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.","PeriodicalId":506819,"journal":{"name":"Revista Internacional de Contaminación Ambiental","volume":"67 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140238199","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}

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.","PeriodicalId":506819,"journal":{"name":"Revista Internacional de Contaminación Ambiental","volume":"17 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140254489","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}

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.","PeriodicalId":506819,"journal":{"name":"Revista Internacional de Contaminación Ambiental","volume":"13 S1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140425259","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 analyzed properties of the concrete included consistency, density, compressive strength, and flexural strength.

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.","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}
