Elemental concentrations in air, water, and aquatic biota in two rural provinces in northern Vietnam
Artikel i vetenskaplig tidskrift, 2007
The present study on environmental pollution in northern Vietnam investigates elemental concentrations in fine particulate matter (PM2.5), freshwater, and aquatic biota at two sites with differing levels of industrial activities. An Thin is situated 47 km cast of Hanoi in the neighbourhood of a coal combustion power plant, whereas the reference site, Duy Minh, is situated in the agricultural province of Ha Nam, 40km south of Hanoi. Elemental concentrations were analysed using energy-dispersive X-ray fluorescence, total reflection X-ray fluorescence, and graphite furnace atomic absorption spectrometry. All investigated elements in fine particles (PM2.5) had significantly higher concentrations in An Thin, thus identifying the air at this site as polluted. In contrast to the aerosol samples, elemental concentrations as well as quantitative differences between the sampling sites were low in freshwater and biota, indicating that the impact of atmospheric deposition was limited.
