Workshop CV Dust Atmospheric Aerosols in Cape Verde Region. Aveiro, 11 Janeiro 2013.
International Congresso on Environmental Health (ICEH 2012). Lisboa, 29 Maio – 1 Junho.
European Aerosol Conference. Granada, Spain, 2-7 September 2012. ; > huge amounts of mineral dust are emitted every year from the Sahara desert to the atmosphere; > optical parameters of mineral aerosols determine the direct interaction of solar and terrestrial radiation in the atmosphere through scattering and absorption; > mineral dust has a great impact on cloud formation leading to additional indirect radi...
Simultaneous measurements of outdoor and indoor pollution were performed at three schools in Lisbon. Volatile organic compounds (VOCs), formaldehyde and NO2 were passively monitored over a two-week period. Bacterial and fungal colony-forming units and comfort parameters were also monitored at classrooms and playgrounds. The highest indoor levels of CO2 (2666 μg/m³), NO2 (40.3 μg/m³), VOCs (10.3 μ...
No âmbito do projecto de investigação POCI/AMB/59174/2004, desenvolveu-se um estudo preliminar de avaliação da influência da vegetação urbana no ambiente sonoro, da cidade de Bragança. A metodologia adoptada assentou na caracterização do ambiente acústico quer à escala urbana quer à escala do espaço verde, na realização de ensaios de avaliação da contribuição da vegetação na atenuação dos níveis de ruído, atrav...
Urban green areas have the potential to attenuate some of the negative effects of urbanisation, making cities a more pleasant place to live in. In addition to aesthetic value, green spaces improve air quality, reduce noise levels and generate more comfortable micro-climatic conditions, among other benefits, contributing to urban quality of life. GreenUrbe (POCI/AMB/59174/2004) – The Impacts of Green Spaces on U...
Copyright © 2001 Published by Elsevier Ltd. ; Ground-level concentrations of particulate matter with less than 10μm in diameter were measured in Azores Archipelago, mid-North Atlantic Ocean. Three intensive research campaigns took place between April and August 99. Observed average concentrations were 3.28±2.16 μgmˉ³ for non-sea-salt sulphate, 0.98±0.72μgmˉ³ for nitrate and 0.57±0.44μgmˉ³ for ammonium. The ave...
Proceedings of the NATO Advanced Study Institute, held in Kolympari, Crete, Greece, from 15-24 May 1999. ; Copyright © 2000 Kluwer Academic Publishers. ; Understanding the physical and chemical properties of marine aerosol particles is crucial because of the role these particles play in a number of atmospheric processes. Marine aerosols affect climate directly through scattering and absorption of radiation an...
17º Encontro Nacional da Sociedade Portuguesa de Química. Lisboa, 1-3 Março 2000. ; O sulfureto de dimetilo (DMS) é o composto de enxofre volátil mais abundante em águas marinhas superficiais, tendo origem na decomposição do propionato de dimetilsulfónio (DMSP), um composto com uma função reguladora do potencial osmótico em diversas espécies de microalgas. Regra geral, as águas marinhas encontram-se saturadas ...
