Method The levels of iron, copper, zinc, lead, cadmium, nickel, chromium, and manganese ions in the leaves of thirty five date palm （Pheonix dactylifera） samples collected from various levels of traffic in the streets of Denizli-Turkey were determined by graphite furnace or flame atomic absorption spectrometry. The wet, dry, and microwave digestion procedures for the date palm （Pheonix dactylifera） leaves were compared. The accuracy of the digestion procedures was checked using a standard reference material （IAEA-336 Lichen, SRM）. Results Microwave digestion procedure for the leaves was preferred because it was more proper with respect to both time and recovery than dry and wet digestion. The levels of the heavy metal ions investigated were the highest on the samples from high traffic level. Also correlations between metal levels and traffic volume for all the metals were investigated. Conclusion In the light of our findings, the date palm （Phoenix dactylifera） leaves are suitable as a biomonitor for atmospheric heavy metal-polluted traffic. Significant correlations can be obtained between traffic levels and heavy metal concentrations.展开更多

The Babada and Honaz fault zones are generally made up as nearly E-W directed two segments. The Pamukkale fault also contains many overlapping segments in the Denizli area along the NE margin of the graben. The DG contains an NW-SE trending horst （Karakova） controlled by normal faults with oppositely dipping high angles and that truncate the Plio-Quaternary rock units. The faults that bound the DG are likely to have been initiated during the Early to Late Miocene and appear to be active today. The faults of the DG are active and the potential energy that accumulates in them is easily conducted to the other faults that they come in contact with. This signifies that a movement in one of the faults forming the grabens in the Denizli region affects the other structures as well. Earthquakes in the Buldan region usually occur 2-3 years after seismical movements occur in the Denizli Basin. The Buldan region is a ridge between DG and Ala ehir graben （ALG）. Based on the fact that DG in its south and ALG in its north move seismically, there is a probability that a break would appear in the Buldan region in the near future.展开更多
