“…In the past two decades, there have been growing concerns about brominated flame retardants (BFRs), many of which exhibit persistence and bioaccumulation properties and have been detected globally (Hites, 2004;Hung et al, 2013). BFRs are extensively used in a variety of products in homes and offices such as electronic equipment, furniture, fabrics, car interiors, and construction materials to slow the spread of fire (Batterman et al, 2009).…”

a b s t r a c tIndoor environments contribute a significant portion of human exposure to brominated flame retardants (BFRs) because of their extensive use in various household products. This study investigates the occurrence of a number of BFRs in the indoor and outdoor air in a megacity in southern China, in which little information on indoor BFRs contamination is available. The estimated total PBDE concentrations ranged from 1.43 to 57 pg/m 3 indoors and from 1.21 to 1522 pg/m 3 outdoors. The indoor concentrations of lower brominated PBDEs that are mainly derived from the technical penta-and octa-BDE mixtures were higher than or comparable to the outdoors, while the indoor levels of DecaBDEs and decabromodiphenyl ethane (DBDPE) were apparently lower than the outdoors. The seasonal variations of BFR concentrations indicated that evaporation from old indoor products is the primary source of Penta-and OctaBDEs in the air, whereas most DecaBDEs and DBDPE concentrations showing weak temperature-dependence are largely released from industrial activities. The PBDE congener profiles in the air were generally similar, which were dominated by BDE209, 28, and 47; whereas the appreciable indooreoutdoor differences in the compositions are possibly due to emission sources, photochemical degradation, or congener-specific transport of BFRs in the indoor and outdoor air. Significant correlations between the indoor and outdoor BFRs were observed suggesting the exchange of BFRs between the two compartments, which are more noticeable for PentaBDEs and DecaBDEs with strong indoor and outdoor emission sources, respectively. This study provides significant insights into the sources of BFRs in urban air in China.

“…Las etapas del método son las siguientes: a) Identificar la meta: esta etapa consiste en definir el objetivo de la aplicación de la metodología. [17,18,19,20,21,22]. d) Asignar un peso a cada factor: a cada factor se le dio un peso de 0 a 1, de acuerdo al porcentaje de participación en el presupuesto o inversión económica total planificada para adecuar un sitio de monitoreo, según los siguientes pesos: (1) seguridad = 0,10; (2) Incidencia de otras fuentes = 0,20; (3) Requerimientos de Espacios = 0,15; (4) Accesibilidad = 0,10; (5) Obstáculos = 0,10; (6) Registro histórico de datos = 0,10; y (7) Grado de Contaminación = 0.25.…”

RESUMENEl monitoreo atmosférico es una de las etapas fundamentales en la identificación de estrategias para minimizar, prevenir y controlar los impactos de la dispersión de contaminantes en el aire, sobre la salud pública y el ambiente. Por tanto, el objetivo principal de este artículo consiste en proponer una metodología para la selección de sitios de monitoreo atmosférico en zonas urbanas afectadas por las emisiones de fuentes móviles. Primero se identificaron los sitios que presentaban mayor flujo vehicular y se priorizaron según los siguientes criterios de selección: seguridad, influencia de otras fuentes, facilidad del montaje de los equipos, accesibilidad al sitio, identificación de barreras y obstáculos, registro histórico de datos y grado de concentración del contaminante, en este caso monóxido de carbono, usando el software CALINE 3. La modelación agrupó datos característicos de las vías, meteorológicos y de flujo vehicular de un año típico de la zona en estudio. A cada uno de estos parámetros le es asignada una valoración cuantitativa, que define los sitios donde se realizará el monitoreo. Como resultado se desarrolló una guía para seleccionar los lugares en donde se puedan desarrollar campañas de monitoreo atmosférico, asociadas a fuentes móviles. La metodología fue aplicada en la ciudad de Cartagena de Indias haciendo uso del modelo de calidad del aire CALINE3.Palabras Clave: CALINE 3; contaminantes atmosféricos; fuentes móviles; sitios de monitoreo atmosférico. ABSTRACTAtmospheric monitoring is one of the fundamental steps in identifying strategies to minimize, prevent and control the impact of the dispersion of pollutants in the air, on public health and the environment. Therefore, the main objective of this article is to propose a methodology for selecting air monitoring sites in urban areas affected by emissions from mobile sources. First, the places with the highest vehicular flow were identified and prioritized according to the following selection criteria: safety, influence of other sources, ease of assembly of equipment, accessibility to the site, identification of barriers and obstacles, historical record of data and degree concentration of the pollutant: in this case carbon monoxide, using CALINE 3 software. The modeling grouped characteristic data related with roads, meteorology and vehicular flow of a typical year of the zone under study. A quantitative assessment is assigned to each of these parameters, which defines the sites where the monitoring will be performed. As a result, it was developed a guide to select those places where atmospheric monitoring campaigns related with mobile sources can be held. This method...

“…Brook et al [163] concluded that current air quality management plans lack the mechanism by which improvements in health and environmental impacts can be documented and assessed. Hsu et al [161] noted the disparity in the extent of ground-based monitoring networks between developed and developing countries, which has also been emphasised for specific pollutants by Engel-Cox et al [164] (particulate matter), Bowman [165] (O 3 ), Hung et al [166] (persistent organic pollutants) and Pirrone et al [167] (mercury). Standardisation of data quality between different monitoring networks to ensure the comparability of the full suite of atmospheric composition measurements collected globally has been highlighted [161].…”

Abstract:Ground-based monitoring networks for evaluating atmospheric composition relevant to impacts on human health and the environment now exist worldwide (according to the United Nations Environment Programme, 48% of countries have an air quality monitoring system). Of course, this has not always been the case. Here, we analyse for the first time the key developments in network coordination and standardisation over the last 150 years that underpin the current implementations of city-scale to global monitoring networks for atmospheric composition. Examples include improvements in respect of site type and site representativeness, measurement methods, quality assurance, and data archiving. From the 1950s, these developments have progressed through two distinct types of network: those designed for the protection of human health, and those designed to increase scientific understanding of atmospheric composition and its interaction with the terrestrial environment. The step changes in network coordination and standardisation have increased confidence in the comparability of measurements made at different sites. Acknowledged limitations in the current state of monitoring networks include a sole focus on compliance monitoring. In the context of the unprecedented volumes of atmospheric composition data now being collected, we suggest the next developments in network standardisation should include more integrated analyses of monitor and other relevant data within "chemical climatology" frameworks that seek to more directly link the impacts, state and drivers of atmospheric composition. These approaches would also enhance the role of monitoring networks in the development and evaluation of air pollution mitigation strategies.
