Overview

Study assesses contamination and health risks of hazardous elements in sediment, suggesting urgent pollution control measures.

Key Points

  • Sediment contamination levels showed PHEs surpassed upper continental crust values, indicating significant pollution.
  • Ecological risk assessments suggest low toxicity effects, with non-carcinogenic risks for hazardous elements below 1.
  • Anthropogenic sources for certain elements were identified, particularly linked to mining and urban runoff activities.
  • The study employs multi-index and multivariate methodologies for comprehensive assessment and calls for enhanced environmental management.
