Bioassay Toxicity Assessment of Remazol Brilliant Blue and Aniline Purple Textile Dyes Contaminated Water Using Zea mays and Sorghum bicolor
Asian Journal of Biotechnology and Genetic Engineering,
The bioassay evaluation of the toxic textile dyes contaminated water has become highly essential due to indiscriminate discharge of wastewater from the local textile dyes factories in Nigeria and also around the world. Textile dyes wastewater has a reasonable amount of organic and inorganic substances, in many cases high load of heavy metals. In this study, the Remazol brilliant blue (RBB) and Aniline purple (AP) textile dyes contaminated water recorded high biochemical oxygen demand (BOD) and chemical oxygen demand (COD) values above the standard requirement of wastewater discharge. Germination percentage of Zea mays and Sorghum bicolor seeds decreases with increasing concentration of Remazol brilliant blue and Aniline purple textile dyes water. Sorghum bicolor seeds have shown to be more sensitive to the different types and various concentrations of textile dyes compared to Zea mays. About 90 and 95% of Sorghum bicolor seeds did not germinate in the different types of textile dyes at various concentrations. Lack of further development of germinated seeds to a distinct root and shoot was also observed in Sorghum bicolor compared with the Zea mays germinated seeds.
- Zea mays
- root length
- Remazol brilliant blue
