Even though ammonia is a natural component of aquatic environments, elevated concentrations indicate pollution and environmental degradation. Consequently, efficient analytical methods for monitoring ammonia levels are crucial for preserving water quality. Voltammetry offers a sustainable approach for NH3 quantification, combining good analytical performance with low sample and reagent consumption, minimizing waste generation. However, despite these advantages, the voltammetric determination of ammonia remains relatively unexplored. Therefore, this study investigated the electrochemical behavior of NH3 in alkaline solutions using a non-modified Pt electrode and evaluated the performance of differential pulse voltammetry (DPV) and square wave voltammetry (SWV) for NH3 determination. DPV provided superior performance, with limits of detection and quantification of 0.79 µmol L-1 (0.011 ppmN) and 2.6 µmol L-1 (0.036 ppmN), respectively, which comply with the maximum allowable ammonia concentration in natural waters according to Brazilian and European regulations. The voltammetric method successfully quantified ammonia in tap and river water samples, providing results concordant with the established Berthelot spectrophotometric method, at a 95% confidence level. Additionally, it is simple and fully accessible to non-electrochemist since no sophisticated procedures for electrode modification are needed. Finally, the high analytical performance of the proposed method makes it valuable for pollution monitoring in aquatic environments. environments degradation Consequently quality NH consumption generation However advantages unexplored Therefore nonmodified non modified (DPV SWV (SWV 079 0 79 0.7 L1 L 1 L- 0.011 0011 011 (0.01 ppmN 26 2 6 2. 0.036 0036 036 (0.03 ppmN, , respectively regulations samples 95 level Additionally nonelectrochemist electrochemist needed Finally 07 7 0. 0.01 001 01 (0.0 0.03 003 03 9 0.0 00 (0.

Caffeine (CAF) and nicotine (NIC) are emerging contaminants and are among the most consumed substances in the world, making it crucial to monitor these contaminants. In this work, an alternative electrolyte, 2-hydroxyethylammonium acetate (2HEAA) was used for the development of an electroanalytical method for determination and quantification of CAF and NIC, simultaneously, using differential pulse voltammetry (DPV). The system with the 2HEAA electrolyte was characterized by cyclic voltammetry and electrochemical impedance spectroscopy, and the DPV parameters were optimized for the best conditions. The method was validated from a calibration curve obtained which showed limit of detection (LOD) of 0.82 and 6.26 μmol L 1 and limit of quantification (LOQ) of 2.73 and 20.8 μmol L-1 for CAF and NIC, respectively. In the precision analyses, values lower than 10% of relative standard deviation were obtained. In the presence of concomitant inorganic and organic species, the system proved to be selective in the determination of analytes. The method was used to determine the analytes in fortified samples (river water, synthetic urine and commercial milk), obtaining recoveries between 87.25 and 111.40%. The 2HEAA demonstrated high efficiency as an alternative electrolyte with good signal-to-noise ratio, increased analytical sensitivity of the method, in addition to presenting low cost and fast electrolyte preparation.

Abstract Nowadays, organizations have the responsibility to commit themselves to actions that favor environmental conservation. The present study sought to explore an accompaniment for the management of the environmental component in the activities developed by an organization located in Armenia, Quindío-Colombia. Inter-institutional meetings were held in which a recognition, dialogue and workshop were conducted with the collaborators. A previously validated checklist was used. Subsequently, a descriptive analysis was made of the results obtained. It was found that 40 % of the components lacked actions for environmental conservation. Thus, the accompaniment showed that the collaborators committed themselves to use solid waste, save water and energy. The monitoring resulted in three strategic actions for the water, soil and energy components. The organization showed great interest in the process and an intersectoral link was established. The study proposes a baseline for the management of the environmental component of the study area; it resulted in an accompaniment and representative participation with significant progress towards the conservation of the environment within the organization.

ABSTRACT Mental health in the Unified Health System has experienced a dispute between disease-centered care and socio-environmental determinants. The study of state co-financing of the Psychosocial Care Network in Rio de Janeiro (2019 to 2022) aimed to explain how theoretical-conceptual elements about mental health were relevant in interfederative financing decisions in this period. A review of federal and state regulations of the Intermanagement Committees (Bipartite and Tripartite), technical notes and Fala.BR site was carried out. The documents demonstrated the interfederative rupture in relation to territorial and community-based mental health care. During this period, while the Ministry of Health directed its agenda towards outpatient and specialized care, Rio de Janeiro increased the state’s financial resource for mental health by R$ 175 million to strengthen Psychosocial Care Centers and Therapeutic Residential Services qualified or eligible for qualification. The deinstitutionalization of asylum survivors and the expansion of the care network for crisis situations are results found in Rio de Janeiro. The conclusion of the study suggests the construction of an interfederative monitoring methodology for public mental health financing so that the delivery of care is increasingly closer to the needs of citizens and territorial vulnerabilities. diseasecentered disease centered socioenvironmental socio environmental determinants cofinancing co 2019 (201 2022 theoreticalconceptual theoretical conceptual period Bipartite Tripartite, Tripartite , Tripartite) FalaBR Fala BR out communitybased community based states s R 17 qualification vulnerabilities 201 (20 202 1 20 (2 2 (

Abstract The research presents a compilation of the strategies for the handling and management of mercury (Hg) carried out by Japan as a promoter and manager of the Minamata Convention. This agreement was established to reduce anthropogenic mercury emissions and prevent pollution worldwide. Article 14 of the agreement focuses on cooperation between the governments involved and provides technical assistance. That is why the activities were developed in the training course “Capacity building for the ratification and implementation of the Minamata Convention on Mercury” carried out in Japan, in which representatives from Ecuador, China, Sudan, Brazil, and Armenia. Ecuador is one of the countries that ratified this agreement in 2013, which is why it is necessary to understand the efforts developed by other countries, with a practical perspective, to know their feasibility and implementation in the long term in the national territory. This study describes the activities implemented in Japan, such as processing contaminated waste in the company Nomura Kohsan Co., Ltd. (Hokkaido), to know high-tech centers such as the National Institute for Minamata Disease (NIMD) and the Ministry of the Environment (MEGJ), and a tour of the environmental restoration project in Minamata Bay. The results demonstrate that the actions and policies adopted in Japan have considerably reduced Hg emissions, maintaining them at stable levels, which ratifies compliance with the different articles outlined in the Minamata Convention. Although efforts have been made in Ecuador to combat illegal mining where Hg and assist in mining districts, it is still among the most polluting countries in the region. Private and government entities must put effort into action plans to mitigate pollution and carry out periodic monitoring of emissions of this metal.

Resumen La investigación presenta una recopilación de las estrategias en el manejo y gestión del mercurio (Hg) que realiza Japón como promotor y gestor del Convenio de Minamata. Este acuerdo fue establecido para reducir las emisiones antropogénicas de mercurio y prevenir su polución a nivel mundial. El artículo 14 del convenio establece la cooperación entre los gobiernos involucrados y la prestación de asistencia técnica. Es por ello que las actividades se desarrollaron en el curso de capacitación “Capacity building for ratification and implementation of Minamata Convention on Mercury”, llevado a cabo en Japón, en el cual participaron representantes de Ecuador, China, Sudán, Brasil y Armenia. Ecuador es uno de los países que ratificó en el 2013 este convenio, por lo cual es necesario comprender los esfuerzos desarrollados por otros países, desde una perspectiva práctica, para poder conocer su factibilidad y ser implementadas a largo plazo en el territorio nacional. Se describen las actividades implementadas, en Japón, como la recolección y procesamiento de residuos contaminados en la empresa Nomura Kohsan Co., Ltd. (Hokkaido), visita a centros de alta tecnología como el Instituto Nacional para la Enfermedad de Minamata (NIMD) y el Ministerio del Ambiente (MEGJ), y recorrido por el proyecto de restauración ambiental en la bahía de Minamata. Los resultados demuestran que las acciones y políticas adoptadas en Japón han reducido considerablemente las emanaciones de Hg llegando a mantenerlas en niveles estables, lo que ratifica el cumplimiento de los distintos artículos expuestos en el Convenio de Minamata. A pesar de que en Ecuador se han hecho esfuerzos para mitigar el uso de Hg, aun así, se encuentra entre los principales países contaminantes de la región. Las entidades privadas y gubernamentales deben esforzarse en planes de acción para mitigar la contaminación y llevar a cabo monitoreos periódicos de las emisiones de este metal.

ABSTRACT Astructural, morphological and environmental description of tea mangrove individuals (genus Pelliciera) is presented. The specimens studied were found in eight sectors of Caño Salado which is a preservation zone in the Cispatá Bay Management Plan, using monitoring plots of 500 m2 (20 m x 25 m). The reported samples presented characters consistent with the recently redescribed species Pelliciera benthamii, found in forest relicts with a disperse spatial distribution. Reports of this species in the Cispatá bay are of great importance for the knowledge of the Colombian mangroves and to generate conservation and restoration initiatives that will have a positive impact on the populations of Pelliciera mangrove trees currently in state of threat.

Abstract (Introduction): In Latin America, the sensitive tropical biodiversity found outside of protected wilderness areas is under threat. In Costa Rica, the payment for environmental services (PSA) represents a mechanism to protect forests on private farms, but it lacks specific indicators on the state of biodiversity and forest conservation. (Objective): To analyze the use of acoustic monitoring for ecosystem assessment at 11 sites in the Osa Peninsula, nine on private farms, and two sites within Corcovado National Park. (Methods): Soundscapes were recorded from May 25 to June 1, 2021, using acoustic recorders. It was analyzed the behavior of six acoustic indices at each sampling site and applied an automated detection analysis of vocalizations of two representative bird species of the area. (Results): It was found that the most fragmented sites presented higher activity, energy, and acoustic diversity, possibly due to edge effects and ecotones present, as well as a high forest component in the surrounding matrix. Automated vocalization detection indicated that the species Hylopezus perspicillatus turned out to be more sensitive to differences in the landscape than Trogon bairdii. (Conclusions): The use of acoustic indices, although it associates features of the degree of conservation, was not a differentiating element of the quality of the ecosystem in the evaluated farms. The monitoring of species through the detection of their vocalizations was promising. A careful and rigorous sampling design, with more sampling points per site, is recommended to achieve accurate measurements and avoid bias in the analysis.

Resumen (Introducción): En Latinoamérica, la sensible biodiversidad tropical que se encuentra fuera de las áreas silvestres protegidas está bajo amenaza. En Costa Rica, el pago por servicios ambientales (PSA) representa un mecanismo para proteger bosques en fincas privadas, pero carece de indicadores específicos sobre el estado de la biodiversidad y de conservación de los bosques. (Objetivo): Analizar el uso del monitoreo acústico para la evaluación de ecosistemas en 11 sitios en la Península de Osa: 9 en fincas privadas y 2 sitios dentro del Parque Nacional Corcovado. (Metodología): Se grabaron paisajes sonoros del 25 de mayo al 01 de junio del 2021, utilizando grabadoras acústicas. Se estudia el comportamiento de 6 índices acústicos en cada sitio de muestreo y se aplicó un análisis de detección automatizada de vocalizaciones de 2 especies de aves representativas de la zona. (Resultados): Se encuentra que los sitios más fragmentados presentaron mayor actividad, energía y diversidad acústica, posiblemente por efectos de borde y ecotonos presentes, así como un alto componente de bosque en la matriz circundante. La detección automatizada de vocalizaciones indicó que la especie Hylopezus perspicillatus resultó ser más sensible a las diferencias en el paisaje que Trogon bairdii. (Conclusiones): El uso de índices acústicos, aunque asocia rasgos del grado de conservación del bosque, no resultó un elemento diferenciador de la calidad del ecosistema en las fincas evaluadas, pero el monitoreo de especies mediante la detección de sus vocalizaciones sí resultó promisorio. Es recomendable un diseño de muestreo metódico y riguroso, con más puntos de muestreo por sitio, para lograr mediciones precisas y evitar sesgos en el análisis.

Abstract (Introduction): In July 2023 was announced the end of planetary warming and the beginning of the era of the global boiling. A climatic anomaly that unprecedented, aggressiveness will hit the Central American region. (Methodology): Through technological surveillance tools and data analytics, this study shows a series of challenges and opportunities to meet this threat and move towards resilient regional performance. (Results): All countries have signed agreements and declaratory public policies for the climate resilience, however historical failures persist as well environmental passives to reduce greenhouse gas emissions and the strong dependence for the use of fossil energy. In contrast, Central America enjoys a matrix of opportunities to increase the climatic ambition, also a diverse mix of renewable energy sources, environmental pay mechanisms and actions to impulse circular economy and the bioeconomy (Conclusions): The regional agenda fail in connect to a climate shielding to respond the rigors of the boiling era. Regarding those balances, and the scientific evidence, a road map, with climate smart and socially inclusive actions, is proposed. (Recommendations): For the monitoring, research, and education programs on the boiling era, a regional observatory, on climate resilience (OR2C), is recommended.

Resumen (Introducción): En julio del 2023 se anunció el fin del calentamiento planetario y el inicio de la era de la ebullición global. Una anomalía climática cuya agresividad, sin precedentes, azotará la región centroamericana. (Metodología): Mediante herramientas de vigilancia tecnológica y analítica de datos, este estudio expone una serie de retos y oportunidades para enfrentar esta amenaza y mejorar el desempeño regional resiliente. (Resultados): Todos los países han firmado acuerdos y han hecho declaratorias sobre política pública para la resiliencia climática, empero persisten fallas históricas y estructurales, así como pasivos ambientales relacionados con la reducción de emisiones de gases de efecto invernadero y la fuerte dependencia por el uso de combustibles fósiles. En contraste, Centroamérica goza de una matriz de oportunidades para aumentar la ambición climática, cuenta con diversas fuentes de energía renovable, mecanismos para incentivar el pago por servicios ambientales y acciones para impulsar la economía circular y la bioeconomía. (Conclusiones): La agenda regional no se conecta con el suficiente blindaje climático que se requiere para contrarrestar los rigores de la era de la ebullición. De estos balances, y según la evidencia científica, se plantea una hoja de ruta con acciones climáticamente inteligentes y socialmente inclusivas. (Recomendaciones): Se sugiere crear un observatorio regional sobre resiliencia climática, (OR2C), para el monitoreo, investigación y educación sobre la era de la ebullición.

Resumen El manejo y modificación del medio ambiente durante miles de años dio como resultado un paisaje fuertemente antropizado en la región este de Uruguay, caracterizado por la presencia de cientos de montículos de gran relevancia arqueológica y ambiental. Este artículo evalúa la vulnerabilidad y los riesgos que enfrentan los montículos de tierra de origen indígena dentro del contexto de producción agrícola en la región de India Muerta Uruguay. Se utiliza una metodología de evaluación de la vulnerabilidad, que pondera los factores de riesgo y resistencia de cada estructura monticular a partir de la confección de un formulario de evaluación de vulnerabilidad, llamado VEF por sus siglas en inglés. Los resultados alcanzados indican que son altamente vulnerables a los impactos de la producción agrícola desarrollada en la región. La expansión de los cultivos intensivos, particularmente de arroz, así como la ganadería bovina, produce un impacto negativo, generando incluso la destrucción de estos elementos del paisaje. La valoración de riesgos y vulnerabilidad implementada en este estudio proporciona indicadores concretos para la evaluación, seguimiento y conservación del patrimonio arqueológico en los paisajes agrícolas, que puede ser integrada a otros indicadores de uso común en la gestión ambiental y la planificación territorial.

Abstract The management and modification of the environment over thousands of years has resulted in a strongly anthropized landscape in the eastern region of Uruguay, characterized by the presence of hundreds of mounds of great archaeological and environmental relevance. This article evaluates the vulnerability and risks faced by indigenous earth mounds within the context of agricultural production in the India Muerta region of Uruguay. A vulnerability assessment methodology is used, which weighs the risk and resistance factors of each mound based on the creation of a vulnerability evaluation form (VEF). The results indicate that they are highly vulnerable to the impacts of agricultural production in the region. The expansion of intensive crops, particularly rice, as well as cattle farming, has a negative impact, even causing the destruction of these landscape elements. The risk and vulnerability assessment implemented in this study provides concrete indicators for the evaluation, monitoring, and conservation of archaeological heritage in agricultural landscapes, which can be integrated with other commonly used indicators in environmental management and territorial planning.

Pesticide residues and heavy metal content of cassava, yam, cocoyam, potato, water yam and carrot were evaluated by gas chromatography-mass spectrometry and atomic absorption spectroscopy. The detected pesticide residues in the samples were 2,4-dichlorophenoxyacetic acid, glyphosate, hexachlorobenzene (HCB), dichlorobiphenyl, aldrin, endosulfan, profenofos, g-chlordane, carbofuran, biphenyl, heptachlor, lindane and t-Nonachlor. The concentration of HCB ranged between 0.0799 ± 0.06 mg/kg and 0.1596 ± 0.00 mg/kg, which was greater than the permitted maximum limit of 0.5 mg/kg established by the US Environmental Protection Agency. The concentration of aldrin and profenofos detected was lower than the predetermined maximum allowed limits. Endosulfan concentrations in cocoyam (0.2500 mg/kg) and potato (0.3265 mg/kg) were higher than the limits allowed by the Canadian Department of Industrial Research. The heavy metals detected in these samples include cobalt, nickel, lead, manganese, chromium, arsenic and mercury in at least one of the samples evaluated. There was not much difference between the concentration of cobalt in yam (0.036 mg/kg) and the maximum allowed concentration (0.043 mg/kg). Lead was detected in potatoes and carrots but was below detectable concentration in cassava, yam, cocoyam and water yam. Similarly, cocoyam was found to have a significant mercury content (0.658 mg/kg), but mercury content was below detectable concentrations in cassava, yam and water yam. SIGNIFICANCE: Heavy metal pollutants and pesticide residues can impair human health, and their presence in food can cause various illnesses and health issues. It is important to prevent exposure to these contaminants and ensure that food is safe by identifying and monitoring them. Farmers may provide consumers with more assurance that their products are safe by identifying and monitoring pesticide residues and heavy metal contamination in these food crops. Overall, it is crucial to find and monitor pesticide residues and heavy metal contamination in food to safeguard customer confidence, ensure legal compliance and preserve human health.
