Article
As soluções baseadas na natureza (Nature-based solutions, NbS) são definidas como soluções tecnológicas inspiradas e suportadas pela natureza que mimetizam os processos naturais, e que contribuem para a resiliência e sustentabilidade das cidades, bem como para a criação de serviços ecossistémicos. Existem várias NbS que podem ser aplicadas no ambie...
Research Proposal
Climate change represents a serious threat in urban environments, and one that is intensified by the significant reduction of natural green areas, bringing several related and negative environmental consequences. Frequent floods and stormwater management difficulties, urban heat islands effects, heat waves, and air pollution are among those negativ...
Research Proposal
Green infrastructure in urban areas has been substantially reduced and replaced by concrete and impermeable surfaces, bringing numerous stormwater management problems. Efficient urban stormwater management systems to reduce rainwater runoff quantity and improve water runoff quality are needed in order to face the present climate change scenario. Gr...
Article
Full-text available
Green roofs have been described as technical solutions to overcome urban environmental problems, such as decrease of vegetation and stormwater management. In the present study, two pilot 20 m2 extensive green roofs were implemented in an urban Mediterranean region, at a 1st storey on a warehouse building structure, in order to test the adequacy of...
Article
Full-text available
Green roofs technology has evolved in the last years as a potential solution to promote vegetation in urban areas. Green roof studies for Mediterranean climates, where extended drought periods in summer contrast with cold and rainy periods in winter, are still scarce. The present research study assesses the use of substrates with different composit...
Conference Paper
Full-text available
O papel da Universidade é plural e diverso, transcendente à geração e transmissão de conhecimento ao nível do ensino superior. Uma aproximação entre as Universidades e as Escolas e a comunidade em geral estimula a curiosidade e inquietude científica, o espírito crítico e o processo criativo quer de alunos quer do cidadão comum. Ao nível universitár...
Article
Full-text available
Aromatic plants such as lavender are stirring the attention of many researchers due to their content in bioactive secondary metabolites that can be used in traditional medicine. However, information regarding naturally occurring lavender associated bacterial endophytes (BE) is limited. To the best of our knowledge, this is the first study which aim...
Article
Full-text available
Green roofs (GRs) are becoming a trend in urban areas, favouring thermal performance of buildings, promoting removal of atmospheric pollutants, and acting as possible water collection spots. Rainwater harvesting systems in buildings can also contribute to the management of stormwater runoff reducing flood peaks. These technologies should be enhance...
Article
Full-text available
Metal contamination of a few aquatic, atmospheric, and soil ecosystems has increased ever since the industrial revolution, owing to discharge of such elements via the effluents of some industrial facilities. Their presence to excessive levels in the environment will eventually lead to serious health problems in higher animals owing to accumulation...
Article
Full-text available
Microorganisms isolated from sites contaminated with heavy metals usually possess a higher removal capacity than strains from regular cultures. Heavy metal-containing soil samples from an industrial dumpsite in Northern Portugal were accordingly collected; following enrichment under metal stress, a consortium of wild microalgae was obtained. Their...
Article
Full-text available
Several aquatic environments have been contaminated with heavy metals dumped via industrial effluents. Numerous studies have been published regarding the removal of single metals from aqueous solutions by microalgal biomass. However, such studies do not reflect the actual problem associated with industrial effluents because usually more than one me...
Chapter
Heavy metal contamination of aquatic ecosystems has been increasing in recent times, owing to disposal of such pollutants in effluents. Their presence to excessive levels leads to serious health problems in living organisms, since they cannot be mineralized to completely innocuous forms. The physicochemical methods, such as chemical precipitation,...
Article
Full-text available
Aquatic environments often contain toxic heavy metals that may enter the food web via uptake by microalgae and eventually cause severe poisoning problems at higher trophic levels. The effects of Cd and Zn cations upon growth of two native green microalgal species, Scenedesmus obliquus and Desmodesmus pleiomorphus (previously isolated from a pollute...
Article
Full-text available
The ability of a wild strain of Scenedesmus obliquus, isolated from a heavy metal-contaminated environment, to remove Cd2+ from aqueous solutions was studied at several initial concentrations. Viable biomass removed metal to a maximum extent of 11.4mgCd/g at 1mgCd/l, with most Cd2+ being adsorbed onto the cell surface. A commercially available stra...
Article
Full-text available
Aquatic environments are often exposed to toxic heavy metals, which gain access to the food chain via microalgae and may cause severe problems at higher trophic levels. However, such a metabolic specificity can be taken advantage of in bioremediation strategies. The potential of a novel wild strain of Scenedesmus obliquus, previously isolated from...
Article
Full-text available
The capacity of microalgae to accumulate heavy metals has been widely investigated for its potential applications in wastewater (bio)treatment. In this study, the ability of Desmodesmus pleiomorphus (strain L), a wild strain isolated from a polluted environment, to remove Cd from aqueous solutions was studied, by exposing its biomass to several Cd...
Article
Full-text available
Microalgae have been proven efficient biological vectors for heavy metal uptake. In order to further study their biosorption potential, a strain of Desmodesmus pleiomorphus (L) was isolated from a strongly contaminated industrial site in Portugal. Under different initial Zn(2+) concentrations, metal removal by that strain reached a maximum of 360 m...
Article
Full-text available
The biochemical composition of microalgae can be modulated through the environmental conditions prevailing during growth. The simultaneous effects of irradiance and temperature on the biochemical composition of Pavlova lutheri were evaluated using an experimental star factorial design. Five levels were tested for each parameter (temperature, 10, 14...
