“…We state that the increased concentration of the surfactants in this area indicates an increased presence of the septic tanks (the households without a connection to the public sewerage). The concentration of the surfactants is also above the limit at other sampling points (2)(3)(4). The reason may be the remnants of industrial activity (mining) in Horná Nitra, which is mentioned as a possible source of the environmental contamination in the State of the Environmental Report (2022).…”

In order to keep the home and occupational environment clean and noninfectious, the consumption of the cleaners and disinfectants, including cosmetics, is increasing. Excessive use of the products results in their accumulation in an aquatic environment. The conventional wastewater treatment plants are unable to effectively remove the emergent pollutants, including the personal care products. The article is focused on the monitoring the presence of the personal care products in surface waters in two river basins in the Slovak Republic, in terms of the surfactant content. Ecotoxicological evaluation of the selected samples from monitored river basins is performed by an acute toxicity test using the test organism Daphnia magna. The monitoring results indicate the presence of the personal care products in the aquatic environment, where pose an ecological and environmental risk. Monitoring in the Hron and Nitra river basins confirmed contamination with the surfactants, to which the measures related to the COVID-19 pandemic contributed. The content of the surfactants in the personal care products is significant and their impact on the aquatic environment is not sufficiently monitored.

The present study demonstrates the synthesis and application of Ag/ZnO powder films (thickness of 4 μm) as photocatalysts for natural sunlight and ultraviolet (UV, 315–400 nm) irradiation. The synthesis procedure is simple and eco-friendly, based on the photo-fixation of silver ions onto commercial ZnO powder via UV illumination for the first time. The photocatalytic efficiency of the newly developed films is evaluated through degradation of paracetamol in distilled and drinking water. Our experimental evidences show that the Ag/ZnO nanostructure films are more active than pristine ZnO films in the photodegradation process. Namely, the photocatalytic efficiency of the films modified with 10−2 M concentration of silver ions achieve the highest degradation (D) percentages for paracetamol in both types of water (Ddistilled = 80.97%, Ddrinking = 82.5%) under natural sunlight. Under UV exposure, the degradation percentages are slightly lower but still higher than those achieved by pure ZnO films (Ddistilled = 53.13%, Ddrinking = 61.87%). It is found that the photocatalytic activity grows in direct proportion to the concentration of Ag+ ions: ZnO < Ag 10−4/ZnO < Ag 10−3/ZnO < Ag 10−2/ZnO. Scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, UV–vis diffuse reflectance and photoluminescence spectroscopy are used to characterize the as-prepared ZnO and Ag/ZnO nanostructures. The improved photocatalytic performance of the Ag/ZnO films is mostly attributed to the combination of excited electron transfer from ZnO to Ag and the inhibition of photogenerated electron–hole pair recombination. Furthermore, Ag/ZnO nanostructure films can retain their photocatalytic activity after three cycles of use, highlighting their potential practical application for the treatment of pharmaceutical wastewater in real-world scenarios where natural sunlight is often more readily available than artificial UV light.

“…A contaminação aquática por medicamentos é proveniente do descarte indevido e da própria metabolização e absorção incompleta da dose administrada (DI MARCANTONIO et al, 2021). Apesar de seu uso ser indispensável é necessário o desenvolvimento de metodologias que permitam a sua remoção do meio ambiente (KHAN et al, 2021).…”

A utilização de medicamentos cresce exponencialmente no mundo e, por vezes, devido ao seu metabolismo incompleto, essas subtâncias como a furosemida são excretadas na sua forma inalterada. As técnicas convencionais de tratamento de efluentes atualmente empregadas mostram-se ineficientes à remoção deste microcontaminante, permitindo que retorne ao consumo. Assim, a adsorção utilizando nanomateriais, como o óxido de grafeno (GO) , mostra-se uma alternativa à remoção desse poluente aquático. A incorporação de nanopartículas magnéticas na estrutura do GO possibilita eliminar etapas, como centrifugação e filtração, necessárias para adsorventes convencionais. Tendo em vista as excelentes propriedades do adsorvente mencionado, o presente trabalho visa realizar um estudo de adsorção para a remoção de furosemida, utilizando GO e GO magnético (GO•Fe3O4) com diferentes proporções de magnetita incorporada.
