Ecological and health risk assessment of rare earth elements in Kaifeng, Henan Province: a Monte Carlo probabilistic approach
Abstract As rare earth elements (REEs) are increasingly used in production and daily life, the threat that REEs in urban soil pose to human health has become increasingly prominent. This study focused on urban soils in Kaifeng City. A total of 70 surface soil samples were collected to determine the concentrations of 13 REEs and conduct a risk assessment.
