For regulatory purposes, air pollution has been reduced to management of air quality control regions (AQCR), by inventorying pollution sources and identifying the receptors significantly affected. However, beyond being source-dependent, particulate matter can be physically and chemically altered by factors and elements of climate during transport, as they act as local environmental constraints, indirectly modulating the adverse effects of particles on the environment and human health. This case study, at an industrial site in a Brazilian coastal city – Joinville, combines different methodologies to integrate atmospheric dynamics in a strategic risk assessment approach whereby the influence of different wind regimes on environmental and health risks of exposure to PM2.5-bound components, are analysed. Although Joinville AQCR has been prone to stagnation/recirculation events, distinctly different horizontal wind circulation patterns indicate two airsheds within the region. The two sampling sites mirrored these two conditions and as a result we report different PM2.5 mass concentrations, chemical profiles, geo-accumulation, and ecological and human health risks. In addition, feedback mechanisms between the airsheds seem to aggravate the air quality and its effects even under good ventilation conditions. Recognizably, the risks associated with Co, Pb, Ni, Mn, and Zn loadings were extremely high for the environment as well as being the main contributors to elevated non-carcinogenic risks. Meanwhile, higher carcinogenic risks occurred during stagnation/recirculation conditions, with Cr as the major threat. These results highlight the importance of integrating local airshed characteristics into the risk assessment of PM2.5-bound components since they can aggravate air pollution leading to different risks at a granular scale. This new approach to risk assessment can be employed in any city's longer-term development plan since it provides public authorities with a strategic

Effects of refining degree, HwBKP-SwBKP mixing ratio, and the type and the dosage of strength agents on initial wet - web strength were investigated. Two types of strength agents consisting of PAE (polyamideamine-epichlorohydrin)-PVA (polyvinyl alcohol), and PAE-MP (micropolymer) were applied. It was found that the addition of PAE-PVA or PAE-MP strength agents can improve the initial wet-web strength of HwBKP-SwBKP sheets by increasing the interaction between pulp fibers and by improving dewatering efficiency and then the solids content of the wet-web. The PAE-MP strength agent showed superior dewatering efficiency than the PAE-PVA strength agent, resulting in a higher solids content and a higher initial wet-web strength at a given polymer dosage. However, the PAE-PVA strength agent showed higher initial wet-web strength at a given solids content than the PAE-MP strength agent. In addition, increasing the refining degree and increasing the amount of longer fibers in stock resulted in the improved initial wet-web strength of HwBKP-SwBKP sheets. © 2020 Korean Technical Assoc. of the Pulp and Paper Industry.

Despite the high toxicity of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs, or dioxins), the case studies about PCDD/Fs contamination in sediment are still few and its ecological impacts are not fully elucidated. To improve the risk management of PCDD/Fs pollution in sediment, the present study conducted the environmental risk assessment of the brine water storage pond near a chemical plant with high PCDD/Fs pollution potential before and after corrective actions. The results showed the PCDD/Fs accumulation in the fish and crab from the brine water storage pond, and the PCDD/Fs concentrations in biota were all higher than the food safety standard in Taiwan (3.5 pg-TEQ/g). Furthermore, the different indexes showed high degree of pollution including contamination factor (CF), modified degree of contamination (mCd), and pollution index (PI) in the PCDD/Fs polluted sediment. High biological risk indexes such as potential ecological risk index (RI) and risk quotient (RQ) were also observed in the PCDD/Fs contaminated sediment before the corrective actions. After the corrective actions such as institutional/engineering control and remediation, the CF, mCd, and PI decreased by 20–41%. The RI and RQ were also decreased by 41–56%. In conclusion, the corrective actions applied in the present study could help decrease the pollution and ecological risk of PCDD/Fs in the polluted sediment of the study site, which might further decrease the environmental risk to an acceptable level for the stakeholders if keeping implementation of the corrective actions. © 2022, The Authors.

The study aimed to evaluate the impact of occupational noise on hearing loss among healthcare workers using audiometry. A longitudinal study was conducted with a six-month follow-up period in a hospital with 21 participants, divided into high-noise-exposure (HNE) and low-noise-exposure (LNE) groups. Mean noise levels were higher in the HNE group (70.4 ± 4.5 dBA), and hearing loss was measured using pure-tone audiometry at baseline and follow-up. The HNE group had significantly higher mean threshold levels at frequencies of 0.25 kHz, 0.5 kHz, 4.0 kHz, and an average of 0.5, 1, 2, and 4 kHz (all p-values © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

Rare earth elements (REEs) are exploited for global use in manufacturing. Such activities result in their release into the environment and the transformation into more stable phosphate deposition. The objective of this study was to evaluate molecular and behavioral changes of zebrafish exposed to the synthesized terbium phosphate (TbPO4) at concentrations of 10, 20, and 50 mg/L and to determine its potential for neurotoxicity. Metabolomic profiling and assessment of transcripts and proteins were conducted to uncover the molecular mechanisms underlying TbPO4 with emphasis on neurotransmitter systems. Exposure to 20 mg/L TbPO4 induced larval hyperactivity and perturbed the cholinergic system in zebrafish. Based on metabolomics, dopamine (DA), serotonin (5-HT), and many of their precursors and metabolites were decreased in abundance by TbPO4. In addition, the expression levels of transcripts related to the synthesis, transport, receptor binding, and metabolism of DA and 5-HT were analyzed at the mRNA and protein levels. Transcript and protein levels for tyrosine hydroxylase (TH), the rate-limiting enzyme for DA synthesis, were down-regulated in larval fish. Monoamine oxidase (MAO), an enzyme that catabolizes monoamines DA and 5-HT, also reduced mRNA abundance. We hypothesize that DA synthesis and monoamine metabolism are associated with behavioral alterations. In addition, a mechanism for the disruption of neurotransmitter systems by TbPO4 may be the apoptosis of neurons. This study elucidates putative mechanisms and exposure risks to wildlife and humans by characterizing phosphatic REE-induced neurotoxicity in developing zebrafish. © 2023, The Authors.

This study focuses on developing fiber-reinforced geopolymer concrete (GPC) for 3D printing, utilizing construction waste materials and polypropylene fibers. The GPC, reinforced with 0.8%, 1.0%, and 1.2% polypropylene fibers, underwent comprehensive testing, including rheological, mechanical, and microstructural analyses for lab-cast and 3D-printed samples. Results indicate that the 0.8% polypropylene fibers enhance flexural and tensile strengths by 8.2% and 71.7%, respectively, albeit decreasing compressive strength by 26.2%. Higher polypropylene percentages led to adverse effects. Microscopic analysis revealed voids and signs of incomplete hydration. The study emphasizes optimizing water content, using longer polypropylene fibers and highlights GPC’s suitability for 3D-printing structural components. © 2023, The Authors. All rights reserved.
