Impact of environmental caffeine contamination in zebrafish: ecotoxicological a...
Pinto, I.; Diogo, B. S.; Antunes, S. C.; Rodrigues, S.Background: Caffeine (CAF) is considered a suitable indicator of anthropogenic contamination of aquatic environments, and several pharmacological and biological effects have been observed in target and non-target organisms [1,2]. Objective: Assess the chronic effects of environmental concentrations of CAF in several biomarker responses in Danio rerio. Methods: After chronic exposure to CAF (0.16, 0.42, 1.09, 2....
The ecotoxicity evaluation of Gens ponds: are the pH values a confounding factor?
Pereira, R.; Diogo, B. S.; Rodrigues, I.; Antunes, S. C.Background: Portuguese polymetallic mining activities were important for local development of economy and ceased in 1970s. However, these activities leave amounts of tailings susceptible to erosion and chemical weathering, representing a potential risk to the environment, due to a high concentration of heavy metals and acidic mine drainages [1,2]. Gens ponds arose due to open pit mining in a gold-antimony mine ...
Ecotoxicological effects of elutriates from coal mining waste in Lactuca sativa...
Rajnauth, A.; Diogo, B. S.; Marques, J. E.; Flores, D.; Antunes, S. C.Background: Fojo mine (Castelo de Paiva, Douro Carboniferous Basin) was used for anthracite exploitation until 1994, resulting in the production of coal waste piles without any environmental management [1,2]. In October 2017, a wildfire triggered the ignition of some of these waste piles. The extinguishing process of the fire included the remobilization of the coal mining residues using water mixed with a cooli...
The unknown acute toxicity of the antibiotic sulfamethoxazole
Diogo, B. S.; Rodrigues, S.; Antunes, S. C.Background: Sulfamethoxazole (SMX) is one of the most used antibiotics in the last 50 years, applied to humans, veterinary medicines, and aquaculture purposes [1]. Detected in different environmental matrices this antibiotic can pose a risk to aquatic ecosystems and contribute to the spread of antimicrobial resistance [2,3]. In addition, SMX has already been included in the 3rd Priority Substances Watch Lis...
