“…Due to the increasing application rates of isoxaflutole accelerated by the cultivation of isoxaflutole-resistant GM soy, its chemical load on the environment increases, yet environmental accumulation risk has not been attributed to the a.i. In cases of severe environmental pollution with pesticide a.i.s causing persistent or cumulating contamination, not only the environmental fate and toxicology of the substance, but potential means of remediation are needed to be assessed, as seen, e.g., in the case of paraquat [ 40 ] or glyphosate [ 32 , 41 , 42 ]. The environmental status of isoxaflutole is fortunately not as unfavorable, apparently manageable by certain application restrictions, and therefore the feasibility of remediation is uncalled for.…”

The environmental load by isoxaflutole and its formulated herbicide products has increasingly become apparent because, after the ban of atrazine, isoxaflutole has become its replacement active ingredient (a.i.). Obtaining information regarding the fate of this a.i. in environmental matrices and its ecotoxicological effects on aquatic organisms is essential for the risk assessment of the herbicide. In this study, the effects of Merlin Flexx- and Merlin WG75 formulated isoxaflutole-based herbicide products and two selected additives (cyprosulfamide safener and 1,2-benzisothiazol-3(2H)-one antimicrobial agent) were investigated on Raphidocelis subcapitata in growth inhibition assays. In ecotoxicological tests, two conventional (optical density and chlorophyll-a content) and two induced fluorescence-based (Fv*/Fp: efficiency of the photosystem PSII and Rfd* changes in the observed ratio of fluorescence decrease) endpoints were determined by UV-spectrophotometer and by our FluoroMeter Module, respectively. Furthermore, dissipation of isoxaflutole alone and in its formulated products was examined by an HPLC-UV method. In ecotoxicological assays, the fluorescence-based Rfd* was observed as the most sensitive endpoint. In this study, the effects of the safener cyprosulfamide and the antimicrobial agent 1,2-benzisothiazol-3(2H)-one on R. subcapitata is firstly reported. The results indicated that the isoxaflutole-equivalent toxicity of the mixture of the isoxaflutole–safener–antimicrobial agent triggered lower toxicity (EC50 = 2.81 ± 0.22 mg/L) compared to the individual effect of the a.i. (EC50 = 0.02 ± 0.00 mg/L). The Merlin Flexx formulation (EC50 = 27.04 ± 1.41 mg/L) was found to be approximately 50-fold less toxic than Merlin WG75, which can be explained by the different chemical characteristics and quantity of additives in them. The additives influenced the dissipation of the a.i. in Z8 medium, as the DT50 value decreased by approximately 1.2- and 3.5-fold under light and dark conditions, respectively.

“…[25] Adsorption has been regarded as one of the most effective methods for removing dyes because of its straightforward design, high efficacy, ease of handling, and low cost. [26][27][28][29] In the literature, it is possible to find several studies that synthesize adsorbents from residues for dye removal, such as phaseolus vulgaris L. for the removal of reactive red 198 dye, [30] coir pith, sawdust, and sugarcane fibre for the removal of crystal violet and rhodamine B, [31] sesame hull (Sesamum indicum L.) for the removal of methylene blue (MB), [32] soybean hull for the removal of safranin dye, [33] Musa acuminata and Solanum tuberosum peels for emerald green dye removal, [34] Bengal gram bean husk for removing MB and methylene orange (MO), [35] Citrullus Lanatus peels for removing acidic dyes, [36] pecan pericarp (Carya illinoensis) for removing methyl violet 2B, [37] and a pod of forest species [38,39] and tree bark [40,41] in the removal of cationic dyes, among others.…”

This study analyzed the viability of using malacoculture residue (Mytella falcata) to produce layered double hydroxides (LDHs) and for its subsequent use as an adsorbent. The CaAl/LDH‐RE material was produced with calcium oxide from the residue and the CaAl/LDH‐AP was produced with a commercial reagent. Both were used to remove methyl orange (MO) and methylene blue (MB) dyes. The CaAl/LDH‐RE presented a surface area of 28.54 m2 g−1, being 65.62% larger than the CaAl/LDH‐AP material (17.23 m2 g−1). The adsorbents showed mesopores distributed on a surface formed by plates in the form of hexagonal sheets arranged in an overlapping manner. The dosage of 0.05 g L−1 obtained the removal of 95% and 97% for MO, while for MB it was 94% and 93% using the adsorbents LDH/CaAl‐AP and LDH/CaAl‐RE, respectively. The system reached equilibrium at 90 min for MO and 120 min for MB. The pseudo‐second order model well represented the kinetic data reaching 11.36 mg g−1 (CaAl/LDH‐RE) and 8.42 mg g−1 (CaAl/LDH‐AP) for MO, and 4.47 mg g−1 (CaAl/LDH‐RE) and 4.14 mg g−1 (CaAl/LDH‐AP) for MB. The Freundlich model better represented the isothermal data, where the temperature exerted little influence. Adsorbents showed similar removal percentages in real and synthetic matrices. The LDH/CaAl‐RE can be applied in up to 3 cycles, maintaining its adsorption capacity. These results corroborate the use of MFW to produce CaAl/LDH‐RE, which can be used for the efficient removal of organic pollutants in an aqueous solution.
