Use of commercial sphagnum to estimate the geographic impact of a battery of recycling plant

Abstract : A technique of biosurveillance (moss-bags) is used to evaluate thé heavy metal depositions (lead, cadmium, arsenic, barium and antimony) around an industrial source. The results are compared with those obtained by the use of gauges of sedimentation and by modelling of the emissions from stacks. The moss-bags prove to be as good qualitative tools as the gauges of sedimentation. It also appears that the moss-bags have a greater effectiveness to collect the atmospheric depositions than the gauges of sedimentation and that, in spite of a smaller surface of exposure. Fifteen days duration is sufficient to collect quantifiable levels of lead, cadmium, antimony and barium, in the moss-bags placed in the vicinity of the studied site. However, the speed of accumulation of heavy metals in the moss-bag does not seem to be constant in time. This makes delicate the comparison of results of campaigns carried out over different durations and perhaps periods. This study validates the use of sphagnum mosses of culture to make some moss-bag, thus mitigating the difficulty of provisioning related to the use of "natural" sphagnum mosses. The use of this technique, that requires a minimum number of measuring points, made possible a quick evaluation of the site's contribution in lead, cadmium, arsenic and antimony, deposition measured in its vicinity. In comparison, the modelling of exhaust gases and particulates of the site provided incomplete qualitative information because of the presence of diffuse sources. This tool of powerful qualitative survey (confidence interval reduced, cost effective, ease of use, discrete, light technique) can bring essential information where other approaches are more uncertain (modelling in degraded situation) or require to be optimised (standardized quantitative methods).
