The use of multivariate statistical analysis of geochemical data for assessing ...
Candeias, C.; Silva, E. Ferreira da; Salgueiro, A. R.; Pereira, H. G.; Reis, A. P.; Patinha, C.; Matos, J. X.; Ávila, P. H.Aljustrel mine is located in SW Portugal, in the western sector of the Iberian Pyrite Belt. The Aljustrel village was developed around the exploitations of massive polymetallic sulphides that occur in the area (4 orebodies mined, 2 in exploration phase). The pyrite ore was extensively exploited from 1850 to 1993, when production was discontinued. A mining restart occurred in 2008, only during a few months. The ...
Investigating relationships between biomarkers of exposure and environmental co...
Reis, A. P.; Costa, S.; Santos, I.; Patinha, C.; Noack, Y.; Wragg, J.; Cave, M.; Sousa, A. J.This study reports on data obtained from a pilot survey focusing on house dust and toenail metal(loids) concentrations in residents living in the industrial city of Estarreja. The study design hereby described aims at investigating relationships between human toenails and both copper and manganese levels in settled house dusts. A total of 21 households and 30 individuals were recruited for the pilot study: 19 h...

Reis, A. P.; Patinha, C.; Wragg, J.; Dias, A. C.; Cave, M.; Sousa, A. J.; Costa, C.; Cachada, A.; Ferreira da Silva, E.; Rocha, F.; Duarte, A.An urban survey of Lisbon, the largest city in Portugal, was carried out to investigate its environmental burden, emphasizing metallic elements and their public health impacts. This paper examines the geochemistry of lead (Pb) and its influence on human health data. A total of 51 soil samples were collected from urban recreational areas used by children to play outdoors. The semi-quantitative analysis of Pb was...

Reis, A. P.; Patinha, Carla; Wragg, J.; Dias, A. C.; Cave, M.; Sousa, A. J.; Batista, Maria Joao; Prazeres, Cátia; Costa, C.; Silva, Eduardo Ferreira daTo assess the impact of potentially harmful elements in soil/dust on the health of children that use urban recreational areas to play outdoors, an urban survey of Lisbon, the largest city in Portugal was carried out, collecting soils and dusts from public gardens, parks, playgrounds and schoolyards. An exposure and risk assessment study for the incidental soil/dust ingestion of lead was carried out based on US ...

Prazeres, Cátia; Batista, Maria Joao; Patinha, Carla; Reis, A. P.; Dias, A. C.; Cachada, A.; Silva, E. Ferreira da; Sousa, A. J.; Figueira, R.A Geologia, e em especial a Geoquímica em ambiente urbano, têm-se revelado ferramentas essenciais não só no estudo dos materiais naturais neste ambiente, como na ligação entre a Geologia e a acção antrópica. Este estudo, com uma metodologia que usa vários meios de amostragem, pretende avaliar quais os elementos químicos que podem intervir num contexto de interacção em que as crianças são tomadas como alvo princ...
Geochemical associations and their spatial patterns of variation in soil data f...
Reis, A. P.; Silva, E. F.; Sousa, A. J.; Patinha, C.; Martins, E.; Guimarães, C.; Azevedo, M. R.; Nogueira, P.This paper discusses the results of a soil geochemical exploration survey in the environs of the Marrancos gold-tungsten deposit, dealing with 144 samples of topsoil, analysed for 53 chemical elements. At this initial stage of the project the main objectives were: (1) to identify associations between chemical elements; (2) to estimate spatial patterns of variation for such associations in the surficial material...
