“…For such studies, fishes are used as the endpoint of the food chain, because of their capacity of bioaccumulation of toxicants not only from water but also from the available food 13 . Clarias gariepinus was taken as an indicator organism of Orontes River to point out the deteriorated quality of river water along with bioaccumulation, oxidative stress, and DNA damage 14 . Maurya et al 15 took several fishes like Cirrhinus mrigala, Cirrhinus reba, Catla catla, Labeo rohita, and Crossocheilus latius to check the pollution status of the Ganga River basin and bioaccumulation of Cr, Cd, Zn, Cu, and Pb.…”

This study investigated the effect of heavy metals on Labeo rohita inhabiting the Yamuna River, India. Levels of heavy metals measured in the water were as follows: Fe>Mn>Zn>Cu>Ni>Cr>Cd. Gill and liver tissue of exposed L. rohita showed a high metal pollution index, compared to reference fish collected from the Agra Canal. In the exposed fish, higher levels of creatinine and enzyme activity (alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase) were observed, while the A:G index declined. Additionally, higher TLC, lymphocytes, respiratory burst, and nitric oxide synthase activity indicated a heightened immune response. Levels of superoxide dismutase and lipid peroxidation were elevated, while catalase, glutathione S transferase, and glutathione was reduced. DNA of the exposed fish appeared deteriorated, with a greater mean tail length in comparison to the reference. Our results imply that Yamuna River water generates oxidative stress and DNA damage in L. rohita. As this river is a critical source of water and food to the native community, this could pose a threat to public health similar to that in the indicator organism.

“…Particularly, contamination of water by heavy metals is worrisome because of their persistence and the possibilities of bioaccumulation and biomagnification [ 6 , 7 ]. These non-degradable and potentially toxic contaminants include arsenic, chromium, lead, cadmium, mercury, copper, and zinc, among others [ 8 , 9 ].…”

Chemical Modification of Agro-Industrial Waste-Based Bioadsorbents for Enhanced Removal of Zn(II) Ions from Aqueous Solutions

Contamination of water by heavy metals is a major environmental concern due to the potential ecological impact on human health and aquatic ecosystems. In this work, we studied the chemical modification of various fruit peels such as banana (BP), granadilla (GP), and orange ones (OP) in order to obtain novel bio-adsorbents to improve the removal of Zn(II) ions from 50 mg·L−1 synthetic aqueous solutions. For this purpose, sodium hydroxide and calcium acetate were employed to modify the fruit peels. The moisture, extractives, lignin, hemicellulose, and cellulose contents of the raw materials were determined according to ASTM standards. The obtained bio-adsorbents were characterized by scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and thermogravimetric analysis (TGA). The results showed the OP bio-adsorbents performed better, especially when the concentration of the modifier solutions increased, e.g., the OP particles modified using 0.8 M NaOH and Ca(CH3COO)2 solutions resulted in 97% removal of Zn(II) contaminating ions and reached a maximum adsorption capacity of 27.5 mg Zn per gram of bio-adsorbent. The adsorption processes were found to follow a pseudo-second order model. The error function sum of square error indicated the Freundlich isotherm (non-linear regression) as best fit model. The obtained results are particularly interesting for material selection in wastewater treatment technologies based on contaminant adsorption.

“…However, SOD and CAT had the same trend in both species, and in many other studies, an increase in these enzymes with HMS exposure has been observed (Eyckmans et al, 2011; Javed et al, 2015, 2017). But other studies have reported unlike results (Javed et al, 2016; Turan et al, 2020). It seems that many factors, such as species, exposure period, kind of tissue, heavy metal contents, etc., can influence the SOD and CAT activities.…”

Ethylenediaminetetraacetic acid (EDTA) is one of the most popular chelating agents. This study was conducted to investigate the effect of EDTA on the growth and health physiology of beluga (38.47 ± 0.58 g) before and after heavy metal stress (HMS). Five experimental diets, including control, 0.5EDTA, 1EDTA, 1.5EDTA and 2EDTA, were formulated to feed fish for eight weeks. The results showed that fish was fed with dietary 1.5EDTA (108.37 g) had a higher weight gain as compared with control (p < 0.05). Blood performance in the control group after HMS decreased but not in fish fed supplemented diets with EDTA. EDTA reduced uric acid and creatinine levels in beluga. Fish fed dietary 1.5EDTA had a higher value of blood performance (55.17), glucose (50.3 mg/dl), superoxide dismutase (SOD U/ml) (75.8) and glutathione peroxidase (234.0 U/ml) after HMS as compared with the control. Additionally, lower values of uric acid (3.05 mg/dl), creatinine (0.27 mg/dl) and AST (61.47 U/ml) after HMS in the 1.5EDTA group were observed (p < 0.05). Correlation analysis revealed a strong positive correlation between EDTA level and protein efficiency, lipid efficiency, and blood performance and a strong negative correlation with some parameters after stress, including SOD, glucose, uric acid, creatinine and aspartate transaminase (p < 0.01). In conclusion, feeding fish with the 1.5EDTA diet improved growth and detoxified heavy metals.
