Effet de la pollution atmosphérique par les hydrocarbures sur le lichen Xanthoria parietina (L.) Th (Teloschistaceae) dans la zone de Hassi Messaoud (Sahara septentrional algérien

Abstract : This work is focused on bio-detection air pollution by hydrocarbons in the area of Hassi Messaoud Ouargla region (Northern Sahara Algerian East). Lichens collected on their support in the northeast of Algeria (Annaba), are used as a biological model to assess the effects of this pollution transplantation for 75 days. The levels of soluble compounds in hexane (CSH) at the lichen transplants increase and then decrease during the exposure time. With respect to the chlorophyll content, it decreases as the sampling period. The changes observed over time could have originated two causes of air pollution on the one hand and dehydration thalli under the effect of the temperature of the other areas.
