Responses of Amaranthus hybridus to effluent from an aluminum plating industry in Lagos, Nigeria
Abstract The study investigated the responses of Amaranthus hybridus to effluent from an aluminum plating plant in Lagos, Nigeria. Seedlings were raised from seeds and were grouped into three categories, each representing a treatment. The first group which is the control received 250 ml of water via the roots every 3 days, the second category received half-strength effluent via the roots every 3 days, while the third group received full-strength effluent via the roots every 3 days throughout the study period. Physiological and biochemical, as well as metabolic, parameters representative of oxidative damage and antioxidant activity were evaluated after the treatments. The physicochemical analysis of the effluent showed that total suspended solids, Al and Zn levels were higher than the recommended standards. The biomass and the protein content of the control were 18.01 g and 0.835 mg/g dry wt, respectively, as against 12.04 g and 0.368 mg/g dry wt observed in the treated plants. In contrast, effluent treatment caused a significant increase in malondialdehyde level as well as activities of antioxidant enzymes. The present study revealed that the effluent adversely affected growth and development of A. hybridus. Continual discharge of these industrial effluents could have a negative impact on the environment especially to fragile ecosystems.
