Textile effluent toxicity trend: A scientometric review

Textile production generates high volumes of colored effluents, including several toxic substances potentially dangerous to the environment. It is important to highlight out that decolorization is not the removal of toxicity and currently there is no scientometric perspective addressing about this theme. The present study aimed sci-entometrically review the state-of-art on textile effluent toxicity, presenting scientific trends and gaps, research hotspots and science statistics on this issue, and identifying the directions to guide future efforts. The words textile effluent AND *toxicity* were searched in the Web of Science, between the years 1945 a 2020. 214 articles were retrieved and selected with relevant impact factor (H-index = 45) and were analyzed in CiteSpace, Excel, Statistica and Bibliometrix software. Clearly, greater focus and scientific efforts are urgent to find efficient ways to manage textile wastewater. India, Brazil, and Turkey lead in the publications number on the topic and are also the leading textile producers worldwide. The efforts were focused on the search for efficient effluent treatments promoting decolorization, nontoxic and economically feasible for textile industries. Highlights those 40 years have passed since the first publication and still no efficient and sustainable way of managing this waste is available.

Automated summary

Textile production generates toxic effluents that pose a threat to the environment, and there is a lack of scientific research on their toxicity. This study aims to review the current state-of-art on textile effluent toxicity and identify research gaps and trends. The results show the need for more focused scientific efforts to manage textile wastewater effectively.
