Avaliação das condições ambientais da lagoa de Varano, no sul da Itália

In the sediments of Varano lagoon (South Italy) were evaluated the concentration of some toxic heavy metals. Besides in the same sites were determinated the bioluminescent inhibition of eluate sediments by Toxalert® 10 and all matrix datas comparated with biological classification proposed by author Frisoni based on abundance level of macrozoobenthos. The results from three tipes of approches (ecotoxicological, chemical and biological ) show a similar trend.
