Hedgehogs (Erinaceus europaeus) as bioindicators of heavy metal(loid) pollution
Jota Baptista, C.; Seixas, F.; Gonzalo-Orden, J. M.; Patinha, C.; Pato, P.; Ferreira da Silva, E.; Casero, M.; Brazio, E.; Brandão, R.; Costa, D.Background: Heavy metal(loid)s pollution is a One Health concern [1]. Hedgehogs (Erinaceus europaeus) are promising candidates for biomonitoring programs, due to their habits, abundance, distribution and resilience [2]. Objective: This work aims to evaluate heavy metal(loid)s pollution, using E. europaeus as a bioindicator. Methods: Necropsies of 46 hedgehogs from three distinct rescue centres (CERVAS, LxCRAS a...
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 ...
87Sr/86Sr dating of the Alcácer do Sal Formation and its correlation with the u...
Ressurreição, R.; Legoinha, P.; Dias, R.; Santos, J.; Ribeiro, S.; Patinha, C.; Miranda, R.The Lower Tagus Basin was subjected to several marine transgressions along the Neogene, related to positive eustatic oscillations and also controlled by the regional tectonic activity. In the Alcácer do SalSines region, previous studies identified an episode of marine sedimentation interpreted as having occurred during the late Serravalian to early Tortonian interval, based on biostratigraphic data. This episod...
Tracing of aerosol sources in an urban environment using chemical, Sr isotope, ...
Duarte, R. M. B. O.; Matos, J. T. V.; Paula, A. S.; Lopes, S. P.; Santos, J. F.; Patinha, C.; Silva, E. F.; Soares, R.; Duarte, A. C.In the framework of two national research projects (ORGANOSOL and CN-linkAIR), fine particulate matter (PM2.5) was sampled for 17 months at an urban location in the Western European Coast. The PM2.5 samples were analyzed for organic carbon (OC), water-soluble organic carbon (WSOC), elemental carbon (EC), major water-soluble inorganic ions, mineralogical, and for the first time in this region, strontium isotope ...
The effect of natural zeolite on microstructure, mechanical and heavy metals ad...
Andrejkovicova, S.; Sudagar, A.; Rocha, J.; Patinha, C.; Hajjaji, W.; Ferreira da Silva, E.; Velosa, A.; Rocha, F.This work investigates the effect of clinoptilolite, a natural zeolite, as filler on the mechanical performance and heavy metal's adsorption capacity of the metakaolin-based geopolymers. Clinoptilolite was chosen as an inexpensive additive with high adsorption capacity, replacing metakaolin (0, 25, 50 and 75%) in the synthesis of four different geopolymers (MK100, MK75, MK50 and MK25, respectively). To produce ...

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...
Tracing of aerosol sources in an urban environment using carbonaceous, major io...
Paula, A.; Lopes, S.; Ribeiro, S.; Santos, J. F.; Patinha, C.; Silva, E. A. Ferreira da; Soares, R.; Duarte, R.; Duarte, A.Understanding the chemical composition of atmospheric particulate matter (PM), particularly with a diameter less than 2.5 μm (PM2.5), has became an emergent topic in atmospheric research due to its relation to climate change and serious health issues. In this study, a comprehensive assessment of the carbonaceous (organic carbon, water-soluble organic carbon, elemental carbon), major water-soluble inorganic ions...
Geochemistry, mineralogy, solid-phase fractionation and oral bioaccessibility o...
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...
Lead availability in soils from Portugal's Centre Region with special reference...
Patinha, C.; Reis, Amélia P.; Dias, Ana Cláudia; Cachada, A.; Adão, Rui; Martins, H.; Ferreira da Silva, E.; Sousa, A. J.Previous environmental biomonitoring studies indicated higher environmental lead (Pb) pollution levels at the districts of Aveiro and Leiria (Portugal). In evaluating the risk for human health, which is associated with contaminated soils after oral uptake, total soil concentrations have generally been held against criteria established from toxicological studies based upon the assumption that the uptake of the c...
