Caracterización granulométrica y mineralógica de la materia particulada atmosférica en el área cerámica de Castellón

Abstract

[ES] Los dos factores fundamentales al evaluar el comportamiento y el origen de los contaminantes particulados atmosféricos son el tamaño de partícula y la composición. En el presente trabajo se ha realizado una caracterización física y mineralógica del MPS1 de la Plana de Castellón, captando muestras de particulado atmosférico mediante un impactador de cascada, que permite obtener el material en 7 fracciones de tamaño desde partículas inferiores a 0.5 μm a 32 μm. Se han establecido cinco puntos de muestreo: estación Aubicada en línea de costa, estaciones B, C y E localizadas en poblaciones con industria cerámica, y estación D (también denominada rural) situada en una zona de montaña a 30 km. del centro industrial. Los niveles de concentración obtenidos han sido superiores en las áreas cerámicas respecto a la estación litoral en un 25 a 35% para el PST2 y el PM10 3. En las partículas de menor tamaño, los valores para las tres estaciones tienden a igualarse , siendo ligeramente superiores los niveles en las áreas cerámicas en el caso del PM2.5 4, e igual y/o inferior en el PM1 5. En la estación de fondo se han obtenido niveles de concentración muy homogéneos para las partículas de 4 a 32 μm. Se han identificado dos tamaños de partícula característicos, asociados a los niveles máximos de concentración en las áreas cerámicas. La evolución mensual de las concentraciones de partículas enmarcadas en cada uno de estos dos rangos granulométricos ha mostrado diferencias importantes entre las estaciones cerámicas de estudio. Dicha diferenciación se ha asociado a las características topográficas y de ubicación de los puntos respecto al núcleo industrial. El análisis mineralógico ha mostrado una composición muy homogénea en el área cerámica. La distribución granulométrica de las fases minerales ha permitido identificar procesos de aporte natural y antropogénico en el área de estudio.

[EN] Size and composition are two basic parameters to asses the behaviour and the origin of particulate atmospheric contaminants. The monitoring of the levels of atmospheric particles by means of cascade impactor sampler allow to asses the both parameters together. In this work, the physical and the mineralogical characteristics of TPS in the industrial ceramic area of Castellon are described. Samples of airborne particulate were collected by using a cascade impactor sampler . This collector allow to obtain seven fractions of size particle (range:0.5 to 32μm) without filters. Five sampling places were studied. Station A located at coastal line, Station B, Station C and Station E placed at the ceramic industrial area, and Station D (remote station) located at 35Km from the industrial area. The concentration levels, which were obtained, were upper in the ceramic industrial areas than Station A from 35 to 25 % for TPS and PM10.The concentration’s values of particles in the minor range of particle size were similar in the three sampling stations, but they were upper in the PM2.5 fraction and equal in the PM1 fraction. At remote station, the concentration levels, which were obtained, were homogenous for particles from 4 to 32 μm. Two typical ranges of particle size were identified which are associated to the concentration levels in the ceramic industrial areas. This fact due to explain the existence of particle distribution at different levels of height. The mineralogical analysis has shown that there is a homogenous composition in the ceramic industrial area. The maximum values of the mineral contents, in the size particle distributions, has permitted to identify the natural and the human activities source origins in this area.
