Abstract

The effects of pretanning effluent obtained from leather processing on the germination and seedling growth of rice were investigated. Undiluted pretanning effluents, and its 1:10, 1:40 and 1:80 dilutions along with tap water were used for irrigation to germinate the seeds. Some morphological characteristics were investigated. No germination occurred in the seeds irrigated with the undiluted pretanning effluent. Elemental analyses of the shoots and roots of rice seedlings were conducted. The lowest contents of C (29.7%), S (0.41%), Cr (1.2 mg/kg) and Na (2933.8 mg/kg) in shoots were detected in control group. The lowest contents of Cu (38.81 mg/kg) and Mn (2225.0 mg/kg) in roots were determined in irrigations with 1:10 dilutions.
