AN ANALYSIS OF SEVEN METAL ELEMENTS IN LUNG CANCER
TISSUES IN GUANGZHOU, CHINA POPULATION
Zhong Sai-xian, Chai Cheng-keng, Zhao Zhen-xin
and Chen Cheng-zhang
Department of Environmental Health,
Sun Yat-sen University of Medical Science,
Guangzhou, China
The role of metal elements in the development of cancer has been a matter of concern in recent
years. We have made an analysis of seven metal elements (Mn, Mg, Zn, Cd, Cr, Ni, Cu) contained in
the lungs of 10 lung cancer patients (observed group) and 10 normal subjects (control group) from
the
Guangzhou population, using an atomic absorption spectrometer. (Table 1)
From the data, it can be seen that, among the 7 metal elements measured in the observed group,
3 metals (Mn, Mg, Zn) were significantly increased compared with those in the control group (P <
0.05).
We believe that some metal elements might play an important role in the pathogenesis of lung cancer
and
that the sources of these elements in our bodies might be quite different. Some of them, for
example,
Mn, Cd and Ni, might arise from atmospheric pollution and others, such as Zn and Cu might be related
to our dietary habits.
