Assessment of heavy metals potential ecological hazards of soil and health risk of bamboo shoots
摘要
Abstract
To investigate the potential ecological hazards of soil and the health risk of bamboo shoots consumption, the contents of five kinds of heavy metals(Pb, Cr, Cd, As and Cu)in moso bamboo shoots and soil collected from eight producing areas in Zhejiang and Jiangxi Province were measured by atomic absorption spectrometry, atomic fluorescence spectrometry and inductively coupled plasma mass spec-trometry. The result showed that average contents of Pb, Cr, Cd, As and Cu in soil were 35.5, 47.5, 0.22, 8.5 mg·kg-1, and 25.5 mg·kg-1, re-spectively. The highest content of Cd and Pb reached 54.2 mg·kg-1 and 0.58 mg·kg-1, which exceeded the limit value of LY/T 1678—2014. The content of Pb, Cr, Cd, As and Cu in all bamboo shoots were within the ranges of 6.0~39.7, 9.0~105.4, 0.70~19.9, 1.4~4.6μg·kg-1 and 322.0~1648.9μg·kg-1 respectively, which were lower than the threshold values of LY/T 1777—2008 and GB 2762—2012. The individual potential ecological risk index of Cd was in the medium level of the risk, while the comprehensive potential ecological risk index of five kinds of heavy metals was in low level. The accumulation rate of all five kinds of heavy metals in edible part of bamboo shoots was in low level. The hazard index(HI)of five kinds of heavy metals through consumption of bamboo shoots ranged from 0.059 to 0.57, which were lower than the maximum allowance levels recommended by USEPA. Therefore, the intake of moso bamboo shoots would not bring risks to residents.关键词
