concentration of different heavy metals found in the paper mill effluent was ≤ 0.2 ppm [16]. The paper mill effluent was diluted with tap water to obtain different concentrations (5, 10, 20, and 40%) for further use. The tap water was used as a control (0% effluent) that did not contain any detectable heavy metals included in this study.
