“…This ecotoxicity study was carried out with the intention of knowing the efficiency of the adsorption to remove bentazone from the effluent, highlighting, once again, that this onion biomodel is highly sensitive to xenobiotics, even in concentrations on the ng L −1 scale 44 . After subjecting the bentazone solution to adsorption, root growth and cell cycle obtained for onion bulbs were similar to the control with distilled water [Table 5; Fig.…”

BACKGROUNDThis study aimed to produce activated carbon from spent coffee (Coffea arabica) grounds by chemical activation using zinc chloride and nitric acid to remove bentazone from aqueous solutions.RESULTSThe fresh spent coffee grounds were characterized by Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and the activated carbon by X‐ray Diffraction (XRD), Infrared Spectroscopy (FT‐IR), Brunauer–Emmett– Teller (BET), point of zero charge, scanning electron microscopy (SEM), and Boehman method. Adsorption experiments were carried out in a batch system. The results showed a 70% efficiency in bentazone removal using ZnCl2 carbon. Kinetic studies indicate that the adsorption rate increased slowly up to 720 min; the first‐ and second‐order models fit the experimental data at a concentration of 50 mg.L−1. The adsorption equilibrium is represented by the Langmuir model with a high adsorption capacity of 279.33 ± 6.29 mg.mg−1. The adsorption efficiency was also confirmed by the toxicity analysis of the effluent with bentazone at 50 mg.L−1, using the A. cepa bioassay, a high‐sensitivity test for pollutants in water.CONCLUSIONBefore adsorption, the effluent caused significant cytogenotoxicity to onion root meristems. After adsorption, the generated effluent no longer caused toxicity to the test system, and the results obtained were similar to the control with distilled water.This article is protected by copyright.

“…Several recent studies, including ours, have shown that, for various reasons, octocrylene is harmful to health and the environment. − ,,− It seems that many cosmetic companies are now formulating their products without octocrylene for the benefit of their customers and the preservation of coral reefs. The proven impact of octocrylene on a second coral species S. pistillata suggests that potential environmental pollution with octocrylene can impact many reef-building species.…”

The objective of this work was to study the effect of octocrylene on Stylophora pistillata and to compare the metabolomic response of this coral species to that obtained with Pocillopora damicornis. When S. pistillata coral was exposed to octocrylene, it accumulated octocrylene derivatives similar to P. damicornis. Octocrylene−fatty acid conjugates were found, as well as octocrylene heterosides. Furthermore, the tissue concentrations of various acylcarnitines and three sphingoid bases increased significantly. This phenomenon was indicative of mitochondrial dysfunction and the induction of cellular senescence processes in exposed corals. Overall, the responses of the two corals to octocrylene pollution were consistent. The proven impact of octocrylene on a second coral species suggests that potential environmental octocrylene pollution could impact many reef-building species. Furthermore, this work demonstrates that octocrylene may be modified in vivo by many organisms and that levels of octocrylene contamination in the food chain have probably been underestimated until now.

“…Octocrylene is the most used sunscreen worldwide in cosmetics and pharmaceutical products due to its high efficiency in protecting against ultraviolet rays and because it is a stabilizer of other solar filters, such as benzophenone-3, methoxydibenzoylmethane, and avobenzone [1,2]. This filter is a cinnamate ester, with a molecular weight of 361.49 g•mol −1 , octanol-water partition coefficient of 6.88, low solubility in water, high resistance to photodegradation, and high lipophilicity [3,4].…”

The emerging pollutant octocrylene is not efficiently removed from effluents by conventional treatment and is recurrently found in rivers. This study evaluated the adsorption of octocrylene using commercial carbon and biochar from spent coffee grounds activated with ZnCl2. The two adsorbents had an efficiency of approximately 100% in pollutant removal throughout the experimental design. The kinetics and equilibrium isotherms showed a good correlation with the experimental data. The kinetics showed adsorption of the contaminant in 40 min for both adsorbents. The model equilibrium isotherms with the best fit and adsorption capacity was Langmuir for biochar, with a capacity of 37.822 ± 0.005 µg∙mg−1 compared to 33.602 ± 0.202 µg∙mg−1 for commercial carbon. Furthermore, a toxicity analysis of a 600 µg∙L−1 octocrylene solution was carried out before and after adsorption with the two charcoals separately, using Allium cepa roots. Before adsorption, the solution was phytotoxic and cytogenotoxic. After adsorption, the solution obtained for each charcoal no longer caused toxicity to the roots. The charcoals tested had high removal efficiency and adsorption capacity, a condition reiterated by the toxicity results. However, biochar better represented the Langmuir model in the adsorption process when removing octocrylene from the aqueous medium.
