| description |
The results of an investigation of heavy metals air pollution in Lam Dong province
(Vietnam) using the moss biomonitoring method are presented in this paper. Barbula Indica moss
samples were collected at 30 different locations in Da Lat and Bao Loc, two major cities of Lam
Dong province. The concentrations of 10 heavy metals and metallic elements, Sc, V, Cr, Mn, Fe,
Co, Zn, As, Hf, and Ta in the collected moss samples, were determined by the neutron activation
analysis method based on k0 standardization using the nuclear reactor at the Nuclear Research
Institute in Da Lat. The results show that the air in Lam Dong province may be polluted by
Mn and is moderately polluted by Sc, V, Cr, Fe, Co, Zn, As, Hf and Ta. Factor analysis was used
©2023 Vietnam Academy of Science and Technology330 Investigation of elemental deposition in Lam Dong province (Vietnam) by the moss biomonitoring method :::
to find six main factors that characterized the expected pollution sources. The main sources of
heavy metal pollution in the Lam Dong atmosphere may be soil dust, traffic emissions, industry,
bauxite mining and alumina refining, chemical fertilizers and pesticides, and combustion of coal
and oil. By comparing heavy element concentrations in the moss from Lam Dong with that of
Hanoi, Thai Nguyen, and several European countries, it is found that heavy metal air pollution in
Lam Dong is much lower than in Hanoi and Thai Nguyen and much higher than in the European
countries. |
