| Abstract | Cadmium is one of the most toxic heavy metals found in food and poses a substantial danger to human health, including carcinogenic consequences. This might be utilized as a bio-indicator for cadmium bioaccumulation in plants. Using cadmium-contaminated water for vegetable growing has been linked to increased health risks. Also, pH affects cadmium solubility and plant absorption. It is unknown about risk of cadmium concentrations in agricultural water resources (e.g., rivers, lakes, effluents, etc.) and the health risk of eating vegetables produced in cadmium polluted water affected by pH levels. In this study, hydroponically grown pak choi was utilized to assess cadmium bioaccumulation and health risks. The experiment used four initial cadmium doses (0 mg/L, 1 mg/L, 2 mg/L, and 3 mg/L) over four weeks. The original pH levels for experiments I, II, and III were 7.5, 6.5, and 5.5. For the investigation, low nitrogen and phosphorus concentrations were used (ammonium = 0.91 ? 0.36 mgN/L, nitrate = 0.50 ? 1.40 mgN/L, phosphate = 0.23 ? 0.10 mgP/L). Using an ICP-OES, cadmium concentrations of 1 3 mg/L substantially decreased pak choi growth (p < 0.05). Due to cadmium solubility at acidic pH levels, the greatest concentration (2.67 ? 0.1 mg/L) was reported at pH of 5.5. According to USEPA method, an average daily intake of 1 3 mg/L cadmium-contaminated pak choi cultivated will not cause chronic non-carcinogenic (hazard quotient < 1) but can induce carcinogenic impact (cancer risk > 10-6) after 30-year consumption. Thus, thorough monitoring of cadmium in irrigation water is recommended. |
