TL;DR: In this paper, a study was conducted to determine physiochemical and bacteriological properties of seawater and sediments from the coast of Tunisia during six successive months, where enterococcus faecalis was detected in all the sites indicating a human fecal contamination and all the isolates were highly resistant to rifampicin, gentamicin, chloramphenicol, ampicillin, and azithromycin.
Abstract: The aim of this study is to determine physiochemical and bacteriological properties of seawater and sediments from the coast of Tunisia during six successive months. The conductivity was measured using previously calibrated Hach Conductivity meter. Total suspended solid was determined using Whatman GF/C glass fiber filter (Sigma Aldrich), and the turbidity was assessed using a spectrophotometer (UV/Vis). The pH was measured using pH electrodes. Other physiochemical parameters were determined using Pastel UV multiparameter water analyzer (Secomam, aqualabo). Bacterial analysis was displayed by membrane filtration method, and isolates were identified to the species level by Api strips. Susceptibility to antibiotics was determined by disk diffusion methods. Total suspended solid, turbidity, adsorbable organic halogen, chemical oxygen demand, and biochemical oxygen demand were higher than accepted norms in Tunisia. Enterococcus faecalis was detected in all the sites indicating a human fecal contamination, and all the isolates were highly resistant to rifampicin, gentamicin, chloramphenicol, ampicillin, and azithromycin. The situation in Mahdia coast is alarming particularly with the isolation of multidrug resistance strains. It is recommended that the local government provide restrict policies for the treatment and the assessment of municipal wastewater before its discharge into sea. PRACTITIONER POINTS: Coastal Surveillance and Water Quality monitoring in the Rejiche Sea - Tunisia is crucial. Enterococcus faecalis was detected in sea water and sediment samples in the coast of Rejiche. Isolated strains were highly resistant to rifampicin, gentamicin, chloramphenicol, ampicillin and azithromycin.

TL;DR: In this article, the toxicity profile of 90-day oral administration of textile dyeing effluent (TDE) on oxidative stress status and histological changes of male mice was evaluated using analytical approaches and concluded that TDE may involve induction of oxidative stress which ensues in pathological lesions in several vital organs suggesting its high toxicity.
Abstract: Although it is known that textile wastewater contains highly toxic contaminants whose effects in humans represent public health problems in several countries, studies involving mammal species are scarce. This study was aimed to evaluate the toxicity profile of 90-days oral administration of textile dyeing effluent (TDE) on oxidative stress status and histological changes of male mice. The TDE was collected from the textile plant of Monastir, Tunisia and evaluated for the metals, aromatic amines, and textile dyes using analytical approaches. Metal analysis by ICP-MS showed that the tested TDE exhibited very high levels of Cr, As, and Sr, which exceeded the wastewater emission limits prescribed by WHO and Tunisian authority. The screening of TDE through UPLC-MS/MS confirmed the presence of two textile dyes: a triphenylmethane dye (Crystal violet) and a disperse azo dye (Disperse yellow 3). Exposure to TDE significantly altered the malondialdehyde (MDA), Conjugated dienes (CDs), Sulfhydryl proteins (SHP) and catalase levels in the hepatic and renal tissues. Furthermore, histopathology observation showed that hepatocellular and renal lesions were induced by TDE exposure. The present study concluded that TDE may involve induction of oxidative stress which ensues in pathological lesions in several vital organs suggesting its high toxicity. Metals and textile dyes may be associated with the observed toxicological effects of the TDE. These pollutants, which may have seeped into surrounding rivers in Monastir city, can cause severe health malaise in wildlife and humans.

TL;DR: In this paper , the authors used Canthium coromandelicum leaves to synthesize the copper oxide nanoparticles (CuONPs) in a cost-effective, easy, and sustainable approach.
Abstract: The present study focused to synthesize the copper oxide nanoparticles (CuONPs) using novel Canthium coromandelicum leaves in a cost-effective, easy, and sustainable approach. The obtained Canthium coromandelicum-copper oxide nanoparticles (CC-CuONPs) were characterized using UV-Visible spectroscopy, FT-IR analysis, FESEM, HR-TEM imaging, and XRD study. The XRD pattern verified the development of crystalline CC-CuONPs with an average size of 33 nm. The biosynthesized CC-CuONPs were roughly spherical, according to HR-TEM and FESEM analyses. FT-IR research verified the existence of functional groups involved in CC-CuONPs production. Cu and O2 have high-energy signals of 78.32% and 12.78%, respectively, according to data from EDX. The photocatalytic evaluation showed that synthesized CC-CuONPs have the efficiency of degrading methylene blue (MB) and methyl orange (MO) by 91.32%, 89.35% respectively. The findings showed that biosynthesized CC-CuONPs might effectively remove contaminants in an environmentally acceptable manner.

TL;DR: In this paper , a multi-criteria decision-making framework for sustainable supplier selection in the textile dyeing industry, one of Bangladesh's largest chemical consuming industries, was developed.
Abstract: It is important to implement sustainability throughout the supply chain and manufacturing process in order to achieve sustainability in a manufacturing system. As part of that effort, selecting an appropriate supplier while taking sustainability into account is a critical requirement in today's manufacturing industry, particularly in emerging economies like Bangladesh. This requirement is even more critical for any industry that utilizes a variety of chemicals in its manufacturing process. This research attempted to develop a multi criteria decision making (MCDM) framework for sustainable supplier selection in the textile dyeing industry, one of Bangladesh's largest chemical-consuming industries. An extensive literature review and expert feedback have identified 15 critical economic, environmental, and social evaluation criteria for sustainable supplier selection. The weights of the identified evaluation criteria were determined using the Stepwise Weight Assessment Ratio Analysis (SWARA) method. Following that, the Weighted Aggregated Sum Product Assessment (WASPAS) method was used to determine the final ranking of suppliers in the textile dyeing sector using the SWARA method's criteria weights. According to SWARA's findings, the most important criterion is "chemical quality," followed by "price of chemical," "meeting delivery time," "employee health and safety," and "environmental management system." The WASPAS method indicates that supplier A, a global chemical supplier based in Singapore, is the most sustainable of all the competing suppliers. Later in this study, a sensitivity analysis was conducted for WASPAS method for various values of (λ) and later comparing its results with various popular MCDM methods. Sensitivity analysis ensures that the results obtained from WASPAS is in fact valid. This study is expected to assist decision-makers in the textile dyeing industries of emerging economies to efficiently select suppliers who are not only economically viable but also environmentally sustainable in the long run.

TL;DR: In this paper , the authors evaluated the efficiency of implementing the EC process in the treatment of synthetic textile effluents for removing azo dye, in relation to COD, TOC, true color and acute toxicity.
Abstract: Effluents generated by the textile industry can cause serious damage to receiving bodies of water, if not adequately treated. In this context, new treatment methods have been investigated, with great emphasis on electrocoagulation (EC). For this reason, the main objective of this research was to evaluate the efficiency of implementing the EC process in the treatment of synthetic textile effluents for removing azo dye, in relation to COD, TOC, true color and acute toxicity. Experimental tests were performed for the EC process to investigate the effects of current intensity (2 and 4 A), electrolyte concentration (2 and 4 g L-1) and dye concentration (0.05 e 0.10 g L-1) regarding the removal of the dye into the synthetic textile wastewater considering a 20-minute electrolysis time. The results of the EC process revealed the potential for the application of this technology in this type of treatment. Considering that the values found indicate color removal, TOC, and COD in the order of 96.5%, 93.5% and 85.0%, respectively, with a 4A current intensity applied. Still, acute toxicity tests with the bioindicator Daphnia magna showed high toxicity rates (EC50%), with amounts between 5.87% for synthetic textile effluent in the presence of azo dye and 40.24% in relation to treatment via EC. For these test bodies, a negative impact was observed in relation to the presence of azo dye in the synthetic textile effluent on the toxic effects observed, with high immobility/mortality in relation to textile effluent treated by the electrocoagulation process.
