“…Among various semiconductor nanoparticles, TiO 2 , CdS, and ZnS hold significance due to their potential applications across diverse fields such as catalysis, biomedicine, sensors, and electrical and electronics industries [19][20][21] . The photocatalytic efficacy of these nanoparticles under visible light primarily hinges on factors such as their band gap, electron-hole recombination rate, specific surface area, and crystalline structure 22,23 . Therefore, the pursuit of creating a cost-effective and highly efficient photocatalyst remains a promising endeavor, both from fundamental research and industrial perspectives.…”

Today, environmental pollution stemming from organic pollutants poses a significant challenge. Various categories of organic compounds, including dyes, pharmaceuticals, aromatics, volatile organic compounds, and more, contribute to contamination of water, soil, and air. The presence of these organics in water not only harms aquatic life but also poses health risks to humans. Thus, it is imperative to eliminate these organic pollutants from the environment. Different methods, such as absorption, adsorption, filtration, biodegradation, chlorination, ozonation have been developed to remove organics from waste water. Photodegradation is one of the important methods to remove organic compounds from aqueous media. Different catalysts have been used by different researchers for photocatalytic degradation of organics. Uses of nanomaterials as photocatalysts have been seen to be a potential approach of remediation of toxic organic compounds from environment. In this approach heterogeneous catalysts using semiconductor nanomaterials have shown to be good photocatalysts. These catalysts have been discovered to exhibit greater efficacy in advanced oxidation processes for eliminating organic contaminants from wastewater. Way of improving photodegradation efficiencies was also discussed. Metal and non-metal doping to regular materials has been seen to be a good approach of enhancing degradation efficiencies of normal photocatalysts. This discussion delves into the sources of these organic compounds, their detrimental effects on the environment, and a comprehensive exploration of conventional degradation methods available for combating these compounds.

“…On 23 October 2000, the European Parliament and Council adopted the EU Water Framework Directive (WFD-2000/60/EC), establishing a community action in water policy. In this context, at the beginning of 2022 (19 January), the EU Commission updated the "watch list" for emerging water pollutants [1][2][3][4]. The study of emerging contaminants, including pharmaceutical compounds, has become one of the biggest concerns in current environmental research.…”

Photocatalysis is an advanced oxidation process that is an environmentally friendly option and one of the most critical technologies in green chemistry today. This work studied the upscaling of photocatalysis as a suitable process for wastewater treatment to remove emerging pollutants. For this purpose, unsupported and supported TiO2 photocatalysts were tested in the photodegradation of ciprofloxacin as a model molecule of an emerging wastewater component, using visible, UV radiation, and solar light. The suitability of TiO2 as a photocatalyst to decompose ciprofloxacin was confirmed in batch photoreactor under Visible and UV radiation, with degradation rates up to 90% after 30 min of irradiation and low adsorption values. TiO2 as a photocatalyst coated in glass support material at the packed bed photoreactor showed good photoactivity for emergent contaminants degradation (95%) under solar radiation. It has been possible to verify that the photocatalytic reactor system constitutes a viable process for eliminating emerging contaminants through environmentally sustainable treatments. Our results corroborate the possibility of degrading emerging contaminants by solar radiation using a packed bed photoreactor, providing a more effective option from a practical and economical point of view for wastewater effluent treatments.

“…These include phthalates, and the bisphenol and phenol groups. However, many other compounds are considered potential EDs including antioxidants, pesticides, biocides, detergents, metals, plasticizers, and organometallic compounds (Mukherjee et al, 2021;Wiesinger et al, 2021;Imparato et al, 2022). Diet is an important exposure route for these known or potential EDs, which enter the food chain in different ways.…”

Introduction: Many natural or synthetic compounds used in foods, dietary supplements, and food contact materials (FCMs) are suspected endocrine disruptors (EDs). Currently, scientific evidence to predict the impacts on biological systems of ED mixtures is lacking. In this study, three classes of substances were considered: i) phytoestrogens, ii) plant protection products (PPP) and iii) substances related to FCMs. Fourteen compounds were selected based on their potential endocrine activity and their presence in food and FCMs.Methods: These compounds were evaluated using an in vitro gene expression assay, the ERα-CALUX, to characterize their responses on the estrogen receptor alpha. Cells were exposed to fixed ratio mixtures and non-equipotent mixtures of full and partial agonists. The concentration-response curves measured for the three classes of compounds were characterized by variable geometric parameters in terms of maximum response (efficacy), sensitivity (slope) and potency (median effective concentration EC50). To account for these variations, a generic response addition (GRA) model was derived from mass action kinetics.Results: Although GRA does not allow us to clearly separate the concentration addition (CA) and independent action (IA) models, it was possible to determine in a statistically robust way whether the combined action of the chemicals in the mixture acted by interaction (synergy and antagonism) or by additive behavior. This distinction is crucial for assessing the risks associated with exposure to xenoestrogens. A benchmark dose approach was used to compare the response of phytoestrogen blends in the presence and absence of the hormone estradiol (E2). At the same time, 12 mixtures of 2–5 constituents including phytoestrogens, phthalates and PPPs in proportions close to those found in food products were tested. In 95% of cases, the response pattern observed showed a joint and independent effect of the chemicals on ER.Discussion: Overall, these results validate a risk assessment approach based on an additive effects model modulated by intrinsic toxicity factors. Here, the CA and IA approaches cannot be distinguished solely based on the shape of the concentration response curves. However, the optimized GRA model is more robust than CA when the efficacy, potency, and sensitivity of individual chemical agonists show large variations.
