Impact of aminopolycarboxylates on aquatic organisms and eutrophication: Overview of available data
10.1002/tox.20071.abs
Aminopolycarboxylic acids, which include ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA), diethylenetriaminepentaacetic acid (DTPA), 1,3‐propylenediaminetetraacetic acid (1,3‐PDTA), β‐alaninediacetic acid (β‐ADA), and methylglycinediacetic acid (MGDA), constitute a class of complexing agents that occur in a wide range of domestic products and that are used intensively as metal sequestrants in several industrial applications. Because they are highly polar and partially nondegradable, aminopolycarboxylates are released into the aquatic environment in significant quantities, mainly via wastewater. The historical and current use of aminopolycarboxylates and their ubiquitous presence in surface waters prompted many studies about their possibly detrimental impact on aquatic organisms. This review summarizes the available data and information on the eutrophication potential and toxicity of aminopolycarboxylates to a multitude of aquatic organisms including vertebrates, invertebrates, algae, bacteria, and protozoa. This article also addresses how the ecotoxic effects of aminopolycarboxylates are dependent on their speciation, that is, on their presence in a free or a metal‐complexed form. © 2004 Wiley Periodicals, Inc.
