Ecotoxicity of the non-dioxin-like PCB-153 in the model marine diatom Phaeodact...
Duarte, Bernardo; Cardoso, João; Feijão, Eduardo; Carreiras, João Albuquerque; Cruz De Carvalho, Ricardo; Matos, Ana Rita; Fonseca, Vanessa F.Despite the ban on polychlorinated biphenyls (PCBs) in developed countries since the 1930s, their persistence and use endured in developing countries, with reported toxic effects on various organisms. PCB congener 153 (PCB-153, 2, 2′, 4, 4′, 5, 5′–hexachlorobiphenyl) is notably prevalent in marine biota. However, its mode of action and impact on primary marine diatoms are not well documented. Phaeodactylum tric...
Roadmap to sustainably develop the European seaweed industry
Jueterbock, Alexander; Hoarau-Heemstra, Hindertje; Wigger, Karin; Duarte, Bernardo; Bruckner, Christian; Chapman, Annelise; Duan, DelinHow to build a sustainable seaweed industry is important in Europe's quest to produce 8 million tons of seaweed by 2030. Based on interviews with industry representatives and an expert-workshop, we developed an interdisciplinary roadmap that addresses sustainable development holistically. We argue that sustainable practices must leverage synergies with existing industries (e.g. IMTA systems, offshore wind farms...
Impact of mineral and organic fertilisation practices on elemental authenticity...
Duarte, Bernardo; Carreiras, João Albuquerque; Melo, Juliana; Gonçalves, Marta; Silva, Anabela B.; de Sousa, Miguel LeãoMarket demand, climate change and soil degradation force producers to maintain the productivity and quality of high-market-value products, such as Protected Geographical Indication (PGI) fruits. “Maçã de Alcobaça” apples produced in the central-western part of Portugal, namely the variety Royal Gala, one of the PGI varieties with higher demand, are among those with higher requirements in terms of fertilization ...
Persistent Organic Pollutants in Tagus Estuary Salt Marshes: Patterns of Contam...
Cruz De Carvalho, Ricardo; Cardoso, João; Carreiras, João Albuquerque; Santos, Paula; Palma, Carla; Duarte, BernardoThe presence of anthropogenic compounds, including organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), was studied in three salt marshes within the Tagus estuary, Portugal, along an anthropogenic pressure gradient. Results revealed differences in OCPs and PCBs among the marshes, with differing concentration levels. Specifically, one marsh, with surrounding agricultural activity, showed the hi...
Marine microbial community taxonomic and functional indicators to volcanic and ...
Duarte, Bernardo; Cruz-Silva, Ana; Feijão, Eduardo; Pereira, Marcelo; Nunes, Mónica; Figueiredo, Andreia; Matos, Ana Rita; Dias, RicardoIn recent years, the growth in Antarctic tourism has stimulated research on the anthropogenic impacts on the region, boosted by advances in OMIC technologies applied to polar microbial communities. This study aimed to assess the human impacts on marine prokaryotic and viral communities of Deception Island by identifying potential taxonomic, functional, and resistome indicators of both anthropogenic and natural/...

Impact of Elevated Atmospheric CO2 in Spartina maritima Rhizosphere Extracellul...
Duarte, Bernardo; Baeta, Alexandra; Marques, João Carlos; Caçador, IsabelAtmospheric CO2 enrichment, which is caused to a large extent by anthropogenic activities, is known to interfere with sediment microbial communities via plant rhizospheres. The present work aimed to evaluate this interaction in Spartina maritima ((Curtis) Fernald.) rhizosediments, aiming to depict the impacts of atmospheric CO2 increase in the biogeochemical processes occurring in the rhizosphere of this pionee...
Comparison of digestion methods using atomic absorption spectrometry for the de...
Bankaji, Insaf; Kouki, Rim; Dridi, Nesrine; Hidouri, Saida; Duarte, Bernardo; Sleimi, Noomene; Caçador, Isabel; Ferreira, RenataTrace metal elements (TMEs) are among the most important types of pollutants in the environment. Therefore, a precise determination of these contaminants in several environmental components is required for the safety assurance of living organisms. Spectroscopic analysis is an efficient technique employed to detect and determine TME contents in numerous samples. Hence, to achieve reliable and accurate results wh...
Cistus ladanifer metal uptake and physiological performance in biochar amended ...
Duarte, Bernardo; Pires, Vanessa; Carreiras, João; Carvalho, Ricardo Cruz de; Pereira, Manuel F.C.; Maurício, António M.; Martins-Dias, SuseteBiochar amendments are known to have a considerable influence on phytoremediation processes. Considering this, in the present work, we aimed to evaluate the effect of biochar amendments in metal-contaminated mine soils focusing on the metal uptake by Cistus ladanifer and its physiological consequences. Plants were exposed to mine soils with different biochar supplementations and the plant's physiological perfor...
Photosythetic responses of two salt-tolerant plants, Tamarix gallica and Arthro...
Sghaier, Dhouha Belhaj; Pedro, Sílvia; Duarte, Bernardo; Caçador, Isabel; Sleimi, NoomeneIn recent years, the level of arsenic in soil has increased dramatically in many countries, which has raised concern to develop new environmentally friendly techniques to solve problems such as arsenic, which is highly soluble and has toxic effects. It is an environmental issue and a global health matter because of its poisonous and carcinogenic characteristics. It is known that arsenic influenced farmland and ...
