标题：THE EFFECT OF HEAVY AND ALKALINE METAL ACCUMULATION ON THE CHLOROPHYLL CONTENT OF FONTINALIS ANTIPYRETICA HEDW. AND MARCHANTIA POLYMORPHA L. FROM IDA MOUNTAIN
摘要：Fontinalis antipyretica Hedw. is specially a pollutant-sensitive indicator species in fresh water and Marchantía polymorpha L. is commonly found on moist clay or silty soils, especially on recently burned land throughout the northern hemisphere. F. antipyretica and M. polymorpha were examined to determine the quantity of metal accumulation. Samples were collected from Ayazma Stream (Ida Mountain) with similar exposure conditions in July 2017. Mosses are suitable species for the uptake of heavy metals because of their morphological and physiological properties. Because of this, studies on the use of mosses as an environmental monitoring have increased in last decades. In the present study each sample were irrigated for 72 hours with solutions 0, 02 M CuCl_2, ZnCl_2 and Pb(NO_3)_2. At the end of the experimental period, the chlorophyll concentration of F. antipyretica and M. polymorpha was decreased. There was significant reduction of the chlorophyll content for each sample due to the heavy metals accumulation.
