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

The Cantang Grouper (Epinephelus fuscoguttatus-lanceoulatus) is a mating of the female Tiger Grouper fish (Epinephelus fuscoguttatus) and the male Kertang grouper fish (Epinephelus lanceoulatus). However, in farming activities, the Cantang Grouper fish can be affected by a VNN infection. One way to deal with the VNN infection is by giving recombinant nano-vaccine from the microalga Chlorella Vulgaris. This study aims to determine the effect of recombinant nano-vaccine administration of the microalgae Chlorella Vulgaris on the growth of the fish weight, length, and eye tissue in the Cantang grouper fish (Epinephelus fuscoguttatus lanceolatus) infected with Viral Nervous Necrosis (VNN). The method used in this study is experimental. The test results showed that the administration of the recombinant C. vulgaris (p-PerCv) vaccine affected the growth in length and weight of the Cantang grouper, this was because the growth in length and weight of its from the treatment group was significantly different from the control group (0.039<0.05). Known by the ANOVA test and also has a different effect on the level of damage to eye tissue both damage to hypertrophy, vacuolization, and necrosis. The results of the Tukey test showed that the treatment that had a significant effect was the T1 treatment (treatment of healthy fish +33l of recombinant C. vulgaris vaccine (p-PerCv) +8.5l of Chitosan nanoparticles).

The existence of extractive activities around the river has a negative impact on the quality of river water. This study aims to provide an overview of water quality characteristics and water quality status of Bengkulu River and Nelas River in Bengkulu Province. The data used is river quality monitoring conducted by the Environment and Forestry Service of Bengkulu Province from 2014 to 2019. Measurements are carried out twice a year representing, the dry season (March to June) and the rainy season (September to December). The observation stations representing upstream, middle and downstream of rivers conditions. The parameters observed were physical, chemical, and biological parameters. The water quality status is determined using the Storet Index. The results show that both rivers have Storet Index >-31. It means that these river water are heavily polluted. Parameters that have exceeded the water quality standard are TSS, DO, BOD, COD, Fe, Mn, Cu, and total coliform. The river water quality parameters, especially heavy metals, may be caused by open land being washed and carried into the river body. The existence of population and animal activities as well as industrial waste outlets at upstream also affect the decline of river water quality.

The growing use of synthetic chemical compounds/substances in vector control of mosquitoes, associated with their adverse effects on the environment and non-target organisms, has demanded the development of eco-friendly alternatives. In this context, this study aimed to evaluate the larvicidal action of different cellulose microcrystalline (CMs) concentrations and investigate their toxicity mechanisms in Culex quinquefasciatus fourth instar larvae as a model species. Probit analysis revealed that the median lethal concentrations (LC50) for 24 h and 36 h exposure were 100 and 58.29 mg/L, respectively. We also showed that such concentrations induced a redox imbalance in the larvae, marked by an increase in the production of reactive oxygen species (ROS) and thiobarbituric acid reactive substances (TBARS), as well as a reduction in the activity of superoxide dismutase (SOD) and catalase (CAT). Furthermore, different alterations in the external morphology of the larvae were associated with the ingestion of CMs. On the other hand, exposure of adult zebrafish (Danio rerio) to LC5024h and LC5036h for seven days did not induce any behavioral changes or alterations mutagenic, genotoxic, biochemical, or in the pro- and anti-inflammatory response. Thus, taken together, our study demonstrates for the first time that the use of CMs can constitute a promising strategy in the control of C. quinquefasciatus larvae, combining insecticidal efficiency with an "eco-friendly" approach in the fight against an important mosquito vector of several human diseases. © 2023, The Authors.

Biomass is an organic substance widely available in nature as a fresh or a waste material considered renewable energy that aligns with the zero-carbon scheme to reduce the dependency on fossil fuels. However, after conversion, biomass's physical or chemical properties highly affect biofuel characteristics. A variety of instruments can be used to figure out biofuel reactivity. Considering commonly adopted instruments, thermogravimetric analysis (TGA) is a simple, fast, and efficient way to determine biofuel properties and reactivity. The TGA method has the capability to analyze the biofuel properties (proximate analysis: moisture, volatile matter, fixed carbon, and ash) and combustion features of biomass (such as ignition, reactivity, etc). Most importantly, the TG curvatures (TGA and DTG) reveal the behavior of the biofuel during the thermodegradation process. As a consequence, the quality and quantity analyses on the biofuel properties and reactivity can be investigated comprehensively. Moreover, some TGA integration with artificial intelligence (AI) has been studied to better understand biofuel management and technology for future development. The outcome for the TGA-AI integration may obtain an excellent result with the fit quality value R 2 >95 %. This study aims to comprehensively review relevant research using TGA to analyze the lignocellulosic biofuel properties and reactivity. Moreover, the discussion in this study is extended to perspective, challenges, and future work.

Groundwater quality assessment is critical for sustainable water resource management, especially in hyperarid regions like Adrar, Algeria, where data scarcity and environmental challenges hinder traditional monitoring methods. This study explores the application of three Few-Shot Learning (FSL) algorithms: Prototypical Networks, Siamese Networks, and Matching Networks, for groundwater quality classification using limited datasets. The dataset comprises 166 groundwater samples from the Adrar region, characterized by five quality classes: “Excellent,” “Very Good,” “Good,” “Satisfactory,” and “Unsatisfactory.” Results demonstrate that Prototypical Networks outperform other FSL algorithms, achieving 93 % accuracy with 10 support samples per class, while Siamese and Matching Networks achieve 90 % and 88 % accuracy, respectively. The study highlights the potential of FSL in addressing data scarcity, offering a cost-effective and efficient approach for groundwater quality assessment in data-scarce regions. The findings underscore the importance of FSL in complementing traditional methods, particularly in hyper arid areas where data collection is challenging.

IOP Conference Series: Earth and Environmental Science 2022年第1期950卷

作者： Ansahar S R P Sitorus H Hardjomidjojo E I K Putri Natural Resources and Environmental Management Science Study Program Graduate School of IPB University West Java Indonesia Department of Engineering Faculty of Mining Enginering Kutai Kartanegara University Kutai Kertanegara District Kalimantan Timur Province Indonesia IPB University West Java Indonesia

The characteristics of coal surface mining activity are vulnerable to environmental degradation due to soil excavation, although only causing a lower risk in worker's incidence and economically beneficial as requiring a lower cost than the underground mining method. This study aimed to analyze the types of post-mining land use worth developing for the local community's livelihood around the post-mining land on the concession of PT Anugerah Bara Kaltim (ABK) in Kutai Kertanegara District, Kalimantan Timur Province. The method used was a cost-benefit analysis (CBA). The analysis results indicate that the pepper plant cultivation on the post-mining land within six years produces Net Present Value (NPV) at Rp 49,484,637.00, Benefit/Cost (B/C) Ratio at 1.347, Net B/C Ratio at 2.56, and Internal Rate Return (IRR) at 39.20%. Meanwhile, rice plant cultivation stimulated within six years produces NPV at Rp 8,653,754.00, B/C Ratio at 1.035, Net B/C ratio at 1.3871, IRR at 8,50%. The economic analysis results based on all indicators: NPV, B/C, net B/C, and IRR, demonstrate that the pepper and rice plant cultivation activities are feasible in the coal post-mining land.
