“…In another study, the effect of caffeine on the survival, reproduction, and metabolic processes of daphnia (D. magna) was not confirmed in a laboratory ecotoxicity test until 50 ug/L [44]. The combination of some drugs with caffeine also lowered the adverse effects of drugs on R. subcapitata [45]. For this reason, it is possible that not only the combination of metals but also the presence of caffeine can lead to higher toxicity of eluate for yeasts (Table 3).…”

Caffeine is a verified bio-protective substance in the fight against the biodegradation of cellulose materials, but its ecotoxicity in this context has not yet been studied. For this reason, the ecotoxicity of flax-fiber-reinforced epoxy composite with or without caffeine was tested in the present study. Prepared samples of the composite material were tested on freshwater green algal species (Hematococcus pluvialis), yeasts (Saccharomyces cerevisae), and crustacean species (Daphnia magna). Aqueous eluates were prepared from the studied material (with caffeine addition (12%) and without caffeine and pure flax fibers), which were subjected to chemical analysis for the residues of caffeine or metals. The results indicate the presence of caffeine up to 0.001 mg/L. The eluate of the studied material was fully toxic for daphnids and partially for algae and yeasts, but the presence of caffeine did not increase its toxicity statistically significantly, in all cases. The final negative biological effects were probably caused by the mix of heavy metal residues and organic substances based on epoxy resins released directly from the tested composite material.

“…In addition, traditional methods of treating wastewater, such as activated sludge or up-flow anaerobic sludge blanket reactors, are constrained in their capacity to eliminate CIP (Kim et al 2020 ). It has been reported that hospital wastewater may contain as much as 34 g/L of CIP, implying that CIP is a persistent compound with high environmental resilience (Diniz et al 2021 ). Exposure to CIP has been associated with alterations in the antioxidant enzymes of affected organisms (Trombini et al 2021 ).…”

In this comprehensive review article, we delve into the critical intersection of environmental science and materials science. The introduction sets the stage by emphasizing the global water shortage crisis and the dire consequences of untreated effluents on ecosystems and human health. As we progress into the second section, we embark on an intricate exploration of piezoelectric and photocatalytic principles, illuminating their significance in wastewater treatment and sustainable energy production. The heart of our review is dedicated to a detailed analysis of the detrimental impacts of effluents on human health, underscoring the urgency of effective treatment methods. We dissected three key materials in the realm of piezo-photocatalysis: ZnO-based materials, BaTiO3-based materials, and bismuth-doped materials. Each material is scrutinized for its unique properties and applications in the removal of pollutants from wastewater, offering a comprehensive understanding of their potential to address this critical issue. Furthermore, our exploration extends to the realm of hydrogen production, where we discuss various types of hydrogen and the role of piezo-photocatalysis in generating clean and sustainable hydrogen. By illuminating the synergistic potential of these advanced materials and technologies, we pave the way for innovative solutions to the pressing challenges of water pollution and renewable energy production. This review article not only serves as a valuable resource for researchers and scholars in the fields of material science and environmental engineering but also underscores the pivotal role of interdisciplinary approaches in addressing complex global issues.

“…Caffeine (Figure S2) is the most consumed psychotropic agent globally because of its stimulating effect on the central nervous system which causes a temporary reduction in drowsiness 13,14 . Caffeine can be naturally found in coffees, teas, chocolate products, and carbonated drinks 15 , but is also synthetically added to pharmaceutical formulations to improve analgesic and antipyretic actions 16 .…”

Emerging contaminants in supposably potable water supplies are a global and growing concern. Maintaining conventional water treatment approaches to tackle growing contamination levels would mean exponentially increasing treatment costs, with some contaminants circumventing these efforts altogether. New approaches for water treatment are therefore required. Sulfur polymers made by “inverse vulcanization” are a highly promising candidate material for this purpose. In this work, porous sulfur polymers (PSPs) were synthesized from elemental sulfur and 1,3-diisopropenylbenzene, with porosity introduced via salt templating. The result is a material that can strongly absorb and chemically neutralize a model contaminant (caffeine). PSPs show adsorption up to 5 times higher than a leading adsorption material (activated carbon). This is the first-ever report demonstrating sulfur polymers as effective materials for removing emerging contaminants from water. The versatile synthesis of sulfur polymers offers variation, which means that there is much more to explore in this exciting research area.
