主 题：Senecio bonariensis Phytoremediation Arsenic Underground water
摘 要：The use of plant species to cleanse groundwater with excessive concentrations of arsenic(As)derived from contact with weathered materials has become a valuable option to treat *** aim of this work was to analyze the bioaccumulation capacity of As of Senecio bonariensis(Asteraceae)through controlled laboratory tests and uncontrolled trials in the field in order to generate a low cost method applicable in rural areas that do not have systems of water *** collected from the natural environment were arranged in hydroponic crops under controlled and uncontrolled conditions,in the first case with increasing concentrations of As for 45 days,and in the second,with a constant concentration of As for a period in a range between 45 and 90 *** plants were processed and dried for the measurement of *** both tests,in all the samples there was a noticeable accumulation of As,generally greater in roots than in *** controlled conditions the plants accumulated more As in relation to greater concentration of this element in the *** all the trials a high bioaccumulation of As was found,which turns the plant into a *** to the ability of *** to accumulate As,and even more because of the great biomass produced by this species,it becomes an excellent one to be used for the remediation of arsenical waters.
