“…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.…”

“…Calculation of the average root length (CMR), preparation of the roots and mounting of slides, calculation of the mitotic index (MI) and cellular alteration index (CAI) Potential for phytotoxicity, cytotoxicity and genotoxicity of the bentazone solution before and after adsorption were evaluated according to the Fiskejo protocol, 43 with modifications from Filipi et al 44 In order to analyze the phytotoxic potential, the length of 10 roots of each bulb was measured with a digital caliper to determine the average root length of each treatment (CMR), according to Eqn (11). As a complement to the analysis of phytotoxic potential, the presence of hook-shaped roots and changes in the thickness and color of the roots were regarded.…”

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.
