Poirier-Duchêne N. Galand and M. Subirana Summary The elemental analysis of 150 French acacia honeys Robinia pseudoacacia L. collected by beekeepers in apparently polluted and nonpolluted environments was performed by using inductively coupled plasma atomic emission spectrometry ICP-AES to measure significant concentrations of Ag Ca Cr Co Cu Fe Li Mg Mn Mo P S Zn Al Cd Hg Ni and Pb. Fortunately Cd Hg Ni and Pb were not detected in the analyzed samples. Conversely Ag Cu Al Zn and S were found in some samples located near industrial areas. Because a high variability was found in the concentration profiles correspondence factor analysis was used to rationalize the data and provide a typology of the honeys based on the concentration of these different elements in the honeys. The results were confirmed by means of principal component analysis and hierarchical cluster analysis. Finally the usefulness of the acacia honey as a bioindicator of heavy metal contamination is discussed. Introduction The continued expansion of industrial production and the growing use of chemicals in agriculture have led to an increase in the number and quantities of xenobiotics released into the different compartments of the biosphere 1 . The health risks to human and nonhuman biota associated with these chemicals are evaluated on the basis of critical and reliable information on exposures and on related adverse health effects 2 . In this process the estimation of the environmental concentrations of the hazardous chemicals plays a key role. A number of precise technical sampling methods are available for monitoring pollutants in the environment. However due to their high technicality and cost they are generally not used routinely 2 . Conversely bioindicators are now widely employed for estimating at low cost the level of contamination of organic and
