“…Moreover, the disparities in the capacity of tree species to capture particulate matter can be attributed to fluctuations in weather conditions associated with diverse traffic patterns and the higher wind speeds characteristic of densely trafficked urban areas. Elevated wind speeds bolster the deposition velocity of PM on roadside vegetation, leading to heightened levels of PM accumulation [70][71][72][73][74]. Chowdhury et al (2022) conducted a study in Bangladesh to investigate particulate matter levels across six different sites.…”

Air pollution is a pressing environmental concern in urban areas, with particulate matter (PM) posing serious health and environmental threats. Urban greening has emerged as a potential solution to capture and retain PM. This study assesses the PM deposition capacity of five common tree species: Morus alba (M. alba), Ailanthus altissima (A. altissima), Platanus orientalis (P. orientalis), Robinia pseudoacacia (R. pseudoacacia), and Ulmus minor (U. minor) in two highly polluted sites in Tehran, Iran. Additionally, this study investigates the accumulation of heavy metals (Ni, Fe, Cd, and Pb), Organic Carbon (OC), Elemental Carbon (EC), and Total Carbon (TC) on the leaves of these tree species. The results demonstrate species-specific differences in PM deposition capacity, with U. minor and M. alba showing high PM retention. A. altissima exhibits strong capability in adsorbing PM 0.1–2.5, while U. minor demonstrates greater retention of PM > 2.5. Moreover, the deposition of heavy metals varies among species, with R. pseudoacacia and A. altissima capturing higher levels. This study highlights the significance of appropriate tree utilization in urban environments against air pollution in order to make the air healthier in major cities. Awareness of the different tree species capacities leads urban planners and policymakers to make intelligent decisions about urban greening initiatives to improve air quality and overall well-being.

“…La dirección y velocidad del viento son importantes para estudios en calidad del aire [24]. En la Figura 8, se muestran las rosas de viento para el periodo monitoreado, observando para julio vientos provenientes mayormente del componente este (E) y este-noreste (ENE) con una frecuencia del 35 y 32 % en julio; 25 y 32 % en agosto; 18 y 22 % en septiembre, respectivamente.…”

El uso de sensores de bajo costo para el estudio de la contaminación atmosférica en ciudades ha aumentado en los últimos años. Este trabajo se realizó con el objetivo de medir los niveles de concentración de PM2.5 en la ciudad de Pamplona y analizar las concentraciones a las cuales la población se ve expuesta, puesto que no se cuenta en la ciudad con una estación de monitoreo oficial. Se utilizaron cuatro sensores de bajo costo de la marca SENSIRION, modelo SPS30, los cuales se ubicaron siguiendo los lineamientos recomendados por la Agencia de Protección Ambiental de los Estados Unidos. Asimismo, se realizaron pruebas estadísticas con los datos y se analizó el comportamiento de las concentraciones de PM2.5 en el periodo de julio a septiembre de 2022. Los resultados del monitoreo muestran que las concentraciones de PM2.5 están muy por debajo del límite máximo permisible de la legislación colombiana de 37 μg/m3 (promedio 24 horas), sin embargo, se observó que, en días festivos como la celebración de la independencia, las concentraciones aumentaron hasta cerca de alcanzar el límite de referencia impuesto por la Organización Mundial de la Salud (15 μg/m3). Además, se observó a través de mapas de distribución espacial que las máximas concentraciones se centran al norte de la ciudad, donde se tiene una mayor densidad del tráfico automotriz y se encuentran los principales centros educativos. De esta forma, este estudió permitió obtener un indicativo de las concentraciones de PM2.5 creando un registro para la gestión de la calidad del aire, así como, una base de información con datos disponibles en la web de acceso público.

This study focuses on the environmental conditions of the Mahanadi Estuary near Paradeep Harbor and the adjacent sea. Data collected from May 2013 to April 2020 from 32 GPS fixed stations was analyzed to assess the water quality in different zones (estuarine, mixed zone, mixed zone south, and mixed zone north) of study area. Parameters such as pH, SST, TSS, nitrite, phosphate, silicate, TOC, chlorophyll, fecal coliform, and heavy metals were used to estimate the Water Quality Index (WQI) for each zone. The study found a deterioration (>30%)in the overall water quality of the Mahanadi Estuary from 2013 to 2020, potentially attributed to river inflows, port activities, and industrial outflows in to the coastal ecosystem. Seasonal variations in temperature, salinity, turbidity, nitrite, nitrate, and ammonia were observed. The water quality showed a deteriorating trend in estuarine, mixed zone, mixed zone south, and mixed zone north. Based on the water quality indices, the ecosystem shows moderate levels of stress. The degraded water quality highlights the need for a targeted mitigation plan to reduce external pressures and enhance the overall ecosystem quality.
