Resumo(s)
The region of Estarreja is known for its strong industrial complex, composed essentially
by chemical facilities. For several years, several of these industries have discharged its solid
residues in an improvised park in the surrounding area, and conducted its wastewaters into a
stream nearby (“Esteiro de Estarreja”). Therefore, the levels of Pb, Zn, As and Hg in the
sediments of this stream, to a depth of 50 cm, are above the limits established by EC Directive
86/278/EC1. Nevertheless, in the banks of the stream, the vegetation remains proliferous.
Three plant species, present in a larger amount, were collected from that area and were tested
for the content of the above metals. The purpose of this study is to identify plant species
endemic to the site and to determine their ability to uptake heavy metals.
