Cartographie de la pollution atmosphérique par le plomb d’origine routière à l’aide de la transplantation d’un lichen bioaccumulateur Xanthoria parietina dans la ville de Tiaret (Algérie)

Abstract: Lʼobjectif de ce travail est dʼétablir une carte de la pollution par le plomb dʼorigine routière à lʼaide dʼun lichen transplanté dans différents sites de la ville de Tiaret (Algérie). Dans cette ville, lʼapport principal en plomb se fait par la voie atmosphérique, notamment par les émissions liées au trafic routier. Les émissions de Pb se font essentiellement sous forme de fines particules qui sont ensuite collectées par les thalles de lichen Xanthoria parietina. Quarante-six échantillons de Xanthoria parieti… Show more

“…Our results indiquate that Xanthoria pareitina accumulates much more lead than Ramalina farinacea (Maatoug, 2010), Low concentrations were noted in class 3 around the value 76.31 ± 2.19 µg/g, but still elevated compared with control sites. We can also divide this class into 3 subclasses whose lead levels are varied from 49.80 ± 4.78 at 60 ± 5.30 µg/g for the 1st subclass, from 60 ± 5.30 to 90 ± 2.80 µg/g in the 2nd subclass and from 90 ± 2.80 at 119 ± 5.20 for the 3rd subclass.…”

“…The study sites are located either at the intersection of the mesh, in the middle of each mesh (mesh size of the territory of 0.5 km x 0.5 km) (Garrec and Van Haluwyn, 2002). On total, 48 lichen samples were transplanted in different sites in the city, and each lichen sample is set in a tree trunk at 1.30 m high (Maatoug, 2010). The duration of transplantation was determined by one month (from April 21 to May 22, 2008).…”

“…Les approches appliquées ont consisté à doser les éléments traces métalliques (Pb, Cd Zn, Cu, etc.) dans les thalles du lichen Xanthoria parietina dans différents sites de quelques agglomérations algériennes (Samadi, 1993 ;Rahali, 2003 ;Maatoug, 2010 Le climat est de type méditerranéen avec un régime pluviométrique variable laissant apparaitre deux saisons bien distinctes l'une pluvieuse qui s'étend de septembre à avril, et l'autre chaude et sèche. Ce ci exprime le contraste très important qui sévit durant l'année.…”
