Abstract—The behavior of many metallic trace metals is often affected by several factors, among them pH which plays a crucial role in the transport, distribution, uptake, solubility, bioavailability and bioaccumulation of ETM in plants from soils as reported by many authors. This study was conducted to elucidate the effect of pH on the toxicity of cadmium on beans (Phaseolus Vulgaris) with the main objective to reveal the response of bean plants at different pH values to different added concentrations of Cd2+. The results revealed that the growth of beans increased with increasing pH. However, the uptake and the accumulation of cadmium decreased. Generally, it appears from the obtained results that the metals tested exert more toxic effect in acidic than in alkaline pH conditions.
Index Terms—pH, solubility, bioavailability, absorption, toxicity.
