First approach to assess the effects of nanoplastics on the soil species Folsom...
Barreto, Ângela; Santos, Joana; Almeida, Lara; Tavares, Vítor; Pinto, Edgar; Celeiro, Maria; Garcia-Jares, Carmen; Maria, Vera L.The terrestrial environment is one of the main recipients of plastic waste. However, limited research has been performed on soil contamination by plastics and even less assessing the effects of nanoplastics (NPls). Behind the potential toxicity caused per se, NPls are recognized vectors of other environmental harmful contaminants. Therefore, the main aim of the present study is to understand whether the toxicit...
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...
Toxicity of boron and vanadium nanoparticles on Danio rerio embryos - phenotypi...
Santos, Joana; Barreto, Ângela; Almeida, Célia; Azevedo, Cátia; Domingues, Inês; Amorim, Mónica J. B.; Maria, Vera L.Engineered nanoparticles (NPs) are emerging contaminants of concern and it is important to understand their environmental behavior and ecological risks to exposed organisms. Despite their ubiquitous presence in the environment, there is little information about the hazards of certain NPs, such as boron (BNPs) and vanadium (VNPs). The aim of the present research was to investigate the effects of commercial BNPs ...
Effects of the human pharmaceutical gemfibrozil on fish Sparus aurata
Barreto, Ângela; Luís, Luís; Soares, Amadeu; Hylland, Ketil; Loureiro, Susana; Oliveira, MiguelThe growing use of pharmaceutical products is becoming a new environmental problem. The occurrence and fate of pharmaceutically active compounds in the aquatic environment has been recognized as one of the emerging issues in environmental chemistry. Blood lipid lowering agents are among the most commonly found drugs in the aquatic environment. Gemfibrozil, one of the most frequently detected pharmaceuticals fro...
Behavior of colloidal gold nanoparticles in different ionic strength media
Barreto, Ângela; Luis, Luis G.; Girão, Ana V.; Trindade, Tito; Soares, Amadeu M. V. M.; Oliveira, MiguelThe increased applications of engineered nanoparticles (NPs) may lead to environmental release and transport to estuarine environments where NPs are expected to aggregate/agglomerate with increasing ionic strength. However, more stable NPs that may be resistant to high ionic strength media and more dispersed in the aquatic environment are being synthesized. Thus, understanding colloidal NPs’ behavior in differe...
