“…Aguirre-Martínez et al (2015) reported effects of caffeine on biomarkers of phases I and II metabolism in marine bivalve mollusk species (Corbicula fluminea) at concentrations as low as 0.1 μg L −1 . An increased level of lipid peroxidation, an indicator of oxidative stress, was reported for two Polychaeta species after 28 days exposure to caffeine at concentration of 0.5 μg L −1 (Pires et al 2016). Very limited information is available regarding the possible effect of caffeine on important ecological endpoints, such as its potential to alter fish behavior.…”

We studied the ecological consequences of widespread caffeine contamination by conducting an experiment focused on changes in the behavioral traits of wild perch (Perca fluviatilis) after waterborne exposure to 10 μg L−1 of caffeine. We monitored fish swimming performance during both light and dark conditions to study the effect of caffeine on fish activity and circadian rhythm, using a novel three-dimensional tracking system that enabled positioning even in complete darkness. All individuals underwent three behavioral trials—before exposure, after 24 h of exposure, and after 5 days of exposure. We did not observe any effect of the given caffeine concentration on fish activity under light or dark conditions. Regardless of caffeine exposure, fish swimming performance was significantly affected by both the light-dark conditions and repeating of behavioral trials. Individuals in both treatments swam significantly more during the light condition and their activity increased with time as follows: before exposure < after 24 h of exposure < after 5 days of exposure. We confirmed that the three-dimensional automated tracking system based on infrared sensors was highly effective for conducting behavioral experiments under completely dark conditions.

“…The toxicological effects of caffeine do not seem to be a threat to the aquatic living organisms for short time exposure [14]. On the other hand, the long-term continuous release of caffeine into the aquatic environment can lead to sublethal effects on the aquatic living organisms such as oxidative stress and lipid peroxidation in Diopatra neapolitana and Arenicola marina [15,16]. Furthermore, the coral bleaching and the inhibitory effects on algae growth could be presented when the contamination level of caffeine is more than 30 mg/L [13].…”

Enhanced Photocatalytic Degradation of Caffeine Using Titanium Dioxide Photocatalyst Immobilized on Circular Glass Sheets under Ultraviolet C Irradiation

et al. 2020

This work presents the development of titanium dioxide (TiO2) film immobilized on circular glass sheets for photocatalytic degradation of caffeine under ultraviolet C (UVC) irradiation. TiO2 was synthesized through the ultrasonic-assisted sol–gel method and immobilized on circular glass sheets by the doctor blade technique. Polyvinylpyrrolidone (PVP) was used to mix with the TiO2 precursor solution to enhance film adhesion on the glass surface. TiO2 film was mainly composed of anatase phase with a small amount of rutile phase. Caffeine removal was found to increase with increasing irradiation time. Caffeine (20 mg/L) in the synthetic wastewater could not be detected after 3 h of UVC irradiation. The reaction rate of caffeine degradation followed the pseudo-first-order model. The concentrated caffeine solutions required a longer irradiation time for degradation. The used TiO2-coated glass sheets could be easily separated from the treated wastewater and reusable. The caffeine removal efficiency of TiO2-coated glass sheets in each cycle maintained a high level (~100%) during fifteen consecutive cycles.

“…This leads to subsequent compensatory responses, that rely on the activation of antioxidant enzymes such as superoxide dismutase (SOD), a catalase (CAT) and glutathione peroxidase (GPx), which are natural scavengers of ROS (Regoli & Giuliani, 2014). If this compensatory response is not su cient to eliminate ROS, a scenario of oxidative stress may be established (Regoli & Giuliani, 2014;Pires et al, 2016). Among the antioxidant enzymatic defensive system, CAT is extremely important since it converts hydrogen peroxide into water, providing effective protection against oxidative damage (Regoli & Principato, 1995;Nunes, 2019).…”

Effect of sublethal concentrations of the antiparasitic ivermectin on the polychaeta species Hediste diversicolor: biochemical and behavioral responses

2021

Pharmaceutical drugs have emerged as major micropollutants in aquatic ecosystems. Their presence has been systematically reported in monitoring survey, and their wide distribution and constant presence in the wild is a direct consequence of their massive use, in both human and veterinary therapeutics. Drugs used to treat parasitic infections in livestock are major contaminants, given the amounts in which they are administered, and reach the aquatic compartment in high amounts, where they may affect non target species. Some of these drugs are prone to nd their nal deposit in sediments of estuarine areas, exerting their toxic effects preferentially at these locations. Sediment dwelling organisms of coastal areas, such as polychaetes, are especially prone to have their major physiological functions compromised. Ivermectin is one of the most used antiparasitic drugs, and its effects are not limited to biochemical traits, but also behavioral features may be compromised considering their neurotoxic actions. Despite these putative effects, little is known about their toxicity on polychaetes. The present study aimed to characterizes the toxicity of realistic levels of ivermectin on the polychaete Nereis diversicolor, in biochemical and behavioral terms. The obtained results showed that low levels of ivermectin are capable of causing signi cant disturbances in mobility and burrowing activity of exposed worms, as well as alterations of metabolic and anti-oxidant defense e cacy of exposed animals, suggesting that its environment presence may mean a major environmental concern.
