Water pollution caused by industrial effluent discharges has become a worrisome phenomenon due to its impact on environmental health and safety. Textile industries contribute immensely to surface water deterioration and are categorized among the most polluting in all industrial sectors. For this reason, the toxicity of treated textile effluent was assessed in Celossia argentea by exposing them to effluent-polluted surface water from Ibeshe River. In the present study, parameters investigated includes, growth, photosynthetic pigment content, lipid peroxidation, and metal accumulation. The results showed that treated textile effluent from Nichemtex Company, affected the growth, dry biomass, root development and photosynthetic pigment content of C. argentea. The treated effluent caused 41% growth inhibition while the total chlorophyll decreased by 59.87% in relation to the control plants. Furthermore, it also elevated the levels of lipid peroxidation and heavy metals in the plant. It was therefore implicated that treated textile effluent entering Ibeshe River could cause toxic effects on organisms. It was emphasized that using the water for irrigation and as portable water in its present state is unsafe.
