Employing a pilot-scale scrubber packed with a Rashing ring randomly, where experimentally examined the absorption performance of carbon dioxide capturing by using an aqueous solvent of primary and poly alkanol amines; the investigations on carbon dioxide capturing were carried out at atmospheric pressure (1 atm), us-ing simulated feed gas of carbon dioxide balanced with nitrogen. Monoethanolamine, Triethylenetetramine, and Diethylenetriamine are the primary and poly alkanol amine absorbents examined for this work. The impact of operating conditions, including amine inlet concentrations, liquid flow rates, gas flow rate, lean amine loading, inlet carbon dioxide concentration, absorbent temperature, and alkanol amine type, were examined according to the two-film concept. Regarding the removal of carbon dioxide efficiency and volumetric mass transfer coefficient based on the gas side, the absorption performance was presented. A lab-scale investigation revealed that employing DETA absorbent possesses higher carbon dioxide removal efficiency of up to 28.9% and a higher coefficient of mass transfer of up to 165.7% in comparison to conventional MEA absorbent while employing TETA absorbent possesses higher carbon dioxide removal efficiency of up to 18.86% and higher coefficient of mass transfer of up to 69.64% in comparison to the conventional MEA absorbent. Based on these findings, it is reasonable to assume that DETA would serve as an efficient chemical absorbent for the removal of carbon dioxide.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134996571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of large-scale energy crop monocultures on soil biodiversity is poorly understood and requires long-term monitoring. Due to their specific lifestyle, Lumbricidae, known as “ecosystem engineers”, have found application in biomonitoring of the soil environment. This study aimed to evaluate the qualitative and quantitative structure of Lumbricidae in annual rapeseed ( Brassica napus L.) and perennial willow ( Salix viminalis L.) crops for energy purposes, with a permanent grassland as a control site. The research was conducted on the territory of the Podkarpackie Agricultural Advisory Center in Boguchwała (southeastern Poland). Earthworms were obtained by hand sorting soil blocks of 25×25×25 cm and a 0.4% formalin solution was used to extract individuals from deeper soil layers. There were no differences in the species composition of Lumbricidae between the analyzed crops. Five species of earthworms, Dendrodrilus rubidus tenius , Lumbricus rubelllus, Aporrectodea caliginosa, A. rosea, and L. terrestris, were found at each study site . Rapeseed had the lowest density (17.26 ± 9.16 ind·m -2 ) and biomass (5.93 ± 2.42 g·m -2 ) of Lumbricidae (p < 0.05). On sites with willow and permanent grassland, density and biomass of Lumbricidae were similar (69.15 ± 28.99 ind·m -2 ; 26.55 ± 9.67 g·m -2 and 54.04 ± 22.93 ind·m -2 ; 20.03 ± 7.99 g·m -2 , respectively (p > 0.05). The study demonstrated the beneficial effect of perennial willow cultivation on the quantitative structure of earthworm communities. Only long-term biomonitoring will make it possible to determine the real impact of energy crops on invertebrate assemblages and their appropriate management to promote biodiversity.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134996039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aims to conduct a comprehensive health risk assessment of heavy metals exposure via inhalation, with a focus on submicron particles (PM 1 ), in two major cities of Poland - Warsaw and Zabrze. These cities were selected due to their distinct levels of urbanization and industrialization. Non-carcinogenic and carcinogenic risks assessment was performed for children and adults. The carcinogenic risk was evaluated for As, Cd, Cr(VI), Ni, Pb, and Co, classified as carcinogens, the non-carcinogenic risk evaluation encompassed a broader range of metals, including V, Mn, Cu, Zn, and Mg, aiming to comprehensively understand health exposure. The results highlight elevated carcinogenic risk in Zabrze, primarily linked to industrial activi - ties and ongoing emissions. Notably, Ni, As, and Cr(VI) exceed safe limits, underscoring the need for targeted interventions. Moreover, non-carcinogenic risks reveal Zabrze’s heightened respiratory health risks, compared to Warsaw. Despite Warsaw’s lower non-carcinogenic risk values, both cities recorded Ni and Mg concentrations ex - ceeding safe limits. This indicates that Zabrze faces higher health risks from heavy metal exposure due to ongoing pollution sources. In contrast, Warsaw, the capital city and a major urban centre, demonstrates better air quality but still requires continuous monitoring and pollution control measures.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"355 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134996572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current trend tends towards autonomous systems. Among these systems are Floating treatment wetlands. The objective of this study was to evaluate the evapotranspiration and the performances of two emerging plants; Cyperus papyrus and Typha latifolia . The ex - perimental device was composed of three test tanks whose dimensions were: length = 1 m, width = 1 m and water height = 0.85 m – two tanks with emerging plants ( Cyperus papyrus and Typha latifolia ) and a control tank without vegetation. The monitoring of the evolution of plant evapotranspiration and the evaporation of the control tank for different periods and temperatures showed that the volumes of water lost were respectively for Cyperus papyrus , Typha latifolia and control tank: (1) 130 liters, 230 liters and 5 liters for two days at an average temperature of 26.3 °C; (2) 125 liters, 150 liters and 0 liters for two days at an average temperature of 26.7 °C; (3) 240 liters, 280 liters and 5 liters for three days at an average temperature of 27.3 °C; (4) 140 liters, 260 liters and 10 liters for two days at an average temperature of 26 °C; (5) 140 liters, 240 liters and 5 liters for two days at an average temperature of 27.3 °C; (6) 260 liters, 550 liters and 10 liters for four days at an average temperature of 28.6 °C. It turned out that the presence of plants as well as the temperature and the retention time in the tanks have a impact on the loss of water and more precisely those with emerging macrophytes. The present study has shown that the floating treatment wetlands planted with Cyperus papyrus and Typha latifolia can be used for wastewater treat-ment. Indeed, the removal efficiency in terms of COD, BOD 5 and SS were respectively: 76%, 75.3% and 95.90% for Cyperus papyrus and 70.45%, 66.5% and 93.70% for Typha latifolia .","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134996037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A huge quantity of effluents is produced during the process. However, toxicity from synthetic dyes has become a cause of severe environment concern. Chlorophenols are mostly present in synthetic dyes which are proven carcinogenic and therefore undesirable. A number of techniques were used to remove p-Chlorophenol up to the ZDHC MRSL limit. However, none of them found to be up to mark. Fenton oxidation process was selected for its suitability to degrade the p-Chlorophenol up to 5 ppm or less from the textile wet processing industry effluent. In the present study cotton fiber was selected, as medium considering its common use in textile industry. The impact of Ferrous ion (Fe +2 ), Hydrogen peroxide (H 2 O 2 ) and pH on the removal of p-Chlorophenol was examined. The Box-Behnken Design (BBD) of (RSM) was employed to achieve optimum desirable condition for the removal of p-Chlorophenol from effluent. A quadratic model is suggested to relate the independent variables for maximum removal of p-Chlorophenol at the optimal process condition. Results suggest that removal efficiency under the optimum condition [Fe +2 ] = 6.5×10 -3 M, [H 2 O 2 ] = 2.9×10 -2 M, and [pH] = 3.5 was >90% in 15 minutes. It can be summarized that Fenton oxidation process as the promising potential for removal of p-Chlorophenol from textile wet processing industry effluent. This research work helps to address for the general knowledge gap in the textile wet processing industry effluent treatment and provide a plate form for further research.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"358 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134996569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In urbanised areas, there are many sources of dust emissions, but one of the main ones is road traffic. Investigating and assessing the physical and chemical properties of road dust and, more specifically, dust collected from surface courses is one way of providing an op - portunity not only to identify the contribution of the emitters concerned to the formation of dust air pollution in the vicinity of roads but above all the environmental risks associated with traffic emissions. The study aimed to analyse the elemental composition of dust with a fraction <0.1 mm, collected from asphalt and concrete roads char - acterised by the highest technical and service parameters in Poland. The samples were analysed using a Shimadzu EDX 7000 energy-dispersive X-ray fluorescence spectrometer, then the results were statistically analysed using the t-Welch test, and the enrichment factors EF were determined. It was shown that road dust with a grain size of less than 0.1 mm collected from asphalt surface course was extremely highly enriched in Cu, Cr, Pb and S, while that from the concrete surface course was enriched in Zn and Zr, indicating a strong anthropogenic origin of these elements; exhaust gases were identified as their source. Irrespective of the type of surface course, very high dust enrichment occurs for Ca, Mn, Ni, S, Ti and Y. These elements may originate from the abrasion process of vehicle tyres. For road dust collected from both road types, the most similar EF values were found for Fe, K, Mn, Si, Sr and Ti. The source of these elements is most likely the roadside soil. It follows that the type of road surface is not the main determinant of the composition of road dust with a fraction <0.1 mm.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"357 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134996570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
