Air pollution in Thailand is regarded as a serious health threat, especially in the northern region. High levels of particulate matter (PM2.5and PM10) are strongly linked to severe health consequences and mortality. This study analyzed the relationship between exposure to ambient concentrations of PM2.5and PM10by using data from the Pollution Control Department of Thailand and the burden of disease due to an increase in the ambient particulate matter concentrations in northern Thailand. This study was conducted using the Life Cycle Assessment methodology considering the human health damage impact category in the ReCiPe 2016 method. The results revealed that the annual average years of life lived with disability from ambient PM2.5in northern Thailand is about 41,372 years, while from PM10it is about 59,064 years per 100,000 population. The number of deaths from lung cancer and cardiopulmonary diseases caused by PM2.5were approximately 0.04% and 0.06% of the population of northern Thailand, respectively. Deaths due to lung cancer and cardiopulmonary diseases caused by PM10, on the other hand, were approximately 0.06% and 0.08%, respectively. The findings expressed the actual severity of the impact of air pollution on human health. It can provide valuable insights for organizations in setting strategies to address air pollution. Organizations can build well-informed strategies and turn them into legal plans by exploiting the study’s findings. This ensures that their efforts to tackle air pollution are successful, in accordance with regulations, and contribute to a healthier, more sustainable future guidelines on appropriate practices of air pollution act/policy linkage with climate change mitigation.

Human excreta are a sustainable, economical source of nutrients, and can be used to produce recycling fertilizer for horticulture by collecting and processing the contents of dry toilets. Herein, we discuss the key categories of risk associated with the main groups of materials commonly found in dry toilets. The study was part of the development of a German product standard for marketable and quality-assured recycling fertilizers from human excreta for use in horticulture. Particular attention is paid to ensuring that the fertilizer is epidemiologically and environmentally harmless and that the quality of the recycling fertilizer is adequate in terms of low pollution and nutrient availability. In sum, the risk of transmissible human pathogens lies within the human excreta, particularly feces;plant materials added during composting are of particular phytosanitary relevance;pharmaceutical residues in excrements and chemical additives are potential sources of pollutants;non-biodegradable contaminants can cause pollution and injury;and the horticultural risks involve mainly the ammonia emission potential and in some cases the salinity effects of urine. These risks can be reduced significantly (i) with education of users around proper operation of dry toilets and the consequences of adding inappropriate waste, (ii) with facilitation of proper use with general waste bins and clear instructions, and importantly (iii) by using modern sanitization and cleaning processes and testing for harmful substances under the guidance of local laws and regulations, ensuring safe and high-quality fertilizers. In conclusion, the benefits of using dry toilet contents to produce fertilizers for use in horticulture are unquestionable. Our analysis highlights the need to support recycling optimization and awareness for the purpose of a sustainable circular economy and to minimize the risk of harm to humans and the environment overall. © 2021, The Author(s).

The increase of microplastic contamination in Vietnam is a growing concern due to various domestic, agricultural, and industrial activities. The use of plastic mulch and sludge application in agricultural farmland, textile production, daily consumer items, cleaning agents, and health/personal care products contribute significantly to the increasing microplastic pollution in the aquatic ecosystem. The concentration of microplastics reported in surface water ranged from 0.35 to 519,000 items m−3, with fibers and fragments being the most prevalent shapes. Notably, the high concentration of microplastics was observed in lakes, canals, and megacities such as Ha Noi and Ho Chi Minh City, which poses potential health risks to the local community via drinking-water supply and food chains. As an emerging pollutant, MPs are the transport vectors for contaminants in environmental matrices that act as a carrier of hazardous pollutants, release toxic compounds, and evenly aggregate/accumulate in biota. Recent studies have reported the presence of microplastics in various marine organisms, including fish and shellfish, highlighting the risk of ingestion of these particles by humans and wildlife. Thus, it is imperative to monitor microplastic contamination in the ecosystem to provide helpful information for the government and local communities. Efforts should be taken to reduce microplastic pollution at the source to minimize potential effects on ecological and health safety. This review paper emphasizes the urgent need for further research on microplastic pollution in Vietnam and highlights potential solutions to mitigate this emerging environmental threat.

In This study, three new surface-modified antibacterial and anticorrosive nanocomposites (zinc Phosphate- Polyvinyl Pyrrolidone, Zinc Phosphate- Polyvinyl Pyrrolidone/Hydroxy Apatite and Zinc Phosphate- Polyvinyl Pyrrolidone/Hydroxy Apatite/Alginate) were synthesized in low-temperature by facile and efficient method. We crosslink Alg with Zn²⁺ and Ca²⁺ to make it insoluble and enhancing of their physical and biological properties (zinc Phosphate- Polyvinyl Pyrrolidone/Hydroxy Apatite/Alginate). Nanocrystals were characterized by (XRD), (FT-IR), (EDX), (SEM) and (TEM). the TEM image showed that the core shell nanocrystal had good dispersion with a particle size of 8–36, 12–38 and 10–45 nm, respectively. Antibacterial rate of the Zinc Phosphate- Polyvinyl Pyrrolidone, Zinc Phosphate- Polyvinyl Pyrrolidone/Hydroxy Apatite and Zinc Phosphate- Polyvinyl Pyrrolidone/Hydroxy Apatite/Alginate NPs reached near 100%. To analyze the EIS results obtained from the equivalent circuits, parameters such as R_ct, CPE_dl, R_f, n, CPE_f, and R_t were extracted. Nyquist diagrams demonstrated that the Zinc Phosphate- Polyvinyl Pyrrolidone/Hydroxy Apatite sample had better protection than the Zinc Phosphate- Polyvinyl Pyrrolidone and Zinc Phosphate- Polyvinyl Pyrrolidone/Hydroxy Apatite/Alginate sample, at all immersion time. The phase angle of the Zinc Phosphate- Polyvinyl Pyrrolidone (-θ 11°/96 h) was a greater value compared with the Zinc Phosphate- Alginate sample (-θ 10°/96 h) and Zinc Phosphate- Polyvinyl Pyrrolidone/Hydroxy Apatite/Alginate (-θ 4.2°/96 h), indicating a transition from capacitive to inductive behavior with longer immersion times. © 2024 The Authors

Large industrial emissions of volatile organic compounds (VOCs) from the petrochemical industry are a critical concern due to their potential carcinogenicity. VOC emissions vary in composition depending on the source and occur in mixtures containing compounds with varying degrees of toxicity. We proposed the use of carcinogenic equivalence (CEQ) and multivariate analysis to identify the major contributors to the carcinogenicity of VOC emissions. This method weights the carcinogenicity of each VOC by using a ratio of its cancer slope factor to that of benzene, providing a carcinogenic equivalence factor (CEF) for each VOC. We strategically selected a petrochemical industrial park in southern Taiwan that embodies the industry's comprehensive nature and serves as a representative example. The CEQs of different emission sources in three years were analyzed and assessed using principal component analysis (PCA) to characterize the major contributing sectors, vendors, sources, and species for the carcinogenicity of VOC emissions. Results showed that while the study site exhibited a 20.7 % (259.8 t) decrease in total VOC emissions in three years, the total CEQ emission only decreased by 4.5 % (15.9 t), highlighting a potential shift in the emitted VOC composition towards more carcinogenic compounds. By calculating CEQ followed by PCA, the important carcinogenic VOC emission sources and key compounds were identified. More importantly, the study compared three approaches: CEQ followed by PCA, PCA followed by CEQ, and PCA only. While the latter two methods prioritized sources based on emission quantities, potentially overlooking less abundant but highly carcinogenic compounds, the CEQ-first approach effectively identified vendors and sources with the most concerning cancer risks. This distinction underscores the importance of selecting the appropriate analysis method based on the desired focus. Our study highlighted how prioritizing CEQ within the analysis framework empowered

Three-dimensional (3D) cell culture is a promising method for preserving the mature functions of cultured cells based on advantageous structural characteristics. Because of the convenience of manufacture, one of the most used 3D cell culture methods is spheroid culture. The successful application of spheroids requires that cells survive inside a structure and engraft at transplantation sites. In this study, we proposed new concept of spheroid formation method containing hyaluronic acid (HA) microparticles. HA microparticles fabricated by an inverse emulsion method with crosslinking reaction of HA showed micro-sized interconnected pore structures. The spheroids containing HA microparticles were uniform in size and showed higher cell migration activity in matrigel. After transplantation of spheroids into the liver of mouse, the spheroids containing HA microparticles showed a higher survival rate and albumin secretion ability than the plain spheroids. Thus, a 3D cell culture system with HA microparticles in spheroids could be a promising strategy to improve the engraftment and efficiency of cell therapy for next-generation regenerative medicine. © 2023, The Authors.

One of the major issues related with impermeable surfaces such as impervious concrete pavement in urban area is the collecting of rain as stormwater runoff, which then moves harmful natural and man-made pollutant into the natural water bodies such as lakes, streams, rivers, etc. This study investigated the effect of pervious concrete containing palm oil kernel shell and seashell on removing dissolved heavy metals contaminants from stormwater runoff. Therefore, mixtures were made, which replaced 6.3-9.5 mm limestone with 25 and 50% of 6.3-9.5 mm and 4.75-6.3 mm of both shells. The specimens were cured in a fog room and void content were tested. Specimens with same void content (23%) are selected to reduce experimental variability from differing void content. Pervious concrete cylinders were loaded in the laboratory with collected stormwater runoff, and concentrations, volumes of influent and effluent evaluated. Ten consecutive storm events of 200 mL in 20 min of rain are simulated to test heavy metal removal performance. The range of heavy metal removal for pervious concrete mixture containing seashell was 37 and 93% which was higher than that of control mixture (39-73%). However, the rate of heavy metal removal for specimens incorporating kernel shell was between 14 and 63% which was lower than that of control mixture. The results showed that the waste materials can be considered as one of the sustainable runoff purification methods, respecting their effective heavy metal removal rate in runoff, as well as the reasonably low cost and consumption when used on the pervious concrete pavement. © 2022, The Authors.

This study aims to understand the willingness of urban communities in Jabodetabek (Jakarta, Bogor, Depok, Tangerang, Bekasi) to move to apartment dwellings, and a study was conducted using a quantitative survey method. The study aimed to analyze the sociodemographic factors influencing the decision to switch to vertical housing. The survey collected data from a sample of individuals representing the entire population in Jabodetabek. The participants in the study were selected from various locations within Jabodetabek, including Jakarta, Bogor, Depok, Tangerang, and Bekasi. These areas were chosen to comprehensively represent the metropolitan region and its urban communities. By including participants from different locations within Jabodetabek, the study aimed to capture individuals' diverse perspectives and experiences in this region. The survey covered a range of sociodemographic factors such as gender, income, education level, marital status, occupancy, and residence ownership. The participants were divided into two groups: those willing to pay for an apartment and those who wereilling to pay for an apartment and those not. By comparing the characteristics of these two groups, the study aimed to identify significant differences and understand the factors influencing the willingness to move to apartment dwellings. The study results showed significant differences in income level, education level, marital status, and occupancy between the two groups. Income level was the most significant factor affecting an individual's willingness to pay for an apartment. Additionally, the perception of better apartment productivity, which includes reduced transportation time and costs associated with work or other business purposes, increased the demand for apartments. The study found that income level was the most significant factor affecting an individual's willingness to pay for an apartment. The perception of better apartment productivity also increased demand for apartments,

A modified chitosan-polyvinyl alcohol (PVA) hydrogel was developed by incorporating Fe3O4 nanoparticles. Four chitosan-Fe3O4 (ChFe) hydrogel types were developed based on chitosan:Fe3O4 ratio as 1:0, 1:1, 1:0.5 and 1:0.25. Batch sorption experiments were conducted with different pH, dosage, kinetics, and isotherms. The exhausted ChFe hydrogels were evaluated for their regeneration and reuse capability with different acids and bases. The best hydrogel for arsenic (V) [As(V)] adsorption was 1:0.5 ratio ChFe hydrogel. The highest As(V) adsorption (89 %) was at pH 4 and the adsorption capacity gradually decreased with increasing solution pH. Within the pH 4–6 range, the hydrogel surface became positively charged due to protonation of –NH2 and –OH groups in the polymer chain and the positive surface attracted H2AsO4− and HAsO42− oxyanions. The experimental kinetic data was well-fitted to the Elovich model (R2 of 0.99) while the Freundlich isotherm model best described the isotherm data (R2 of 0.97). The models predicted chemisorption mechanisms on ChFe hydrogel composites. Electrostatic attractions with –NH3+ and –OH2+, ligand-exchange inner-sphere complexes formation and bidentate corner-sharing (2C) and bidentate edge-sharing (2E) trimetric surface complexes formation have been proposed as the adsorption mechanism of As(V) into ChFe hydrogel. 0.1 M CH3COOH showed the best regeneration pattern with 75, 96, 81, 53 and 43 % of 1st, 2nd, 3rd, 4th and 5th adsorption respectively. Because of this re-usable capability, the As(V) adsorption capacity is not a single value from one adsorption cycle, but a cumulative value of several adsorption cycles and it was 17.39 mg/g for five adsorption cycles. Open for regeneration and reuse, no post-treatment is needed for adsorbent-water separation, allow applications of the ChFe hydrogel composite in a wide range of applications such as water filtration and purification systems. The modification with ChFe further expands the application
