The average value of the 5 heavy metals contamination coefficient was between 0.03 and 4.33 indicating high level of contamination. Cd had the largest contamination coefficient, especially in sample locations ODS-3 and ODS-5 with values 7.8 and 6.4 respectively indicating severe contamination. Therefore, targeted pollution control and management measures are urgently required to prevent the increase of Cd contamination and to limit potential harm.
