Trace element transfer from soil to leaves of macrophytes along the Jalle d’Eysines River, France and their potential use as contamination biomonitors

摘要: Biomonitoring complements the physico-chemical analysis of environmental matrices, accounting for subtle biological changes in organisms affected by exogenous chemicals. Here, relationships between concentrations trace elements (TE) soil, soil-pore water and leaves seven rooted macrophytes (Ranunculus acris L., Phragmites australis (Cav.) Trin. Ex Steud., Carex riparia Ehrh., Lythrum salicaria Iris pseudacorus Juncus effusus Phalaris arundinacea L.) were investigated along an urban river – Jalle d’Eysines River, France with increasing TE contamination riverbank soils, from its source to confluence Garonne River. Copper, Zn, Cd, Cr, Pb, Ni, Mo As considered. Macrophytes sampled June 2011, at peak growing season. For five species, a canonical correspondence (CCA) was used assess correlations foliar total soil. Along P. are relevant biomonitors soil contamination. C. biomonitor Cd contamination, while R. is Ni Copper monitored by, respectively australis.
