| Spanish abstract | Se midieron concentraciones de PM10 tanto en interiores como exteriores en 10 edificios residenciales de Phitsanulok, Tailandia, durante las temporadas de seca y lluvias de 2014. Además, se analizaron siete metales traza en el PM10: Zn, Fe, Pb, Cd, Ni, Cu y Cr. Las concentraciones mensuales intra y extramuros de PM10 fueron de 41.5 a 105.3 µg m–3 y de 95.2 a 145.1 µg m–3, respectivamente. Las concentraciones de PM10 fueron significativamente mayores durante la temporada seca, en comparación con la temporada húmeda. Las razones interior/exterior fueron menores a uno, lo cual indica que el material particulado se origina en ambientes exteriores. En general, las concentraciones medias de metales pesados en el PM10 variaron de 0.2 a 2.7 y de 0.5 a 7.1 µg m–3 para el ambiente interior y el exterior, respectivamente. En el PM10 de interiores se encontró una fuerte correlación positiva entre Zn y Cu, Zn y Ni, y Cu y Ni. Asimismo, se encontró una fuerte correlación entre Zn y Ni, Pb y Cu, Cu y Ni, Cd y Ni, y Zn y Cu en exteriores. Los factores de enriquecimiento de Zn, Cu, Pb, Cr y Ni fueron menores a uno, lo cual sugiere que los metales en el PM10 de interiores se originaron en materiales de la corteza. En cuanto a la valoración de riesgos sanitarios, se determinó mediante una evaluación de riesgos con un sistema integrado de información, que el Cr implica el mayor riesgo de cáncer |
| English abstract | The concentrations of PM10 were measured both indoors and outdoors at 10 roadside residential buildings in Phitsanulok, Thailand during the dry and wet seasons of 2014. Seven trace metals (Zn, Fe, Pb, Cd, Ni, Cu and Cr) were also analysed in PM10. The monthly average concentrations of indoor and outdoor PM10 were 41.5 to 105.3 µg m–3 and 95.2 to 145.1 µg m–3, respectively. PM10 concentrations were significantly higher during the dry season compared to the wet season. The indoor/outdoor (I/O) ratios were less than one indicating that the particulate matter originates from the outdoor environment. Overall, the average concentrations of heavy metals in PM10 ranged from 0.2 to 2.7 µg m–3 and 0.5 to 7.1 µg m–3 for the indoor and outdoor environments, respectively. A strong positive correlation in indoor PM10 was found between Zn and Cu, Zn and Ni, and Cu and Ni. Zn and Ni, Pb and Cu, Cu and Ni, Cd and Ni, and Zn and Cu showed strong positive correlations in the outdoor environment. The enrichment factors of Zn, Cu, Pb, Cr and Ni were less than one suggesting that the metals in indoor PM10 have originated from crustal materials. For the health risk assessment, Cr was found to have the highest excess cancer risk in an evaluation using an Integrated Risk Information System |
