“…These spectra present some shifted bands; the band at 3287 cm −1 shifted to 3303 and 3280 cm −1 after Pb(II) and Cu(II) adsorption representative of O–H bond vibrations, 2027 cm −1 alkynes triple bond vibration shifted to 2036 and 2017 cm −1 which maybe a consequence of O–H complexation with the cations, the band at 1644 cm −1 representative for N–H groups shifted to 1635 and 1629 cm −1 , suggesting a complexation with Pb(II) and Cu(II), respectively, the band at 1416 cm −1 (S=O) shifted to 1421 and 1407 cm −1 due to interaction between cation and some functional groups like O–H and N–H. Similar results were presented by Török et al who studied dyes removal from aqueous solution using L. minor .…”

Lead and Copper Adsorption Behaviour by Lemna gibba: Kinetic and Equilibrium StudiesCopper and lead were found in sediments of Chimaliapan Lake in the State of Mexico; these elements may come from local tanneries and other industries. The sorption behaviour of lead and copper by Lemna gibba sampled from the same lake was determined. The results showed that the removal capacity for lead (about 98.9%) was higher than for copper (60%). The maximum adsorption capacities were at pH 4 and highest for Pb(II). Adsorption kinetics showed that the experimental data fitted the pseudo-first and -second order models (R 2 ¼ 0.99). Equilibrium data of Pb(II) fitted best to the Langmuir model and Cu(II) data to the Langmuir and Freundlich models.

“…After purchase, the plants underwent a seven-day acclimatisation period in Hoagland solution to provide all the necessary nutrients [21]. Following this, plants of uniform length and weight (these morphological characteristics were recorded) of both species were put in 1 L of solutions with different dye concentrations (50-500 mg/L).…”

Organic pollutants, such as dyes, have a negative effect on the aqueous environment, therefore, their elimination from water bodies is a high priority. In this work, Eichhornia crassipes and Salvinia natans, both model plants with high phytoremediation efficiency, were exposed to various concentrations (Ci = 50–500 mg/L) of Eriochrome Black T (EBT). Their capacity to assimilate EBT was studied for 16 days of exposure, similar to natural conditions and by spectrophotometric monitoring of the dye concentration (EE. crassipes; 150 mg/L = 33%; ES. natans; 150 mg/L = 71.5%). The changes of the experimental parameters (pH—equalised by day 5, temperature, humidity, light intensity) were followed, and plant growth and biochemical responses to toxic stress effects (photosynthetic pigments, Energy-dispersive X-ray spectroscopy (EDX)—decreased effect of P, Mg, Ca, S and K, Scanning electron microscopy (SEM), defense enzyme) were examined. Furthermore, changes in oxidative- and photo-degradation of EBT in time and the solid-state properties (SEM, EDX, Fourier-transform infrared spectroscopy-FTIR) of the dye were investigated. Our results demonstrate that, despite the toxic stress, both species succeeded in reducing the dye-concentration of the water and S. natans proved to be more efficient in binding and removing organic dyes. With our findings, we proved that both plants alleviated the abiotic stress of dye contamination.

“…The removal of these dyes and their metabolites from fish products has received little consideration in the literature. Previous studies focused on the removal of CV and MG from aqueous solutions using biosorbents (Raval, Shah, & Shah, ), ionic liquids (Lv, Cui, Zou, & Zheng, ), or biological removal (Török et al., ). Other studies showed that CV is able to bind to proteins such as bovine serum albumin (BSA; Qin, Yin, & Shen, ; Xu et al., ) and casein (Santhanalakshmi & Balaji, ).…”

A rapid and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was validated and used to quantify crystal violet (CV), leucocrystal violet (LCV), malachite green (MG), leucomalachite green (LMG), and brilliant green (BG) residues in frozen fish (121 samples) from various countries, in order to detect the use of prohibited antibiotic dyes in fish for human consumption. The microbial quality of the fish was also assessed along with the effectiveness of a simple treatment with whole fat milk to reduce the levels of CV and LCV contamination. CV and LCV were the only two residues detected. They were found in farmed Pangasius (0.362 to 41.34 µg/kg and 0.178 to 10.58 µg/kg, respectively) and Tilapia (1.24 to 9.48 µg/kg and 1.29 to 2.81 µg/kg). Based on aerobic plate count (APC), 74%, 59%, and 55% of the samples of Tilapia fillets (from China) and Pangasius fillets (United Arab Emirates and Vietnam), and 100% and 50% of the skin samples of Hake (Argentina and U.S.A.) were of unacceptable microbial quality (APC > 10 7 cfu/g). Human pathogens, namely Escherichia coli, Staphylococcus aureus, and Vibrio spp., were detected in most fish. A significant reduction in CV and LCV concentrations by more than a third was achieved after immersing Pangasius and Tilapia fillets in whole fat milk for 120 minutes. These findings support the necessity of regular inspections and monitoring of CV and other antibiotic dye residues in fish, along with routine assessments of fish microbial quality, in order to protect public health. Practical Application: The described LC-MS/MS method can be used to rapidly and simultaneously quantify antibiotic dye residues in frozen fish. CV and LCV were detected in farmed Pangasius and Tilapia fillets and their concentrations was reduced by more than one third after immersing the fillets in whole milk for 120 min, a treatment which is not intended to replace safe fish farming practices upstream to artificially lower the level of banned dyes in fish. The findings support the necessity of regular inspections and monitoring of CV and other antibiotic dye residues in fish, along with assessments of fish microbial quality, to protect public health.
