Towards safer edible insects: assessing contaminant bioaccumulation and depurat...
Cardoso, Diogo N.; Alvito, Paula; de Boevre, Marthe; Silva, Ana Rita; Pinto, José; Rodrigues, Ana; Prodana, Marija; Silva, Patricia; Mostafaie, AmidThe integration of insects into sustainable food and feed chains demands a robust evaluation of their capacity to accumulate and eliminate contaminants. Understanding these dynamics is fundamental to ensuring consumer safety and supporting the development of regulatory standards for insect-derived products. This study assessed the bioaccumulation and depuration kinetics of metal(loid)s (As, Cd, Pb) and mycotoxi...
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/...

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...
Effects of climate conditions on the avoidance behavior of Folsomia candida and...
Malheiro, Catarina; Cardoso, Diogo N.; Loureiro, Susana; González-Alcaraz, M. NazaretGlobal climate changes are predicted for the 21st century. Alterations in soil contaminants' availability and soil invertebrates' behavior are expected, which may interfere with the avoidance capacity that invertebrates may have towards contaminated soils and, therefore, compromise their role in soil functioning. This study aimed to assess the individual effects of air temperature, ultraviolet (UV) radiation an...
Assessing the acute and chronic toxicity of exposure to naturally occurring oil...
Cardoso, Diogo N.; Soares, Amadeu M. V. M.; Wrona, Frederick J.; Loureiro, SusanaIn the Athabasca region, the oil sands are located at or near the surface making open-pit mining viable. In addition, the Athabasca River and its tributaries flow through these oil sands deposits, thereby receiving bitumen-associated contaminants through natural fluvial erosional and weathering processes. A key knowledge gap has been related to understanding both the magnitude and significance of the toxicologi...
Soil moisture influences the avoidance behavior of invertebrate species in anth...
Gonzalez-Alcaraz, Maria Nazaret; Malheiro, Catarina; Cardoso, Diogo N.; Loureiro, SusanaWater availability is paramount in the response of soil invertebrates towards stress situations. This study aimed to evaluate the effects of forecasted soil moisture scenarios on the avoidance behavior of two invertebrate species (the arthropod Folsomia candida and the soft-bodied oligochaete Enchytraeus crypticus) in soils degraded by different types of anthropogenic metal(loid) contamination (mining soil and ...
Mercury accumulation from food decreases collembolans' growth
Cardoso, Diogo N.; Ferreira, Nuno G. C.; Tourinho, Paula S.; Santos, Cátia; Soares, Amadeu M. V. M.; Loureiro, SusanaIn the terrestrial environment, mercury (Hg) contamination can be originated from different inorganic and metal-organic sources, redistributed and transformed in soils. In the present study, the effects of contaminated food with environmentally relevant concentrations of Hg were evaluated in the soil-dwelling invertebrate Folsomia candida. Changes in growth rate and Hg bioaccumulation levels were observed at di...
