摘要
The aim of this article is to determine the air quality and to monitor the effects of pollution in Elazig, Turkey using plants. For this purpose, nickel (Ni) and chromium (Cr) concentrations in three plant species were determined. The leaves of the Pinus nigra L., Cedrus libani, and Cupressus arizonica together with soil samples were collected from different points depending on traffic intensity, proximity to the city center and cement factory, as well as control locations during different months of the year. Flame atomic absorption spectrophotometry (FAAS) was used for measurement of the metals in clear digests after the dry ashing method. Nickel and Cr concentrations were in the range from <LOD to 1.03mgkg(-1) and <LOD to 0.83mgkg(-1) for Pinus nigra L., 0.41 to 2.06mgkg(-1), and <LOD to 0.68mgkg(-1) for Cedrus libani, and <LOD to 1.47mgkg(-1) and 0.16 to 0.77mgkg(-1) for Cupressus arizonica, respectively. The levels observed for Ni and Cr in the soil ranged from 10-63mgkg(-1), and 6.0 to 43mgkg(-1), respectively.
