Analysis and Assessment of Heavy Metal Content of Lonicera Hypoglauca and Soil from its Producing Area in Guizhou Province
[Objective] The purpose of this study is to research the heavy metal pollution of Lonicera hypoglauca and soil of its producing area
in order to provide guidance for quality guarantee
origin of prevention and control of soil heavy metals and good agricultural practices of L. hypoglauca.[Methods] We collected L. hypoglauca and the soil samples from Guizhou Province. The contents of Cu
As
Pb
Cd
Hg
Cr were detected by the ICP-MS. Single factor pollution index and comprehensive pollution index were calculated.[Results] The average contents of As
Pb
Cd
Cr
Hg and Cu in soil were 9.79
14.30
0.10
19.89
0.12 and 3.81 mg/kg
respectively
which satisfied the requirements of national standard(GB15618-1995). The comprehensive soil pollution indexes at root zone and non-root zone were 0.46 and 0.83
respectively
which was safe and below the warning line. The average contents of Cr
As
Cd
Pb and Cu in flower were 5.19
0.16
1.87
0.39 and 6.86 mg/kg
respectively
and Hg was not detected in the flower. The content of Hg
As
Pb and Cu satisfied the requirements of national standard(WM/T 2-2004). The average content of Cd was far beyond the limited level
indicating that L. hypoglauca had a strong ability to concentrate Cd.[Conclusion] Soil environmental quality in the study area is suitable for planting L. hypoglauca
