“…(11.1-11.5) in every sampling site, exceeding the tolerated levels [23]. The findings showed that the soil moved toward an alkaline state and that it was over the allowable limits of (6)(7)(8)(9). The pH in the effluent is moving toward a higher value, indicating alkalinity conditions, and this could negatively affect the permeability of the soil and the development of the soil microbial flora.…”

“…Azo dye is well known to cause damage to living cells via its mutagenic and carcinogenic potential that can affect the genome of living cells, it also affects the ecosystem and thus puts humanity at risk [5]. There is a continuous search for the best and most environmentally friendly method of cleaning, however, partially degraded dyes are more toxic than the mother molecule [6,7]. This toxic potential of the dye creates a selective pressure on the bacteria population and causes adaptation for survival [8].…”

The global industrialization of chemical dyes used for household products has resulted in various dyes leaching into the soil. Azo dye textile contamination could lead to infertile soil. This study investigates the ecological effect of azo textile dye contamination on bacterial biomass, selective pressure, and associated physicochemical changes in soil samples contaminated with textile azo dye in Itoku, Abeokuta, Nigeria. Microbiological and physicochemical changes of the soil and effluent samples collected were determined using standard procedures. Results revealed that the average count of total viable bacteria in the contaminated sampling sites ranged from 0.82±021 x 106 cfu/g to 1.65±0.02 x 106 cfu/g which was significantly lower than the control bacterial counts. The dye contaminated and the control soil samples each contained a heterogenous population of bacteria which included Paenibacillus validus, Bacillus licheniformis, Bacillus niacin, Seratia liquefaciens, Staphylococcus gallinarum, Bacillus subtilis, and Bacillus coagulans. The physicochemical analysis of the soil revealed high levels of pH in the azo dye contaminated soil (10.4–11.1) and electrical conductivity was also highest in the effluent (1250 to 2943 units) compared to the control (430 to 480). Importantly, the control samples were higher in all of the other tested soil parameters including cation exchange, the mean value of the organic matter, water holding capacity, particle density, moisture content, and total porosity. Conclusion- Azo dye contamination caused decreases in bacterial density and many other soil parameters along with higher PH and electrical conductivity which suggests that azo textile dye contaminated soil is unfavorable for agricultural purposes and potentially toxic to the ecosystem.

“…The annual production of synthetic dyes corresponds to 7 × 10 7 tonnes; the textile industry consumes approximately 10,000 tonnes of these dyes [17], and it is estimated that 280,000 tonnes of dyes are discharged into wastewater each year. For the production of some dyes, it is necessary to use heavy metals, such as mercury, chromium, cadmium, lead, or arsenic [18,19].…”

Conventional dyeing processes currently practiced in the textile industry have a great environmental impact, mainly in relation to the quantity and pollution of water, use of toxic chemicals, atmospheric emissions, and high energy consumption. This study aims to discuss the relationship between the variables that involve conventional dyeing processes and environmental issues. It presents the mapping of the materials and emerging technologies for ecological coloration, specifically for the pretreatment and dyeing stages. Regarding pretreatment, it discusses biochemical (enzymes) and physical treatment (ultraviolet radiation, plasma, and ozone technology) approaches. With respect to the dyeing processes, it addresses ecological materials (natural dyes) and emerging technologies (such as plasma, supercritical CO2, AirDye®, ultrasonic, microwave, Nano-DyeTM, and electrochemical). Given the importance of ecological coloration, this study provides important reflections on the urgency of resolving issues related to barriers and economic viability in the implementation of the alternatives presented and demonstrates the need to develop educational projects to prepare fashion and textile professionals.

“…Industrial organic dyes are some of the main mass water pollutants. It was reported that about 12% of dyes in the manufacturing process and 20% of dyes in the dyeing processes are lost and discharged with effluents [ 1 , 2 ]. These dye impurities have relatively high toxicity, carcinogenicity, and potentially mutagenic properties [ 3 ].…”

Creating stimulus-sensitive smart catalysts capable of decomposing organic dyes with high efficiency is a critical task in ecology. Combining the advantages of photoactive piezoelectric nanomaterials and ferroelectric polymers can effectively solve this problem by collecting mechanical vibrations and light energy. Using the electrospinning method, we synthesized hybrid polymer-inorganic nanocomposite fiber membranes based on polyvinylidene fluoride (PVDF) and bismuth ferrite (BFO). The samples were studied by scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), total transmittance and diffuse reflectance, X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), vibrating-sample magnetometer (VSM), and piezopotential measurements. It has been demonstrated that the addition of BFO leads to an increase in the proportion of the polar phase from 86.5% to 96.1% due to the surface ion–dipole interaction. It is shown that the composite exhibits anisotropy of magnetic properties depending on the orientation of the magnetic field. The results of piezo-photocatalytic experiments showed that under the combined action of ultrasonic treatment and irradiation with both visible and UV light, the reaction rate increased in comparison with photolysis, sonolysis, and piezocatalysis. Moreover, for PVDF/BFO, which does not exhibit photocatalytic activity, under the combined action of light and ultrasound, the reaction rate increases by about 3× under UV irradiation and by about 6× under visible light irradiation. This behavior is explained by the piezoelectric potential and the narrowing of the band gap of the composite due to mechanical stress caused by the ultrasound.
