Accumulation of Heavy Metals in Vegetable Species Planted in Contaminated Soils and the Health Risk Assessment.

Furthermore, the Pb concentrations in edible parts were found to be highly significant positively ( p < 0.01) correlated with the concentrations of Cd, Zn, and As, and the correlation coefficients ( r ) were 0.872, 0.870, and 0.754 ( n = 22, r 0.01 = 0.53), respectively; the Cd concentrations were highly significant positively ( p < 0.01) correlated with the concentrations of Zn and As, and the correlation coefficients ( r ) were 0.806 and 0.784, respectively; the As concentrations were highly significant positively ( p < 0.01) correlated with the Zn concentrations ( r = 0.649).
