A comprehensive ecotoxicological evaluation of a treated olive mill wastewater ...
Pinto, José N.; Pereira, Andreia; Silva, Ana Rita R.; Cardoso, Diogo N.; Mostafaie, Amid; Campos, Fábio; Rehan, Iryna; Moreira, Olga; Lopes, Ivã GuidiniOlive mill wastewaters (OMWWs) are an environmental problem in the Mediterranean region, and it is crucial to explore strategies for their treatment and repurposing. The chemical precipitation technique (CPT) has been presented as a cost-effective wastewater treatment solution that might be applied to OMWW. The CPT-resulting precipitant subproducts (sludge) may be reprocessed (e.g., agricultural fertilizer and/...
Structural and functional shifts in the microbial community of a heavy metal-co...
Silva, Isabel; Alves, Marta; Malheiro, Catarina; Silva, Ana Rita R.; Loureiro, Susana; Henriques, Isabel; González-Alcaraz, M. NazaretThe interplay between metal contamination and climate change may exacerbate the negative impact on the soil microbiome and, consequently, on soil health and ecosystem services. We assessed the response of the microbial community of a heavy metal-contaminated soil when exposed to short-term (48 h) variations in air temperature, soil humidity or ultraviolet (UV) radiation in the absence and presence of Enchytraeu...
A comprehensive ecotoxicity study of molybdenum disulfide nanosheets versus bul...
Santos, Joana; Barreto, Ângela; Fernandes, Cristiana; Silva, Ana Rita R.; Cardoso, Diogo N.; Pinto, Edgar; Daniel-da-Silva, Ana L.; Maria, Vera L.The increasing use of molybdenum disulfide (MoS2) nanoparticles (NPs) raises concerns regarding their accumulation in soil ecosystems, with limited studies on their impact on soil organisms. Study aim: To unravel the effects of MoS2 nanosheets (two-dimensional (2D) MoS2 NPs) and bulk MoS2 (156, 313, 625, 1250, 2500 mg/kg) on Enchytraeus crypticus and Folsomia candida. The organisms’ survival and avoidance behav...
Improving product safety for edible insects : toxicokinetics of Hg in Tenebrio ...
Cardoso, Diogo N.; Silva, Ana Rita R.; Morgado, Rui G.; Mostafaie, Amid; Pereira, Andreia; Pinto, José; Lopes, Ivã G.; Murta, DanielSustainability, circularity, and Zero Waste policies are timely concepts for policy development and strategies in the European Union (EU) and other global regions. Insects can likely become key players in the bioconversion of waste to valuable material and promise one solution to achieve diverse societal goals. Insects further present strategic opportunities as food products; however, it is necessary to underst...
Ecotoxicological effects of fluvial eroded bitumen sediments from the Alberta o...
Cardoso, Diogo N.; Gonçalves, Sandra F.; Silva, Ana Rita R.; Soares, Amadeu M. V. M.; Wrona, Frederick J.; Loureiro, SusanaTo fully understand the ecological and cumulative effects of mining activities on the surrounding aquatic systems of the Canadian oil sands region, it is essential to understand the consequences of exposure to bitumen-containing soils/sediment from natural geomorphological processes. Both physical and chemical stress on aquatic biota can potentially result from exposure to natural bitumen, resulting from hillsl...
Toxicity assessment of binary mixtures of BP3 with 4-MBC (UV-filters), and BP3 ...
Campos, Diana; Morgado, Rui G.; Silva, Ana Rita R.; Machado, Ana L.; Grabicová, Kateřina; Žlábek, Vladimír; Loureiro, Susana; Soares, Amadeu M. V. M.Personal care products have various organic ultraviolet filters (UV filters) in their composition to increase protection against ultraviolet radiation. Some of these products also contain insect repellents in their formulations. Consequently, these compounds reach freshwater ecosystems, exposing aquatic organisms to a cocktail of anthropogenic contaminants. In this study, the joint effects of two most frequentl...
Short-term responses of soil microbial communities to changes in air temperatur...
Silva, Isabel; Alves, Marta; Malheiro, Catarina; Silva, Ana Rita R.; Loureiro, Susana; Henriques, Isabel; González-Alcaraz, M. NazaretWe analyzed the effects on a soil microbial community of short-term alterations in air temperature, soil moisture and ultraviolet radiation and assessed the role of invertebrates (species Enchytraeus crypticus) in modulating the community’s response to these factors. The reference soil, Lufa 2.2, was incubated for 48 h, with and without invertebrates, under the following conditions: standard (20 °C + 50% water ...

Two-generational effects of Benzophenone-3 on the aquatic midge Chironomus ripa...
Campos, Diana; Silva, Ana Rita R.; Loureiro, Susana; Grabicová, Kateřina; Staňová, Andrea Vojs; Soares, Amadeu M. V. M.; Pestana, João L. T.Organic UV-filters are emergent contaminants continuously released into the aquatic ecosystems. These compounds are persistent showing potential for bioaccumulation. Partial life-cycle tests may underestimate the toxicity of UV-filters especially since these compounds have shown to act as endocrine disruptors. In the present study, the benthic aquatic insect Chironomus riparius was exposed to a gradient of Benz...
Ecotoxicity and genotoxicity of a binary combination of triclosan and carbendaz...
Silva, Ana Rita R.; Cardoso, Diogo N.; Cruz, Andreia; Lourenço, Joana; Mendo, Sónia; Soares, Amadeu M. V. M.; Loureiro, SusanaIn the environment, chemical substances appear as complex mixtures and consequently organisms are exposed to a variety of chemicals from different sources (e.g. wastewater treatment plants, agriculture runoffs). When studying chemical mixtures, there are two conceptual models usually used to predict toxicity: the Independent Action (IA) and Concentration Addition (CA) models. However, deviations from these refe...
