Overview

Assessment reveals significant health risks from heavy metal exposure in crops, highlighting urgent monitoring needs.

Key Points

  • The total hazard quotient for adults is 2.365 and for children is 1.176, both above the safety threshold.
  • Carcinogenic risk for adults is 2.28 × 10 − 3 and for children is 1.11 × 10 − 3, exceeding the unacceptable risk level.
  • Heavy metals arsenic, chromium, cadmium, and nickel significantly contribute to health risks in the populations studied.
  • Long-term consumption of crops with high heavy metal content poses serious health concerns, necessitating effective control.
