Environmental fate and microbial degradation of aminopolycarboxylic acids

Abstract: Aminopolycarboxylic acids (APCAs) have the ability to form stable, water-soluble complexes with di- and trivalent metal ions. For that reason, synthetic APCAs are used in a broad range of domestic products and industrial applications to control solubility and precipitation of metal ions. Because most of these applications are water-based, APCAs are disposed of in wastewater and reach thus sewage treatment plants and the environment, where they undergo abiotic and/or biotic degradation processes. Recently, also… Show more

“…Although EDTA is very effective in mobilizing metals in soils, EDTA and EDTA-heavy metal complexes can be toxic to plants and soil microorganisms and they can be also persistent in the environment due to their low biodegradability (Bucheli-Witschel and Egli, 2001;Grčman et al, 2003).…”

“…Chelating agents occur in natural waters predominantly as metal complexes. There are many studies emphasizing the importance of chelation on metal bioavailability, plant uptake, toxicity, transport, adsorption, distribution, and fate [3]. However, the identification and detection of these metal complexes in environmental sample is still a significant analytical challenge because of their structural similarities and presence at low concentrations in environmental matrices [4].…”

“…However, potential side effects related to the addition of chelants, such as metal leaching to groundwater, have led to health, safety, and environmental concerns. Many synthetic chelants and their complexes with heavy metals can have negative effects on the environment (Bucheli-Witschel and Egli, 2001) and are poorly photo-, chemo-, and biodegradable in soils (Bucheli-Witschel and Egli, 2001;Egli, 2001;Kari and Giger, 1996;Nortemann, 1999). EDDS, a structural isomer of EDTA, is a promising new alternative synthetic chelant.…”
