| Abstract | The Tha Chin River, located in the central of Thailand, has a significant residential area, agricultural site, and industrial site. In this study, the heavy metals (As, Cd, Pb, Ni, and Zn) contaminated in the river in the dry and wet seasons were evaluated at Chai Nat, Pho Phraya, Song Phi Nong, Bang Len, Sampran, and Tha Mai stations. The water spinach (Ipomoea aquatica Forssk.) and water mimosa (Neptunia oleracea Lour.) grown in the Tha Chin River were collected and analyzed for heavy metal concentration using inductively coupled plasma mass spectrometry (ICP-MS). The result showed that the heavy metal concentration in water at all stations was below the standard limit in dry and wet seasons. The accumulation of heavy metals of water spinach, and water mimosa in edible parts was in order of Zn > Ni > Pb > As > Cd. The non-carcinogenic health risk revealed that Hazard Quotient (HQ) and Hazard Index (HI) of water spinach and water mimosa were below the threshold limit. The cancer risk assessment based on the ingestion of both plants indicated that As, Cd, and Ni might pose to high lifetime cancer risk. This finding will be applied for proper management in the Tha Chin River to avoid the risk for the residents. |
