Abstract The issue of agricultural non-point source pollution has attracted the attention of the state and the masse. In the non-point source pollution control organizations which composed of the governments, farmers and fertiliser sellers, due to the characteristics of rational economic body, the phenomenon of ”market failure” and ”government failure” may occur in the process of non-point source pollution control. In this paper, the author applies game theory to analyse the main behaviour characteristics of the three main bodies, and constructs the incomplete information dynamic game model that the government, farmers and fertiliser sellers participate in. According to the results of the equilibrium solution of the Haysani Axiom model, it is found that the decisions made by the three bodies of the government, the fertiliser seller and the farmer in the behaviour choice stage have a great influence on the behaviour choice of the other two bodies, and the process of each strategy choice by the three bodies is a dynamic game process of the three bodies. Finally, according to the main influencing factors reflected in the equilibrium solution, proposed the related non-point source pollution control countermeasure suggestion to the government main body.
农业面源污染问题已引起国家和社会各界的高度重视。在由政府、农民和化肥销售商组成的非点源污染控制组织中,由于理性经济主体的特点,在非点源污染控制过程中可能会出现“市场失灵”和“政府失灵”的现象。本文运用博弈论分析了三个主体的主要行为特征,构建了政府、农民和化肥销售者三方参与的不完全信息动态博弈模型。根据Haysani公理模型均衡解的结果,发现政府、化肥销售者和农民这三个主体在行为选择阶段的决策对其他两个主体的行为选择有很大的影响,并且这三个主体的每一个策略选择的过程都是三个主体的动态博弈过程。最后,根据均衡解中体现的主要影响因素,向政府主体提出了相关的非点源污染控制对策建议。

Abstract Polycyclic aromatic hydrocarbons (PAHs) are formed from anthropogenic activities, i.e. industrial emissions, incomplete combustion of petroleum, coal and other fossil fuels and other industrial and domestic activities. Research areas of this study are four representative locations in the industrial complex, in the city of Banja Luka, Republic of Srpska, Bosnia and Herzegovina. The main objective of the paper is to determine the ecological risk and to assess probable sources of PAHs contamination in soil and groundwater. The results of this study reflect the effects of coal combustion (pyrogenic origin), petrogenic and biomass origin and may provide basic data for the remediation of PAHs in the location. The ecological risk in soil (at depths of 30, 100, 200, 300 and 400 cm) and groundwater is determined. The mean values of ecological risk in soil and groundwater decreased with soil depth. Values of RQ(NCs) for groundwater were found at high ecological risk, for Ant, Chr, DahA, Acy, Pyr, BaA, Phe, Flo, Nap, Ace and Fluo, with values 28.57, 20.59, 300.00, 242.86, 185.71, 1700.0, 76.67, 53.33, 15.83, 100.00 and 57.14, respectively. ∑16PAH indicated high ecological risk for most PAHs, which decreased with soil depth. The value of RQ(NCs) for ΣPAHs in groundwater indicates high ecological risk (ΣPAHs ≥ 800 and RQ(MPCs) ≥ 1). This is the first study on the ecological risk of PAHs in soil and groundwater in industrial soils in Banja Luka and provides baseline information for further studies and additional investigations of this industrial complex.
多环芳烃(PAHs)是由人为活动形成的,即工业排放、石油、煤炭等化石燃料的不完全燃烧以及其他工业和家庭活动。这项研究的研究领域是波斯尼亚-黑塞哥维那斯普斯卡共和国巴尼亚卢卡市工业园区的四个代表性地点。本文的主要目的是确定土壤和地下水中多环芳烃污染的生态风险和评估可能的来源。本研究结果反映了煤燃烧(热源源)、岩源和生物质源的影响,可为该地区多环芳烃的修复提供基础数据。测定了土壤(30、100、200、300和400 cm深度)和地下水的生态风险。土壤和地下水生态风险均值随土层深度的增加而减小。地下水RQ(NCs)为高生态风险值,Ant、Chr、DahA、Acy、Pyr、BaA、Phe、Flo、Nap、Ace和Fluo分别为28.57、20.59、300.00、242.86、185.71、1700.0、76.67、53.33、15.83、100.00和57.14。∑16PAH表明大多数多环芳烃具有较高的生态风险,随土壤深度的增加而降低。地下水中ΣPAHs的RQ(NCs)值为高生态风险值(ΣPAHs≥800,RQ(MPCs)≥1)。本研究首次对巴贾卢卡工业园区土壤和地下水中多环芳烃的生态风险进行了研究,为该工业园区的进一步研究和调查提供了基线信息。

Abstract This review illustrates the state of air, water and soil pollution with heavy metals resulting from mining activities in the cross-border area of Romania and the Republic of Serbia. It also emphasizes the possible human health effects that certain heavy metals can cause. The heavy metals that were identified as polluting the air, water, and/or soil in the area of interest are: As, Cd, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, and Zn. Acute or chronic exposure to these heavy metals may cause numerous human health effects as they affect numerous organs and tissues (gastrointestinal tract, liver, lungs, kidneys, bladder, central nervous system, reproductive system, etc.). The review shows that the pollution produced by both abandoned and active mines cannot be neglected and underlines the necessity of changes in the current mining practices so that mining operations will assure better protection for the environment and human health.

Abstract Organic waste from production processes is unutilised potential for the production of energy from renewable sources. The submitted paper studies the conditions of anaerobic degradation of selected waste from food industry (diary and distillery) when biogas is produced. Both types of organic waste have low pH values. Ash form municipal incineration as a material for the treatment of pH of waste was used. Except for the pH increase during anaerobic degradation, ash also serves as a source of macroelements for inoculum microorganisms. Kinetics of anaerobic biological digestion of organic material based on the change of pressure and biogas production depending on the ash addition (change of pH) of input samples was observed. Beside these tests, degradability of the waste was assessed by limiting biologically degradable ratio, BR and specific speed of degradability, q. pH values were adjusted with different amounts of ash (0.5; 1.8; 2.7 g/g of dry matter of organic material). Results of the research confirmed that the addition of optimum amount of ash has a positive effect on anaerobic degradation of organic materials.
生产过程中产生的有机废物是可再生能源生产中未利用的潜力。本文研究了食品工业(乳制品和酿酒厂)中选定的废物在产生沼气时的厌氧降解条件。这两种有机废物的pH值都很低。利用城市焚烧产生的灰作为处理垃圾pH值的材料。除了在厌氧降解过程中pH值升高外,灰渣还可以作为接种微生物的常量元素来源。观察了压力变化对有机物厌氧生物消化动力学的影响,以及输入样品灰分添加量(pH值变化)对沼气产量的影响。除上述试验外,还通过限制生物降解比、BR和降解比速度、q来评估废物的可降解性,并根据不同的灰分量(0.5;1.8;2.7 g/g有机质干物质)。研究结果证实,最佳灰分投加量对有机物的厌氧降解具有积极作用。

Abstract Soil as an ecosystem is actively involved into climate formation process. Therefore, it is important to assess such soil quality indicators as total organic carbon (TOC) and CO2 emissions. Soil organic matter is considered to be its indicator of quality, which is one of the most important components of biosphere consistency and stability. Soil respiration shows carbon emission from soil into the atmosphere. This is a great indicator, illustrating soil biological activity. Impact of soil temperature, air humidity, time of day was evaluated on CO2 emission from the soil. The highest CO2 emission is observed in afternoon hours, up to 0.201 g CO2∙m–2·h–1.

Abstract Removal of textile dyes from wastewater have recently attracted much attention, due to the toxicity, difficult visibility, and thereby the negative consequences on the aqueous environment. Therefore, there have been diverse promising new techniques such as adsorption for dyes removal from industrial wastewater. Compared to the highly cost treatment techniques, removal of dyes using the adsorption process is relatively simple and requires less cost. Synthetic zeolite was used in this research as a high capacity nano-adsorbent for the removal of reactive dyes from coloured wastewater. The impact of main parameters: dose of adsorbent (0.0025 to 0.02 g), pollutant concentration (25 to 200 mg/L), contact time (10 to 120 minutes), degree of agitation (25 and 300 rpm), and solution pH (2 to 8) on adsorption performance of the synthesised zeolite was investigated. The optimum values of these parameters to remove dyes efficiently at 90 % removal were 0.02 g, 200 mg/L, 80 min, 300 rpm, and 6-7 respectively. Also, two models were evaluated, the Langmuir and Freundlich isotherms. Langmuir isotherm was more efficient for representing the data than the Freundlich. The results of the Langmuir isotherm gave KL = 0.08 L/mg, qm = 6.02 mg/g, and R2 = 0.98, which fitted to the adsorption data of zeolite. Reactive dye adsorption by synthetic zeolite is a vital tool in identifying the fate of dye removal from industrial wastewater treatment plants.
摘要纺织废水中染料的去除因其毒性大、不易被发现以及对水环境的不良影响而受到广泛关注。因此,出现了各种有前景的新技术,如吸附法去除工业废水中的染料。与高成本的处理技术相比,采用吸附法去除染料相对简单,成本较低。采用合成沸石作为高容量纳米吸附剂,对有色废水中的活性染料进行了脱除。考察了吸附剂用量(0.0025 ~ 0.02 g)、污染物浓度(25 ~ 200 mg/L)、接触时间(10 ~ 120 min)、搅拌程度(25 ~ 300 rpm)、溶液pH(2 ~ 8)对合成沸石吸附性能的影响。这些参数的最佳去除率分别为0.02 g、200 mg/L、80 min、300 rpm和6-7。同时,对Langmuir等温线和Freundlich等温线两种模型进行了评价。Langmuir等温线比Freundlich等温线更能有效地表示数据。Langmuir等温线的KL = 0.08 L/mg, qm = 6.02 mg/g, R2 = 0.98,与沸石吸附数据吻合。合成沸石对活性染料的吸附是确定工业废水处理厂染料去除率的重要工具。

Abstract Lipase activity is a perfect indicator for the monitoring of processes of bioremediation of degraded soils. Lipase is also used in the processes of oil hydrolysis in wastewater treatment. To be able to predict and model processes with used lipase in environmental operations, knowledge of the kinetic parameters of the process are required. The paper presents the determined values of activation energies and optimum temperatures for porcine pancreas lipase. The parameters were estimated based on the literature of the activity curves vs. temperature for hydrolysis of olive oil by lipase. It was noticed that concentration of gum arabic added as an emulsifier during lipase activity measurements influences on the obtained values of determined parameters. A mathematical model describing the effect of temperature on porcine pancreas lipase activity was used. Based on the comparison analysis, the optimum temperature Topt were obtained in the range from 313.30 ±0.56 to 319.62 ±0.96 K, activation energies Ea were from 51 ±10 to 82.6 ±9.9 kJ/mol, and values of deactivation energies Ed were in the range from 122.7 ±4.0 to 150.9 ±5.8 kJ/mol.
脂肪酶活性是监测退化土壤生物修复过程的理想指标。脂肪酶还可用于废水处理中油脂的水解过程。为了能够预测和模拟环境操作中使用过的脂肪酶的过程,需要了解该过程的动力学参数。本文介绍了猪胰脂肪酶的活化能测定值和最佳温度。这些参数是根据脂肪酶水解橄榄油的活性随温度变化曲线的文献来估计的。注意到,在脂肪酶活性测定中,作为乳化剂加入的阿拉伯胶的浓度对测定参数的所得值有影响。建立了温度对猪胰腺脂肪酶活性影响的数学模型。通过对比分析,得到了最佳温度Topt为313.30±0.56 ~ 319.62±0.96 K,活化能Ea为51±10 ~ 82.6±9.9 kJ/mol,失活能Ed为122.7±4.0 ~ 150.9±5.8 kJ/mol。

Abstract The present study aimed to analyse changes in the land cover of Vilnius city and its surrounding areas and propose a scenario for their future changes using an Artificial Neural Network. The land cover dynamics modelling was based on a multilayer perceptron neural network. Landscape metrics at a class and landscape level were evaluated to determine the amount of changes in the land uses. As the results showed, the Built-up area class increased, while the forest (Semi forest and Dense forest) classes decreased during the period from 1999 to 2019. The predicted scenario showed a considerable increase of about 60 % in the Built-up area until 2039. The vegetation plant areas consist about 47 % of all the area in 2019, but it will be 36 % in 2039, if this trend (urban expansion) continues in the further. The findings further indicated the major urban expansion in the vegetation areas. However, Built-up area would expand over Semi forest land and Dense forest land, with a large part of them changed into built- up areas.
摘要:本研究旨在分析维尔纽斯市及其周边地区的土地覆盖变化,并利用人工神经网络提出其未来变化的情景。土地覆盖动态建模基于多层感知器神经网络。评估了类和景观水平的景观指标,以确定土地利用的变化量。结果表明:1999 - 2019年,建成区面积增加,森林(半森林和茂密森林)减少;预测的情景显示,到2039年,建成区面积将大幅增加约60%。2019年,植被植物面积约占总面积的47%,如果这一趋势(城市扩张)继续下去,到2039年将达到36%。研究结果进一步表明,城市扩张主要发生在植被区。而建成区将向半林地和茂密林地扩展,其中很大一部分将变成建成区。

Abstract The use of antibiotics for breeding and for humans increased considerably in recent years, as a dietary supplement to enhance animal growth. This frequent use leads to the detection of residues in water and wastewater. Thus, the emergence of new strains of bacteria resistant to these antibiotics and, can lead to incurable diseases of livestock, and can lead to a possible transmission of these strains to humans. The purpose of this work is to develop new materials based on treated Maghnia clay, activated carbon, cement, and PVA polymer, named geomaterials. These materials were intended for the containment of hazardous wastes in landfills. The removal of tetracycline from aqueous solution was tested by adsorption onto synthesised geomaterials and their mineral constituents. Adsorption kinetics revealed that tetracycline was rapidly retained by GM and ATMa. This was confirmed by the relatively short equilibrium time of 30 min. The pseudo-second-order and intraparticle models well fitted the adsorption kinetic of the TC-adsorbent studied systems. It was noticed that the adsorption kinetic passes through several mechanisms, was demonstrated by the multi-linearity on the plot of qt against the square root of t. The adsorption capacity (Qa) of TC onto GM is pH-dependent. Indeed, Qa reaches a maximum value (Qa = 12.58 mg ∙ g–1 at a very acidic pH of 2, then the adsorbed amount decreases to reach a minimum value at pH of 8, and for basic pHsQa increases up to 10 mg ∙ g–1.
摘要近年来,抗生素作为一种促进动物生长的膳食补充剂,用于育种和人类的使用大幅增加。这种频繁的使用导致在水和废水中检测残留物。因此,对这些抗生素产生耐药性的新菌株的出现可能导致牲畜无法治愈的疾病,并可能导致这些菌株传播给人类。这项工作的目的是开发基于处理过的磁铁矿粘土、活性炭、水泥和聚乙烯醇聚合物的新材料,称为岩土材料。这些材料的目的是在垃圾填埋场遏制危险废物。研究了合成的土工材料及其矿物组分对四环素的吸附效果。吸附动力学表明,四环素被GM和ATMa快速保留。相对较短的平衡时间(30 min)证实了这一点。伪二级和颗粒内模型很好地拟合了所研究的tc -吸附剂体系的吸附动力学。通过qt与t的平方根的线性关系可以看出,TC在GM上的吸附量Qa与ph值有关。事实上,当pH为2时,Qa达到最大值(Qa = 12.58 mg∙g-1),然后在pH为8时吸附量减少至最小值,对于碱性pHsQa增加至10 mg∙g-1。

Abstract The aim of the studies was to investigate the effect of camel grass, lavender, patchouli, peppermint and tea tree essential oils, and their mixtures on the in vitro growth of pathogenic fungi Cladobotryum dendroides and Mycogone perniciosa, occurring in the cultivation of button mushroom (Agaricus bisporus). The mycelial growth of the tested pathogens was evaluated on PDA medium. Essential oils were added in three doses: 0.25; 0.5 and 1 mg·cm–3 of PDA medium. Camel grass and peppermint essential oils applied at the highest dose inhibited completely the in vitro growth of C. dendroides mycelium. Lavender oil used at the amount of 1 mg·cm–3 reduced the growth of the pathogen by 90 %. In the case of M. perniciosa the complete inhibition of the pathogen’s growth was observed after the addition of camel grass oil to PDA medium, irrespective of a dose, and lavender oil at the doses of 0.5 and 1 mg·cm–3. The efficacy of the tested mixtures against M. perniciosa was high. Generally, all mixtures of essential oils, irrespective of a dose, completely controlled the growth of the pathogen. The complete inhibition of the growth of C. dendroides was observed only on the medium with the addition of the mixture of camel grass and peppermint oils at the highest dose. The conducted research showed that natural essential oils due to their antifungal properties could be useful in the Integrated Disease Management for the protection of button mushroom against diseases. They could be an effective alternative to synthetic chemical fungicides.
摘要本试验旨在研究骆驼草、薰衣草、广藿香、薄荷和茶树精油及其混合物对双孢蘑菇(Agaricus bisporus)培养过程中病原菌枝状分枝杆菌(Cladobotryum dendroides)和灰霉病菌(mycogo perniciosa)体外生长的影响。在PDA培养基上观察病原菌菌丝生长情况。精油按三种剂量添加:0.25;0.5、1mg·cm-3 PDA培养基。最高剂量的骆驼草和薄荷精油完全抑制了树突线虫菌丝体的体外生长。薰衣草精油用量为1 mg·cm-3时,病原菌的生长速度降低90%。在PDA培养基中添加骆驼草油(不论剂量)和薰衣草油(0.5和1 mg·cm-3)均能完全抑制perniciosa病原菌的生长。所试混合药剂对黑僵菌的防治效果较高。一般来说,所有精油的混合物,无论剂量多少,都能完全控制病原体的生长。只有在添加了最高剂量的骆驼草和薄荷油的混合物的培养基上,才能观察到对石斛生长的完全抑制。研究表明,天然精油具有抗真菌特性,可用于菌类病害综合防治。它们可能是合成化学杀菌剂的有效替代品。
