Accumulation of As, Cd, and Pb in Sixteen Wheat Cultivars Grown in Contaminated Soils and Associated Health Risk Assessment.
Int J Environ Res Public Health. 2018 11 21; 15(11)IJ

Abstract

This study investigated the accumulation of As, Cd, and Pb in 16 wheat cultivars and the associated health risks for the inhabitants of Jiyuan, China. The results indicated that the concentrations of As, Cd, and Pb decreased in the order of root > leaf > stem > grain. The concentrations of As, Cd, and Pb in wheat grains varied from 0.13 for Pingan8 to 0.34 mg kg-1 for Zhengmai7698, 0.10 for Luomai26 to 0.25 mg kg-1 for Zhengmai7698, and 0.12 for Zhoumai207 to 0.42 mg kg-1 for Zhengmai379, respectively. There were significant differences in the bioaccumulation factors of As, Cd, and Pb among the 16 wheat cultivars. Cd was more readily accumulated to higher levels than As and Pb in wheat. The Target Hazard Quotients (THQs) of Cd and Pb in the grains from 16 wheat cultivars were below 1, while As THQ exceeded 1. The lowest detrimental human health effects via wheat consumption were found in cultivar AY58 among the 16 wheat cultivars, with total THQs (TTHQs) of 1.82 for children and 1.60 for adults, suggesting that children absorb more heavy metals than adults and they are more vulnerable to the adverse effects of these metals.
