En México existe una tendencia por reformar las legislaciones estatales de gestión de residuos con la intención de frenar la dispersión de plásticos de un sólo uso (P1U) y fomentar la reducción de residuos mediante acciones de corresponsabilidad. Actualmente, 29 de los 32 estados mexicanos establecen en sus leyes la participación de sectores de la sociedad para motivar una gobernanza de los plásticos. Sin embargo, aún no existe un estudio nacional que brinde información sobre la forma en la que se está distribuyendo la responsabilidad dentro de las legislaciones. Por ello, el objetivo de este estudio fue evaluar a través de un análisis de redes la diversidad de actores y su inclusión como sectores dentro de la legislación que hasta ahora regula los P1U en México. Los hallazgos de la investigación indican que para frenar la dispersión de P1U el 90 % de las entidades federativas, de acuerdo con su legislación, se apoyan en el sector económico de la distribución y comercialización. Además, a nivel nacional, se observó una subrepresentación de la responsabilidad de los sectores productivo y académico. En este sentido el presente estudio ofrece una propuesta metodológica para visualizar de forma resumida y esquemática la diversidad de actores y sectores en el complejo panorama de la corresponsabilidad para la reducción de P1U. La herramienta de análisis de redes podría ser aprovechada para facilitar la tarea de los tomadores de decisión o para investigaciones que consideren la revisión legislativa cuantitativa.
在墨西哥,改革各州废物管理立法是大势所趋,目的是遏制一次性塑料(P1U)的扩散,并鼓励通过共同责任行动减少废物。目前,墨西哥 32 个州中有 29 个州在法律中规定社会各界参与鼓励塑料治理。然而,目前还没有一项全国性研究能够提供有关如何在立法中分配责任的信息。因此,本研究的目的是通过网络分析,评估行动者的多样性及其作为部门被纳入墨西哥迄今为止规范 P1U 的立法中的情况。研究结果表明,为了遏制 P1U 的扩散,90% 的州根据其立法,依靠分销和商业化经济部门。此外,在全国范围内,生产部门和学术部门的责任代表性不足。从这个意义上说,本研究提供了一种方法建议,以概括和图示的方式直观地展示了在减少 P1U 的复杂共同责任全景中参与者和部门的多样性。网络分析工具可用于促进决策者的任务或考虑定量立法审查的研究。

Mercury (Hg) is the most harmful heavy metal for living beings due to its high toxicity, persistence, and bioaugmentation in the food web. Lantana camara has been considered promising for the phytoremediation of different metals, but its response to Hg has not been characterized. The objective of this study was to evaluate the effectiveness of L. camara to bioaccumulate, translocate, and volatilize Hg in artificially contaminated soils (1.0 and 8.0 mg/kg Hg). After two months of treatment, the dry weight was measured and the Hg present in stems, roots, leaves, and atmosphere was quantified using atomic absorption spectroscopy. The volatilized Hg was captured in hermetic chambers with continuous airflow, connected to a trap solution (5 % KMnO4 dissolved in H2SO4). The translocation factor was < 1, and the bioaccumulation factor was > 1 in both treatments. The Hgº values volatilized in high mercury indicate that approximately 7.1 µg/g plant/day can be released into the atmosphere. Our results indicate that L. camara accumulates Hg mainly in the root, showing potential for phytostabilization, but the observed volatilization rates point towards a more restricted use of this species in phytoremediation strategies.
汞(Hg)是对生物最有害的重金属,因为它具有高毒性、持久性和在食物网中的生物增殖性。山茶属植物被认为在不同金属的植物修复方面很有前景,但其对汞的反应尚未定性。本研究的目的是评估香蒲在人工污染土壤(1.0 和 8.0 毫克/千克汞)中生物累积、转移和挥发汞的效果。处理两个月后,测量茎、根、叶和大气中的干重,并使用原子吸收光谱对其中的汞含量进行定量。挥发的汞被收集到连续通气的密闭容器中,容器与捕集溶液(溶于 H2SO4 的 5 % KMnO4)相连。在这两种处理中,迁移系数均小于 1,生物累积系数大于 1。高汞挥发的 Hgº 值表明,大约 7.1 微克/克植物/天可释放到大气中。我们的研究结果表明,L. camara 主要在根部积累汞,具有植物稳定的潜力,但观察到的挥发率表明,该物种在植物修复战略中的应用受到限制。

El uso de sustancias químicas en los centros de trabajo conlleva un riesgo inherente que pocas veces se reconoce con facilidad, es por ello que en el presente trabajo se pretende ofrecer una guía para el entendimiento del Sistema Globalmente Armonizado (SGA) y su aplicación en el reconocimiento y clasificación de riesgos químicos en los centros de trabajo. Con fines prácticos, la guía se divide en cuatro etapas. La etapa I, consiste en la descripción e interpretación de los elementos del SGA. En la etapa II se realiza la identificación de los peligros que representan las sustancias químicas, en la siguiente etapa se hace el registro de la descripción de peligro. Por último, en la cuarta y última etapa se clasifican las sustancias con base en la compatibilidad química y los riesgos que representan. Finalmente, se abordan algunas consideraciones importantes para el manejo y almacenamiento de las sustancias químicas peligrosas en los centros de trabajo.
在工作场所使用化学品会带来固有的风险,而这种风险很少能被轻易识别,因此本文旨在提供一份指南,帮助人们了解《全球统一制度》(GHS)及其在工作场所化学品危害识别和分类中的应用。出于实用目的,本指南分为四个阶段。第一阶段包括对《全球统一制度》要素的描述和解释。第二阶段是识别化学物质所代表的危害,下一阶段是记录危害描述。最后,在第四阶段,也是最后一个阶段,根据化学兼容性和所代表的风险对物质进行分类。最后,介绍了在工作场所处理和储存危险化学品的一些重要注意事项。

Los pasivos ambientales mineros (PAM) son residuos con alta carga de metales que tienen el potencial de contaminar el suelo circundante, afectar negativamente la calidad del agua y aire, degradar los ecosistemas y provocar efectos tóxicos en la salud humana. Este estudio utilizó el tratamiento electroquímico como técnica de remediación para descontaminar un suelo afectado por PAM. A través de un diseño factorial mixto se investigó los efectos de las soluciones de mejora, ácido acético y ácido nítrico, y tres distancias del suelo respecto al ánodo, sobre la concentración residual y distribución espacial unidimensional de Pb, Cd y Zn. Los ensayos se realizaron por triplicado, en celdas de acrílico, durante cinco días, sometidos a 30 V de potencia y con ácido nítrico como fluido catódico. Los resultados demostraron que el ácido nítrico reduce 4.0, 11.5 y 11.3 veces el contenido de Pb, Cd y Zn en comparación con el ácido acético, es decir, que los mayores porcentajes de remoción del Pb, Zn y Cd fueron 40, 34 y 23 % respectivamente, al emplear ácido nítrico. Asimismo, la distribución espacial unidimensional de los metales en el suelo después del tratamiento, no fue un gradiente de concentración creciente desde la región anódica hacia la región catódica, sino una tendencia homogénea. Por tanto, emplear ácido nítrico como fluido de mejora confirmó la viabilidad del tratamiento electroquímico, aunque se debería potenciar en otras condiciones experimentales para alcanzar mayores tasas de remediación.
采矿环境污染(MAPs)是一种含有金属的废物,有可能污染周围的土壤,对水质和空气质量造成不利影响,导致生态系统退化,并对人类健康产生毒害作用。本研究采用电化学处理作为一种修复技术来净化受 MAP 影响的土壤。采用混合因子设计,研究了增强溶液、醋酸和硝酸以及土壤与阳极的三个距离对铅、镉和锌的残留浓度和一维空间分布的影响。试验一式三份,在丙烯酸电池中进行,为期五天,电压为 30 V,硝酸为阴极液。结果表明,与醋酸相比,硝酸对铅、镉和锌含量的去除率分别为 4.0、11.5 和 11.3 倍,即使用硝酸时,对铅、锌和镉的去除率最高,分别为 40%、34% 和 23%。此外,处理后土壤中金属的一维空间分布并不是从阳极到阴极区域的浓度梯度增加,而是呈均匀趋势。因此,使用硝酸作为改良液证实了电化学处理方法的可行性,不过要想获得更高的修复率,还需要在其他实验条件下进行改进。

Improper management of plastic bottle waste is harming the environment. Recycling this waste for inclusion in the concrete matrix is a viable alternative for its final disposal. The objective of this study was to evaluate the mechanical behavior of conventional concrete with the addition of polyethylene terephthalate (PET) fibers, designed according to the procedures established by the American Concrete Institute for a strength of 20 MPa. The analyzed properties of the concrete included consistency, density, compressive strength, and flexural strength. Sixty cylindrical and 60 prismatic specimens with PET fiber additions of 0%, 2%, 4%, 6%, and 8% by weight of cement were prepared for testing at 7, 14, and 28 days of curing. The results indicate that maximum compressive and flexural strengths of 22.79 MPa and 3.19 MPa are achieved at 28 days by adding 2% and 6% PET fibers. Therefore, its application is recommended up to a proportion of 4%, where the corresponding dosage is 15.78 kilograms of PET fibers per cubic meter of concrete with a workable consistency.
塑料瓶废物的不当管理正在危害环境。回收这些废料并将其加入混凝土基质中,是替代其最终处置的一种可行方法。本研究的目的是评估添加了聚对苯二甲酸乙二酯(PET)纤维的传统混凝土的机械性能,该混凝土是根据美国混凝土协会制定的程序设计的,强度为 20 兆帕。分析的混凝土特性包括稠度、密度、抗压强度和抗折强度。制备了 60 个圆柱形和 60 个棱柱形试样,其中 PET 纤维的添加量分别为水泥重量的 0%、2%、4%、6% 和 8%,分别在养护 7 天、14 天和 28 天时进行测试。结果表明,添加 2% 和 6% PET 纤维的水泥在 28 天时的最大抗压和抗折强度分别为 22.79 兆帕和 3.19 兆帕。因此,建议将 PET 纤维的使用比例提高到 4%,即每立方米可施工稠度混凝土的 PET 纤维用量为 15.78 千克。

Environmental pollution is a major problem worldwide. One of the major health issues is the consumption of potentially toxic elements through fish intake, particularly in urban areas. Therefore, it is necessary to assess the human health risks of fish consumers. This study aims to determine concentrations of As, Cd, Cr, Cu, Hg, Pb, and Zn in the liver and muscle of freshwater carp (Cyprinus carpio) caught in El Tunal River, Durango, Mexico. Carps were collected in dry (n = 7) and rainy (n = 10) seasons. The highest concentrations of all elements were found in the liver, where As and Zn (4.83 and 6.51 µg/g w/w, respectively) were predominant. Meanwhile, As, Cr, and Zn (1.00, 1.12, and 1.09 µg/g w/w, respectively) were predominant in muscle. The concentrations of As, Cd, Cr, Pb, and Zn had significant differences between seasons (p < 0.05), showing that during the rainy season the concentration of elements in the river, and hence in fish tissues, was reduced. Elements in edible tissue were below the levels allowed in Mexico and by international agencies. The mean and total target hazard quotients were below 1, indicating a minor risk to human health. Based on this study, fish consumption does not represent a risk to human health; however, it is necessary to continue monitoring pollutants since their accumulation can increase over time.
环境污染是全世界的一个主要问题。其中一个主要的健康问题是通过摄入鱼类,特别是在城市地区摄入潜在的有毒元素。因此,有必要对鱼类消费者的人体健康风险进行评估。本研究旨在确定在墨西哥杜兰戈州埃尔图纳尔河捕获的淡水鲤鱼(Cyprinus carpio)肝脏和肌肉中的砷、镉、铬、铜、汞、铅和锌浓度。鲤鱼是在旱季(7 条)和雨季(10 条)采集的。所有元素的最高浓度都出现在肝脏中,其中主要是砷和锌(分别为 4.83 和 6.51 µg/g w/w)。同时,肌肉中主要含有砷、铬和锌(分别为 1.00、1.12 和 1.09 微克/克(湿重))。砷、镉、铬、铅和锌的浓度在不同季节有显著差异(p < 0.05),表明在雨季,河流中的元素浓度降低,因此鱼类组织中的元素浓度也降低。可食用组织中的元素含量低于墨西哥和国际机构允许的水平。平均危险商数和总目标危险商数均低于 1,表明对人类健康的风险较小。根据这项研究,食用鱼类不会对人类健康造成风险;但是,有必要继续监测污染物,因为污染物的累积会随着时间的推移而增加。

Based on this study, fish consumption does not represent a risk to human health; however, it is necessary to continue monitoring pollutants since their accumulation can increase over time.","PeriodicalId":506819,"journal":{"name":"Revista Internacional de Contaminación Ambiental","volume":"17 27","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140430239","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}

Landscape protection and tourism development are a pair of contradictions in the revitalization of traditional villages. It is an important topic to study the coordination between them. This research reveals the interactive mechanism between the protection of traditional rural features and the development of tourism, based on which the evaluation model and index system of the coordination degree of the composite system are constructed. The result is illustrated by the example of the first three plots of traditional Chinese villages in the Gansu Longzhong area from 2013 to 2018. The evolution trend of the traditional village landscape protection subsystem, the development of the tourism subsystem, and the composite system’s coordination degree were analyzed. The results show that the coordination of traditional village landscape protection and tourism development composite system at the same base period gradually increases. Nevertheless, the coordination between adjacent base periods is at a low level. The increase in the synergy between the landscape protection subsystem and the tourism development subsystem tends to be the same, and the two subsystems are in a positive development that promotes each other. Based on the above conclusions, this research puts forward the coordination strategies and suggestions for the protection of traditional villages and tourism development.
景观保护与旅游开发是传统村落振兴过程中的一对矛盾。研究二者之间的协调关系是一个重要课题。本研究揭示了传统乡村风貌保护与旅游开发之间的互动机制,在此基础上构建了复合系统协调度的评价模型和指标体系。结果以甘肃陇中地区2013-2018年中国传统村落前三个地块为例进行说明。分析了传统村落景观保护子系统、旅游子系统的发展演变趋势以及复合系统的协调度。结果表明,传统村落景观保护与旅游发展复合系统在同一基期的协调度逐渐提高。然而,相邻基期之间的协调度较低。景观保护子系统与旅游开发子系统之间的协同性增加趋于一致,两个子系统处于相互促进的良性发展状态。基于以上结论,本研究提出了传统村落保护与旅游开发的协调策略与建议。

The explainable boosting machine (EBM) model measures China’s provincial eco-efficiency, and the Tobit regression model reveals internal driving factors to provide consultation for promoting China’s green development based on the panel data of 30 provinces from 2000 to 2018. The findings of this article are as follows: provincial-level regional ecological efficiency is low, growth is slow, regional differentiation is significant, and development still has a trend of incoordination and multi-polarization. From the perspective of global autocorrelation, the Moran index is significantly positive, and the province eco-efficiency of the first grade presents a positive spatial correlation and has the characteristics of spatial agglomeration. The regression analysis results show that the economic level, the FDI, the level of technological innovation, and the level of human capital are the main influencing factors of eco-efficiency, and there are spatial differences. Relevant suggestions are based on the status and influencing factors of the unbalanced development heterogeneity of provincial eco-efficiency in China.
可解释助推机(EBM)模型测度中国省级生态效率,基于2000-2018年30个省份的面板数据,采用Tobit回归模型揭示内部驱动因素,为推动中国绿色发展提供咨询。本文的研究结论如下:省级区域生态效率偏低,增长缓慢,区域分化显著,发展仍有不协调和多极化趋势。从全局自相关角度看,莫兰指数显著为正,省域生态效率一级指标呈现正空间相关性,具有空间集聚特征。回归分析结果表明,经济水平、FDI、技术创新水平、人力资本水平是生态效率的主要影响因素,且存在空间差异。基于中国省域生态效率非均衡发展异质性的现状和影响因素,提出了相关建议。
