Abstract: Recebido em 6/3/03; aceito em 28/4/03 EDTA: THE CHELATING AGENT UNDER ENVIRONMENTAL SCRUTINY. The chelating agent EDTA (ethylenediaminetetraacetic acid) is a compound of massive use world wide with household and industrial applications, being one of the anthropogenic compounds with highest concentrations in inland European waters. In this review, the applications of EDTA and its behavior once it has been released into the environment are described. At a laboratory scale, degradation of EDTA has been achieved; … Show more

“…Additionally presence of extensively used chelating agent ethylenediaminet etraacetic acid (EDTA) in varying aqueous environments and its subsequent effect onto increased metal species bioavailability including lead, is gaining attention as well (Swanson, 1984(Swanson, , 1985Riley et al, 1992;Vohra and Davis, 1998;Bargar et al, 1999;Kim and Ong, 1999;Palacios et al, 2002;Oviedo and Rodríguez, 2003;Xia et al, 2009). Though free aqueous phase lead species can be conveniently removed using traditional techniques such as metal precipitation, however, the presence of EDTA renders such processes either partially or completely ineffective because of a strong metal-chelate complex formation (i.e., lead-EDTA).…”

“…Environmental concentrations, usage, biodégradation and toxicology of aminocarboxylates have been thoroughly reviewed (2,(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19). Much less is known about the fate and behavior of the corresponding phosphonates in the environment.…”

“…They are also used in cleaning and washing agents and in many other industries. Their biodegradation is practically not observable in the biological stage of sewage treatment and they persist in the environment, consequently there are increasing concerns about their use 6,7 . They are also said to be insufficiently biodegradable and accumulate in the environment for as long as 15 years 7 -9 .…”
