The results of an investigation of heavy metal air pollution in Lamdong province (Vietnam) using the moss biomonitoring method are presented in this paper. Barbula Indica moss samples were collected at 30 different locations in Dalat and Baoloc, two major cities of Lamdong province. The concentrations of 10 heavy metal and metalloid 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 using the nuclear reactor at the Nuclear Research Institute in Dalat. The results show that the air in Lamdong province may be polluted by Mn and is moderately polluted by Sc, V, Cr, Fe, Co, Zn, As, Hf and Ta. The main sources of heavy metal pollution in the Lamdong atmosphere may be soil dust, traffic emissions, industry, bauxite mining and refining, chemical fertilizers and pesticides, and combustion of coal and oil. By comparing heavy element concentrations in the moss from Lamdong with that of Hanoi, Thainguyen, and several European countries, it is found that heavy metal air pollution in Lamdong is much lower than in Hanoi and Thainguyen and much higher than in the European countries.

“…However, these moss species are rarely found in Asia. Instead, other mosses have been used: Hypnum plumaeform in China 15 , Hypnum plumaeforme and Taxithelium instratum in Malaysia 16 , Thuidium tamariscellum in the Philippines 17 and Barbula indica in Vietnam [18][19][20] . In this study, samples of Barbula indica moss were collected at different locations in Bao Loc.…”

“…Our results can be compared with previous studies in Vietnam that also use Barbula indica moss but with different detection techniques. In Table2, the mean elemental concentrations in moss samples from our work are compared with previous studies by Doan Phan19 and Khiem20 . The comparison shows that the number of elements in our research is greater than that in previous studies, despite Ho Chi Minh City (the largest city of Vietnam) and Hanoi (the capital of Vietnam) having more pollution sources.…”

Introduction: Due to industrial development, agriculture, and urbanization, environmental pollution is a serious problem worldwide. In particular, air pollution is becoming increasingly serious. To evaluate the impact of air pollution in major cities of the country, various methods of air collection and treatment and assessment through monitoring stations are being developed. However, the main disadvantage of the installation of monitoring stations is the cost of investment for operations, maintenance, and equipment. In this study, to reduce costs, Babular Indica moss was chosen as a biological indicator. Two techniques, NAA and TXRF, were combined to increase the number of trace elements detected in moss samples. Methods: A combination of two multielement analysis techniques, NAA and TXRF, are used to detect trace elements from atmospheric deposition in Barbula indica moss collected in Bao Loc, Vietnam. Results: The two methods are highly complementary, allowing us to determine 42 elemental concentrations in 11 moss samples. Twenty-nine elements were identified with NAA: Na, Mg, Cl, K, Sc, V, Cr, Mn, Fe, Co, Zn, As, Se, Br, Rb, Sb, I, Cs, La, Ce, Sm, Eu, Tb, Dy, Yb, Hf, Ta, Th and U. Twenty-four elements were identified with TXRF: Al, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, Rb, Sr, Y, Ag, Sn, Sb, Ba and Pb. Eleven elements were identified by both techniques. Conclusion: This study shows that NAA and TXRF combine efficiently and provide a more comprehensive detection of trace elements in moss samples than is possible with either technique alone.

Comparison of moss bag and native moss technique in monitoring airborne particulate and toxic elements

Introduction: In Vietnam, the government has invested in monitoring stations in a few big cities like Hanoi and Ho Chi Minh City, which have transportation centers and industrial zones, to assess and predict levels of air pollution. However, the main disadvantage of installing monitoring stations is the cost of investment for operations, maintenance, and equipment. It is also time-consuming to collect and analyze the results. Therefore, it is generally not suitable for the country as a whole. Methods: Using mosses to monitor air quality brings qualitative and quantitative data with simple, environmentally-friendly economic methods. Mosses have particular biological characteristics that make them very suitable adsorbents for a wide variety of chemical elements. When used as transplants like moss bags, allow them to monitor a highly dense sampling network of any site easily. Mosses are bioindicators, plants with artificial roots. Results: In this study, moss bag and native moss were the two methods used to evaluate the accumulation of trace elements in air through Barbula Indica. Observations showed that both methods could detect the same elements: Al, Si, P, S, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, Rb, Y, Sb, Ba, Pb, and U. However, the accumulation of the elements in native moss is higher than in moss bag. The main reason is that the absorption efficiency of native moss in air-deposited elements is higher than in moss bags. Conclusion: Moss bags have been used most extensively and successfully in urban areas, where vegetation samples are either unobtainable or are poorly located to the source. These areas can lack moss, or the native moss simply does not grow during the dry season.
