ABSTRACT With rapid urbanisation and industrialisation, the human race is experiencing a massive decline in air, water, and soil quality. The quest for proper adsorption of increasing levels of carbon dioxide is still a topic of concern globally. The numerous carbonaceous and non-carbonaceous solid adsorbents can be employed for adsorbing CO2 gas via the physisorption and chemisorption techniques. This mini-review critically discusses the most frequently used solid adsorbents, such as activated carbon, zeolites, and metal–organic frameworks. Activated carbon is widely used owing to its low cost and easy availability. However, zeolites and metal–organic frameworks show much higher adsorption capacity, thus making them promising adsorbents for carbon capture. Therefore, the ongoing and future research aims at finding cheaper routes for organic linker synthesis for economical, better, and more efficient carbon-capturing adsorbent and metal–organic frameworks that contain the potential to build this gap.

ABSTRACT Microbial fuel cell (MFC) technology with decarbonization and denitrification is considered to be advantageous in treating wastewater with a low carbon-to-nitrogen ratio. In this study, MFC was treated with different concentrations of nitrate-nitrogen. The MFC technology revealed significant treatment advantages when compared to both abiotic electrode treatment and microbial treatment only. The best treatment effect was recorded when the MFC's nitrate-nitrogen ( ) concentration was 414 mg/L. The running of the MFC system showed that it produced a stable output voltage of up to 0.17 V within 160 h. It showed a power density of up to 40.18 mW/m2, 1.58 times M1 (138 mg/L, 25.49 mW/m2), and 4.48 times non-biological electrode. The removal rate of was 97.48%, but the lack of anode electron supply resulted in the incomplete reduction of nitrate-nitrogen and accumulation of nitritenitrogen. Nitrate-nitrogen concentration in the study had no significant impact on microbial population diversity. However, the relative abundance of Proteobacteria increased from 47.3% to 65.4% when concentration increased from 138 to 414 mg/L. Burkholderiales, Hydrogenophilales, and Rhodocyclales were the main denitrifying bacteria. These results demonstrate promise in supporting the development of microbial cathode denitrification.

ABSTRACT Previous studies have shown that certain areas in the territory of the Republic of Macedonia are affected by anthropogenic input of large amounts of various chemical elements into the soil. The area in the vicinity of the Toranica lead and zinc mine near the town of Kriva Palanka, North Macedonia, was studied for the lithogenic and anthropogenic distribution of seventeen elements (Al, As, Ba, Ca, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Sr, V and Zn). Automorphic soil samples (topsoil and subsoil) as well as alluvial sediments and fluvisol samples were collected from the Kriva River basin. Elemental contents were determined by inductively coupled plasma – atomic emission spectrometry (ICP-AES). Data processing was performed using combinations of multivariate statistical methods (factor analysis and cluster analysis). The summarised data for topsoil and subsoil samples show strong correlations between the element distributions in topsoil samples and subsoil samples along the Kriva River basin. Anthropogenic influences were observed in Zone 1 (the area affected by hydrothermal Pb-Zn exploitation). The topsoil layer was affected by enrichment with As, Mn, Pb, and Zn up to 220, 3400, 1700 and 1100 mg/kg, respectively.

ABSTRACT In this study, eighteen surficial sediments were collected from two shallow lagoons of the Red Sea, King Saudi Arabia (Al-Shaibah and Al-Budhia lagoons), and analyzed for their grain size, CaCO3, and organic matter (O.M.) contents. The concentration of total phosphorus (TP), Organic-P (OP), and Inorganic-P (IP) were determined. In addition, Phosphorus bioavailability was also investigated by a sequential extraction procedure. The results of the current study showed variation in the levels of total phosphorus and the organic and inorganic form (TP, IP, OP). Al-Shaibah lagoon showed higher TP contents (274.78–389.24 and 265.91 ± 29.03 µgg-1) more than Al-Budhia lagoon (227.25–318.55 and 265.91 ± 29.03 µgg-1). The distribution of phosphorus bioavailability concentrations in the studied fractions in Al-Shaibah lagoon sediments was increased in the following order: hot H2O-P (0.10–0.25µgg−1) < NaHCO3-P (1.85–3.11 µgg−1) < exchangeable fraction (NH4Cl-P; 2.64–10.64 µgg−1) < Fe and Al-associated phosphorus (NaOH-P; 29.67–7.32 µgg−1). A similar order was observed in the Al-Budhia lagoon with slight differences in its content. The different fractions of the contribution of phosphorous bioavailability from the Total-P concentration were recorded as: NaOH-P (14.63–18.62%) >> NH4Cl-P (2.11–1.99%) > NaHCO3-P (0.75–1.04%) >H2O-P (0.05–0.09%). The phosphorus concentrations in the HCl-P fraction (calcium-associated phosphate/apatite) represent 32.67–59.60% of the total phosphorus in lagoon sediments.

ABSTRACT This work assesses the efficiency of biological processes in reducing leachate toxicity, using tests of phytotoxicity, cytotoxicity and heavy metals assay. Concerning metal load of raw leachate, iron is the most abundant with a value of 77.23 mg/L; combined treatment is most effective in reducing metals with abatement rates of: Al (94.96%), Fe (99.23%), Pb (90.53%), Sn (90.25%) and Zn (90.43%). The phytotoxicity of raw leachate is total against all tested seeds, this phytotoxicity was decreased after treatment with SBR, and the germination indices are between 3.60%−65.36%, 0.25%−39.99% and 5.36%−35.55% respectively for Daucus carota, Lactuca sativa and Hordeum vulgare seeds. Leachate treated with the combined treatment exhibits no inhibition of germination even at concentrations of 100%. Regarding cytotoxicity assessed via Brine Shrimp test, raw leachates were cytotoxic killing all Artemia salina larvae even at low concentration of 1%. After the treatments, cytotoxicity of leachate was decreased especially in leachate treated by SBR and combination with inhibition percentages up to 16.66%. The experimental results obtained were confirmed using PCA which showed that the SBR and combination treatments have common purification characteristics and also the inverse correlation between heavy metal concentrations and germination indices indicate that these metals are involved in leachate toxicity.

ABSTRACT The aim of this study was to examine the effect of maize straw biochar (MSB), cotton residue biochar (CRB) and wheat straw biochar (WSB) application (1.5% wt.) on Cd immobilisation in a light-textured calcareous soil with varying levels of Cd-contamination. Application of all three crop residue biochars were found to significantly enhance the immobilisation of Cd in the sandy loam calcareous soil. Cotton residue biochar was by far the most effective biochar for reducing the more labile soluble and exchangeable (WsEx-Cd) (−44.4%) and carbonate (Car-Cd) (−44.7%) Cd fractions and increasing the less available residual (Res-Cd) fraction (+82.9%) compared to the maize and wheat straw biochars (WsEx-Cd: −18.8–20.3%; Car-Cd: −27.1–29.0%; Res-Cd: +43.8–44.8%). Application of CRB also significantly reduced EDTA-extractable Cd by 45–52%, and specifically reduced the two-first-order kinetic model Q1 parameter (−55.3%) and increased the Q3 parameter (26.1%). The greater effectiveness of the CRB was associated with its substantially higher C and lower ash content compared to the other crop residue biochars. Results of this study demonstrate the potential use of crop residue biochars, especially cotton residue biochar, in remediation of Cd contaminated calcareous soils.

ABSTRACT Auto-mechanic service workshops in Nigeria tend to spill waste lubricating oil into the soil. The waste lubricating oil is washed into nearby streams by runoff leading to water pollution. The current study is aimed at assessing the performance and response of P. stratiotes in the remediation of water contaminated with waste lubricating oil. The contaminated water used for this study is a product of an artificial spillage of surface water and different volumes (30, 60, 90, 120 and 150 mL) of waste lubricating oil. The reduction efficiency, biotranslocation, bioconcentration factor, relative growth rate and the enzymatic and non-enzymatic response of P. stratiotes were determined. The results show that the efficiency of P. stratiotes in improving the quality of the contaminated water increases with an increase in the retention time of P. stratiotes but decreases with an increase in the volume of used lubricating oil. The result also shows an increase in the growth rate of P. stratiotes with increasing retention time but a decrease with an increased volume of used engine oil. The study also shows that P. stratiotes can counteract any effect induced by the pollutants in the contaminated water through antioxidant and non-antioxidant responses.

ABSTRACT The removal of lead from water and wastewater is a serious term for protecting the public and the environmental. Herein, an agriculture waste of sorghum bagasse modified with NaOH was used to adsorb Pb(II) from an aqueous solution. The modified sorghum bagasse (MSB) was characterised by field emission scanning electron microscopy (FESEM), Brunauer–Emmett–Teller (BET) method and Fourier transform infrared spectroscopy (FTIR). MSB with NaOH shows smoother, increasing porosity and pore size (mesopore). In a batch system, the parameter adsorption was investigated. The adsorption of Pb(II) by the adsorbents was optimum at pH 5.0, contact time: 15 min, adsorbent dosage: 6 g L−1 and initial concentration: 80 mg L−1. The pseudo second-order model was suitable to describe the kinetic of the process with the diffusion model of the Elovich model. Meanwhile, the adsorption isotherm model was suitable with the Langmuir model and gives a maximum adsorption capacity (qmax) 12.29 mg g−1. The Gibbs free energy was negative, and the enthalpy was negative, indicating the adsorption was a spontaneous and exothermic process. These results indicated that the MSB had potentially become an efficient, sustainable and low-cost adsorbent for Pb(II) uptake from an aqueous solution.
从水和废水中去除铅是保护公众和环境的一个重要术语。本研究以农业废弃物高粱甘蔗渣为原料，经氢氧化钠改性后，用于吸附水溶液中的铅(II)。采用场发射扫描电镜(FESEM)、布鲁诺尔-埃米特-泰勒(BET)法和傅里叶变换红外光谱(FTIR)对改性高粱甘蔗渣(MSB)进行了表征。添加NaOH的MSB更光滑，孔隙率和孔径(中孔)增大。在间歇式系统中，研究了吸附参数。在pH为5.0、接触时间为15 min、吸附剂投加量为6 g L−1、初始浓度为80 mg L−1时，吸附剂对Pb(II)的吸附效果最佳。拟二阶模型适合于用Elovich模型的扩散模型来描述过程的动力学。吸附等温线模型与Langmuir模型吻合，最大吸附量(qmax)为12.29 mg g−1。吉布斯自由能为负，焓为负，说明吸附过程为自发放热过程。这些结果表明，MSB有潜力成为一种高效、可持续和低成本的水溶液中铅(II)吸附剂。

The pseudo second-order model was suitable to describe the kinetic of the process with the diffusion model of the Elovich model. Meanwhile, the adsorption isotherm model was suitable with the Langmuir model and gives a maximum adsorption capacity (qmax) 12.29 mg g−1. The Gibbs free energy was negative, and the enthalpy was negative, indicating the adsorption was a spontaneous and exothermic process. These results indicated that the MSB had potentially become an efficient, sustainable and low-cost adsorbent for Pb(II) uptake from an aqueous solution.","PeriodicalId":9960,"journal":{"name":"Chemistry and Ecology","volume":"39 1","pages":"506 - 524"},"PeriodicalIF":2.5,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46649873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Efficient bioremediation technology has drawn extensive attention from scholars due to the serious damage caused by heavy metals (HMs) to the environment. This study explored the remediation potential and mechanisms of the S. pasteurii strain in alleviating toxicity of Cd and Pb in tailings. The results showed that the decrease in DTPA-Cd and -Pb was associated with the transfer of exchangeable HMs to carbonate-bound HMs in bacteria-treated tailings. Biomineralization, extracellular adsorption, and intracellular accumulation were observed to result in removal rates above 95% for HMs in tailings solution. Mineralisation products driven-urease were identified as carbonate minerals, including otavite CdCO3, cerussite PbCO3 and hydrocerussite Pb3(CO3)2(OH)2. However, the increased Km in the urease kinetics study indicated that HMs reduced urease activity and biomineralization by minimum inhibitory concentrations (Cd 0.5 mM and Pb 40 mM). The functional groups (-OH, -NH2, -COOH and -PO4 3-) on the bacterial surface were involved in immobilising HMs, while the biosorption capacity (qm) was inhibited by metal ions (Pb2+ > Cd2+) according to Langmuir sorption isotherm. In conclusion, the biomineralization-adsorption of S. pasteurii was the mainstay for stabilising Cd and Pb in tailings, and the contribution of biomineralization was found to be much higher than that of biosorption.

ABSTRACT This study determined the LC50-24 h value of sodium pyrithione (NaPT) on Cyprinus carpio at 102.7643 µg/L. Then, 60 healthy fish were randomly allocated into 6 exposure groups, each receiving varying levels of NaPT for different durations (control goup = 0% µg/L NaPT for 24 and 96 h; NaPT-10 = 10% of the LC50-24 h dose of NaPT for 24 and 96 h; NaPT-20 = 20% of the LC50-24 h dose of NaPT for 24 and 96 h). As a result, the increase in malondialdehyde (MDA) levels and the decrease in catalase (CAT), glutathione peroxidase (GSH-Px), and superoxide dismutase (SOD) activities in the gill and liver tissue in both duration and dose groups were found to be statistically significant. In addition, NaPT increased serum tumour necrosis factor (TNF-α), interleukin-1 beta (IL-1β), interleukin-6 (IL-6) levels in both dose groups for both durations. The results revealed that NaPT exposure caused shortening of gill tissue lamellae and vacuolisation (separation) of the secondary lamellar epithelium. Likewise, NaPT exposure was responsible for vacuolisation and hepatocellular degeneration in liver tissue in hepatocytes. In conclusion, the toxicity study, antioxidant enzyme activities, cytokine immune response, and histopathological results indicate that NaPT has a toxic effect on the carp.
