- 87Sr/86Sr dating of the Alcácer do Sal Formation (upper Miocene, mainland Portugal)Publication . Ressurreição, Ricardo; Legoinha, Paulo; Dias, Ruben Pereira; Santos, José Francisco; Ribeiro, Sara; Patinha, Carla; Miranda, RuiThe 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 episode is represented in the Alcácer do Sal Formation. The study of the SMS-12- 01B borehole, drilled for mineral prospection purposes, located about 10 km NNE of Melides, allowed the identification of a 3 m thick layer of sediments containing marine fossils. 87Sr/86Sr determinations of oyster shells point to deposition about 11.5 Ma ago, validating previous proposals for the age of the formation. These data correspond to the first numerical ages obtained for the Alcácer do Sal Formation, allowing a solid correlation with other known marine units in the Lower Tagus and Algarve basins related to the same transgression episode
- URBSOIL-LISBON-Geoquímica dos solos urbanos de Lisboa: caracterização e cartografia, suporte para futuros estudos de saúde humana: resultados preliminaresPublication . Prazeres, Cátia; Batista, Maria Joao; Patinha, Carla; Reis, A. P.; Dias, A. C.; Cachada, A.; Silva, E. Ferreira da; Sousa, A. J.; Figueira, R.; Sérgio, C.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 principal. Os primeiros resultados sobre concentrações de elementos químicos para os solos urbanos de Lisboa apontam para uma exposição esparsa na cidade de alguns dos elementos químicos inorgânicos, mas havendo por vezes um zonamento por tipologia de local ou de elemento químico. Foram definidos quatro grupos de pontos de amostragem consoante o tipo de uso, e escolhidos para uma análise mais próxima alguns elementos considerados tendencialmente de input antrópico e que se relacionam com a saúde humana.
- Introducing "UrbanEnviron@Lisbon 2008" a GIS-platform for environmental and human health data managementPublication .

- Urban geochemistry of lead in gardens, playgrounds and schoolyards of Lisbon, Portugal : assessing exposure and risk to human healthPublication . 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 da; Rocha, FernandoTo 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 EPA guidelines using a sub-set of 19 topsoil and 8 outdoor dusts, out of a total of 51 samples, incorporating oral bioaccessibility measurements using the Unified BARGE Method developed by the Bioaccessibility Research Group of Europe. The objectives are: (i) interpretation of soil and dust oral bioaccessibility measurements; (ii) assessment of site-specific exposure and non-carcinogenic risk posed by lead; (iii) hazard assessment for urban soil and dust with respect to children playing in outdoor recreational areas. The results show that significant fractions of Pb occur in bioaccessible forms, 24–100% in soils and 35–100% in dusts and the associated risk is greater for dust ingestion than for soil ingestion in Lisbon city recreational areas.
- Effects of application of eucalyptus leaf biomass on soil quality: a field trialPublication . Teixeira, Tiago; Cachada, Anabela; Pato, Pedro; Patinha, CarlaABSTRACT: Approximately 30% of Portuguese forests are occupied by eucalyptus (Eucalyptus globulus). As this is a highly flammable invasive species, it is essential to control its proliferation. Thus, the PEST(bio) CIDE project, based on a circular economy perspective, aims to explore the phytotoxic potential of eucalyptus leaves, using its leaf biomass as an effective and environmentally safe biocide, and its use as a corrective to improve soil properties. It is also expected that the introduction of biomass into the soil will contribute to increase carbon reserves and soil fertility. Thus, it is possible to associate an economic benefit with better management of post-fire regenerated eucalyptus areas. Due to this, a field trial was carried out to test the effect of biomass application on the soil’s physico-chemical properties. The results indicate that incorporating leaves has a positive effect on some soil properties, mainly in terms of increasing organic matter and available macronutrients.
