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...
Gut and faecal bacterial community of the terrestrial isopod porcellionides pru...
Oliveira, Jacinta M. M.; Henriques, Isabel; Read, Daniel S.; Gweon, Hyun S.; Morgado, Rui G.; Peixoto, Sara; Correia, António; Soares, Amadeu M. V. M.This work aimed to characterize the gut and faeces bacterial communities (BC) of Porcellionides pruinosus using high-throughput sequencing. Isopods were collected from the field and kept in laboratory conditions similar to those normally applied in ecotoxicology tests. Faeces and purged guts of isopods (n=3 × 30) were analysed by pyrosequencing the V3-V4 region of 16 S rRNA encoding gene. Results showed that gu...
Unravelling the molecular mechanisms of nickel in woodlice
Ferreira, Nuno G. C.; Morgado, Rui G.; Cunha, Luís; Novo, Marta; Soares, Amadeu M. V. M.; Morgan, Andrew J.; Loureiro, Susana; Kille, PeterDuring the last few years, there has been an alarming increase in the amount of nickel (Ni) being released into the environment, primarily due to its use in the production of stainless steel but also from other sources such as batteries manufacturing and consequent disposal. The established biotic ligand models provide precise estimates for Ni bioavailability, in contrast, studies describing the mechanisms unde...
Changes in Soil Ecosystem Structure and Functions Due to Soil Contamination
Morgado, Rui G.; Loureiro, Susana; Gonzalez-Alcaraz, Maria NazaretSoil ecosystems are nowadays exposed to several physical, chemical and biological stressors, which are directly or indirectly related to anthropogenic activities. This chapter covers how contaminants affect the soil ecosystem structure, changing soil functions and services. Soil ecosystem structure is constituted by dynamic interactive abiotic and biotic compartments, dependent on major key factors like water a...
