quantitative reverse transcription-polymerase chain reaction (qRT-PCR) have been foundational; however, recent biosensing technologies, such as nanopore sequencing and microfluidic chips, offer enhanced sensitivity and specificity for detecting miRNAs in clinical samples. These innovative approaches refine the detection process and pave the way for real-time monitoring of disease progression and treatment efficacy. Overall, the collective evidence positions sEV miRNAs as robust indicators for cancer, signalling a shift towards personalised cancer care that emphasises early detection and tailored treatment strategies.

Authors: Bantie Zenamarkos , Tezera Asmare , Abera Desalegn , Nega Tesfa
Published: May 2024

In construction engineering, there is currently a strong emphasis on finding construction materials, mainly the binder which plays a crucial role, that meet multiple criteria, including sustainability, cost-effectiveness, durability, and reduced environmental impact. However, there is a growing interest in exploring alternatives to traditional binders to address the limitations associated with their production and use. One such alternative is the use of naturally occurring materials like clay. Clay deposits are abundant and widely available, making them a sustainable resource for construction applications. Moreover, clay contains significant amounts of silica and alumina, which are key components for inducing pozzolanic reactions that contribute to the strength and durability of concrete. In recent studies, nanoclays (NCs) have emerged as a promising addition to construction materials as supplementary cementitious materials. These nanoparticles possess unique properties that can enhance the performance of concrete. Nanoclays significantly improve the compressive strength, sustainability, and durability of concrete structures. The high surface area and reactivity of nanoclays facilitate better bonding between cement particles, resulting in enhanced mechanical properties. This chapter aims to discuss the state of the art on performance enhancements of building materials that employ different types of nanoclays in place of conventional binders and the future trends.

Authors: Arosa Yago , Damián Rodríguez-Fernández Carlos , López Lago Elena , De la Fuente Raúl
Published: May 2024

In the last decade, the intrinsic tunability of ionic liquids has attracted interest well beyond the disciplines that inaugurated the research on these materials at the beginning of the 1990s. One of these emerging fields is photonics, where the possibility of designing materials with task-specific optical responses is promising for a large number of potential applications. Among the optical properties of ionic liquids, refractive index has been the subject of a thorough investigation because of its relevance in the performance of most optical devices. In this chapter, we address the recent experimental and computational advances on the characterization of the refractive index of ionic liquids and the relations of this magnitude with their structure. Furthermore, we provide an important review of works introducing ionic liquids as essential optical materials in diverse applications.

The use of bio-pesticides is an effective way to manage different biotic stresses in vegetable production. By adopting this approach, we can confidently ensure safer and healthier vegetable production. This chapter provides a brief explanation of the different types of biopesticides, their mode of action, and their application in vegetable production toward the production of zero residues vegetables.
Perspective Chapter: Patient Advocacy - From a Seat at the Table to Equal Stakeholders
Authors: L. Wale Janet , Hamerlijnck Dominique
Published: May 2024

Much has changed in individual and policy level patient advocacy in the years since the late 1980s when HIV/AIDS activists challenged the United States medical product regulator and aspects of how randomised controlled trials are conducted. Delays in access to innovative, life-saving medical interventions continue to be a key topic. We provide storylines to explore three interrelated pathways. The first follows the involvement of patients in the medical product lifecycle and clinical trial regulation, where the biopharmaceutical industry is a major stakeholder. The second follows the course of evidence-based practice and patients, the need for outcome measures of patient experience data and patient-relevant outcome measures that incorporate the patient voice into person-centred models of healthcare; and how regulators and HTA bodies are accelerating access to innovative medical products. The third storyline uses the European Union with its public-private funding of medical and healthcare research as a case study to highlight how patient advocacy is changing. Following the maturation of patient advocacy from patients as research subjects to patient involvement and centredness throughout the medical product lifecycle, we suggest possible next steps to continue to evolve patient advocacy into equal stakeholders within healthcare and innovative medical product development.

Authors: Olufemi Adeniyi Samuel , Abiodun Olufemi-Adeniyi Olubukola
Published: May 2024

Learners with special educational needs are faced with multiplicities of challenges in and outside school environments. These challenges range from social, psychological, emotional to academics. The problems are often compounded when learners with special needs find themselves in rural communities where knowledge, understanding and pedagogical skills are lacking by teachers. It then beholds on teachers to advance his or her teaching by creatively managing the curriculum to meet the diverse needs of students with special educational needs under his or her instructional watch. This work anchors on Rogers’ diffusion theory in education. This theory was used as a conceptual model to understand how teachers implement the innovations they had learned. The basic element of Rogers’s diffusion theory in education hinged on innovation decision process namely: knowledge, persuasion, decision, implementation and confirmation. In view of these, teachers as critical stakeholders should prepare to manage curriculum to meet needs of learners with special needs in Nigeria rural communities through creative adaptation of curriculum in view of diverse learners, flexible pedagogical application, in-depth knowledge of instructional contents, resilience, encouraging and managing innovation as well collaboration and accommodation to promote all-inclusiveness in instructional delivery and knowledge acquisition by the students.

Authors: Zitha Innocent , Mokgaetji Mokganya Georgina , Sinthumule Orifha
Published: May 2024

There are clear signs that the COVID-19 pandemic has had a straining impact on the higher education sector in South Africa and the far reaches of the world. This chapter examines (Science, Technology, Engineering, Mathematics) STEM lecturers’ experiences with digital assessments and perspectives on the continuity of digital transformation in the higher education sector in the post-COVID-19 era at one of South Africa’s rural universities. In 2022, a survey of ten (10) lecturers was conducted and the reports were also consulted by four (4) e-learning practitioners to obtain their views on the use of online learning and contact courses in the post-pandemic period. A qualitative research approach was used to understand the puzzling issues faced by STEM lecturers at a previously disadvantaged institution in Limpopo Province. The results of this study show that there is a puzzling conundrum that hinders the integration of effective online learning. Furthermore, online education as the new normal in the post-COVID-19 era seems unattainable due to extremely complex and difficult-to-understand mathematical symbols. Software and tools proved to be limitations in terms of establishing an interactive learning environment for students and lecturers on online learning platforms. Lecturers’ use of learning and teaching platforms deteriorated due to numerous unknown challenges, but also the tightening of COVID-19 restrictions. Furthermore, the results showed that science and mathematics lecturers believe that contact learning remains irreplaceable across generations and eras as some are not technology enthusiasts. This paper recommends that the lack of technological systems as well as technological resistance and reluctance to adopt transformative pedagogy and innovative practices should not be viewed as a thorny issue to end the dominance of online education in STEM courses.
Quality as a Sustainable Tool against Institutionalized Corruption
Authors: Dávila Pablo , Mantilla Diego
Published: May 2024

Quality management systems are crucial for controlling and administering public institutions, promoting a culture of continuous improvement and reducing costs. This research evaluated three critical aspects in the fight against corruption in public procurement: risk management, compliance, and the implementation of ISO 37001 standards. Factors such as collusion between officials and companies, repetitive contracts, solvency checks, supplier experience, and certification were considered. The study found that collusion, procurement requirements, and supplier experience formed a pattern of fraud and corruption in companies. Compliance planning, internal procurement guidelines, training, commission monitoring, and contract evaluation were effective, but areas like planning and contract evaluation needed improvement. Low scores in implementing ISO 37001 standards indicated recognition but incomplete adoption, highlighting the need for stronger anti-corruption policies, ethical codes, and corruption identification practices.
Force Measuring System with Zero-Compliance Suspension
Authors: Mizuno Takeshi , Takasaki Masaya , Ishino Yuji
Published: May 2024

The principle and classification of force measuring system with zero-compliance suspension are described. A zero-compliance suspension consists of series-connected suspensions, one of which operates to cancel the variation of length of the other suspension. As a result, the total length of the connected suspensions is invariant even when force acts between the ends. In the force measuring system, one end is fixed to the base and force to be measured is applied to the other end (point of application). The force is estimated from the displacement of the connection point of the suspensions that is to be detected (detection point). This principle of measuring force is explained in a basic model. Measuring systems are classified according to the location of active element, the actuator of the active element, and the location of positive-stiffness element. Several examples of measurement system are described. Then, control methods of achieving zero-compliance are explained for an apparatus using double series magnetic suspension. Finally, measurement results by the developed apparatus are shown. It is confirmed experimentally that the displacement of the detection point is proportional to external force acting on the point of application and high-resolution measurement is possible by the developed system.
Investigation of the Cytotoxic and Antiproliferative Effects of Liposomal Daunorubicin on Human Colorectal Cancer (HCT116) Cell Line
Authors: Alaa Hadi-al-Ward Noorulhuda , Ebrahimi Mehdi , Zare Karizi Shohre
Published: May 2024

Background: The incidence of colorectal cancer is increasing globally. Daunorubicin (DNR), an anthracycline antibiotic, is effective against various cancers. The PI3K/AKT/mTOR signaling pathway is crucial in regulating cell growth and cancer growth. Objectives: This study aims to evaluate the effects of liposomal daunorubicin (Lip-DNR) on cell proliferation and cell death induction in HCT116 cells compared to free daunorubicin. Methods: Lip-DNR was synthesized, and its shape and size were analyzed using FE-SEM imaging. HCT116 cells were treated with Lip-DNR concentrations of 0 (control), 0.125, 0.25, 0.5, 1, and 2 μm for 48 hours to determine the IC50. The effects of free (0.5 μm) and liposomal DNR (IC50 of 0.43 μm) on PI3K mRNA levels were assessed using real-time PCR. The cell cycle was analyzed by flow cytometry. Results: FE-SEM imaging showed that the liposomes are spherical and range from 50 - 100 nm in size. Lip-DNR induced cell death in HCT116 cells in a dose-dependent manner, with 0.5 μm Lip-DNR causing more cell death than an equivalent concentration of free DNR. Analysis of PI3K gene expression showed that DNR decreases PI3K gene transcription in HCT116 cells, with Lip-DNR having a more substantial effect than the free form. Both forms reduced the proportion of G2/M phase cells, but Lip-DNR was more effective at inhibiting cell proliferation in HCT116 cells. Conclusions: DNR inhibits the proliferation of HCT116 cells by downregulating PI3K gene expression and enhancing cell death, with the liposomal form demonstrating stronger effects than the free form.

Published: May 2024

Background: Members of the phylum Verrucomicrobia, especially Akkermensiamuciniphila, have been identified as beneficial gut bacteria. Changes in the gut microbiota are associated with the occurrence of metabolic diseases, such as diabetes, obesity, and irritable bowel syndrome; however, there is conflicting information about their role and changes in colorectal cancer (CRC). Objectives: In the present study, the prevalence of this bacterial phylum in the intestines of individuals with colorectal lesions and healthy controls was investigated. Methods: Mucus samples were obtained from the colons of 69 individuals with colorectal lesions, including CRC and precancerous gut lesions (PCL), and 68 individuals without lesions during colonoscopy. Bacterial DNA was extracted from the mucus samples. A conventional polymerase chain reaction (PCR) assay was performed to detect Verrucomicrobia using a specific 16S rRNA primer. Results: The prevalence of Verrucomicrobia was greater in healthy individuals (75.4%) than in those with either cancer or PCL (59.7%) (P = 0.038). However, there was no significant difference in the presence of these bacteria between the CRC and PCL patient groups. A reverse correlation was observed between the presence of Verrucomicrobia and both chronic constipation (P = 0.001) and anemia (P = 0.048). Conclusions: A decreased frequency of Verrucomicrobia in humans may serve as the basis for the initiation of intestinal changes, resulting in the development of colorectal precancerous and cancerous lesions.

Published: May 2024

Medication adherence is important for people with chronic renal failure (CRF) undergoing hemodialysis. Lowering blood pressure can reduce symptoms and improve the long-term health of hemodialysis patients.  Hypertension is more prevalent and more complex to control in patients with chronic kidney disease and can also be a cause or result of the condition. This study aimed to investigate the association between blood pressure and hemodialysis therapy adherence in patients with renal failure. This study employed a descriptive correlation method to examine patients with CRF who are currently undergoing hemodialysis therapy and have a history of hypertension. In this study, 31 respondents were selected using purposive sampling. Data on medication adherence were collected by questionnaire, while blood pressure readings were used to examine the prevalence of hypertension. The research location is the government hospital in Sukabumi, Indonesia. A chi-square statistical test was used for data analysis. The result showed a relationship between hemodialysis therapy compliance and the incidence of hypertension in patients with chronic renal failure who are undergoing hemodialysis therapy. In patients with chronic renal failure receiving hemodialysis, there is a significant positive correlation between blood pressure and treatment adherence. Research contributes that adherence to the prescribed hemodialysis regimen may play a crucial role in the management and prevention of hypertension in this patient population.

Authors: Ramadhani Tama , Purwadi Wiwik , Polonia Betti Ses Eka , Yusuf Yusuf
Published: May 2024

Strength, toughness, machinability and damping capacity are properties of compacted graphite iron that distinguish the properties between flake graphite cast iron and spheroidal cast iron. The formation of compacted graphite can be set to achieve the required specification. The formation of compacted graphite is started from spheroidal to compacted cast iron. The residual magnesium after magnesium treatment and the solidification ratehave a significant role in the formation of compacted graphite. The high content of residual magnesium can obstruct the graphite plane to grow during the transformation from spheroidal to compacted shape. In addition, the cooling rate of the casting can be controlled by varying the casting thickness. The compacted graphite in the cast iron are characterized according to shape, size ai`nd distribution. The optimum compacted graphite in the cast iron that can be produced has 30 mm of casting thickness with 0.017 % of residual magnesium.

Questionnaires were administered to residents of fourteen selected communities within the game reserve and to the staff of the park. Additionally, focus group discussions were conducted with ten residents from each of the fourteen rural communities. A total of 720 questionnaires were distributed to residents to evaluate the development and benefits received from the establishment of the game reserve, while 250 questionnaires were distributed to the park staff to determine the impact of NGO activities on the communities. Interviews were also conducted with key stakeholders, including ward-heads, village-heads, youths, and women leaders. The findings reveal that the primary developments and benefits received by the game reserve rural communities include the establishment of primary schools, clinics, health centers, construction of roads and culverts, drilling of boreholes and wells, and access to loans for income generation. However, the relationship between farmers and pastoralists is strained, particularly during the dry season when livestock damage crops due to scarce forage. It is recommended that the working relationships between the communities and the game reserve be improved to achieve the overall objectives of conservation programs in Nigeria.

It is difficult to overestimate the importance of the activity and creativity of Arshak Brutyan - a prominent public figure, teacher, folklorist, musician. He dedicated all his life to the cultural prosperity of Shirak and especially the city of Alexandropol. A deeply educated personality, the bearer of advanced national ideas and ideals, Brutyan made an invaluable contribution in advancing the study of folk music and musical and educational life in Armenia. Traditional dance is the most important part of Shirak's folklore. Unfortunately, the movement text of these dances was not recorded at the time, and only dance melodies have reached us. About 63 dance melodies and plays are preserved in the records of the prominent folklorist of the late 19th century Arshak Brutyan, who collected folklore materials mainly in Alexandrapol. His work was an attempt towards a typological characterization of these dances, which are notated in a detailed and in multiple variate manner. In general, ceremonial circle and individual dances are presented, the names of which also feature in the folklore of Javakhk (i.e. Karin) Armenians.
Sosyal Medya ve Kamu Diplomasisi: Türk Devletleri Teşkilatı Perspektifinden Küresel Etkileşim ve İletişim Yönetimi

İnternet teknolojilerindeki değişim ve gelişmeler tüm alanlarda olduğu gibi kamu diplomasisi alanında da yeniliklere neden olmuştur. Bu yenilikler kamu diplomasisinin eski usul ve yöntemlerden, çift yönlü iletişimi içerisinde barındıran, hızlı ve anlık olarak gerçekleşen yeni yöntemlere geçişini zorunlu kılmıştır. Ayrıca bu durum kamu diplomasisinde küresel etkileşim ve iletişim yönetiminin de farklılaşmasına neden olmuştur. Bu farklılaşmanın baş aktörü ise sosyal medya araçlarıdır. Anlık iletişime ve metinsel içeriğe imkân veren ve dünyada en çok kullanılan sosyal medya araçlarının üst sıralarında yer alan X platformu günümüzde kamu diplomasisi bağlamında sıklıkla kullanılmaktadır. Bu çalışmada Türk Devletleri Teşkilatı’nın resmi X hesabı üzerinden paylaşmış olduğu içeriklerin kamu diplomasisi ve küresel iletişim bağlamında incelenmesi amaçlanmıştır. Bu amaç doğrultusunda Türk Devletleri Teşkilatının 01 Kasım-15 Aralık 2023 tarihinde resmi X hesabı üzerinden paylaşmış olduğu 156 adet içerik Maxqda 2022 paket programı kullanılarak içerik analizi yöntemi ile incelenmiştir. Analiz çerçevesinde veriler kodlanarak içeriklerin konu dağılımı, kelime kombinasyonları ve kelime bulutu ortaya çıkartılmıştır. Araştırma sonucunda Teşkilat’ın resmi X hesabını organizasyon, etkinlik, duyuru ve açıklama amacıyla etkin bir şekilde kullandığı tespit edilmiştir. Fakat interaktif iletişim ve etkileşim anlamında bazı eksikliklerin olduğu ve bu tarz paylaşımlara da daha fazla önem verilmesi gerektiği sonucuna varılmıştır.

Objetivo principal: determinar los conocimientos y actitudes hacia la donación de órganos y tejidos de estudiantes de enfermería de una universidad pública de Chile. Metodología: estudio cuantitativo, observacional de corte transversal. La población fue de 266 estudiantes de enfermería. Se aplicó un cuestionario de actitudes y conocimientos respecto de la donación de órganos en Chile.  Resultados principales: un 54,8% no conocía o no sabía acerca de la ley de donación de órganos en Chile y el 73,3% no conocía o no sabía acerca del trámite necesario para no ser donante. Respecto a la actitud el 95,5% estaba a favor de la donación y un 91,4% estaría dispuesto a recibir un órgano o tejido trasplantado. Conclusión principal: estos hallazgos respaldan la necesidad de programas educativos que aborden lagunas de conocimiento y promuevan una cultura de donación de órganos y tejidos más informada y solidaria en la comunidad.
Formulation of defined consortia isolated from sediments of the Chao Phraya and tha Chin rivers for removal of petroleum hydrocarbons
Authors:   , Polrit Duangporn
Published: May 2024

Recently, Thailand faces petroleum contamination in various environments including Chao Phraya and Tha Chin Rivers, which are the main water transportation resulting in oil spill events on the rivers. The oil used in cargo ship is fuel oil which is the mixtures consisting of polycyclic aromatic hydrocarbons (PAHs), aliphatic, asphalthene, and resin. Therefore, this study aimed to formulate the defined bacterial consortium from the selected effective hydrocarbon-degrading and biosurfactant-producing bacteria which having high cell surface hydrophobicity for removal of petroleum oil. In this study, eight strains having different ability to degrade PAHs and aliphatic compounds were obtained and then three high effective bacteria were selected. Mycobacterium sp. J101 had ability to degrade low- and high-molecular weight PAHs and aliphatic compounds. Rhodococcus ruber S103 degraded aliphatic compounds and had high cell surface hydrophobicity and Mycobacterium sp. Y502 degraded high molecular weight PAHs as well as showed potential to produce biosurfactants. These three individual strains, S103, J101, and Y502 could degrade approximately 20% of fuel oil at 2,000 mg L-1 in liquid cultivation within 7 days. While, the defined consortium composed of these three strains degraded fuel oil at 41%. When this defined consortium was immobilized on bio-balls, the immobilized defined consortium had fuel oil removal efficiency in carbon free mineral medium (CFMM) and freshwater from Chao Phraya river by adsorption ability of bio-balls and biodegradation efficiency of defined consortium. When the fuel oil remaining on bio-balls with and without defined consortium was analyzed, it was found that the concentration of fuel oil on bio-ball having defined consortium (816 mg g-1 bio-ball) was lower than the concentration of fuel oil on sterilized bio-ball (1,523 mg g-1 bio-ball). The immobilized defined consortium was able to degrade 46% of fuel oil within 15 days, whereas no degradation was observed in the experiment without bacteria. Furthermore, the result of 16S rRNA gene amplicon sequencing analysis and viable plate count technique found that immobilized defined consortium could survive throughout the experimental period. Consequently, these results indicated that the immobilized defined consortium had a potential to apply for bioremediation of petroleum oil contaminated in the environment.

The research aimed to investigate the contamination and fractionations, and evaluate the ecological risk posed by heavy metals in the e-waste site in Daeng Yai and Ban Pao e-waste dismantling sites, Buriram Province, Thailand. The soil samples were taken from e-waste houses (EW), and e-waste open-burning sites (OB) as representatives of the e-waste sites, while soils from paddy fields (PF), non-e-waste houses, and groundwater wells represented the surrounding area, and the reference site was located 5 km away from the e-waste dismantling site. The soil samples were digested by aqua regia by the microwave digester for total heavy metal determination, and the metals in soils were sequentially extracted following the modified BCR sequential extraction procedure. The contents of As, Cd, Cr, Cu, Mn, Ni, Pb, and Zn were analyzed by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). The concentrations of Cd, Cu, Pb, and Zn in OB were significantly higher (p
