“…During textile processing, inefficiencies in dyeing result in large amounts of the dyestuffs being directly lost to the wastewater [3][4][5]. These compounds can be released into surface waters or enter terrestrial systems when sewage effluent is employed for irrigation or where sewage sludge is applied as a fertilizer to agricultural lands [26]. Thus, considering this fact, the present study investigated the ecotoxicity of two textile dyes, DB38 and RB15, on non-target organisms (terrestrial and aquatic) of different trophic levels.…”

“…According to Pereira et al [26], Indigo Carmin, a textile dye, only induced significant mortality of E. andrei after 72 h of exposure and at high concentrations, with a LC 50 72 h of 75.70 mg/cm 2 . As in the present study, due to the low mortality rates presented after 24 h and 48 h of exposure, it was not possible to estimate the LC 50 for DB38 and RB15 dyes under the conditions tested.…”

“…As previously mentioned, the majority of the toxicological studies concerning textile dyes are carried out with aquatic organisms. However, several assays can also be carried out with terrestrial organisms in order to understand their impacts on the edaphic environment [26]. In this study, E. foetida was used as a model terrestrial organism to measure the acute toxicity of DB38 and RB15 dyes using the filter paper contact test.…”

“…Although the importance of soil macrofauna in the balance of ecosystems and in environmental monitoring is known, few studies are available regarding the toxicity of dyes for these organisms. When exposed to contaminated environments, earthworms may alter their ecological interactions, as well as their survival and reproduction [26].…”

Thus the acute earthworm toxicity test using Eisenia foetida or Eisenia andrei has been recommended for detecting potential soil toxicants by both regulatory agencies and environmental monitoring programs [26].…”

The textile dyeing industry is one of the main sectors contributing to environmental pollution, due to the generation of large amounts of wastewater loaded with dyes (ca. 2-50% of the initial amount of dyes used in the dye baths is lost), causing severe impacts on human health and the environment. In this context, an ecotoxicity testing battery was used to assess the acute toxicity and genotoxicity of the textile dyes Direct Black 38 (DB38; azo dye) and Reactive Blue 15 (RB15; copper phthalocyanine dye) on different trophic levels. Thus these dyes were tested using the following assays: Filter paper contact test with earthworms (Eisenia foetida); seed germination and root elongation toxicity test (Cucumis sativus, Lactuca sativa and Lycopersicon esculentum); acute immobilization test (Daphnia magna and Artemia salina); and the Comet assay with the rainbow trout gonad-2 cell fish line (RTG-2) and D. magna. Neither phytotoxicity nor significant effects on the survival of E. foetida were observed after exposure to DB38 and RB15. Both dyes were classified as relatively non-toxic to D. magna (LC > 100 mg/L), but DB38 was moderately toxic to A. salina with a LC of 20.7 mg/L. DB38 and RB15 induced significant effects on the DNA of D. magna but only DB38 caused direct (alkaline comet assay) and oxidative (hOGG1-modified alkaline comet assay) damage to RTG-2 cells in hormetic responses. Therefore, the present results emphasize that a test battery approach of bioassays representing multiple trophic levels is fundamental in predicting the toxicity of textile dyes, aside from providing the information required to define their safe levels for living organisms in the environment.

The global manufacturing sector heavily relies on the textile industry, yet the widespread utilization of synthetic dyes within this sector has raised serious environmental apprehensions, notably regarding wastewater contamination. The release of untreated wastewater containing residual dyes poses a significant risk to both aquatic ecosystems and human well‐being. In reaction to this issue, considerable efforts have been made to develop efficient and sustainable methods for the removal of textile dyes from wastewater. This comprehensive review paper furnishes in‐depth literature information covering various aspects of dyes, including their classification, toxicity effects, and evaluation of recent advancements in dye removal technology, emphasizing their advantages, limitations, and future potential. Various strategies are covered, including physical, chemical, and biological methods. Physical techniques like adsorption, filtration, and membrane technologies are contrasted with chemical approaches such as coagulation, precipitation, and advanced oxidation processes. Biological methods include the utilization of micro‐organisms, fungi, and enzymes to break down or metabolize dye compounds. Key considerations in the critical analysis include the efficiency, cost‐effectiveness, and scalability of each method. This review focuses on enzyme breakdown (biological) and adsorption (physical) color removal procedures, which are currently considered the most effective. It also proposes the utilization of a composite adsorbent, anticipating enhanced efficiency and faster removal of dyes through this technique.
