Threats to sustainability in face of post-pandemic scenarios and the war in Ukr...
da Costa, João Pinto; Silva, Ana Luísa; Barcelò, Damià; Rocha-Santos, Teresa; Duarte, ArmandoAs the World slowly emerged from the then-ongoing pandemic, War broke out in Europe with the invasion of Ukraine by Russia. The enduring military conflict in Ukraine has had sweeping consequences at the human, social, economic, and environmental levels, not only for the nations involved but across Europe and globally. Damaged infrastructures, severe disruption of economic activity, and forced migration have led...
Improving of an easy, effective and low-cost method for isolation of microplast...
Vujić, Maja; Vasiljević, Sanja; Rocha-Santos, Teresa; Agbaba, Jasmina; Čepić, Zoran; Radonić, Jelena; Tubić, AaleksandraMicroplastic fibers have been found to be a dominant form of microplastics in water matrixes, and textile industry and domestic washing of synthetic textiles as one of its main sources. Additionally, there is a lack of knowlidge about microplastic fiber release during mechanically drying clothes and textiles due to differences in the isolation of microplastic fiber methods. Limited information available in the ...
Isosorbide and 2,5-Furandicarboxylic Acid Based (Co)Polyesters: Synthesis, Char...
Bouyahya, Chaima; Patrício, Rafael; Paço, Ana; Lima, Mafalda S.; Fonseca, Ana C.; Rocha-Santos, Teresa; Majdoub, Mustapha; Silvestre, Armando J.D.Poly(2,5-furandicarboxylate)s incorporating aliphatic moieties represent a promising family of polyesters, typically entirely based on renewable resources and with tailored properties, notably degradability. This study aims to go beyond by developing poly(isosorbide 2,5-furandicarboxylate-co-dodecanedioate) copolyesters derived from isosorbide (Is), 2,5-furandicarboxylic acid (FDCA), and 1,12-dodecanedioic acid...
A One Health perspective of the impacts of microplastics on animal, human and e...
Prata, Joana C.; da Costa, João P.; Lopes, Isabel; Andrady, Anthony L.; Duarte, Armando C.; Rocha-Santos, TeresaMicroplastics contamination is widespread in the environment leading to the exposure of both humans and other biota. While most studies overemphasize direct toxicity of microplastics, particle concentrations, characteristics and exposure conditions being used in these assays needs to be taken into consideration. For instance, toxicity assays that use concentrations over 100,000 times higher than those expected ...
An urgent call to think globally and act locally on landfill disposable plastic...
Patrício Silva, Ana L.; Prata, Joana C.; Duarte, Armando C.; Barcelò, Damià; Rocha-Santos, TeresaLandfilling and illegal waste disposal have risen to deal with the COVID-19 potentially infectious waste, particularly in developing countries, which aggravates plastic pollution and inherent environmental threats to human and animal health. It is estimated that 3.5 million metric tonnes of masks (equivalent to 601 TIR containers) have been landfilled worldwide in the first year, with the potential to increase ...
Selection of microplastics by Nile Red staining increases environmental sample ...
Prata, Joana C.; da Costa, João P.; Fernandes, António José Silva; da Costa, Florinda Mendes; Duarte, Armando C.; Rocha-Santos, TeresaNile Red staining enables visual identification and quantification of fluorescent particles as a proxy to microplastics at low cost and high throughput, including those of small sizes (≥2 μm), when preceded by proper natural organic matter removal, but providing no chemical characterization. On the other hand, micro-spectroscopy methods allow chemical characterization of particles based on their spectra, essent...
Microplastics and fibers from three areas under different anthropogenic pressur...
Prata, Joana C.; Godoy, Veronica; da Costa, João P.; Calero, Monica; Martín-Lara, M. A.; Duarte, Armando C.; Rocha-Santos, TeresaSources contributing to specific concentration of microplastics and fibers are still not completely understood. This study aimed at assessing the concentrations of microplastics (2-5000 μm) and fibers (18-5667 μm) in three areas of distinct influences in the Douro river, Porto, Portugal: (i) a countryside area; (ii) a wastewater treatment effluent release zone; and (iii) an area in proximity to a boat dock and ...
Effects of spatial and seasonal factors on the characteristics and carbonyl ind...
Prata, Joana C.; Reis, Vanessa; Paço, Ana; Martins, Patrícia; Cruz, Ana; Costa, João P. da; Duarte, Armando C.; Rocha-Santos, TeresaCoastal environments are highly contaminated with plastics of various sizes. In order to understand the distribution and factors influencing (micro)plastics contamination in the environment, sampling of a sandy beach in Costa Nova, Aveiro, Portugal, was conducted by collecting plastic particles and sediments for density separation in transects from the mean low tide line to the dunes, during wet and dry seasons...
An easy method for processing and identification of natural and synthetic micro...
Prata, Joana C.; Castro, Joana L.; da Costa, João P.; Duarte, Armando C.; Cerqueira, Mário; Rocha-Santos, TeresaMicroplastics and microfibers can contaminate every matrix, including in the atmosphere, thus leading to incidental inhalation. However, concentrations of airborne synthetic particle in indoor and outdoor environments are not well understood due to the complexities of sampling, sample processing and identification. This work aims at producing a simple protocol to determine the concentrations of airborne micropl...
Effects of distance to the sea and geomorphological characteristics on the quan...
Godoy, Verónica; Prata, Joana C.; Blázquez, Gabriel; Almendros, Ana Isabel; Duarte, Armando C.; Rocha-Santos, Teresa; Calero, MónicaMicroplastics became an unprecedented challenge and mapping their contamination all over the world is needed in order to establish baseline levels and identify the polymers in order to enhance adequate legislation and policy. The main objective of this study is to demonstrate the existence of microplastic pollution on three beaches on the coast of Granada (Spain), namely La Herradura, Motril Beach and La Rábita...
