“…Among all industries, tanneries are considered some of the most polluting, and are a major contributor to aquatic contamination [10]. Tannery effluent is extremely hazardous due to high organic loadings, solids, and metals [11], particularly chromium (Cr), a well-known ubiquitous pollutant considered as a great menace to aquatic environments, and ultimately, human beings [12]. The dark colouration and low oxygen content of tannery effluents indicates the strength of pollution, which ultimately affect the survival of aquatic organisms, especially fish, thus having great ecological relevance [5].…”

Aquatic pollution caused by industrial effluents is an environmental issue, imposing deleterious impacts on the overall environment, specifically, on humans, by disrupting the balance of the ecosystem. Among all the industries, tanneries are considered some of the most polluting due to heavy use of toxic organic and inorganic compounds during leather processing, most of which find their way into rivers, lakes, and streams, thus exerting adverse effects on aquatic life, particularly on fish. Considering the huge concentrations of pollutants present in tannery effluents, toxicity evaluation is of prime importance. Therefore, bioassays are usually employed to assess the acute toxicity of industrial effluents and efficiency of effluent clean-up technologies as they provide a thorough response of test species to the substances present in the tested media. In the present study, the toxic effects of tannery effluent on common grass carp (Ctenopharyngodon idella) were studied for 96 h in laboratory conditions. The effluent was added at different concentrations, before and after treatment by constructed wetlands (CWs). During this period, mortality data was collected to calculate the 96 h-LC50 (lethal concentration inducing 50% mortality) and acute toxicity of C. idella. In addition to this, observations on change in morphological, physiological, and behavioural patterns were also made every 24 h. The present toxicity assay revealed that the raw tannery effluent changed the morphology, physiology, and behavioural response of fish. Moreover, fish exposure to raw/untreated effluent caused high acute toxicity and 100% mortality, due to the presence of high concentrations of salts and chromium (Cr) metal. While treatment of tannery effluent by CWs vegetated with different plants (B. mutica, L. fusca, and T. domingensis) significantly reduced its toxicity and fish mortality as well, and inoculation of salt and Cr-tolerant endophytic bacteria (Enterobacter sp. HU38, Microbacterium arborescens HU33, and Pantoea stewartii ASI11) further reduced (up to 90%) its toxicity level. Hence, the use of CWs for tannery effluent treatment can be recommended to favour public health and promote the overall safety of the environment.

“…Hexavalent is considered more toxic because plasma membrane easily permits to pass out through it. Once enters inside the cell, forms major complexes with macromolecules including DNA (Bakshi & Panigrahi, 2018). Both forms of Cr organic and inorganic are significant for humans as well as for animals.…”

In aquaculture industry, the aim of feed formulation is to provide the fish with feasible diet to enhance their body. Carbohydrates supplemented with chromium compounds (organic and in-organic) are major energy currencies for biological machinery of fish. Here, this article presents a description that emphasizes the effect of chromium picolinate (organic) and chromium chloride hexahydrate (in-organic) on growth execution and genotoxicity of Labeorohita. Seven groups (each with a replica) with 30 Labeorohita fingerlings were formed: a control group, three groups were supplemented with chromium chloride Hexahydrate (0.3, 0.5 and 0.6 mg kg−1) and three groups were supplemented with Cr-Pic, 0.3, 0.5 and 0.6 mg kg−1) respectively. The experimental group T4 fortified with (Cr-Pic) along with carbohydrates by dose of 0.3 mg/kg demonstrated significant results (P < 0.05). Superior growth for Labeo rohita was observed as compared to control and other experimental groups. Minimum growth trend was observed in group T5 (CP-0.5 mg/kg), T6 (CP-0.6 mg/kg) and T7 (control) respectively. Comet assay results indicated the dose and Cr related (organic or in-organic) genetic damage in fish erythrocytes. Hence, maximum comet parameters (Tail length, Tail DNA and Olive Tail Moment) were observed in (in-organic Cr) by 0.3 mg/kg concentration. This study suggested the toxicity corresponding to in-organic Cr but organic Cr could be used as growth promoter if so. Overall results demonstrated supplementation of organic chromium compounds by 0.3 mg/kg should be reconsidered for growth. This drive of research address the fish farmers to utilize the feed supplemented with organic Cr compounds which is most appropriate to provide sustainable yield as part of increment in growth performance and beneficial health effects for consumers on indices to reduce the toxicity risks.

“…They are strictly regulated by occupational safety authorities worldwide. The toxicity of Cr(VI) is attributed to its water solubility and permeability through cell membranes [9]. Absorption of water-soluble chromates in the blood is high, whereas insoluble chromates have lower absorption and longer residence time in lungs.…”

Scale-Up of Self-Regenerating Semi-Batch Adsorption Cycles through Concurrent Adsorption and Reduction of Cr(VI) on Sheep Wool

et al. 2020

A previous publication by our group reported that adsorption of Cr(VI) on sheep wool reached 99% when allowed a long residence time, with concurrent reduction to Cr(III). In this study, the process was scaled up by optimizing a pilot plant based on semi-batch adsorption cycles. This yielded Cr(III), which is about 300 times less toxic than Cr(VI), and can be precipitated using lime at high pH. Since the reduction step is slower than the adsorption one, an adsorption column was designed to perform semi-batch operation cycles, whereby the extended “off cycle” allows reduction to take place. Since reduction of Cr(VI) frees active sites on wool, the plant acts in lieu of in situ regeneration, accompanied by additional adsorption of Cr(VI). The results show that 97% of the column efficiency can be recovered within 24 h of “off cycle”. Wastewater from a local electroplating industry was treated by this method with high removal of Cr(VI), reaching the limit permitted by environmental standards. This study also reveals that typical concentrations of heavy metals, present in wastewater produced from electroplating, had no substantial antagonistic interference with Cr(VI) adsorption.
